Great little heater for my apartment bathroom
January 22, 2017
The ideal size for my small bathroom. I've been an exclusive user of oil-filled heaters for the past 15 years. They're economical and efficient. Once they are warmed up, the air around them is extremely comfortable. This is the smallest one I'd ever seen and had to try it. It works great and can even overheat the bathroom if the user doesn't understand how this type of heater works. The settings allows it to adjust the temperature perfectly. It takes up barely any space, as it's so thin, which is exactly what I needed.
Good Product but Waaay Overpriced
November 18, 2016
Very neat little heater for small areas, I put this one by my dog's sleeping area and he's very thankful I did. It is, however, very overpriced for what it is.

Just switched to this after purchasing several ceramic fan heaters in a row, each of which lasted about 6 months. Not sure about the durability of this product yet, but amazed by the difference in noise level. This is absolutely silent, it fits under my desk and works great.
Nice compact quiet heater.
October 25, 2016
Heats up, and keeps warm a 10x10 room nicely. Compact and light weight also. Got another. One for the cat room also, which is a slightly bigger room, and doesn't seem to have problems keeping it at about 68degrees.
The Perfect 'Under Desk' Heater
September 6, 2016
This is the perfect 'under desk' heater! It gives out even heat unlike the fan ones. It also has no smell! I wish I bought this years ago. It is slim, silent, and just perfect. I was always cold in the office, especially during the summer when the A/C was on full blast. Now I am nice and comfy, not too warm and not too cold, but juuuuust right.
January 7, 2016
Use this at the office in New Hampshire. Keeps the chill off that comes in through the poorly insulated windows behind me. I have it sitting on a large bay-window shelf and it sends warm air out so my back, neck and shoulders stay warm. There is no fan or blower, this is radiant heat from the heated oil inside the unit. It makes no noise. It is a thin unit, only a 1.5 inches thick.NOTE: There is a caution notice on the unit: "High Temperature; keep electrical cords, drapery and other furnishings at least 3 feet from the front of the heater and way from the side and rear."
Great Heater for the upcoming cold Winter months.
September 16, 2017
As soon as I purchased this heater, the weather turned extremely hot and muggy. On a few very cool nights, I fired it up and it worked very, very well. It has several features that are necessary for feeling the warmth it produces. It has a very good thermostat and hi and low features that work very well and that are very sensitive for what they do. I live in an apartment building that does not turn the main heat on until late October, for tenants in their own apartments. Last year, the cold came on quite early in the season and sitting around watching TV or taking a late shower before bed or early in the morning became quite painful, with the lack of heat. The DeLonghi Heater has cured this problem as soon as I turned it on. I am looking forward to many cold days and evenings with the DeLonghi Heater.

Works as expected; no problems. I wasn't sure about the ComforTemp feature at first, but I found a use for it. I keep the unit adjusted so it keeps my small shop just over 40 degrees. When I'm going to be working in the shop I press the ComforTemp button to warm up the shop to approximately 65 degrees without having to change the thermostat setting. Turn if off when done working and the room temperature will gradually go back down to the regular setting.If you're not familiar with electric radiators, they don't heat up super fast, but they do heat up a room or an area very nicely given enough time. When the unit is drawing the full 1500 watts, it costs about $0.13 per hour to run, depending on your electric rates. When a room is already warmed up, it costs a fraction of that to maintain the temperature.
Great heater except a few minor issues
December 7, 2016
We have been using two of these to heat our master and kid's bedroom during cold Chicago nights. We recently moved to a house, which is of course more difficult to keep warm compared to our previous 2 bedroom condo. That's where these heaters come in. We drop the furnace thermostat to low setting so it only kicks in at most once during the night. One of these heaters is powerful enough to keep a large bedroom pretty cozy at only Min power setting (700W; max is 1500W) and the thermostat fixed at 3 (goes all the way up to 6). In the morning raise the furnace thermostat up and turn the Delonghi heaters off and we are ready to start the day.Pros:* Allows me to control the temperature of the bedrooms pretty accurately. Learning the correct settings for my house took only a few tries.* Cheap to use compared to heating an entire house, while occupying only two rooms during cold nights. Even if it runs at 1500W non-stop one of these would only use about $4 of electricity a day and that amount of heat would turn your bedroom into a Turkish bath.* really lightweight. If I need to carry the heaters downstairs, say. I can carry two of them at once.Cons:* Impossible to see the thermostat in dim light.* the wheels are somewhat flimsy in my opinion.Tips:* Heating a space from a really cold state would take a long time with these. These devices are best if they are used to maintain the temperature.* Bring the space you want to heat to the temperature you like. Lower the thermostat on the heater until it clicks (turns off) and leave it there. That is probably the setting you want. Adjust as you like. To conserve energy set it to the Min setting. Power at min, thermostat at 3 is what I use for our large bedroom.* I didn't "temper" the heater before using. I didn't have the smell issue in first use that others claim.* I don't understand why forced air is a thing for heating houses. Radiators should definitely be the way to go. Think of the heat retention properties of cast iron vs. aluminum pans. same logic. heating air vs. heating solid mass.
Excellent heater with more temp range than most!
November 21, 2016
I have neen using oil filled radiant heaters for years and they're all pretty good.. The special thing about this brand and model, is that it has a greater range of temperature than others.. This can be important.. My Pelonis( NY1507-14A) Is often too hot for the situation at its lowest lossible setting(Economy 65°) But this DeLonghi has a much lower starting temp setting, that Ive found very useful.. I can easily maintain a comfortable temp in my very travel trailer with it..when I would "burn up" on the lowest Pelonis setting.
April 7, 2016
Great heater. Just keep in mind that this is for one room only that has 4 walls and a door, not for a huge space. Also, do not expect this to heat a freezing area quickly like a traditional electric heater because it does not work like that. If you want it to work as best as it can in a really cold area then you need to LEAVE IT ON. For example, I live in a house that is like an IGLOO in the winter, the heat is broken this winter so I had to get a heater but cost was a concern so a typical electric heater wasn't an option. My bedroom can get so cold that I can see my breath and I put this on full power and it was able to warm up to 60 degrees in about 10 hours, and it wont continue heating to like 90 degrees either, so you still need to bundle up a bit if its frigid. So don't expect your space to be nice and toasty in a matter of minutes or an hour, this takes a while but once its on for a few hours it is a great device. If you can just keep it going, you can adjust the setting and keep it on a minimal setting through the night or when you aren't home, but keep it on. Make sure you use common sense and read the instructions and warnings. Let it have its own outlet and keep flammable items away. It does get hot but not scalding, if you bump into it you have a few seconds before it gets uncomfortable. I love this heater, saved my life this winter, no joke. I would have frozen to death without it.
All the options you need. Pretty simple control panel.

I've owned the Honeywell 7-Fin Oil-Filled Radiator for several years now and intended to get another of the same, since I love it, I'm used to its controls, and it's never given me any problem. This one was being sold for a better price, so I got it instead.Comparison:As others have mentioned, the Honeywell radiator does tink and creak from time to time (a sound which I find quiet, cozy and wintry, not irritating). This DeLonghi is 100% silent.The Honeywell has a digital temperature setting, which I've always liked. I know that 67 will keep the room warm and the default 70 will make me feel claustrophobically sweaty if I leave it on that way and fall asleep. This DeLonghi radiator has a * - 6 dial, which is a more abstract gauge. BUT it also this giant button on the bottom which overrides the dial and runs it for "optimal recommended temperature (68-70)." Then it has the * setting, which makes it turn on only when temperatures approach freezing. Honestly, those two options have me pretty much covered, so that makes the DeLonghi faster to turn on. So, if you're really particular, or you're using it in a small room, maybe a digital dial is better, but if you're using it in a large room or a drafty room and you just want an average temperature - this model simplifies things.Both Honeywell and DeLonghi allow you to choose between low-medium-high operation level. The Honeywell is a little putzy because you have to crouch there waiting 7-10 seconds for the digital display to flash through its default settings before you can use the buttons to adjust them. And of course you just keep mashing the buttons up and down anyway, because you're too impatient to wait 7 seconds. The DeLonghi has two switches, which can be oriented in 3 different ways (left one up, right one up, both up). Which is faster to set, but I do find the logic a little weird (press low and medium to get high!).Other than that, they both seem the same, and I'm happy with both! Oil-Filled Radiators are so awesome. They are so quiet, their lifespan is longer, and they seem to do the job better (at least to me). Unless you're the kind of person who really craves the feeling of hot air being blown on them, this is the way to go, whatever brand.
Use it in my cubicle. Works fine!

I keep it under my desk at work. It definitely takes the chill off. Its only half the size of a normal one. So no one even knows its under my desk. The wattage is lower so less chance that it will blow a fuse.
Great small heater for small areas
December 29, 2016
Optimas Heater does exactly as I expected for $30. Tested it out today heating a 8x8 laundry room I just sheetrocked. About an hour, it had the room about 70 degrees. It is not a heater for bigger rooms. I would purchase the 1500 watt unit. I was looking for a heater that would heat up a small area that I could leave unattended without the fear a fire.Plan on using this heater in back of my work truck canopy over night when freezing temperatures outside, Keep my tools and liquid from freezing and also help drying out the inside of canopy shell so it doesn't start to build up mold.If you're looking for a small energy efficient radiator heater, this product works great in small tight areas. Wanting a small electric heater that has a fan, temperature setting that will heat up an area fast for under $30, buy Patton PUH680-N-U Milk-House Utility Heater - they work great but not as efficient but will heat up a room fast
The heater does a fantastic job for this size room
December 23, 2016
I don't know why people buy this small heater and then complain that it's not warm enough. I read the review and when I got it, I cranked it up for my granddaughter, it got so warm my granddaughter kicked all the blanket off. I had to kept adjusting down. It's been 3 days and I am still adjusting it down a bit at a time for her. We live in the bayarea and it's a 10'X10' room. The heater does a fantastic job for this size room. It gets warm quick too, not like the bigger ones I have.Of cause if you live in Alaska or Minnesota, you buy this for a big room and it's not warm enough, who's fault is that? You expect a tiny little heater that cost $37 to perform magic? If you size it right, it's a fantastic heater that doesn't take much room and only burn 700W electricity.
It's smaller than I thought, but sooooooo powerful.
August 13, 2015
It's smaller than I thought, but sooooooo powerful. Powerful enough for any small space. Very easy and simple thermostat control. Of course this is very portable, because it's small size.
Unusual being so small
March 11, 2015
Perfect for a small bedroom as on my boat where everything has to be small.It was a little stinky at first but I left it on high well ventilated and after it was good.
Fits well in a small space, low-cost to operate, but really is low power
March 3, 2015
My husband works from home and it get very cold in the winter here in WI and we don't want to pay to heat the whole house when he's the only one home. He uses this heater under his desk. It works well enough; and it's great that it doesn't use a lot of power. It fits the space and doesn't get too hot. It is very small and as a radiant heater, it's not really strong enough to warm a very large area and he ends up using a second space heater (the room he works in has two walls exposed to the outside).

This small unit does a great job in the small room
March 5, 2017
We use this heater to keep our RV bedroom warm on winter nights. This small unit does a great job in the small room. The feet are plastic and loosen up a little after use, causing the unit to wobble a bit (making a slight clicking noise) with RV movement. We wedge something under one foot to eliminate the wobble.
Works great in my small bathroom
February 20, 2017
This heater was perfect for one of my small bathrooms that gets a little cold in the winter. It's thin and easy to fit into the small bathroom and yet be out of the way. Being a radiant oil filled heater it takes a good while to heat up, but my intent was to raise the temperature throughout the day so it stays on and keeps the room comfortable.
I recommend getting a timer for the time you need it ...
December 8, 2016
Warms up a small/medium room well. Caution use this around adult only gets very hot to the touch. Makes cracking noise for the first 10 minutes and vice versa. Silent when on for a longer period. I recommend getting a timer for the time you need it on/off. Room stays warm even hours of being turned off.
... a heater that wasn't 1500 watt that would work good in my green house in the basement
December 21, 2015
Was looking for a heater that wasn't 1500 watt that would work good in my green house in the basement. Keeps a decent temperature in the green house (65 degrees on average). Basement has been around 50-55 degrees. We will see how long it lasts.My concern is that the plastics (feet and control panel) seem a bit flimsy. I guess as long as I don't kick it or tip it I will not break it. Of this is in a high traffic area I would be concerned.
So far so good
November 2, 2015
I purchased this to provide some warmth for my feet and legs when I'm sitting at my desk in the winter. My desk is in the middle of the room, and I have the heater sitting a couple of inches from the back of my desk. Does take the chill out of the air - it seems to help more when I turn it on about an hour before I start working. The unit itself gets very hot, but the desk itself doesn't absorb the heat - which I think is good. It definitely helps to provide some warmth - will be playing with placement as the weather gets even colder. I love the size and portability of the heater, and am glad to have some added heat without hot air blowing in the room and in my face, as I have had in the past.
February 6, 2015
This year one of the office salesmen brought in a 1500 watt heater and put it under his desk claiming his legs and feet are cold. I looked at his idea of a solution and all I saw was a ball warmer. I picked this up and replaced it under his desk before he came to work. He has been using it nonstop and there are no complaints. At least now he is warming his legs and feet.
I mostly love these heaters (bought two)
October 24, 2017
I mostly love these heaters (bought two). Only issue is with the thermostat...they don't seem to want to turn off. I put them on the lowest setting possible, they still crank heat. Could be I'm running them when it's too warm out (but I've been one of those always-cold women for years). Given I have cats, I like that these heaters are pretty much impossible for them to tip over, and are extremely unlikely to start a fire. Safe and effective, can't beat that.
First looks, everything is fine - except for the manual
September 23, 2017
Sept. 23rd, 2017: I may adjust this review as time goes on (if I can find it again).4 stars upon receipt and a week of operation:There was very little smell that others have noted in their review. I ran it for a hour or so outside. It was undamaged and arrived quickly. I've had in running 24/7 for about a week with no issues. The power cord does come out of the front of the unit. I don't find this to be a problem, but I don't have little kids running around. And if you turn the unit so the front faces the wall, the back of the unit gets very hot, very hot. So again, maybe a problem with little kids.There's no fan. The unit heats up, the heat rises. I have a ceiling fan with a slow spin near where I put the heater so this works out well for me. You don't get a warm breeze from this thing. It heats up, the heat rises.I won't go into the details of my domicile, but I'm going to be asking a lot of this heater. So if it struggles or fails to heat the entire place I won't be mad. I've purchased an additional small heater with a fan so I can do spot heating in the bathroom and kitchen. So if it struggles or fails to heat the entire place I won't be mad.Ok, so the reason I'm not giving it 5 stars right out of the box is because the manual is pretty poor. It doesn't really tell you how to turn it on just thatyou should have it set for ON when you plug it in. This is important, you can have all sorts of problems plugging in a live 1500 watts, fire being an outside possibility. (The on/off switches are vertical rocker switches and they are not labeled ON or OFF. When the top of the rocker switch is pushed in at the top, it's ON.) If you look closely you'll see above the two rocker switches, on the unit, the labels MED and MIN. And below them the label 0. So they are labeled and this maybe normal for this type of heater, but to me it's none standard. Picky I know, but then I've been around when someone plugged in something that shouldn't have been turned on when it was plugged in. The other thing is it has a Comfort button. Which the manual states will keep the heater at the optimal temp (or something like that). I'd like to know what the optimal temp is, some people are going to want the room at 75F, for me 55F would be great - I have sweaters. AND how does it know.So for starters things look good. I haven't had any of the problems I've been reading about. I'll try and keep this updated as the winter progresses.
delonghi is my only choice
December 16, 2016
Was given an old delonghi after having frozen pipes and it worked well for years but finally had to let it go as the cord/plug started overheating.Replaced it with this one and am very pleased with it.use in the bathroom to avoid frozen pipes.as I write this last night was 18* today it is only 20* for the high.Have had it on 24/7 with no problem.no odor,no noise.using it mostly at night when the temps here go below freezing.cheaper than a plumber ! my only complaint,it needs a longer cord.
DeLonghi EW7707CM Safeheat 1500W ComforTemp Portable Oil-Filled Radiator
February 18, 2016
DeLonghi EW7707CM Safeheat 1500W ComforTemp Portable Oil-Filled RadiatorLots of features like anti freeze, timer, multiple setting, silent, auto offCost $79.99Easy to use! I am trying to figure out the timer dial but I have never been able to do that so I won't hold it against the heater. It's great, easy, silent and gives all that it promises. The whole room heats up within 30 mins or so. I would definitely recommend this product for anyone that needs a space heater. It's heavy but the wheels helps!
February 1, 2016
I'm using this heater up in the Pacific Northwest. Daily temps usually hover around mid 40's and nightly temps usually drop into the mid to high 30's. Room size is 14x14 with a vaulted ceiling that goes up to 10 feet at it's highest point...and there's also a 6x4 foot attached bathroom that I leave the door open to. The heater handles the room and bathroom just fine although because of the door situation the bathroom stays cooler. Where this heater really excels is in providing slow consistent heat to maintain a comfortable temperature. The heater has no problem maintaining between 69-71 degrees. And it could easily go higher but that's what I find to be comfortable.The downside to this heater is that it's not ideal for quick heat...like in the mornings if the heater has been off all night and the room drops to 60 degrees. It will take 3-4 hours to bring the room back up 70. The heater can certainly do it but without a fan/blower it simply can't do it quickly. That's not what this heater is really designed for and if this is your need, then you should buy accordingly. Or buy a more traditional space heater with a blower to pair with this one.Let's talk about the "clicking" noise that so many of these reviews mention...The heater is extremely quiet, however, it does "click" as it cycles on and off maintaining temperature. How much of an issue this is will depend on you. I barely even notice this during the day when I'm awake and doing things. But I can see where this would be an annoyance for light sleepers. I tend to turn the heater off at night. If DeLonghi could do one thing to make this heater better it would be to eliminate the click.Once the room temp has risen to 70, the heater has no problem maintaining that on the low to medium setting. I've noticed that if the outside temp is mid 40's and above, it can maintain the room on it's lowest setting. But if the temp drops to the low 40's or 30's, then it needs medium. It's a little bit of a guess work because there are multiple power settings and multiple thermostat settings (0-6). I've got an external thermometer which really helps as there isn't one on this unit.The unit is mostly quiet as mentioned above, It's been odor free and works great. I would buy it again and recommend it as long as you understand what this heater will and won't do. Note that the heater works best in a single room and enclosed setting. If your room is open to other rooms, a hallway, etc., then you will probably be disappointed with this unit. It's not a multi room, whole house, open space, heater. Buy something else if that is your need.
December 14, 2015
I wish the cord was longer, and it might have been nice to have an attachable handle, because it's very awkward to move about. A lighted dial would have made it much easier to adjust at night too. It definitely does its job as a heater though, and hasn't driven up the electric bill like some models would have.
Its a good little heater
March 27, 2017
Way smaller than I expected but hey thats my own fault for not reading closer. Its a good little heater. Keeps the chill out of my garage.
Quiet heat source, small but not for large cold spaces.
January 14, 2017
This is well made and attractive. I like oil heat because it is quiet and consistent. At 700 W though it is not powerful but takes less energy and does not have to be on and off. It will take the chill off a bathroom (11 x 11 foot) that is insulated but not well heated from the main heat source (albeit gas forced air or radiant or whatever). I can keep the temperature at 65 degrees. I let the heater run on high for about 20 hours then was able to lower the setting. This is the use I bought it for so I think it was a good deal and good price. I gave 4 stars because people should realize that this is not for a big room or one that has little to no heat and/or no insulation. It will not replace a good heat source.
December 8, 2016
Works great for my bathroom, even when the main heat is off all while using less energy.
For the price, it's a great heater and provides warm radiating heat right where you want it.
January 20, 2016
If you work in a cold space this is the one! It fits perfectly under a desk even a chair. Warm radiated heat right by your legs. I have two pieces of negative feedback. If neither bothers you, give it a go. The price is certainly right!Two things I didn't care for: Where is the auto off? It would be great if you could set an auto off _option_ to turn the unit off after say 12 hours.Second thing is that the thermostat doesn't show numbers or degrees, so you have to adjust this not by a measurement, but by how warm you feel.On my nice to have list: Option to turn off after 10-12 hours. (End of a work day, or night in bed sleeping for instance.)Instaheat selection. A way to get ut heated up quickly when you turn it on. It takes a while to warm up.Still, for the price, it's a great heater and provides warm radiating heat right where you want it.
Compact space saver, good for small rooms.
November 6, 2015
We have two larger models from Honeywell and Lakewood from years ago, so I am familiar with oil filled radiator heaters. We keep the central gas heater practically off at night (55F) and use these to heat up occupied rooms to save energy. They are very quiet, save occasional thermostat clicks, and the warmth is ‘soft.’ Heat isn't as directional as other types of heaters, which I like. This compact heater works the same way, but there are a few differences, as described later.The product arrived packaged rather poorly, with the top Styrofoam piece all broken and missing a chunk. It still came in as one piece, but they really need some basic quality control.As another reviewer mentioned, the assembly instruction was useless. Actually, it was worse than useless since it tells you to use the non-existing U-bolt with a wing nut to attach the stand. The included rear stand is designed to work on its own without the elusive bolt. You just insert the last fin into the stand’s slot. I think the manual is just outdated.The heater is really light (9-10 lbs). No wheels unlike our larger models, but it’s so light that you really don’t need them. I just pick it up and move it around.Tested in two small rooms, each at about 100 - 120 sq ft, it worked well.· Both rooms are with one outside wall and single window, facing west. They are well insulated with no draft.· Outside temp was 40F· Indoor temp was at 66F, when the central heater was turned off. This radiator heater was turned on only then.· Both rooms maintained temp at 70F when the knob was turned to little less than half-way between low and high.Our larger heaters have two buttons: 600 W, 900 W, and both buttons can be turned on to get 1500 W total. They easily maintained 200+ sq ft room at 70F even when it’s cold outside (below 30) just with 600 W button pushed. In fact, we can’t remember ever using any other setting, which is why we picked this small heater with 700 W.The differences between this and the larger models I’ve noticed so far:- This mini heater gets hotter to touch, naturally because it contains less oil and the surface area to release heat is much less.- But while hot, it’s not hot enough to burn anyone as long as you don’t keep your hands on it for long. It’s uncomfortable enough to keep kids (and me) away from touching them barehanded. I had my little one touch it briefly to teach him not to play with it. The message got crossed without hurting him.- It’s about half high as the larger models, and narrower. I put it in my kid's room so in case it falls on them, it will hurt less due to lighter weight. (for safety I tucked it away between drawer and wall so it really can’t fall on him anyway, but this is another advantage of the non-directional radiator heater)I’d recommend this to those who need to heat up limited spaces and consider 70F to be comfortable temp. Not that I think it can only heat it up to 70F, but it all depends on the space and how well insulated.I can’t comment on its reliability as I haven’t used it long enough. It has seen only a few weeks of use so far but without any trouble. I’ve come across two reviews that said the switch stopped working prematurely. I am hoping they addressed that issue by now since it happened to the older model 6002 with 600W (this is model 6003 with 700W). The manual did not list any replacement part, so the switch may not be readily serviceable. (Personally, I’d just grab another switch and replace it if it breaks)

This works fine and I love it's size and compactness
April 4, 2016
This works fine and I love it's size and compactness. However, as other reviewers mentioned. This doesn't get smokin' hot. I keep it in my bedroom which is about 10x10 feet and it stays warm--but doesn't get super toasty with the door closed when it's really cold out. I have also used it under my desk which works well--keep feet warm. I wish someone made one slightly bigger and a bit warmer. It's also handy to dry things on--quickly--but wouldn't leave fabric on it unsupervised. It's hot to the touch.
Faulty had to return. (would of liked a simple exchange)
December 5, 2015
The space heater i recived was faulty .The caution light did not work, also something was lose in the electrics . It was not new, had finger prints all over it, plus you could tell that it had been opened and used before.I would of liked a simple exchange for one that was not faulty, but was not given that option. if i had If small children i would not buy this heater, i feel it could burn a small child. I was ok trying this heater on hardwood floors, but not sure how safe it would be on carpet. shame it was faulty, i would of liked to have kept it.
Cheap to run, but very limited utility
January 7, 2015
It's disappointing (and not only because it took Amazon three months to ship the unit), but it is still worth considering if you have a very specific need. It's only 400 watts, but that would be enough power to heat a small space if a reasonable amount of iron-rich metal were used in the body to retain and radiate heat. Instead, the body is constructed with paper-thin pot-metal panels. There's small amount of oil inside the unit that helps, but all told the thermal properties are poor. You can expect to heat about three cubic feet, and not much more.All that said, no one has produced a high-quality, cast-iron, low-wattage electric heater since the French stopped making them in 1960s, so you do not have much choice. Leaving a 1600-watt space heater on indefinitely will cost you at least $175 a month in electricity. This will cost you more like $45 -- like using ten 40-watt incandescent bulbs. It will gently heat the space under your desk. It can also warm a small bathroom, provided it is insulated and you leave the heater on continuously.

I bought this heater over a year ago for under my desk. It did a great job, but the little feet shattered after a couple of months. I ordered 2 more sets. This fall I started using it again. The feet shattered again, I should have taken note. But I really like this heater. Keeps my legs toasty in this old drafty house while I work. Two days ago, I noticed the housing for the electronics was open and I could see all the wiring. Under the heater was a bunch on pieces of plastic. The casing for the bolts holding the shell together had shattered. The heater was very hot and I just was lucky to have noticed. I keep this heater on a timer, so it is only on while I am working. I was almost tempted to get another one, but decided that the fire risk was too high. What if I had not noticed the open shell? I wonder how others are holding up?
November 28, 2011
I was hoping this heater would work for under a desk in our garage and we are in the mtns. It doesn't but inside the house under my desk it works fantastic. I just put it in my bathroom 12 x 15'ish since we don't have a heater in there and on the med setting it works great and was surprised. Very much a worth while purchase.
Nice and quiet, with caveats
December 31, 2010
We use these under our desks and they do a good job of warming without any noise. These units do get hot (about 250°F) so you need enough room that your toes won't touch the heater accidentally--ouch! The switch is fairly easy to operate with your toe and glows orange when it's on. But it's all too easy to forget to turn the heater off so it wastes energy. If they were smart, the heater would have a motion detector so it would turn off when you leave the desk. Only other complaint is the legs are too narrow so the heater is less stable than it should be. Still it does the job and it's nicer than a radiant heater with a fan for localized heating.Update 11/12:One of the plastic feet cracked in half. Fortunately, I contacted NewAir and they sent me to a web site where I could buy a replacement for $3.95. Still think the feet should be longer for greater stability, and more durable, but at least customer service was good.

weird unit. only getting 3 stars because it does in fact heat a room. literally 3% throttle on the thermostat is all that is needed for 72 degrees, and anything else is too high. plus every other heater in the world gives you the choice of 600 or 900 watts. small then large, like every other heater in existence. this one does 800 and 700, yes in backwards order, medium then another medium. why not give us a wattage choice, thats essentially the same wattage! what the heck? if i could go back in time i would have got the one in our other bedroom from walmart, but i was lazy and wanted it shipped to my door.
Two with dents in the same place
December 30, 2016
The product works quite well and meets my expectations. However, we ordered the product and it came dented. The box was not damaged, but it did look like it had been re-sealed. Amazon was very helpful, gave us a paid return label and sent us a new one. The new one had a dent in the same place. We decided to keep it and not go through the hassle of returning another one. I guess my expectation is to get a new unit that is not a factory second. It looked like both of these had been returned before.
Quickly heats the room but STRONG chemical odor up first use
November 27, 2016
Just set this unit up in our baby's room and although it quickly heated up the room to a toasty temperature... It also off-gassed significantly filling the room with a really strong chemical odor which left us all feeling nauseous. This is the last thing I wanted our baby breathing in!! I am sure it will wear off eventually... But the manufacturer should either 1) heat the unit up prior to shipping it to customers to get rid of the off-gas smell or 2) advise in the instruction manual to leave unit on full heat OUTSIDE for a few hours to get rid of the volatiles. I will be returning if the smell doesn't subside after a few more hours running on high outside. I also wish you could set to a certain temperature vs a 1-6 setting.
August 7, 2016
Have had this for a while now, really liked it at first, but for the price it's just ok. It's really no better than the cheap oil-filled radiators they sell at the home improvement stores for about half the price. The auto temp button is a gimmic that we really just don't use. Also, don't believe the line about "silent design." After about a month it started making ticking noises every time it kicks on- and the thermostats on these things turn them on and off every few minutes.. Most of the oil-filled heaters do that, but this one got loud. It's noisier than a cheap heater we bought at the home improvement store. If you like the idea of the little auto temp button, go ahead and get it. I'd rather just set the knob and pay less.
Heats well, but temp control is a joke
March 29, 2016
I purchased 2 of these to heat 2 bedrooms during winter allowing me to turn heat down really low during night to save some cash. While these both work and heat well, very quiet too. One of the main features of that made me buy was the temp control. I was hoping to set it to a temp and it would hold it. It just doesnt work, it always over heats the kids room, i have it set at 1 and using just low 700w setting it never shuts off and "maintains" temp like manual state, instead just keeps getting hotter, got room to 80 degrees. So I had to put it on a timer to controll on/off, just a total pain in the a$$ to have to adjust timer.
Nice and toasty
March 30, 2015
We use the DeLonghi to heat up our 300sq ft room and we don't even need to put it on high. It works quite well but the only annoying part is the clicking sound we hear when we turn on ComforTemp setting which automatically maintains the room to something around 70 degrees. Other reviewers probably have an explanation for this but we just end up not using it. Other than that, we like using radiant heaters since they tend not to dry out the air as much and the warmth from them seem to spread out better than a directional system. Also I feel a bit safer with a radiant heater than something with an open element.
good little heate for the $$
March 29, 2017
not a bad heater considering it's less the 2000 watts. no it's does'nt warm a whole 10 x 20 room or put off a mass of heat. however the cracking/popping sound many people have mentioned have not been nearly as loud as what i was afraid of and the price is right for a decent little heater for my rv! i can run it off my honda 1000 generator w/out blowing the breaker. i'll update review if it changes
Cuts the cold but doesnt really HEAT UP a room
December 12, 2016
It helps cut the cold from our small bedroom but I cannot say it warms the place. Great for the price in extremely desperate situations where the cold is unbearable, but dont expect it to really heat up the place!Its super small and portable, will be good to bring on a trip to a cabin or something where you might just need to take the cold edge off the air in a room.
if you have a SMALL area this could work nicely
December 6, 2016
My 3 stars might be unfair.... and this is why.... I am sure for a SMALL area this would work great.. but fo the area I needed it for.. it was not powerful enough... the area I wanted heated way 20 x 10 ft and there is a garage door so its not insulated.... but I could see this working in a 10 x 10 area and working pretty well... I was hoping it would work because its a nice handy little unit... easy to move and store for the summer... if you have a SMALL area this could work nicely
Love the degree
October 13, 2016
It is safe and dainty. Love the degree. Gave it 3 stars out of 5 because it doesn't radiate much heat. Not good for snowy days or cold weather condition. However, it's very safe. It self regulate and turns off on its own if it's overheated, which is up to 700 w, which is not much. It won't go any higher. You will probably buy it and return it because it feels like nothing. Even a toaster oven is hotter.
You won't be toasty
January 7, 2016
It's okay. Like most people say, if you're looking to really warm a room, this ain't gonna do it. It would be perfect for underneath a desk because it's really small. I wanted to use it to help my scuba gear dry in a hotel bathroom while on trips. But even in a small bathroom with the door closed, this heater did not really heat up the space. It warmed it, but it was far from toasty and things didn't really dry faster. Now we use it to make our bedroom "comfortable" on really cold winter nights. It's actually really good for that. If it's say in the teens or colder outside, you can crank this thing up and it will keep our bedroom at a comfortable sleeping temperature--not hot but not cold. Maybe mid-to-low 60s. But if you want it up in the 70s, it won't do that if it's super cold outside. Bottom line is that this heater is for under your desk or for slightly warming a small room or space. If you are looking for something that might, for example, make a bathroom toasty, you'll need a slightly more powerful unit.
Unable to dissipate it's full power without tripping the thermal safety
November 24, 2015
In summary, this unit is nearly what I wanted. But I wish they would have either made it slightly larger so it could actually dissipate 700 watts of power into a 62F room without over heating. Or they could have just put in a 450 watt (or whatever) element so it wouldn't get so hot, and then advertised accordingly.More detail:It's small, simple, and almost just what I was looking for. I use it in a small room I want to heat a little warmer without heating the whole house. I bought this to replace an 800 watt heater that had formerly done just fine. However, this heater rated at 700 watts just didn't do the job. Was 100 watts really that much of a difference? Curious, I put a meter on the line and realized this heater is actually drawing electricity (700 watts as rated) only a modest part of the time even when the thermostat is set to maximum. I soon noticed I could hear the "click" of the thermal safety, which is different than the click of the thermostat. The thermal safety kicks out when the fins reach about 90C halfway up (where the thermal safety is mounted inside the case). Then when cool enough the unit kicks back on again. Fine, safety is good. But the result is that the whole unit does not produce anywhere close to the heat one would expect from 700 watts since it cannot dissipate 700 watts into the air (62F) without overheating and temporarily shutting down.I wondered whether the thermal safety switch on mine is just defective, so I unscrewed the cover plate to examine the thermal safety. The thermal safety itself has a "90" on it (as well has 16A, 125V) which I take to mean 90C is its rated temp; certainly it kicks in at 90C. That's 194F which seems plenty hot to the touch anyway.I should note my unit is sitting fully open on all sides.So the unit works OK for modest heating, but it doesn't produce the heat it should for the 700 watts of draw it is rated and actually does pull-- when it's drawing current, and not cooling after overheating.

Um, don't bother with this one.
October 6, 2017
Unless you're sitting a foot away from this thing, in which case you'll probably knock it over, don't spend the money on this heater. It gets hot, but the heat doesn't go anywhere. I've been trying low-watt heaters because my apartment is freezing and it's all too easy to trip the breakers, which I don't have access to reset. So this one's a dud, but I'll keep it because I can put it on medium and hang my clothes over it for 1/2 hour before dressing so I have toasty clothes to put on. A bit expensive for that purpose, but sending it back is too much trouble.
Good for a few months of runtime.
December 30, 2016
Lasted 1 calendar year with no use from April through October. Thought it was a great little heater for that year but now it has leaked it's contents (oil) on to the rug. So I'm out $58 on this heater, ruined a rug, and possibly a pair of pants. Disappointing in the long run.
excellent heater, needs improvement.

Worked great for three years and six months
June 24, 2015
Worked great for three years and six months, then...design FAIL! The control panel split open while operating but sitting completely still. The unit is essentially two halves joined with plastic fittings held together with screws in the top right corner where the lifting ring is. Well, the plastic is very cheap and can't take the heat! This could be a safety hazard. Hopefully NewAir will address this in a future model, but STAY AWAY for safety/product quality reasons. I contacted NewAir by Facebook, but my post was not...posted.
not good Delonghi.
September 20, 2017
Plugged it in, did not work, took off the cover, found one of the 110 leads fallen off the connector,, checked all connectors and very loose, very dangerous, could of shorted out at later date ....not good Delonghi .....
Quality is uncertain. Don't let the people at the 800 number for support fool you.
January 24, 2017
Bought the unit and loved it, so a week later I bought a second one for a different part of the house. The second unit started "clicking" right away. I let it run for 4 hours thinking that the oil had to get hot. The clicking never stopped. The unit would be silent for 5 to 7 minutes then the clicking would come on. The next day, I called the 800 number for support, and they told me the clicking was normal operating procedure. I told them that my other, identical, unit had NEVER clicked. They again told me it was normal. Don't waste your time calling the 800 number. I felt like they just want to collect our names, phone numbers and email addresses. The unit is good, IF you get one that works, and don't let the people at the 800 number fool you into thinking that the unit's clicking is normal, because it's NOT.
It does not have a thermostat
November 29, 2016
We bought this heater to heat our baby nursery because it says it has a thermostat. I read reviews that said it was not a thermostat that you set the temp like it advertisers but you get it to the temp you want and then adjust the dial. That didn't even work. We would adjust it up and down all night ranging tempos anywhere from 65-79. If all you want to do is heat an area then this would work but if you need to maintain a fairly consistent temp this will not work.

November 28, 2015
It appears to heat fine. The problem with it is this incredibly noisy ticking it makes apparently related to the heating coil and the metal and oil expansion and contraction. I normally sleep with ear plugs in because I'm a light sleeper. They are rated for 32-33 Decibels. This heater wakes me up even with these ear plugs in. I have tried to tolerate it and move it to the other side of the room but it's intolerable. I will be looking into returning it.
I have several black delonghi heaters that work great! My house is large/ open floor plan
February 20, 2015
I have several black delonghi heaters that work great! My house is large/ open floor plan. However, this white heater does not work as well as my other heaters. I think it has something to do with the "coils" being thinner. I do not recommend this product!!!!! I would buy this one instead.... DeLonghi EW7507EB Oil Filled Radiator Heater Black 1500W. It works great for a large room with high ceilings. However, you may need several if you are using these to heat your home.
Leaks oil, heats well.
February 1, 2015
Never had much confidence in the safety of space heaters but I decided to give this one a try based on the good review. Had this one for 1 year to keep the chill out of our finished basement during the single digit winter days. Works fine, but just started leaking the inner oil, just about 1/2 oz, slow drip.
Hot to touch but nothing else gets warm.
August 31, 2017
I'm not exactly impressed. I have a small room in my basement about 12 ft x 6 ft and I need to keep it over 70 degrees year around. It has been in the 80s where I live and this barely keeps the temperature over 65 in this closed off SMALL room. I cringe at how inefficient this will be when the weather actually gets cold.
Inefficient, even for small spaces
May 12, 2017
I bought this as a downsize to the radiant heater I have for a treatment room in my office, approx 10'x12'. I use it to warm up the room a few degrees so I don't have to increase the central air for the entire office, and it can barely do it. It takes about six hours to bring the small room from 67 to 72 degrees Fahrenheit, instead of the 15 minutes my other one did with the same wattage. But it is quiet, with only the occasional click as it reaches temp. My old one with a timer clicked constantly and drove me nuts.
Does Not Heat 120 SQ Ft of Room.
March 17, 2017
My wife say this is cute but that is it. It advertises that it will heat 120 sq ft of room. That is not true I had in our bedroom which is exactly 120 sq ft. I left it on all day and all night until the next day and our bedroom is still cold. I do not recommend.
Decent Low-wattage Heater Except for Popping Noise
December 29, 2016
This heater is small but provides a decent amount of heat for only being 700 watts. We keep it in a bathroom that doesn't have a heating vent and the heater keeps it from getting uncomfortably cold in the winter.My biggest complaint is that it makes a loud popping sound every few minutes, which I think is the built in thermostat cycling power on and off. Don't buy this heater if you are planning to use it in a bedroom as you will never be able to sleep due to the noise.
Great unit for one year but performance is dropping
December 10, 2016
I bought mine last fall and it was FANTASTIC the first season. Perfect for my office. I even used it during the summer when the AC in the office was set too low for my liking. Now it's a little more than 12 months later and it isn't heating very well at all. The price point is great but I wish it had lasted longer. I need to look at getting something else now that winter has arrived.
Would be great, if it didn't leak oil.
February 14, 2016
We bought this heater in November for our mud room that doesn't have heat. When I pulled it out of the box, there were a couple drops of oil on one spot on the styrofoam packaging. My husband looked over the heater and said he couldn't see a leak. The heater worked great. About a month ago, I was cleaning the floor and under the front of the heater was a very small spot of oil. It's coming from the screw in the bottom front. Today, I cleaned the floor again and the oil spot was much bigger. So, the leak is getting worse. It is too late to return. As we only use a heater in this room during the winter months, the heater will last until spring. But, by next fall will probably lose too much oil to use safely. Very disappointed. Otherwise, it has been a great little heater.

Too hot for pets or children
March 28, 2017
Bought it as it stated was good to use with children and pets. NO WAY!! the top and sides stay cool to the touch but the back is super hot and can burn. There is even warnings in the instructions. You have to have it at least 3 feet from anything to use. We sent it back.
The bit of heat it does produce only comes off the top, not the sides
February 5, 2017
This is my first purchase of this brand item and it is by far the worst heater. It barely heats up at all even after 5 hours of constant running. The bit of heat it does produce only comes off the top, not the sides. I don't know if its defective or a straight up useless cheap product. I am so unhappy and disappointed.
Great Disposable Heater (Doesn't Last!)
January 24, 2017
This heater warmed the room spectacularly... for just over a year. Now the (small) room where I had kept it doesn't even get warmer. What a disappointment - especially because this happened between cold seasons, and in that time the warranty expired.I won't be buying a DeLonghi product ever again.
We have 2 tower heaters that were both less than this product and are better heaters in all situations
December 5, 2016
This thing heats a room very slowly and poorly. We have 2 tower heaters that were both less than this product and are better heaters in all situations. Save your money, it's not very good. This thing barely heated a 10 x 12 room. And by heated I mean made it slightly less cold.
November 1, 2016
Nonfunctional out of box. Did not turn on. Ordered two, one worked, one did not. The one that works is fine for a small room in mildly cool (50+) weather but does not work in a bigger room (20x20) or in very cold weather (<50) if the goal is to make the room habitable.
"CLANGS LOUDLY AND DOESN'T GET THAT HOT"
March 23, 2016
March of 2015 -PROS: It heats up right away, and will heat a small room.CONS: This heater began clinking and clanging right when we started using it. There is a "tink" that starts slow and then increases with frequency and volume all in a matter of ten seconds, then 7 minutes later, the tinking starts up again. It is really annoying when the heater is used in a particularly quiet room (like your bedroom.) Also, the heater doesn't get that hot?....I have a Black Honeywell Oil-Filled Radiator that gets much warmer and has stayed quiet for years.The last negative is that the Delonghi lets off this "new-heater" smell for the first day or so that smells like an attic. We had the window open right next to it, and it still took a while to clear.Main feedback: it "clangs" loudly and most importantly, IT DOESN'T GET THAT WARM!!!
I highly recommend that you spend an extra 15 dollars and buy a different product.
March 31, 2017
Product came in the retail packaging (not a shipping box). When I opened it, I realized that the product was damaged. The plastic material securing the front panel had broken during shipping (see photo). I read another review with this problem when I made the purchase, but I thought they were just unlucky... The heater still heats up, so continue reading for more info.I expected to use this heater in my office (an individual office about 10 ft by 10 ft) to subsidize the heating from the building when the temperature outside is between 45-65 degrees. My office has a window along one wall, and the window heaters don't turn on unless it's below 45 degrees (obviously the building heaters still do), making my office about 5 degrees colder than the rest of the building.So clearly, I wasn't expecting miracles of this little heater, I just wanted a 5 degree boost in temperature. This heater couldn't manage this. I've used these radiator type space heaters before, and I've been incredibly satisfied with them.I highly recommend that you spend an extra 15 dollars and buy a different product. This one came damaged due to poor packaging and couldn't even manage a 5 degree boost. If you plan to remain within 2 feet of the heater at all times then you might benefit from this, but you'd benefit so much more from a different unit.
As other reviewers have noted, this unit turns itself off on its own.
March 30, 2017
As other reviewers have noted, this unit turns itself off on its own. Works ok when its on, but you can't rely on it as a space heater for more than a day or so because it turns itslef off. This is true even the air temp never rises above about 50F. Some reviewers have thought an internal circuit breaker is triggered, but I don't think so. I think it is a preprogrammed feature, to stay on for 24 hours and then turn off.

Not even close to 700 Watts of heat!
May 27, 2016
Do NOT buy if you expect this to be anything close to your larger oil heater on its lowest setting, 600 watts in my case. Yes it does draw approximately 700 Watts when permitted as seen on a kill-o-watt meter, but it has an internal thermostat that shuts it OFF MUCH sooner than what you can set the external user-defined thermostat. To me the the external thermostat is kind of a "hoax" since it is a tactile moving mechanism device that is largely irrelevant. The thermostat knob is only relevant and useful from "zero" to about half way. After that it is the internal thermostat that constantly cycles and shuts the heater element off. (Of course if the heater was sitting in a room 50 degrees below zero and under a strong fan, it would probably always stay on all the time as ever consumer's past experience has proven.) If I had to guess I'd say it puts out LESS than half of 700 watts of heat (if not 1/3.). Why did't the manufacture simply make it as large as necessary to actually dissipate 700 Watts of heat as it is advertised as and does consume, or do the sufficient and quality testing necessary to see if in fact it is large enough already. Never before have I seen a heater sitting in a mild temperature room that cannot operate by design.
Stopped working after less than 3 months of use
January 13, 2016
I bought this October 21st 2015, January 13th 2016 it stopped working. I used it about 10 hours a day, most days of the week since about mid November. When working it provided suficient heat for its size, but i wouls not recommend this product, itshould still work!!!
This heater is so weak!!
December 11, 2015
I almost feel like I got a defective model or something! I had a standard sized portable oil heater from Walgreens which worked great, so I decided to give this one a try. First of all, it's about it's about 1/3 the size. I couldn't believe how small it was next to my old one. Second, it's also about 1/3 the heat output. I put it in a very small bedroom and it was barely noticeable. I suppose it's good for bathrooms, but the instruction manual specifically says NOT to use it in your bathroom! WHAT!? What is this heater meant for? It raises the temperature of a small room by about 4-6 degrees at Maximum settings--it barely takes the chill off. By comparison, my old oil heater gave a room about 6-8 degrees at its *lowest* setting. You can put your hand right next to this heater and the air is barely lukewarm. I don't understand the reviews about this heater being powerful--it gives off about the same heat as the outside of a toaster oven, and if it were any less powerful it would give off the same heat as a warm slice of bread.Also, mine had a rust spot on the side, and came in a dreadful looking taped up box. I think they sent me a used/defective unit even though I ordered new.
