De'Longhi Oil filled Radiator Heater, 1500W Electric Space Heater for indoor use, portable room heater, Energy Saving, full room like office and bedroom with safety features, EW7707CM

I bought this for my mom and she really likes it. It’s a very good quality and it radiates heat because it’s oil filled and it doesn’t dry out the room as much as regular electric heaters It rolls and it’s a decent size so you can keep it out-of-the-way when you’re not using it

I was looking for a quiet, efficient heater to use in my sons bedroom at night. His bedroom is on the end of the house and usually 3 or 4 degrees cooler than the rest of the house. This heater did the trick. After reading numerous reviews I had mixed feelings on this. I basically bought it because the price was low enough that if it didn't work, I wasn't out a ton of cash. I'll just say I'm very pleased so far! Pros: Size - When I initially think radiator, I picture the giant iron ones from the old days. This is nice and compact and fits in nicely in the corner of the room Noise - other than a little click when the "thermostat" goes on or off, there's no noise Heat - gives off a nice, moist, calm heat. When I say moist and calm I'm comparing this to other electric heating elements that get red hot and use a a fan that tends to dry out a room in a hurry. This heater emits a nice gentle heat. Efficiency - You set the dial to the desired setting. The unit will heat to that point, then shut down, however it continues to residually heat the room without using any power. When it gets below a certain desired setting, it clicks back on to reheat itself. Cons The instructions could explain how to use the temp dial and comfort-temp a little better. In addition, I'd like to attempt to clarify the "thermostat" issue. Reqading the reviews here confused me a bit as to what to expect. First off, there technically IS a thermostat....just not like the one you're probably used to. Theres a dial with numeric settings on it, not a temperature range like you would expect. It takes a bit of trial and error to get it where you like, but it's not terrible. 1. There are 2 on/off switches. Right(low), left (medium), both (high). I can only explain these as the speed of how to get your unit to the desired temp. If you're not in a hurry, use low. If you want it to heat up faster, use medium, if you want it to temp as fast as possible, use both switches. Once the unit is to temperature, I only use the low setting to maintain a constant temp. This method seems most efficient. 2. Using any of the 3 settings above, turn on the unit and start the dial at 1. 3. After about an hour use a thermometer to note the room temp. (I use a cheap digital one I got from Walmart). If the temperature is what you desire, 1 is your setting. If not, go to #4 4. Turn the dial to 2 (or in between 1 and 2 if you have the time) and repeat step 3 5. Once your room is at the desired temp, thats your setting. I found that in order to keep my sons room at 72 degrees during the cold Chicago nights, I use setting 4. I cycle it back to in between 3 and 4 for when he naps during the day and the outside temp is a bit warmer. I'm very pleased with the accuracy as well. I leave the digital thermometer in his room 24/7. I randomly check it before I go to bed after he's sleeping and in the morning when he gets up. 9 out of 10 times it's right at 72 with the occasional 71 or 73. As for the comfortemp, I cant attest. I dont use it. It was so easy to find my temp range I didn't even bother with it. I also didn't experience and bad odors. Maybe it's because Im only using the lower settings and not cranking it up to heat a big room, but it went from the box to my sons room without having to melt off any coatings or things to that matter. I highly recommend this if you need a quiet,gradual, efficient source of heat.

After reading many of the reviews on Amazon, I purchased this delonghi heater. I can't be happier with its performance. I believe the more positive reviews are a result of using this heater as it was designed - to gradually maintain a slow heat in a small-mid sized enclosed room (say, 20x20 with 9' ceilings). If you want to quickly heat a large room with a blast of hot air, get something with a fan or turn up the thermostat. We use this heater at night. It does such an effective job of keeping our room at a comfortable 70F (even at lower settings), that we have programmed our central heat thermostat to go down to 60F at night. Of course, the effectiveness of the heater is also dependent on how well your house is insulated. There were some comments about the heater getting hot to the touch. Well, yes, of course it does - it's a heater! But even at it's highest setting, the metal is not sizzling. It is well insulated enough that you can touch it for a few seconds before it gets uncomfortable - plenty of time for the occasional times you may bump into it. At lower settings - this isn't even an issue. Why an oil-filled heater? It produces a very gentle heat without drying the air like a conventional ceramic or electric heater. Why the delonghi? Gentle heat without any sound. We purchased the Honeywell 7-Fin Oil-Filled Radiator Heater as well (they were out of stock of the delonghi), and while it heats fine, it creaks and cracks when you use it. I'm sure this is due to the metal expanding and contracting as it gets warmer and cooler. It's not a huge problem, but if you are a light sleeper, it may be an annoyance. The only downside I can think of is the wheels. Doesn't roll well on carpet - which is fine, we don't' move it much anyway. But overall, love the delonghi. We've had it for 2 weeks now and I hope it lasts this way for several years.

As temperatures dropped toward freezing in southern Florida this year, we purchased two of these heaters. I opted for these oil filled heaters over the well-rated ceramic heaters due to concerns over drying the air out too much (some of the ceramic reviewers noted this as a drawback). In the end, while perhaps less than ceramic, the wife and kids seem to feel these dry out the air too. Not a lot, but noticeable. Both heaters arrived quickly and undamaged, but we quickly determined that one of the heaters had a rhythmic clicking about every hour or so. After having the clicking dance wake me up about every hour throughout the night, I called the manufacturer. They said the clicking was not normal and that the unit was defective, and this is where I really like Amazon. I boxed the unit back up, visited the Amazon website, selected UPS pickup right at my door, and two days later the defective unit was on its way back to Amazon with barely any effort on my end and at no cost to me. Simultaneously with the return, I opted for Amazon to send me a replacement unit, which arrived within about three days. No double charge to my credit card since Amazon had my old unit within the allotted 30 days. As for the units themselves, they work great and are very quiet (just a single very subtle thermostatic "click" every now and again when the unit triggers for heat). My father-in-law bought a fan heater from Lowe's a few days before I got these, but took it back because it was too noisy. My wife told him we ordered oil filled heaters from Amazon and they were quiet. He came down to look at what we got, and ordered his own from Amazon. The units emit more than enough heat to keep any of our individual bedrooms warm, even with the bedroom door left open. I left my daughter's room closed for a couple hours to warm it up before bedtime, and when we opened the door, it was way too toasty (her room is about 12x12 with an adjoining bathroom that is probably about 7x7). The unit certainly helps larger areas, but don't expect it to heat a 25x25 area up to normal room temperature when outside temps are 30s or 40s. Having said that, I was happily surprised that our 25x25 living room space never got below 65 with just one of these heaters running in a corner. So it will certainly keep any room livable and comfortable. I gave the unit four stars, but admittedly not giving it five stars was difficult. It is a compact unit sold at a very reasonable cost. It is easy to set up and operate. It is quiet and will keep you warm (but be patient, because it takes a little while to get things warmed up). I didn't give it five stars because, while it is constructed well enough, it's certainly not built bullet proof. The other reason is the unit's very singular and limited role (i.e. it doesn't have options that might make it more versatile). But it's precisely these demerits that undoubtedly provide for the reasonable price, hence my five star dilemma.

I bought three of these for our home because this type of heater was the only space heater the insurance company would let us buy for the office where I worked. I felt these De'Longhi Oil Filled Radiator Heaters were the safest ones for our home as well. They have worked very well for us and still work well for warmth in far rooms years after I bought them here. We also have an earlier De'Longhi one, of a little different design, that I bought over 20 years ago that is still going strong and it is the reason I stuck with this particular brand name.

This is a pre-assembled well designed and steady efficient heater. Measures 16" wide but manufacturer reccommendations require 3 feet of clear space in front of it and above it. The smell of toasted oil dissipates after a day of use set on LOW, the manual reccommends 2 hours on HIGH to achieve this burnoff. It has a two pronged polarized plug rather than a grounded plug, so easier to use. The power drawn is 120V - 60Hz -1500w and yes it is made in China. Shipping is the only real complaint I have and thats Amazon not the manufacturer. I got two, and each time it was poorly packed into the large Amazon box. Rattling around packed only with a piece of paper!!!! Luckily, the manufacturer's box holding the heater is packed very well with form fitting shock absorbing styro, but I'm sure it suffered knocks on the trip--the large Amazon shipping box arrived at our loading dock both times looking like it had been opened or crushed and our receiving manager was not impressed. A complaint slip was sent back each time to notify them.. It would be much improved if they just packed it with those bags of air instead a thin piece of paper. After all, being oil filled you would think Amazon would precautions to avoid springing a leak and baggies of air weigh next to nothing. The first has worked fine for two days, the second one did have its styrofoam block break apart from a knock apparently, but the heater was undented and has been on for a full night with no complaints. Still.... You actually need only use it on low or medium, as it heats steadily and warms a 60 degree room in 10-20 minutes to a comfortable temp. After being plugged in and set on LOW, the plug and cord dont even get slightly warm which suprised me. The DeLonghi get slightly warm after an hour when the heater is set to MEDIUM, however, which is normal according to the manufacturer in the manual. Overnight while on MEDIUM setting it warms an entire large room and event akes the edge off of adjoining rooms like hallway and kitchen. This is just enough for someone who has asthma to breathe easier without being bothered by the cold air or wasting energy. Still havent seen my energy bill yet so we'll see. We liked it so much after I got the first one, we bought a second one. We keep each heater on a separate circuit and no higher than medium setting and we wont blow a fuse! The thermostat is efficient and accurate and it has a thermostat version of cruise control as well. Very nice. The thermo cruise control has a large dial and light which is bright enough to serve as a night light.

BE AWARE -- IF YOU PLAN TO USE AS A LAST-RESORT HEATING SOURCE TO PROTECT YOUR PIPES!! I wanted to buy a bunch of heaters to place around my home in key areas in winter, in case the main heating were to go out -- these would kick-in (in "Anti-Freeze" mode) at 44 degrees, and hopefully keep the house safely above freezing (at least). So (foolish me) I bought 9 of these, instead of getting one first and testing it... Anyway, the first one I tested in AntiFreeze mode would not come on at all in a 32 degree room -- just sat there stone (ice) cold. So while I assumed the unit was defective, I called DeLonghi tech support before returning it to Amazon (a card in the box tells you to do so). DeLonghi agreed that the unit was defective, so I returned it. Today I opened the second unit, and it was a little better than the first, but not much. In a 36 degree room, it occasionally came on (about once a half hour), the coils heated only VERY briefly (a minute or two), the unit never got hot, and quickly cooled right back down until the next cycle (a half hour later). Most of the time it sat there stone (ice) cold. So I called DeLonghi again, and they seemed to imply that this unit is working as designed. I explained that, per my expectations (and requirements), if my house gets down to 36 degrees, I need this puppy to come alive and go full blast until we get the temp back up to close to 44. But, they explained to me, that I shouldn't expect that. According to them, this heater will only produce very small amounts of heat in AntiFreeze mode -- I should NOT expect it to get good and hot and do some really useful heating. I told them that the product description doesn't say that we shouldn't expect the unit to get hot in AntiFreeze mode, and they didn't argue (BTW they were ALWAYS very friendly and tried to be helpful). But the walk-away was clearly that I shouldn't expect this heater to jump in when the temp drops below 44 and do any serious heating (which is exactly what I need it to do). So I had to send them all back. Needless to say, Amazon was great, and processed the returns no problem. The problem lies with the website description (which was presumably authored by DeLonghi).

This is a very good quality heater. The big advantage of the De Longhi is it's great thermostat that keeps the room at a constant temperature. This might seem obvious, but cheaper heaters often do not do this well. When I use my other, cheaper, heater -- a Pelonis oil-filled heater Model NY1507-15K1 (also sold on Amazon) the temperature in the room can vary by as much as 5°F. The De Longhi with it's more accurate thermostat keeps the room at a constant temperature. The build quality of the De Longhi is also noticeably better than the Pelonis. The De Longhi thermostat is also absolutely silent, which cannot be said for the Pelonis. I still don't know what the DeLonghi's ComforTemp button is for, and the manual really doesn't explain it well. I suspect it's just a marketing gizmo. I think when the ComfortTemp button is depressed the heater decides on what it thinks is a comfortable temperature and over-rides any thermostat settings you may have set. I find this a dubious feature -- how does a heater know what temperature is "best" for my room? So I don't use it. De Longhi's advertising says the ComforTemp is an energy saving feature, but that is bogus. It cannot be. The laws of thermodynamics are not violated by the ComforTemp button -- it takes the same amount of energy to heat your room to a constant temperature no matter what the settings are on the heater. I should deduct a star for that deceptive marketing, but I'm reviewing the heater, not De Longhi. A nice feature are the fold-out wheels. No screws or assembly required. But honestly, you fold the wheels out once and its done, lol. But it is nice to not have to hunt for a screwdriver. I'm very happy with this heater. It is as powerful as any 1500W heater can be, it is well made, it controls the temperature very well around a set point, it is silent, and it is far from the most expensive oil-filled heater out there. A very good buy at $64.30.
