Great little radiant heater

L. A. Pounders, PhDDecember 24, 2025

UPDATE 12/29: Yay, received a new unit that works! And it’s just what I was looking for. It heats the small space of my van using much less energy and without the overheating that my other fan-type ceramic heater does. Radiant heat rocks! The thermostat means that the heater turns on and off, and this uses less electricity overall—which also means I will be able to use it with my Bluetti portable battery. Bottom line, although the first one was defective, it was an easy return and reorder through Amazon, and I am very satisfied with the heater (including the feet). ORIGINAL: Just received and plugged in and no heat. The on light comes on but no heating happens. Tried the “reset button” but cannot tell if anything happens. The dial is turned to max. Will call customer service and perhaps try ordering another to see if this one is just faulty. Disappointed ☹️ AFTER CUSTOMER SERVICE CALL = raised one-star Customer service was quick and very friendly. Ultimately they said that I must have a "defective" unit. I am returning this one and have ordered another. Will update review once that heater is in hand. Read more

Perfect

S.S.C.January 6, 2014

I wanted something slim to keep in my upstairs bathroom and something that did not draw alot of power. This unit is quite slim and 400 watts max. There's a dial so I guess if you turned it halfway you'd be using 200 watts approx. Heats up quickly and silently and quite does the job in my 7x5 bathroom. You are not supposed to get it wet- it says on the box don't use it in the bathroom. But use some common sense and don't splash it, don't keep it too close to the sink, and turn it off n move it away from the shower before showering. It makes no noise at all while it is warming up or maintaining heat. The only noises it makes are when you turn it off. Then it makes some decently loud clicks every couple of minutes for about 10 or 15 minutes. No big deal. Would be nice if there was another handle on it so you could pick it up with two hands to move it. Some have complained about the legs not being sturdy. I had a little bit of difficulty getting the legs to snap on as they should, but did triumph in the end, and it is quite sturdy. Would recommend for other small rooms or as a personal heater... next to bed, next to couch, etc. Very nice, very happy with purchase. UPDATE 2/8/2018. Still working well for my bathroom. Helps out a lot before getting in the shower in the morning, as I turn the heat down to 68 at night. My bathroom, and the rest of my upstairs is like 60 degrees on a cold morning (upstairs 60, downstairs 68- bad insulation I guess) and this little heater does a great job of quickly getting my bathroom close to 70 by the time I get in the shower. Also, tho I don't take HOT showers, this heater also keeps the mirror from fogging up, and I lay my semi-wet towel across it when I finish drying off (turning off the heater and not covering the vent.) Does a nice job too of warming my socks up when I get home from work. Update: 10/22/14...... I have recommended this heater to a few people. It's a shame there are a few bad reviews here JUST due to some of the heater's feet. Some older models had plastic feet and this caused issues with breaking legs and instability. Mine are metal, and have caused me no issues whatsoever- never had to re-adjust the feet. If you are on the fence about buying it, don't be. Update 1/13/2016......Ordered another one for my drafty kitchen for mealtime. Checked the feet on both units- I am pretty sure they ARE plastic! Magnets slide right off. My apologies to those I may have offended. Sounds and feels like metal when you tap it. Very strong though, and I have had zero issues with it. I guess a few people got duds. Read more

I thought this one is easy because not complicated

Imogene Louise ReidJanuary 31, 2018

I plunged it in, but it simply would not turn on. I thought this one is easy because not complicated. Book said can reset it with an insulated stick. I am 77 years young & I have no tools, so where is the stick? It did show where to reset it, so I may could have done that. I am A slammed into my car, so I currently have no transportation. NO NEED to tell me where to take it. It has to work when I get it (NEW). Also, I only ordered it one time & I Do NOT WANT another one. UPS came yesterday 1-31-18 picked up the last of the 3 headers I really wanted the TRN0812 DeLonghi Heater. 6 deliveries for 1 heater does not make good business sense,especially since when I still do not have one that works . I think I am getting returns instead of new ones. Reason for ordering is the $150.00 electric bill. That is high for old conservative me. I now have moved into one room with the only heater that works, the DeLonghi EW7707CM with the Comfort temperature (gray). I love the color. Works great so far. I would still like to have the T R N 0812T if I could get off the reject list & better instructions on the timer. I have A large area where 3 rooms are open. I believe these 2 heaters would keep them warmer & cut that electric bill at least 20%. I had a 2 story home in another town where I had a large open space in the middle of the house. I had oil heaters in 3 bedrooms, ceiling fans in every room, 3 solar panels on the roof for the hot water,,2,200square ft. My electric bill was usually only $110.00 per month. (Also a fireplace). The electric Co. had to come out & see why my bill was so low, when my neighbors bill was $400.00 or more with almost same size house. IMOGENE Read more

The best heater ever, worth the investment.

Russell LawsonOctober 13, 2025

Great heater, I keep this between my legs hanging from my desk during the winter and it heats my arteries really well, keeping me warm. my only gripe about it is that there are only two settings on it, it has a turn dial but there are only two heat settings within that dial, and if it had one more between those two setting it would be perfect, otherwise it's either too cold or too hot.

Great Under Desk Heater

John R. ConnollyDecember 13, 2025

This is a phenomenal under-desk heater. Silent, gentle warmth, simple thermostat, low to no risk of burning, doesn't take much space. Can't recommend highly enough for that use. Read more

Happy & warm.

Margaret McCainDecember 2, 2025

This thing is awesome. Small & keeps my studio apartment from getting below 60*F most nights. I also feel like it is safe for my animals. Very happy with this product. Used to keep it in my bathroom, and it made it soooo toasty in there! Read more
