    • Grat 400w heater
Positioned this next to a hydroponic grow box for winter temps inside the house. Works amazing fast heat and cool down as well as low energy use. Can program it with external technologies to maintain temps and cycle on and off. The plant has flourished in low household temps. Have had no problem with the plastic feet as others have mentioned but this may be due to my more regulated cycling to maintain constant. ... show more

    • Works well in a bathroom on those cold mornings!
My husband purchased this small heater for his bathroom. We had two clunky old metal oil based heaters that were worn out. I asked him to purchase one for my bathroom. It is simple to set up and heats up the bathroom perfectly. I love that it is smaller and easy to move and perfect for the small space it heats up. Extremely happy with this purchase. ... show more

    • I corrected its one obvious deficiency by MAKING MY OWN FEET.

Review Image by John W John W
So far, I think this heater has the potential to be a winning product — except for its one major flaw, noted by many other customers — the tendency for it to melt its plastic feet, fall over and be useless and potentially dangerous. I bought this product KNOWING about this serious flaw. Why? Because I needed a heater to put into a compact space (under a porch to keep pipes from freezing), and after a LOT of looking, I couldn't find ANY small space heater on Amazon that didn't have reviews of people warning, "This is dangerous, and may burn your house down!" The selling points on this heater were its enclosed oil-filled nature, and the fact that out of 1,187 reviews (as of January 2025), I only noted one review that said, "This heater exploded." All of the other reviews were of people warning that it would melt its factory-supplied plastic feet. Well, that was a fixable problem. So I ordered the heater. Once it arrived, I put the plastic feet on and fired it up. I wanted to see whether I felt it was necessary to make my own. And after a little bit, it got hot enough that I thought, "Yeah, I'd better do this." The bracket was a spare piece I had in the garage, that I cut into four sections. I attached two pieces per foot with a screw and some washers, including a lock washer. Then I cut a couple of feet from a spare 1x4 and screwed it on. Done! I made the feet wider, and I used as much of the bracket as I had available. The piece I started with was 13", and it cut nicely into four 3 inch sections. Having some extra metal down there helps dissipate the heat before it gets to the wood. It's still hot — when it really heats up, on the hotter bracket I have to remove my hand after a few seconds — but it shouldn't get hot enough to cause any kind of fire concern. Even so, I'm going to provide a smoke detector in the room, and a fire extinguisher. It's cheap insurance in a situation where, realistically, it's not going to be monitored all the time and will most kick on at night. Now, just as long as it doesn't develop an oil leak (which is a problem a few other customers have noted), we should be good to go. ... show more

    • I thought this one is easy because not complicated
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 ... show more

    • Very happy with this little heater!
I was nervous about purchasing this heater after reading the reviews. Here's what I've learned after taking a chance. 1) To attach the feet, press them in the MIDDLE, not on the sides. And be gentle. I had zero issues. 2) No tripping the circuit breaker at 400 watts! 3) Based on the Min/Max setting you set the heater to, it will heat up, then cut off, then cut on again at regular intervals. This means you get the heat level you want but also that the unit won't overheat (though, if that happens, it has an auto cut-off). When it cycles off, you'll hear a click. Same thing when it cuts back on—just like with an HVAC wall thermostat. 4) The cord is longer than expected, which is great because it means I didn't need an extension cord. But if you DO need one, the product booklet that comes in the packaging specifies which rating of extension cord to use. 5) While the heater is in operation, there is no noise at all. 6) Even at a little above "Min," it puts out a decent amount of heat, so if you're using it in a small space, you'll be fine. I don't expect this heater to last forever, but I registered it anyway. If there's ever an issue, the company looks to stand behind it. ... show more
