Question: Is it safe to put the heater on the carpet (the floor)? Thank you! Is there any safety issue?
Document: In the morning we turn it off. Our twins do like to play with it and turn it on because it makes a beeping noise when turned on and as it cycles through the different temperatures. The safety switch on the bottom works just like it should. If the twins knock the heater over it automatically turns off. We used to worry that if we had it on the floor it could scorch or burn the carpet but now we know that to be an unfounded worry.
It only heats a small/medium bedroom-sized room. It is quiet (not silent, but very quiet), which is really important to me. I like the safety feature that it turns off when tipped. It's hot to the touch, but wouldn't instantly burn you, so I feel it's pretty safe around my kids.My main complaint is that the temperature settings never really worked for us. We have much better luck just putting it on "high" or "low".
We have had this same heater since 2005 and it is still working great! Just wanted to have a 2nd one for our other bathroom. Thank you for still offering this same model!
great little heater, really helps keep you warm and safe, love the temperature control, only wish it had a more forceful blower for the heater, other than that, it is quiet, warm, and does shut off when it reaches the desired temperature.
Holmes HCH4953-U Ultra Quiet Dual Ceramic Heater with 1Touch Electronic ThermostatThis space heater works GREAT and it was super cheep! Love it! Very easy to use and very safe!
I've used this heater continuously for the past 4 Montana winters and it still works great. The fan is still whisper quiet and pumps out a ton of heat. The only long-term flaw I've encountered is that the color changing paint on the front is orange all the time now, even when the heater is ice cold, but that is really a minor issue.
This heater is awesome! It is so quiet and keeps my office very warm. Very easy to use and compact enough to put under the desk.
At first it looked like the heater plug had arc-welded itself to the extension cord. But instead it melted everything inside the extension cord outlet. Thank gooness it was the only thing on that extension cord and the only thing plugged into that wall socket. We thought after prying it loose from (and destroying)  the extension cord that the heater was fine since its plug looked normal.
Really good, really simple, really quite.Heats up the room fast .Thank you - whoever designed it!
The sides don't get hot at all, but if it tipped over on carpet or something I could see this being a potential fire hazard. So satisfied with every other aspect of this heater we are keeping, and probably getting a 2nd for the other bedroom. Arrived super fast too! ** Update**  Our furnace went out for two days in January in Nebraska (brrrrrrr) and we had a true test of this heater!
Answer: I keep it on a tile floor. I think there would be safety issues in putting it on carpet. It is small and could tip over.
