I see that it states that it'll heat a room using the least amount of energy, but that seems ambiguous. Is it cheap to run?

Honestly mine is only used for maybe 20-25 minutes a day warming our Master bath, which runs colder than rest of house, while my wife takes a shower and dries off. I don't see any appreciable rise in electric bill in winter and my wife is very happy with how much it heats the room. It is a fairly large bathroom roughly 9 x 16' and seems to warm up pretty good. I doubt if I answered your question but we are pretty happy with ours.

Low but should not be expected to warm a room on it's own. Great for ambiance but an oil filled heater is the more cost effective option.

I agree with the others. My Phenom 9850BE processor noticeably warms my room up under heavy load as it is. I expect that this one at 220 watts would definitely affect your heating/cooling expenses. Nothin' gives ya the WARM fuzzies like a fast multicore processor! :-)

It does not affect the electric bill that I have noticed, I don't run it all the time only for short periods as it warms up the room (9x12) quickly.

it would run quite a bit and like the other answer depends on other factors. they are not cost effective when running all the time. if it is a one room closed off it probably will work for you

It only heats a very small space like a 150 sq ft room. I would not use it for sole source heat. We use ours to supplement a natural gas furnace and move it around to areas we are in during the day. It has a built in thermostat which turns the unit off and on. I would not recommend having it running if you are not present.

You can think of this as an air conditioner followed by a heater, so i theory it cools then heats to the same temperature. The reality is anything that is electrical will create some heat, but this unit doesn't significantly add to the heat of any room it is intended for. Keep in mind that this is a very robust unit, intended for a basement, or multi room area with good air flow between the rooms. You wouldn't want to use it in a small bedroom.

Because there may be many times when you don't need 10,000 W to do the job. Whenever the 10,000 W heater is running that's what it is using. If 5000 W will take the chill out you're using half the energy.

Don't buy this expecting it to be energy efficient. It will run your electric bill up. I am total electric and I use it on "flames only" most of the time for ambiance as it will easily increase your elec bill $20 to $30 a month if you use it often.

When we got ours, I ran it constantly and never noticed a spike in the energy bill. Depending on your friends situation, they may find that if they are running it with the cold setting it is cooling off the house then causing the heat to run, or if they are running it on the warm setting it could cause the house to warm up causing the AC to run more. I'd suggest keeping it away from the thermostat and running cold in the summer & warm in the winter.

It comes on instantly and puts out a good amount of heat but will not heat a large area. It is good for a small room and would be good in a camper. It has no blower or fan so I guess you call it radiant heat. It has swing low, low, off, high, swing high and it will not work if it is not sitting straight on the floor as it has a safety button on the bottom so if it falls it cuts off.

I cannot say it is energy efficient ??? but keeps the den habitable to enjoy and can lower the main furnace (electric heat) so not entire heater has to run as often.

Yes. I used it in my bedroom.. It heated up my 200sq bedroom in about an hour and costed me just over 1 dollar a night...

I use mine to keep a relatively Uninsulated mudroom at a decent temperature and with it on low. Just make sure you have it on its own power supply and not a power strip. It's a powerful little thing.

Not sure. It should heat a 20' x 20' room very well. You also can take it off "Auto" and it will run all the time and not try to get to its set temp. If the air coming off the machine while it is running isn't hot, then your unit is defective.

I'm not sure, I know it is cheap to run, cheaper then the furnace i think it is 8 cents or so an hour. I havent had to turn my heat on since I bought this last year before winter. I love it.

It is definitely the most cost efficient space heater I've ever used. It is cheaper to run than the traditional electric space heaters.
