Question: Will this heat my small, drafty apartment?  The apartment is 424 square feet with a 7-foot ceiling.  Thanks.
Document: Hubby and I live in a 1200 square foot apartment which has a central gas heating system. I bought three of these heaters because of the high cost of heating but mostly, the noise of the central heat becomes very irritating after several months. It's so noisy that when we watch tv in the evening, we have to turn it up and down when the heater goes on and off.I love this heater. I turned it for the first time this evening...warmth and quiet...perrrrrrrrrfect!
Not as good as I had hoped: you have to be within 3 feet of the output to feel any heat. In a very small space (less than 150 square feet) this unit works well. However, anything larger and you will only be warmed directly in front of the vent.The vent system is also poorly constructed: at its most horizontal setting, hot air is blowing into your face; at its most vertical--the warmth is going into outer space.
Heating has become very important to my well-being as late since this is my first winter in a 120 year Victorian home with no heating, no insulation, and poor sealing. My bedroom is about 200 square feet with ten foot ceilings, wood floor, two large windows, and three doors that allow cold air to seep in.
This heater truely does heat the room. Our living room is about 400 square feet and this heater works quite well. It is very quiet and heats up in a matter of seconds from the point that you turn it on. You can have it directly up against a wall because it doesn't pull air from the back, it pulls it from under the heater. It also has an ionizer which is a pretty neat feature. You can change the direction in which the heat is blowing and change the speed as well.
That's right; we are using this as the sole heat source in our rented duplex (about 700-800 square feet) which has no central heat, no gas, no wood-burning stove and mediocre insulation. However, caveat that we do live in South Central Texas, so ice and freezing weather is about the extent of our "winter worries." I doubt using it like this would be as feasible of an option up north.
This is a fantastic little heater for the bucks. It is very quiet, puts out a lot of heat. I run it on auto and this feature is awesome for a heater in this price range. I have it placed aprox. 10 feet from my bed and cannot hear it operating at all on the low fan setting, barely hear it on the high setting. I have been thru a few small heaters and this one is by far the best. I would buy another if I needed one more.
The area that it is heating is about 1500 square feet. I love this heater
I don't have to disrupt my roommates by heating the whole house in the morning. I also bought the lower end without remote (the 758000) which uses the same heater core and it heats my 450 square foot office. It is a corner office with a sliding door to a balcony, and a wall of windows.I do want to add some cons to this review:- No tip over detection, as others mentioned.
If you live somewhere where you regularly see 20 below zero, then your heating needs may be far more demanding than mine.The unit heats my 13' x 12.5' (8 foot ceiling) bedroom very well. (It will make the room uncomfortably hot if I want. )My biggest complaint about this unit is that the temperature sensor does not seem to work very well. The unit does not shut off until the room is too hot, and it doesn't turn on again until the room is too cold.
I live in a 1 bedroom apartment with the heating vents in a bad place due to my furnitue. I have put this in a location were it can bacically cover the 900 sq feet. I have notice I pay no more on my electric payments for using this, matter of fact I pay less. I love the remote, as I set the temp I want and let it go. very happy with this.
Answer: Mine is 16 by 24, 3 windows and patio door, I use the heavy duty curtain designer ($ 25 at Walmart) style double sided material that slides between family room and kitchen. This really helps keep the heat inside this room. The heater actually displays and measures the floor temperature which is lower than your sitting temperature. When it displays 67 degrees it is really warm. I have 10 foot vaulted ceiling. The ionizer really is great also. No unusual smells either. Clean heat. For the price it is great so far. Warms the room quickly and very quiet with varying flow angle adjustment.
