will it heat 400 sq. ft. room?

My guess is "yes". We use it in our 38 foot 5th wheel, which is 304 square feet with the slides in, so a little more than that with the slides out.

yes it works great,,,set timer to come on 1 hr before we get up and the room is nice and warm for us....

No. I tried to use it in a 12 x 20 room and it didn't generate enough heat for the room. It only made noise. I could feel the heat right next to it. It can possibly be used ubder your desk to warm up your feet. I stored mine in the attic. What a waste.

No too small get a 6in fan and filter you need Atleast 400cfm for that square footage

Nope. It's only 400 Watts, and even with the temp reading 71 degrees, I held my palm on the flat surface for a minute with no discomfort. I would NOT allow kids or pets close to it, and I'd be sure to keep the space in front and around it clear of any paper, fabric, anything flammable. It gives off a gentle, warm heat, and is not intended to be the sole source of heat.

Heats my entire room without any additional heat source. Room is approximately 800 sq ft.

The heater works great. The room we have it in is about 300 square feet. It heats that room nicely and then some.

4600 BTU 250 sqft heating area, I'm assuming this is with everything set a maximum

Yes, I would absolutely recommend Mr. Heater. We have a 400 sq ft living room in a drafty, old house. We didn't have to turn it up higher than the first setting and the whole living room was warm and comfortable. Just make sure it is well ventilated.

I'm not well-versed on BTU's and watts comparison. I can, however, support the answer by Randolph Eck. I agree that this heater does not adequately or quickly heat 800 sq ft. It would be an okay heater for a small bedroom or bathroom, if you don't mind the beeping when you push the buttons. But, I would suggest buying a smaller space heater in the $30 to $60 range instead of this one, if price is a factor.

Yes the room will heat up. The electricity used will creat heat for the room. Turn on your air conditioner to remove the heat.

Not sure... but the beauty of this machine is its timer: set and forget it! Your space will be as warm as you want it as long as your ceilings aren't higher than the standard 8 feet. Hope that helps!

We have not used ours in a large space, but imagine it would work fine in a 100 square foot space. Not sure about 500 though.

Exactly, I am not sure; but it heats a 300 sq ft room on my house very well.

Same square footage as yours. This heater puts out only a mild heat that will dissipate quickly in bigger rooms, with possibly large or multiple windows. The smaller the space the better it works. It struggled to keep up a satisfactory temp in a space the size of ours. High ceilings probably didn't help my situation either. I placed mine in a bit smaller room and it works wonderfully.

This unit will heat a 500 sq ft area as long as the area is well insulated even the roofing.

Regret that i cannot answer that question. We live in a 26,000 sq foot school house with no central heat. We use a woodburner in the kitchen and use our fabulous Dr. Infrared Heater in the library which is 1250 square foot. We operate it all day,everyday and I have it on one temperature and have not changed it so far because it keeps this room livable. Maybe you could call the manufacturer. I do not know what the situation is for other people using this product but know it has been so helpful to us with this really cold winter this year.

Not sure about the square feet, but I suggest you look at alternative heating units, they will undoubtedly provide you with heat. This unit is not worth the expense.

I'm not sure. We have ours in a bathroom, perhaps 9x9, and it takes a VERY short amount of time to heat it!
