will it heat a large uninsalated room with 17 windows?

to some point, how cold does it get out side? I had it in a room 12x24 and it ran all the time and never got above 0 c, it was -20 outside

it will definately take the chill out of the air, but since it is uninsalated and has 17 windows that probablly leak air, you will probably need two. If the room was insulated it would keep it warm

Not very good for this type of application. It is better for a room that is well insulated. 16 X 23 may be too much area in a basement for this type of heater.

it depends on how well your room is insulated.the thing is basically an oversized, high power heat lamp.

I'm not sure if it will heat up that size room but I want to warn you that the two Vornado heaters I have purchased in the past were pieces of unreliable junk. I ended up spending more money for DR. HEATER (2 of them) and they both work great after over two years of usage - please avoid Vornado if you can.

This will most definitely heat a room this size. It will simply shut down when the room is at temp so no worries about overkill. We are heating a 400 sq foot space easily.

We installed one unit to cover an entire church building. Since the whole place is heated by one boiler we just picked the room with the lowest temperature. If you have separate heating systems involved, I don't see why you can't use more than one.

it definitely depends on several factors including climate, ceiling height, amount of insulation in ceiling and walls, and how well the Windows are sealed. This will be our first winter with this particular unit, but I expect it to heat our dining room and living room. I think it is more a question of how many rooms can it heat since it only has one output location compared to central heating. It is more than adequate for any reasonably sized room in a house but will have a challenge heating the whole house.

it will cool 500 sq ft. saying the temp outside is over 95 degrees. 1000 sq ft is way too much for any window type that is 110v

Yes. I have a 2600 square ft hm. It heats the whole house..as a back up. Even upstairs.

In heat pump mode (above 45), it produces as much heat as 2 space heaters. So if you need 3+ space heaters on high to heat that room (like if you have bad insulation), no. If it only takes 1, this will work even faster/better.

It heats up well, but I use it mostly for instant heat rather than heating up the room, since it is a fan forced type. I guess, if you're going to use it for the main heater, about 10X15 would be the maximum you can get, without other heating source.

It will cool up to a 400sq. ft. room, which is not at all very big. This unit is horrible and do not make the mistake of buying it. It simply does not cool.

since it's only a 400/800 watt heater, it's more of a spot heater. Since your room is 15x20, you should look into a more powerful heater that puts out 1500 watts in one of its settings. I actually don't use the oscillating feature because it's not that powerful and usually use the 800 setting for just a couple of hours. Overnight, I switch it to the 400 watt setting.I think those Living Pure infrared heaters would heat up your 15x20 room easily and those heaters radiate the heat everywhere whereas this heater is more of a directional, spot heater

it has 2 settings, 400 watts and 800 watts. It won't heat your 15x20 room...it's more of a spot heater at the 800 watt setting. If you want something that can easily heat up with those dimensions, I would go for a Living Pure heater that puts out 1500 watts and which radiates the heat in all directions I don't even use the oscillating feature because then the heat dispersion is uneven

Yes, I have this heater in my living room and kitchen, which are about that size. The two rooms are divided by a wall with a window and door way in it. One heater does a good job of heating both rooms, we rarely turn both on

it will, but it will be a lot hotter near the unit than the other end of the room

Way to many variables for an accurate answer, so will say no it won't. It is a "radiant" heater, it heats stuff, not air. Some heat out the top, but not much. What it will do... At sunset, grab a couple of quilts and throw on the couch. Set this thing 3 or 4 feet out in front and fire it up. Shortly, everybody will be bundled up with their feet out pointed towards it. Warm and toastie toes. Your 4 legged critters will take over the floor under your feet. Watch a movie, pass around pop corn, or maybe, HOLY CRAP, take turns reading to the little ones.
