Air runs 24/7. House is still hot. 4600 sq ft attic. If I buy 2-20 watt would it help cool house or just attic? Do I loose heat in winter?

I installed one in a 1500 sq ft attic and it did cool our house. I did some temperature measurements before and after and estimated it cooled our house in summer by 5 degrees. I also purchased the add on thermostat, so the fan is never on in winter as the attic never reaches a warm enough temperature for it to switch on.

Yes it will help to cool your house because it pull out the heat off the attic. In winter it will pull off the cool of the attic which means that helps to keep the house hooter because there is no cool coming down from your attic. Hope this will help you in your desition.

Mine has never worked. I don't know if the installation was done correctly as I haven't been able to get on the roof to look.

What it does is, it pulls in the air from the outside through the vents along the eaves around the house. By doing that it forces the hot air out through the attic fan. It drops the attic temperature so there won't be much heat seeping through the ceilings into the resident level of the house. When the attic is really hot, the heat gets to the resident level and then the ac will also have to cool that. It's a constant battle for the ac system. I have noticed my summer electric bill dropped by half or more.

Our home is 1400 square feet and it's just right. I think the larger unit would be too much. This one could probably go up to 1500. We have 4 of the 1/2 round roof vents and 2 of the ~12x16 dormer vents - that's more than enough to vent the air out the roof. You'll also notice secondary cooling because the attic get's aired-out. The noise isn't bad - of course that's subjective. Anyway, we have no central air and when it cools off outside at night, the fan cools the whole house very quickly. During moderate days, it keeps a freshing breeze throughout.

So much of the ability to keep an area warm depends on the height, insulation, air leaks, and surface area exposed to external temperatures that you can't predict heating performance by square footage alone. Check the temperature of the air next to the heater. If it's cold, the heater is at fault, if it's hot you've got other problems.

yes, my 200 watt is running about 6 F too high and my 300 watt is running about 11 F too high...however they do seem to hold steady once you compensate. And I do seem to have to recheck/recalibrate for the summer months. however there are so few heaters available with an exterior control i figured i'll just put up with this until something better comes along.

This is a VERY good heater. I am using it a 400 square foot garage it heats very well regardless of the temperature outside very efficiently . That said I know it will heat the area that you will be using it in. However the fan that is on this heater does not produce a large air flow. It is basically designed to move the heat away from the heater with very little air flow. What I would recommend is to buy a few small floor fans to move the air throughout the cabin. I am not sure there is a heater on the market that would provide enough air flow to provide the cabin with uniform heat

Fan strength is good. If you get about 3 or 4 feet away you don't feel much heat. But I live in Vermont and I use 2 of these to heat my 1100 square foot house and it has been well below zero for a few weeks and they keep up pretty well.

This model dimplex at 2000 watts will give you 6824 btus. You ca. Heat a small bedroom 60sqft with 8ft ceilings with no problem. The insulation and the windows will effect this greatly if you have drafts.

Absolutely YES. YES. Highest heat transfer comes with coldest air MOVING against the hottest surface. Also, using a fan will cause the heater to draw (slightly) more power, making (slightly) more heat and spreading it widely. (Lower temp-&gt;lower element resistance-&gt;higher power draw-&gt;greater heat output with no bad effect on the life-span of the heater, it's a win-win.) AND, the fan will ensure that the thermostat never switches the heater OFF. Every extra minute ON is another minute generating more heat. :) Another fan, on the floor, blowing colder floor-air up and into the warmer ceiling-air (hot air rises) will mix the air, making the room more comfortable in less time. Fans are NOT just for summer anymore, because they can help you stay warm, too. :) Did anyone here take college physics? FYI- I was an engineer for thirty years or so. Hope this is useful. PS-I have a fan running now, in New England, in November, on a gray and blustery day.

Assuming the attic is insulated pretty well & no taller than 8 ft., I would estimate each unit is good for about 300 sq. ft. Think in terms of the amount of heat coming off a 100 watt light bulb. It isn't hot but does provide a small steady source of heat. If you lose heat from a draft or uninsulated windows, then you will need more units. For the amount of space you have, I would look for an option that has a fan. 2,000 sq ft with an 8 ft. ceiling is 16,000 cubic feet to heat. That sounds unrealistic for a passive unit that relies on natural convection.

Place it in a central location that would be convenient to heat the whole house but away from thermostat. Order the blower attachment and keep the doors on rooms not in use open only a little ways. My stove heats an area that is 1456 sq. ft. and I very rarely run my furnace even in the winter time. The winter in West Pa was terribly cold last year.

Ours, ceiling mounted, runs quite warm. I second the recommendation to use standoffs to increase airflow around the unit. I suspect that will help it last longer.

depends on the size of the attic. If you have a vent at one and, and exhaust air with this fan at the other end, a normal size attic should cool significantly. Even better, and intake fan at one and an exhaust at the other!

It does require a fresh air intake as well as an exhaust. Attic air will likely be far too warm for heat exchange purposes.

If your air handler is in the attic, it will be significant. If it's mounted in the garage, not as much. The further south you live, the higher the savings. Stick with this unit as the power draw is minimal compared to the larger unit which draws twice as much power.

This heater works best in a closed off room versus trying to heat an entire house. I use mine in master (20x20) bedroom over top garage. It has no problem keeping the room around 72 degrees. The thermostat on unit is off by 5 degrees for some reason.

I would not use this in a attic. It will not move enough air and is not set for temp

Definitely ! I use one just like this in my small livingroom that has a wood floor, and on the 800 watt setting it keeps me warm and comfortable even when the temperatures drop down in the 20's. It will keep the temperature at about 66 to 67 degrees which is just fine for me :) It beats the high electricity bills I get if I were to use the walls heaters my home came with ! Just make sure you set it out in the open so it can work properly, and not right up close to you ! If I need a little extra up close heat I just use my heated electric throw/blanket. When your on a fixed income, this heater will take care of you ! Definitely !
