![]() A couple of days ago, I stuck a thermometer up in my attic. Nothing fancy, just a wired unit that shows temperature. As its getting cooler, I'm finding the house cooling off slowly. I'd love to be able to get a bit more heat without having to turn on the furnace. So, last night I came home to find my attic at 92F (33C) at around 5pm and decided I was going to use some of that heat. I stuck a box fan into the attic access door and blew it down. Here is the very simple and quick setup.
Now, I'm not sure how much heat I really got out of it. The immediate area was definitely warm, but the room you see in the picture has a thermometer in the far corner and that didn't register any heat gain. However, when I went to sleep roughly 3.5 hours later the attic was still pretty warm as shown below. So, it looks like the heat definitely has to be better distributed. I need a way to get it down to the first floor first. My first idea is to use the cutoff chimney in the attic! Its currently uncapped and probably making me loose a fair amount of heat in winter. I just haven't gotten around to putting some insulation around it yet. ![]() To get it down to the first floor, I was thinking of using this vent hole that I had previously plugged up with foam. Its in my kitchen which is normally the coldest room in my house. Having some extra heat in there would be great. ![]() So, I'm just kind of throwing out the idea to see what people think and get some suggestions. To get much heat I'd probably need a fair size blower/fan I'd imagine. I'm also not sure how long this will be useful? Will it be completely useless in winter? I guess we'll just have to see. I also did a quick search on builditsolar and found this: Attic based solar heting attic temp logged data These show that its not an original idea by far, and the temperature log of the attic I guess suggests that winter use really doesn't seem very viable. However, different climates and different types of construction will alter temperatures. So, I guess I'll wait and see.
