Pretty much as long as the sun is shining, there is heat. Matter of fact, right now its 47 degrees outside, I have the door wide open, the chilly wind is blowing in and the temp. in there is 79. If the door was shut, it would be a furnace.

I have had the door open since about 9 AM, when it was about 29-30 degrees.

And I only use single layer right now.
