You might check out the infrared heaters. No hot surfaces, and will heat your house really well, and hardly any draw on electricity! My neighbors in Montana have them. I am going to get some for my house, when I get back out there. I didn't get any before I left, and wish I had. My electric bill went up, with the wall heaters going all the time to keep the temp above freezing. I have the fan on, and so far the temps. only been around 40 or so, inside the house. I had winterized the house, and shop before I left. But check out those infrared heaters. I think Sportsmans guide sells them also.

I know several people that swear by these little heaters, it might be worth your time to look at them. I don't know but I have heard that the more elements it has the better and more efficient it heats. I would check that out before making my decision on one of these heaters
