We can't tell if ours are broken or not because it's our first time experiencing what could just be shortcomings. I've got the heat on at 80 today and can lay my hand on the heater and not get burned, but can feel that there is some heat coming out. Should I be able to do that? I have no point of reference! I don't want to waste an electricians time (or our money) if we just have a drafty house. But I'm freaking freezing and working from home with frozen fingers is not the jam. Help!
