They are in my garage and I cant have them anywhere else.
You could try insulating it with a blanket wrapped around part of the top and sides, just make sure it's safe you know. If you can't insulate the heat enough, you'll probably have to pick up another heat mat, preferably the internal one I was talking about putting it inside or wrapping it around the outside.
