I also live in a very cold house. I have my BP in an exo terra glass tank, with a uth set at 96 degrees, which keeps the hot side at 90 to 92 degrees. I use a twin deep dome holder for a red heat bulb and a plain white light for daytime, as his corner is pretty dark. I can adjust the hight of the lamp so the ambient temp stays at around 80 to 85. To manage humidity in the winter I have moss under his hot hide, around some of the bottom of the tank, and i use a reptifogger to add humidity. I also cover the front holes and half his screen cover. hope this helps.
