It gets cold in my old home unless your in my sons room where his snake is. I heat up the room with a space heater and I also have a heat emitter above the area of the warm side. I use Eco-earth and a wet towel to keep the humidity up to around 50% , if you use the brick eco like me do not put a towel ove the top for awhile as even after you get out most of the water the humidity is already at 50% for a couple of days as the top is dry but you can see the moisture underneath.
