Or you could heat your room. My snake room is heated every winter to 75 degrees with an oil heater. I don't really worry about it in the summer, some days it's hot enough in there everything is basically shut off. If heating your room in the winter isn't an option, or would be a fire hazard, then two sets of heat tape would be fine. That's what I recommend for people that want to use tanks, but have a cold house. One side set at 78-80 degrees, one side set at 88-90 degrees.
