For heating (which is also how I heat my corn snake enclosures): UTH under tank on 1 side plugged into a thermostat. A CHE (also plugged into a thermostat) on the other side of the tank keeping the ambient temperature up. Our house gets pretty cool at night.
Definitely open to other suggestions?
-- also, can I get a recommendation on what my temperatures should be for the warm side and the cool side?
