A friend of mine who keeps one ball python has a wife who likes to be ***cold*** so their house never gets higher than 70*F in the summer, and 66-68*F is typical in the winter. He uses two large UTH's on thermostats for his snake. One UTH is set to 92*F, the other to 82*F, with a heavy ceramic/rock hide over each UTH. The UTH's don't raise the ambient in the enclosure but they do heat up the air under the hides, and since the hides are made of heavy material they do retain heat fairly well.
A CHE or DHP would also work to increase the overall ambient temp but they tend to dry out the enclosure, so you'd be constantly fighting to retain humidity.
