The setup you're talking about is exactly what I have for one of my terrariums and it works great. I have an AP T12 with a RHP (60 watt) and heat tape underneath the hide. Even though the room I keep the terrarium in gets a little cold (about mid 60s) in the winter, the cool side of the AP stays in mid 70s. The RHP does a good job at keeping the ambient temps are.

If your house gets a lot colder, I'd suggest getting a long RHP so most of the cage gets heated. I know the RHPs are a little bit expensive but in my opinion they're definitely worth it.
