If it were a python or a boa I would use a ceramic heat emitter and a UTH. I don't like the FW and I've not dealt with RHP. I'm wanting a 32x23x20 enclosure so I can put my two rufous beaked snakes in there. They are a Diurnal snake so I use a bulb to heat slightly, but mainly for light and at night I turn on the moonlight bulb as I call it which I run both on a dimmer so I dim it so it gives off a faint blow glow to mimic the moon. The temps in the room are well regulated so I don't need to use anything else, though I may add an UTH eventually. I've had a Rufous Beaked Snake before and he was the happiest camper in a 10 gallon with the same setup. That's why I'm set on having the two holes for light fixtures.
