Enclosure Question: Height vs Depth

[Bogertophis]

I was planning on a RHP as it seemed the most efficient way to heat the cage, so I suppose that does make sense. Would there be any way to help a RHP along heating up the bottom of a 24" if I go that route? I am leaning towards the T20 now but you do make a good point about heating, so I want to make sure I pick the best one I can.

As already suggested, adding a UTH would be the option I'd choose to make sure the 'floor' wasn't too chilly. Either enclosure will work, each has pro's & con's.
