I have an ice box in Texas and a RHP alone was not enough in my pvc cages. Didn't work in my 4ft x 2ft x 18in or my 2ft x 2ft x 18in cage.

The large ones are fairly thin pvc so I wasn't to surprised but the cube is much thicker pvc and I was surprised it wasn't heated better. It was an easy fix as I added a oil heater to the room and now they are all good.

A RHP is not great in thinner walled cages and they are not great for long or tall cages. However in thick wood cages they do seem to perform well and are probably the best choice for a cage made out of it.
