My BRB is in a pvc cage that's 4ft x 2ft x 18in. He has a uth and a rhp. I found that the rhp does not heat the entire cage properly without creating a hot spot that is to warm for him. I now have all my snakes in one room and heat the room with a oil filler heater. I still run the uth and rhp for a warm spot but hardly ever uses it. His favorite place is his pool or under the newspaper. I don't even put hides in there any more.

The rhp can work just fine for a BRB but the issue can be if the rhp and cage you have will work properly in your home. The one good think about a BRB is they do not require as warm of temps as many so it may be a bit easier for you to get set up.
