I'm not 100% certain but pretty sure that ceramic heat emitters can be mounted horizontally. However, you won't get near as good of a hot spot as you would by mounting them vertically. A 10ft snake basking with horizontal CHEs could have several degrees temperature difference from one side to the other (furthest away from CHE).
Below is a photo of the CHE guards I made for my cages.
Later!
