Will this work ? Heating a large enclosure

[JibbaJabba]

Sounds like a lot of work for a ball python?

Everyone I know that has large enclosures and ball pythons have large enclosures with NON eating ball python.
Your idea sounds do-able, but at what cost and will the snake like it?

I guess I just try to make it work as the viv wasn't cheap

The surface area isn't really large (3ft) but it is quite high (2ft) ...
