Custom Acrylic GTP Tank

[raycam01_au]

Hi Guy's
I am just about to start work on a custom 900x900x450mm GTP Acrylic tank for a friend, just wanting some ideas on the heating side of it, I have over 19 years making fishtanks etc, and have made a few timber enclosures for reptiles, so pretty handy in that regard.
So what im asking for is some ideas, on how to best heat the tank, be it 1 heat source or more.
let me know open to all suggestions.

I make all my own enclosures and in my greens I prefer to use a heat radiator and a dual thermo with a reptiglo 2 for lighting
