What's the best way to go about heating a JCP enclosure? I've read about people using a UTH, but other people recommend a Radiant Heat Panel, because they're semi aboreal and others say UTH and CHE combo...

It seems a lot more complicated than a BP, but I'm hoping some of you experienced JCP owners will have some ideas...

The cage is 600mmX500mmX600mm (LXBXH).
