Thanks for the advice and pictures.
It looks lovely.

I'd be worried about the belly heat maintaining temperature son its own especially during the winter so the CHE looks like a good bet. I note that you can order from AP with a circular mesh cut out on the top as you have. What equipment are you using with the CHE and I assume it is also connected to a tstat - the same one? if not where have you put the probe.

Great set up by the way - sorry for the20 qs.
Have emailed AP.
