Shawn, from the numbers you are showing here, the outside of the oven is around 300 F at the point when you refire. And it goes up to around 450 F.

I live in PA, and the following idea might not apply to Arizona, but it certainly would have applied to Vermont. The idea is that if I was going to build an oven like that, and the outside was going to be 350 to 450 F, I would try to design a way to capture that heat and pump it back into my house. Maybe a sheet metal box surrounding the oven with a fan on a thermostat. Maybe use it to preheat the water headed into my hot water tank. Maybe run a small steam turbine that can run a generator and charge batteries to run my lights. One would need to do some serious engineering, maybe consult some mechanical and electrical engineers, but you could save a bundle in utility costs, even pay for the oven in a few years.

You got me thinking here.
