Who would know at what temperature a coal fire burns? And what temperature would you expect inside the firebox above the hot coals?
Inquiring minds need to know!

And if I am correct, the stack temp is usually lower than the stove top temp meaning that my stack temp probobly is about 50 to 100 degrees lower. This is more than enough to warm my 1800 SF home. I would be really curious to see what your stove top temp is. The magnetic thermometers are about $10.

My gf's parents have an old (and cold) cottage with a large iron fireplace (grate?) in the living room which seems to cost them a fortune to run over the winter but they have no other heating source in that room. Anyway, my plan is to make them a heat exchanger / manifold to sit under the coals connected to a blower of some description to make the most of it but I worry the temps could melt the stainless steel tubing I plan to use and start spitting out molten metal!
Am I worrying over nothing?
