Using heat dump to dry firewood?
It occurred to me as I was driving back home yesterday, would it make sense with a non drainback solar heating setup that has excess collector during the summer, to harness the excess heat to dry firewood? I am visualizing a bay window like structure with the firewood stacked on horizontal CI radiators, fresh air vents on the bottom, and a whirly ball exhaust on the roof. I don't have a huge heatsink like a swimming pool and this would be doing productive work instead of just collecting the heat and then reradiating it.
With a PV DC powered circulator, I don't think I would be too concerned about power outages.
