Furnace Surface Area - Scrub Buds
I'm toying with the idea of pushing copper scrub buds between the furnace baffels to increase the surface area of heat transfer. I'm trying to make a better heat exchanger out of it. I'm thinking that the scrub buds will also reduce the airflow between the baffels which could be counter productive or helpful? Has anyone attempted to improve the efficiency of the furnace.
My heat bump is about 60-65 F through the furnace and the exhaust air outside is about 320F. Isn't there a way to capture some of the wasted BTU's?
