Hot air out the side
Hi I was just wondering if the hot exhaust from the furnace was just wasted heat or is it just stale exhaust? It sure seems to be a lot of heat coming out of there!

When we were going with an RV furnace my thoughts were to vent it through a VW oil cooler radiator... Running through a very small pump feeding into another oil cooler on the inside with computer fan. With the little bat usage I think some of the heat could be recovered??
