I'm building the stand/plenum for a downdraft hot air mobile home furnace to sit on. Frame is angle iron, 24x18, 18" high cube. Sides will be covered with bolt-on sheet metal panels. Bottom will sit on an uninsulated concrete slab.
My question is, should I insulate between the bottom of the frame and the slab? I can see the slab being a giant heat sink and sucking up a lot of the heat for no good purpose.
I'm thinking a piece of 2" blue board, some half inch spacers and a sheet metal floor in the frame.
Yes? No? Won't make any difference?
