Had a couple places come out to quote me on adding heat to my basement.....23'x17' finished area.
The quotes were fine and all, but no one mentioned possibly making this part a 3rd zone (already have 2 zones in my house). We have a 3 ton setup. I asked specifically about zoning it, their reasoning was "too much air for such a small space". Can you make a dump zone and dump the extra air somewhere?
Which leads me to ask........is the unfinshed side of the basement (where the furnace and water heater are located) an acceptable "dump zone"? Wasnt sure if you could (by code, or even by common sense) dump conditioned air back into where the equipment is.
Firing the furnace completely just for the basement would seem wasteful, but we are down there so little that it wouldnt bother me to do so. The heat would only be on when we are down there, and even then it wouldnt be very high (basically a little extra heat to take the edge off). I was originally thinking an electric baseboard setup, but I found some abandoned ductwork over the basement that would be perfect for a supply, and all that would need to be added is a return.
