What options would I have to make this area more climate controlled? I don't have enough breaker positions left to install a 220v anything out there. Is it feasible to bring a duct from the crawl space through the bottom plates and get a vent in the room? There is a 6" wall between the porch and den. Would that provide enough air? Would a return vent be required?
Any suggestions appreciated.
I sure a good heating man can put a couple of runs into that room up through the plates. Keep in mind if you want to pump air into a room that you have to let the air get out so it can be run through the heating plant again. Can you run a jumper duct in the attic to let the return air out. As soon as the hot air starts pumping in it will pressurize the room and push the air out the jumper
duct. As to how much heat you need out there and if your heating system can handle the extra load is a engineering thing. Paul
