Circulating heat in cathedral ceiling to bedroom in basement
For clients, I have built an addition on a 1960 A-Frame (Vermont, zone-6) which includes a basement master bedroom and main floor dining room and mudroom. The existing house has a forced air heating system and wood stove. The later is the primary heat source. The cathedral space of the A-Frame collects a significant amount of heat. The addition is reasonably well air sealed and insulated, R35 walls, but the existing is a wild-card. Currently, the kitchen has an exhaust only range hood and the bathrooms rely on window opening and have no other ventilation. Could I expect an ERV with a stale air exhaust placed in the cathedral space to transfer enough of the available heat to the basement master bedroom fresh air supply?
