Has anyone with a basement install opened up their cold air returns in the stove room and used the furnace blower to heat the upstairs? One of our ruturn ducts is about 10 ft from the stove and while the fire was cruising, the area around the duct was 85degress tonight. I am thinking if I open up this duct and just run the furnace fan, it sould pull the heat thru the duct work and maybee heat the upstairs better. Then I think I can still use the whole house humidifier on the furnace to humidify the house still, since the air will pass it as it heats upstairs.Will this work?. Anyone try this?
