I have a wood burning stove in my living room and it often produces way more heat than I need for the room, so Im wondering if I can use some duct work, a fan, and an AC thermostat to spread the heat around my house and reduce my furnace running times. There are no existing registers in the room as it is an addition to an old house, so I'm thinking of taking the duct work through the attic the length of the house and then down to the basement to create a circulation of air. Can I put a duct fan in an attic? Will it be too noisey? Will it be cost effective to do? The house is about 60ft long, so probably 76ft of duct work would be needed.
