I recently moved to Southern Maryland and want to install a furnace to assist with my electric heat. The recent temperatures in the area have forces my system to run on emergency heat. The house has a wood stove in the garage, but doesn't seem to produce a lot of heat. I had a load of firewood delivered by a friend of the previous homeowner who suggested that I look into installing a wood furnace. The electric heat system in located in the crawl space under the house, so that isn't helping the situation. Would I be wasting money in the form of firewood and efficiency of the furnace by installing it in the garage. I could remove the stove and use the existing chimney for the furnace. I would only need to tie the duct from the wood furnace into the existing ductwork. Any suggestions would be greatly appreciated. I need to check some local shops to check on installation costs.
