If you have an existing ductwork system in your home, you may be able to hook a wood furnace up to it. However, there are a few things you need to take into account before doing so. First, check with your local building code office to see if there are any restrictions or requirements for installing a wood furnace in your area. Second, make sure the size and BTU output of the wood furnace is compatible with your ductwork system. Third, have a professional contractor or HVAC technician install the wood furnace to ensure it is done correctly and safely.
