My fireplace is in my big family room in my new addition. It is a Quadrafire 7100. whats the best way to get the heat circulated to the old part of the house.I have a fan blowing into the old part of the house but doesnt seem to me moving much heat to it.I have ceiling fans in the new addition which keeps the heat in there moving but just cant seem to get the heat through the doorway to the other part of the house.
