heat always travels from hot to cold , what I don't understand is where your fire gets oxygen with the doors closed.
Mine gets oxygen from the outside via a flexible duct through the wall.
With the doors open I'm burning inside air and have heat loss up the chimney. With doors closed , I'm burning outside air and getting radiant heat through the doors - hot to cold.
