Scandinavian HWAM fires have a heat sensitive spring that auto regulates the amount of air going into the combustion chamber of the fire, so that you continually get optimised buring of the wood:
- More heat from the same amount of wood
- Less ash
- Less hassle
- Less soot on the glass.

Fire Heat Storage / Thermal Store
Create a thermal mass, with the chimney around the fire, so that post the fire dying out heat is slowly released into the room.
