This 6″ Dragon heater is in a small 2 floor apartment, so space is at a premium. This build uses a tall single bell (8 ft) lined with fire brick. Larger 20″ x 20″ flues were used to maximize heat capture and allow for the oven. The excess heat from the bell is radiated from the stove pipe as it exits through the ceiling. It takes a hour and half for the heat to start radiating, but it will then raise the room temperature of this 1,400 square ft apartment about 1 degree an hour.

Fire Bricks lining Dragon Heater Stair Build

Fire bricks

The firebrick stores more heat and does it faster than clay flues. However, each brick must be cut and laid. So it takes more time and expense than the inner clay flue liner approach used with the other Castle Build. The larger flues used on this build are also necessary for sufficient clearance around the oven. Even without a door on the oven yet, the temps stay 240-300°F.
