6″ Castle Stair Build

Dragon Rocket Masonry Heater, stair build

Stair build with oven prior to “skinning”

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″x20″ 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 1400 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 240-300F.

Next, we will finish the oven and add a decorative finish to the flues.

    Please post pictures of the finished oven!
    Thanks!

    • Based on testing we have redesigned the door and they are in production. We will post pics as soon as we have them. We decided to reduce the size of the glass, to keep more heat in, and place a notch on the mounting plate for the 12V light, and change the hinge side.
