Dragon Heaters bring modern physics and materials to Rocket Heater design concepts. Dragon Heaters replace the Rocket Mass Heater cob bench with a series of masonry style bells located under the combustion chamber. Like the Rocket Mass Heater it releases ½ of the heat via a radiating barrel, and the other ½ is dumped into the bells. These bells can be filled with locally available stone, clay, or firebrick (recommended) to provide the thermal mass. They can provide up to 10+ hours of radiating heat after the fire is out without requiring extra floor space, or complicated construction techniques. They can also match any esthetic décor and be moved like a traditional wood stove.
