Dragon Heaters are available now for your spring/summer construction project.

We have 3 sizes: 4", 6", and 8" cores done according to Peter van den Berg's design as he outlined starting on page 111 of the 3rd edition of rocket mass heaters. The cores are made from an insulative cast refractory and have a 20 year expected life when properly cured. The combustion system also includes a steel feed tube which keeps the opening of the burn tunnel cool and a heat riser made from vermiculite (or similar) board. The heat riser is assembled by the user with 316 stainless steel screws.

Our barrel build for the 4" and 6" can be constructed in a half day using inexpensive materials. There is a video of this build. You can take the output from this build and run it through a bench.

If you would prefer not to have a steel drum in your house, we have designs and kits for constructing a mass heater which uses stratifying chambers called bells rather than a flue for absorbing the heat from the exhaust. You can still have a bench after a bell, if desired.

The kits include specialty refractory items in the proper sizes not easily obtainable otherwise. Instructions for constructing the kits are provided in PDF's upon purchase.

Testing data on our builds and information essays on why we made the design choices we did are found on our blog. All the details and prices for our offerings are on our website.
