Workshop Description:

Learn how to make your own high efficiency wood heating device for your own home!

A Rocket Mass Heater (RMH) is a super-efficient wood-fired heating system composed of two parts: Part One is a rocket stove, consisting of a feed tube, burn tunnel and heat riser; Part Two is the mass chimney, through which hot exhaust gases from the rocket stove are ducted into a thermal heat storage made of masonry materials like cob, stone, urbanite or brick.  All of the heat that goes up the chimney with a conventional wood stove is saved and stored in a Rocket Mass Heater.  The heated up Mass can radiate heat for up to 48hrs or longer after the fire is out. A RMH can also incorporate a cooking surface and an oven, and can be finished to become a beautiful centrepiece in a home.


Unlike open tube rocket stoves, a RMH can have a sealed combustion chamber and allow users to stoke a firebox with a long burn time. This make a RMH much more appropriate for heating homes and other spaces where open combustion is not desirable.

In this workshop, you will learn about the design parameters for making a RMH, and will assist in the full construction of a functional heater, from creating an insulated base to laying out the chimney, from assembling the fire brick core to putting on a decorative finish.

The workshop will pay particular attention to appropriate design, sourcing of materials and the use of recycled and natural building materials in the creation of a RMH.
