Concrete Rocket-Mass-Heater

A firstĀ  preliminary design for a concrete rocket-mass-heater…The goal was to use standard materials and a single face casting mold for pigmented concrete elements to enable a simple workshop with small start-up investment to build it.

I have moved on to a (sheet)metal and Calcium Silicate Casting version aiming to be more fit for mass production, integral & more flexible.
