An exciting new project! We are going to build a rocket mass heater: But it is super hard to make the right design since our house is made all of paper and straw and is designed in such a way that there is actually no place for it. After 2 years of thinking about it, I am now exploring the possibilities to build the stove actually outside the mainframe of the house in a cob-build extension, away from anything combustible, and then try to bring some heat back into the house through a small heated platform. Not ideal, but last winter had been the coldest in my life, so the motivation to do something is great. First: breaking down a rotten shed in the back. Then preparing a concrete base for a storage container. Next deconstruct and reconstruct the storage container on the place of the shed. Now I have a location for a clay pit And rubble for the base and old but dry wood for the future stove.
