I have a house in the laurentiens which I want to heat with a rocket stove mass heater:
I've seen videos where people make their own custom rocket stoves but I don't have any welding equipment
and living in laurentiens there is no clay to be found so what material can I use for the mass?
Is there anyone in Quebec who knows about rocket stoves? Help!
There is no need whatever for welding in building a rocket mass heater. Using metal in the combustion zone (like many many youtube videos) is a very bad idea, as it will fail soon as the hot corrosive atmosphere attacks the metal. Metal downstream where it is cooler is fine.
