I would like to build a rocket stove mass heater in a home i am building. I have a couple of questions.
1. Can I build it out of normal fireplace fire brick and morter.
2 in the mass heater area can I incase the pipes with normal concrete instead of cob and put a stone or granite seat on top.
I already have concrete on the project for foundations and such and it would be easy to use any extra concrete that would go to waste
and use it to go in all places normally covered by cob.
3. is there any other material to use instead of the 55 gallon drum. I'm thinking of something more decorative. Say a stainless steel tube
with a stainless top on it. Or a tube of fire brick and then covered with decorative stone and maybe soapstone top left over from the kitchen counters.
4. This building is in Idaho at about 7,000 Ft so its cold in winter. How do i feed the fire with a outside air. I dont want to draw cold drafts into the house in order to feed the fire. seems to kind of defeat the purpose .
