I am thinking about making a racket mass stove for my studio. I was really cold last winter!I have 2 questions. Could I bould a rocket mass stove in an old cast Iron bathtub? The reason I'm asking is because there is a tub in my studio and it is to heavy for me to .
The second question is about the materials you are using for the thermal mass. I have read before that of all the stones, bricks, sand, that people use for thermal mass, water is really the most efficient. Any thoughts on this? Thanks ahead of time. Fay
