Hello everyone I am new here. Been doing a lot of reading about RMH. It gave me the idea to make an outside RMH to help heat a swimming pool. I am not looking for supper hot just around the 80F range. I was thinking that the J style RMH would. Be the best style to put in. I am thinking of doing like a 12-16 in feed tube with a 2-3 foot burn chamber. With a 4-5 foot riser. Now I don’t know if those sizes would work together or not as this will be my first RMH. I wanted to put the burn chamber and the riser inside a 55 gallon barrels so I can put rock/ sand in the barrels for my mass. Inside the mass material I was going to run 1/2 in copper tube wrapping around the burn chamber and riser. This will all me to get the heat without direct flames to the copper. I would be using. A small pump to move the water through the system so it will always be moving.
Dose this design sound like it would work? Also what is recommended to use for the burn chamber pipe? I am thinking 6in. Any and all suggestions would be great
