Hi Everyone! I'm long time natural builder recently moved backed to cooler climes. This is also my first post!
I'd like to heat a hot tub with a rocket stove and have been scouring the internet for a good design.
Basically if I build a standard RS with an insulated inner burn chamber, where would the best place be for a copper heat exchanger?
I thought maybe around the inner stack encased in insulation, then continue spiralling around the outside of the inner stack in the combustion barrel and finally out to the water return.
I would love to hear other folks' experience and / or advice.
Thanks!
Patrick
