Hello everyone
Please advise
Is it possible to run the exhaust pipe of a mass heater from the barrel out side strait through the hot tub, in the water to warm it up?
Thanks

Hi Jack; Welcome to Permies!
Rmh's have been used to heat a hot tub before. So it can be done. I have no direct experience with building one. (I used to own a snorkle heater for a hot tub) Here is a link to an earlier post here at permie.
