[RE-wrenches] Chofu Hot Tub Heater

Hey Allan,



For many years, my wife and I have been using an old 6’ long claw-foot tub
as our hot tub on the mountain. The 6’ tub is large enough, but very cozy
for two people. We just run straight hot water from our Aquastar propane
water heater into it, which gets it very hot. It takes a little time to let
it heat up the cast iron tub, which cools it down just enough for a great
soak. It stays hot for a pretty long period of time, but If it gets too
cool, we just run more hot water into it.



Then we just use the gray water for garden irrigation the next day. No
chemicals, filters, or electricity needed.

Wrenches,
I have an off grid client who wants a hot tub, and would prefer a propane
heater rather than wood. The Chofu appears to be the only unit that doesn't
require a circulation pump. He had located this on his own, but told me
that "The propane fired, self igniting, hydrosiphoning Chofu is no longer
available domestically. Seems the Japanese do not wish to export these to
the USA anymore.  I will keep looking as this was the most sane idea for
the project and of course cheapest. Chofu listed on Island Hot Tub is
currently unavailable. I talked to him a week ago and it sounded like there
was no availability for the foreseeable future."

Does anyone have a line on where one can be located before they're all
gone? Or a good alternative?

Thanks, Allan
