Hi Brian,
Great alternative and _proven_ solution. Moreover, the sanitation aspect
to heat the water once per use all but eliminates the prospect of
breeding "bugs" in the stagnant warm water. It is my understanding that
spas/hot tubs that continuously reheat the same water need to have
chemicals added to keep them sanitary (at least that is the way it works
here for a public spa/hot tub).
One other item, necessary to mention for all the rest of us not living
in the relatively mild CA/coastal climate-since the tankless stores no
heated water all tankless water heaters are subject to freezing
conditions. Oh, yes, one can take on Mother Nature and add electric
heaters, anti-freezing firing, etc. but for real world practicality,
don't subject water to freezing conditions. Solution: mount the tankless
inside the heated structure and run the hot tub line through a freeze
protected faucet.
Thanks for sharing, Brian,

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.

*Subject:* [RE-wrenches] Chofu Hot Tub Heater
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
