Gentlemen and Ladies,
If you really want a powerful therapeutic whirlpool in your hot tub, the
best solution I have experienced is a portable vintage Jacuzzi J300-B,
1/3 HP, 115 VAC, 5.6 A, manufactured by Jacuzzi Research, Inc. in
Berkley, CA. 28 pounds. This model was available before GFCIs became
commonly available, so original users were more than a bit of an
adventuresome breed. It is intended for tub use but a snorkel on the air
tube would allow "deep water" placement.
Today, eBay has six units listed, ranging from $100 to $450 plus
shipping including pink and turquoise as well as white, some sellers
quote 1950's vintage. Not exactly the longevity you would get from a
current day Jacuzzi _branded_ product.

Stay warm,

I think the jet tub is the better way to go for off grid. You are
only heating the water and running the circ pumps a few hours/ week,
and as Bill mentioned: no chemicals.
I've tried all of the choices, and while hot water alone is nice,
having the massage bubblers is definitely better. Not having
chemicals and/ or nasty recirculated bacteria is also much better
than regular hot tubs. Off grid folks don't have to do with out
modern conveniences, instead they can do it even better.
If you wanted to get savvy, you could recycle the water after to a
grey water cistern dedicated for toilet flushing and irrigation.

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
