Gentlemen and Ladies,<br>
<br>
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.<br>
<br>
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 <u>branded</u> product.<br>

<div class="moz-cite-prefix">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.<br>
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.<br>
If you wanted to get savvy, you could recycle the water
after to a grey water cistern dedicated for toilet flushing
and irrigation.<br>

Hi Brian,<br>
<br>
Great alternative and <u>proven</u> 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).<br>
<br>
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. <br>
<br>
Thanks for sharing, Brian,<br>

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.</span></p>

<p class="MsoNormal">Wrenches,<br>
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."<br>
<br>
Does anyone have a line on where one can be located
before they're all gone? Or a good alternative?<br>
<br>
Thanks, Allan</p>
