<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>

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

<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>
