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<span class="HOEnZb"><font color="#888888"><br>
