I have a Kohler whirlpool jet tub. I like to add an inline heater to the plumbing so that the water temperature is maintained. Does anyone have experience with installing such an inline heater to an existing whirlpool jet tub? There is a small access door at the end of the tub (opposite end of the faucets) but I have never opened the access door to see how much of the plumbing is accessible.

Thanks

When I purchased/installed our American Standard jet tub, one of the
options was such an in-line heater. I installed it at the time of the
original install however it was designed to be added at any time. The
main pump line was already for it with a removable blank to be replaced
by the screw in SS in-line heater. All I did was provide a separate
GFCI 15amp circuit. Check out Kohler's literature and see if the same
setup is available for your model.

I think I paid an additional $130 to $150 for the unit and it works
well. Totally automatic operation and installation no more difficult
than changing out a P-Trap and plugging in a lamp.

You wait right there, someone from Usenet will be right over to open
that door for you.

There are some serious issues involved, even if it is possible.
He might want to start with how the heater is going to be powered?
Usually a tub like that has a circuit for powering the pump. That's
probably on a 15 amp breaker. A heater would have to be fairly
substantial to be capable of heating a tub full of water. If the goal
is just to maintain it, less power will be required, but I'd think it
still would need something in the range of at least the typical
electric kettle. And those are 1200-1500w range, meaning
for this to work, he's probably going to need a second circuit.
That alone may be a show stopper, depending on where it's
located.

Then there are the various safety related issues, overtemp
protection for the heater, etc. And given the tight spaces
these things are in, etc, it definitely is not a trivial project.
