Hot water heater is AC 120V. Water is also heated via the engine. Ran the
engine for about 10 minutes and got "warm" water. I'll probably never have a
use for it. The sun shower uses less power.

I, for one enjoy hot showers. I'll admit that we used the sun shower a lot on the
Nonsuch - it was more comfortable than the propane heater, but the AC/engine heater on the
cat works just great.

Two points: Don't leave the AC power on unless you really mean to. If it runs out of
water it can cook the heating element. I've never done it, but an absent-minded friend
started uying elements in bulk.

If you really don't intend to use the engine heating option, you might consider
disconnecting (bypassing) it. There is a risk that an air bubble can reduce water flow
and limit the cooling capacity of your engine. At the very least, if the heater lines are
above the engine, make sure there's a way to vent the air and top off the coolant.
