Thanks for all the info!
I like Rich's water heater application, very clever. He doesn't need this
in San Diego, but I recall someone putting five gallon jugs of heated water
in the van before winter camping and he could heat the van all night.
This is a way to replenish the heat mass every day with a little driving
around and have a hot shower too:

hardware store to let flow in or stop. Ball valve has equivalent effect to
"plugging". Heats up 5 gallons of water from "ambient" to 120 degrees F in
about 15-20 minutes of driving. I rigged a Walmart BBQ meat thermometer
(probe inserted into tub of water) to display that up by dashboard, wiring
underneath van of course. Have used EVERY camp trip for about 8 years
now....works primo. HOT showers are a MUST for me when camping! If you
can, why not?

well...
that's close. Heater cirucits and main coolant circuits are unrelated in a
way.
the heater circuit is not therostated for example.
what will happen is less hot coolant will get to the front heater core.
the two circuits, main and heater, do not intersect except in the engine.
luv it ..on board fresh water heating while driving. !

had it looped for about 15 years. No ill effects. Just turned 210,000
miles on a 1.9, runs like new, no leaks, not one drip. Plugging is easier
anyway.
