[C38] water heater

[Patrick Harpole]

I disconnected my water heater from heat exchanger.   I get hot water while
"wired" to dock with electric water heater.

If the waterheater fails by developing a leak in its heat exchanger, the
fresh water supply will be  contaminated, but the engine will still have
cooling as long as there is water in the tank, although at some reduced
pressure, and it will slowly boil off the freshwater.  But you should
have some time to run the engine and get home.  The hotwater tank will
vent pressure if steam forms, and of course the engine will still be
controlled by the thermostat.  The temp will rise because the loop loses
pressure.  This happened on JACE when we were on our check sail.  No
harm done.  The ownere at that time was a bit disturbed, but it was OK.
(and I bought the boat.  Maybe I should have haggled some more ;-)
