Hot water and boondocking

[Gardner Yeaw]

Chuck,
Thanks. By the way, My wife's name is Kathy also, so it seems
that wives named Kathy like the solution, so it must be a winner.
I like the idea of using relays so that the pumps don't fight each
other. I have a similar relay logic system in my home. The garage
and bedroom share the same supply side for the hot water heating
system, so I built a relay logic system that gives the bedroom
priority. A little boolean logic and some radio shack relays and you
are in business.
