My wife and I recently moved into a house that has two 50 gallon
electric water heaters. They are about two years old. As it is just
the two of us, I would like to turn one of them off and see if one
heater can meet our needs.
I figure I need to:
- shut off the cold water intake, outflow to the heater that will be
- shutoff the crossover valve that connects it to the other heater
will will leave in use
- drain the unused heater
Anything else I should do?
I would shut off the electric, then after it's cooled, shut off the
water lines and leave it full. At least until you decide that it
works for you, which I guess it should. After that, still not sure if
I would drain it as it going to be nearly impossible to get all the
water out anyway and a tank full of water is less likely to rust than
one with a little water and lots of air.
If they are hooked up so hot water from one goes into the other one
then only turn off the power on the first one and use it to temper
incomming water to the second one. Incomming water is colder than your
turn off power and forget it, use first tank as pass thru tempering
tank, so water wouldnt get yuk.......
if you drain the tank the remaing moisture and air will make it leak
faster, rust just loves oxygen.
this is one that the simplest solution is likely the best
