Water Heater Recirc. Pump
Posted by Brian on July 20, 19100 at 18:03:40:
I'm plumbing a new house, and I want to use two 40-gallon water heaters. I intend to use three
recirc. pumps to keep hot water at the three most distant bathrooms. (They're each plumbed back
to the same place - sort of a manifold configuration.) Should I plumb the water heaters in parallel,
in order to get the best flow, or in series? Also, do you have any suggestions on plumbing the
three recirc. pumps into the same hot water heater? (I assume I can just build a manifold, and
I'll probably have to use anti-backflow devices at each pump and at the cold water inlet to the water
heaters...)

Thanks!
