I have a heat pump currently installed and I'm adding a gas heater....
what is the best way to plumb this ? In series with heat pump first then gas heater?
I've read that it's better to have water flowing through both then having water sit in one if not being used for a couple weeks etc.
Thoughts?
thanks in advance I appreciate your time!
