    That is not watts...that's VA. There is a big difference.

    Watts is a smaller number than VA.

    A single, 3-way valve with an auto flow valve in the bypass line sized for minimum flow rate as far from the pump as possible and you are done. Easy. Easy to size. Easy to maintain. Easy to setup.
