RE: Heat pump's integral circulator pump

@robs Thanks for this. The statement about 8C was not mine. It came from a Brendon quote. The flow rate shown is the current one. Are you saying that...

RE: Heat pump's integral circulator pump

@jamespa Let me throw my hat into the ring on this one. If one accepts that a delta-T of 5C is required for correct operation of a heat pump, then he...
