Since87, thanks for the data. I gather from your explanation that the gains to be made from a parallel system are negligible compared to a series setup? ( with low restriction blocks)
With the pressure drop much higher for the serial loops, isn't the pump essentially having to work harder and meeting more resistance?
And so wouldn't the pump (having to work harder against more resistance, and generating more heat) dump more heat into the system when in series than in parallel?
I know the effect on the temps is determined by just how much these factors influence each other, but to prolong the life of the pump and reduce heat dumped into the circuit by it, would the parallel be better?
And by how much?
I'm trying to
