I've set up a secondary return to an unvented cylinder powered by a bronze circulator (Circulating pumps SE50B). The circulator is controlled by a timer and a pipestat fixed to the furthest point of the circuit.
Even though the pump control is set to the lowest power (1 of 3) it's still much more powerful than it needs to be (causing a noticeable noise when running) and I'd like to know if there's a way of downrating it.
I thought about putting a resistor in series (what type and rating?), but I suspect that some of you might know of something a little more sophisticated.
