Properly sizing and operating circulators Reducing head loss reduces the kWh of electrical energy required to operate them. John Siegenthaler, P.E. July 21, 2017 When designing hydronic circuits, most of us focus on what’s necessary for that circuit to absorb thermal energy at a heat source, carry it along like a conveyor belt and release that energy at one or more heat emitters.Read More
