Hydraulic separation

Hydraulic separation is the design principle or pipework arrangement that decouples two wet-heating circuits so a heat source circuit and a distribution circuit can run at their required flow rates with little pump interference. In heat pump and boiler systems it may be created with closely spaced tees, a low loss header, a buffer tank or a plate heat exchanger, depending on the design. It is not the same as hydraulic balancing, a buffer tank, heat pump sizing, primary pipework sizing, MCS certification, warranty approval or proof that a heating system is efficient or correctly designed.
