Aqua Plus buffer tanks are designed to optimise heat pump hydronic systems. They create hydraulic separation between the heat pump and hydronic circuits, ensure optimal water flow through the heat exchanger, prevent inefficient short-cycling and aid the defrost cycle in freezing conditions. They can be installed outside, ideally near the hydronic heat pump. Note that prices are continually reviewed and may change prior to the new listing.
