ALPHA HWR is a high-efficiency circulator fitted with a stainless-steel housing. It is built with an ECM (Electronically Commutated Motor) for maximum performance. It is designed to circulate domestic hot water in systems with a dedicated return line. The circulator comes with built-in temperature control, eliminating the need for an external aquastat. This small, compact hot water circulation pump provides instant hot water to the homeowner and fits with tank and tankless water heaters. The ALPHA HWR meets the energy conservation standards for circulator pumps that the Department of Energy established, which will take effect in May 2028.
