ALPHA HWR 15-29 SU/T is a high-efficiency circulator fitted with a stainless-steel housing. It is designed for circulating domestic hot water in systems with a dedicated return line. It features an integrated digital timer which enables scheduling through the Grundfos GO app and eliminates the need for a physical programmable timer. It also features the ability for the homeowner to set their own schedule through the Grundfos HOME App. With the use of its integrated temperature estimator, ALPHA HWR helps reduce complexity during installation as an external temperature sensor is no longer needed. The AUTOADAPT setting offers a simplified setup process removing the need to decide what setpoint to use. With FLOWSENSE, ALPHA HWR can solve a number of challenges commonly found in domestic hot-water recirculation systems. By using flow limits, ALPHA HWR reduces the risk of flow-accelerated corrosion in the recirculation pipes by reducing the flow velocities while still providing enough flow to start the most common tankless boilers.
