ALPHA HWR 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. The ALPHA HWR also allows homeowners the ability to set their own schedule through the Grundfos HOME App. With the use of it's integrated sensor that estimates temperature, the ALPHA HWR helps reduce complexity during installation as an external temperature sensor is no longer needed. The AUTOADAPT setting offers a simplified commissioning process, removing the need to decide what set point to use. With FLOWSENSE, the ALPHA HWR can solve a number of challenges commonly found in domestic hot water recirculation systems. Through the use of flow limits, the ALPHA HWR reduces the risk of flow accelerated corrosion in the recirculation pipes by reducing the flow velocities while still providing enough flow to kick on the most common tankless boilers Circulator comes with built-in temperature control, eliminating the need for an external aquastat. Built-in digital timer makes it possible to schedule the pump's on/off hours, helping save energy when hot water is not required in the home. Master the flow to reduce pinholes with FLOWSENSE technology Dry run protection during set-up and normal operation monitoring to help from bearings and shaft seals being damaged Self venting in any setting and mode to help achieve a low noise level High efficency hot water circulator for dedicated return lines that will help for a smoother installation while providing a safe and efficient solution High efficiency platform with a permanent magnet motor (ECM) that helps reduce energy consumption by up to 80 percent AutoAdapt functionality to maintain temperature and prevent the pump from operating if return temperature is satisfied. Learning cycle adjusts flow rate to meet system Maintains one of the highest Engergy rating in the market (192) based on the Hydraulic Institute Energy Rating Touchscreen with LED lights field indicators with numeric display (flow, temp, watts)
