The ALPHA 15-55 HWR-D COMFORT is a hot water recirculation system to provide comfort in homes with no need for return line or electricity under the sink. The ALPHA 15-55 HWR-D COMFORT starts via remote activation push button when there is a demand for hot water. The push button will start the pump via a Bluetooth signal and will circulate hot water until the water entering the COMFORT Valve reaches a temperature of 102 °F or has been operating continuously for 5 minutes. This innovative design is built on the current Grundfos ALPHA platform, offering high energy savings, low noise levels and a quick installation.

The ALPHA platform is a high efficiency platform with a permanent magnet motor (ECM). The ECM motor design reduces energy consumption by up to 50% and is built on over 17 years of Grundfos ECM experience, making it the most energy efficient product in the market. The pump functionality allows the homeowner to only run the hot water recirculation pump when there is demand, saving thousands of gallons of water a year. All controls and software are built into the product by Grundfos making installation simple with intuitive troubleshooting if necessary. The ALPHA 15-55 HWR-D COMFORT is an innovative, technologically advanced, energy efficient, and water saving solution for hot water recirculation.
