Grundfos Pumps Corp. has introduced the ALPHA 15-55 HWR-D on-command pump, the most energy-efficient residential hot water recirculation system available in the United States. The system reduces homeowners’ energy consumption by up to 50 percent, saves thousands of gallons of water per year per household, and meets regulations such as California Energy Commission Title 24 Building Energy Efficiency Standards. The ALPHA 15-55 HWR-D system’s circulator includes plug-and-pump technology and the trusted Grundfos permanent magnet motor.
When hot water is needed, a simple push-button control activates the pump via a Bluetooth signal. The pump then runs for five minutes or until the water entering the piping reaches 102 degrees Fahrenheit, as indicated by an external temperature sensor.
