The ALPHA 15-55 HWR-D is a hot water recirculation pump started via a push
button when a demand for hot water is identied within the occupancy. The
push button will activate the pump via a Bluetooth signal and will run until
the water entering the water piping reaches a temperature of 102 °F,
as indicated by the external temperature sensor, or has been operating
continuously for 5 minutes. This innovative design is built on the current
Grundfos ALPHA platform, oering high energy savings, low noise levels
and a quick installation.
The ALPHA platform is a high eciency 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 ecient 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 and intuitive troubleshooting if necessary. The ALPHA
15-55 HWR-D is an innovative, technologically advanced, energy ecient,
and water saving solution for pump hot water recirculation.
