Grundfos ALPHA HWR SU/T Hot Water Recirculation Pump Circulation & Air Conditioning Pumps

The Grundfos ALPHA HWR SU/T hot water recirculation pump (also called a domestic hot water circulator or DHW recirculation pump) is for systems with a dedicated return line. It circulates hot water through the loop so it reaches fixtures quickly. This cuts the wait for hot water and the cold water that goes down the drain meanwhile.

Key Features:

• Stainless steel pump housing for use in domestic hot water systems
• High-efficiency ECM motor with variable speed operation and several operating modes
• Built-in digital timer to schedule on/off hours. Scheduling can be set through the Grundfos GO and Grundfos HOME apps, so a separate programmable timer isn't needed
• Integrated temperature estimator that removes the need for an external temperature sensor or aquastat, which simplifies installation
• AUTOADAPT and FLOWSENSE control functions that adjust pump performance to the system
• Dry-run protection to help protect the pump
• Union connections for quick installation and removal. Adapters for other pipe connection types are sold separately
• 115V single-phase power supply

The ALPHA HWR line combines the pump, timer and temperature sensing in one digitally connected unit. This makes it a good choice for homes and buildings that want instant hot water, lower energy use and simple setup.
