The Grundfos ALPHA3 sets a new standard for domestic circulator pumps. Following on from the popular ALPHA2 range, the new ALPHA3 adds the unique hydronic balancing feature. By combining the ALPHA3 pump with the new Alpha Reader and associated Grundfos Go Balance mobile app, the installer is able to achieve accurate hydronic balancing in the system, in about half the time of traditional methods. The balancing system works with two pipe radiator systems.

The pump is suitable for use with constant or varying flow systems, one-pipe or two-pipe radiator systems and underfloor systems.

Key Features:

  • Unique hydronic balancing technology (requires Grundfos ALPHA Reader - sold separately, and free smartphone app)
  • Class-leading energy efficiency, with included insulation shell to prevent heat loss - uses 83% less energy than average units
  • AUTOadapt technology for fast, automatic commissioning
  • Standard-sized 130mm port-to-port length for easy replacement of many existing pumps
  • Detachable power cable to ease maintenance

Note: a union kit may be required for installation (sold separately)
