Heat Pump 3 Port Diverter 28mm

The Heat Pump 3 Port Diverter 28mm is a motorised valve that directs water flow between heating and hot water circuits in domestic heat pump systems.

  • 28mm compression connections for standard pipework integration
  • Three-port diverter configuration controls flow to one zone at a time
  • Replaceable powerhead allows maintenance without system drainage
  • Quiet operation with minimal electrical power consumption

This valve manages flow distribution in fully pumped central heating systems with separate radiator and hot water cylinder circuits.
