What it is

The EXPANSION VALVE (HEAT) is a Glow-worm component used on the Envirosorb 14 air/water heat pump. It sits within the appliance's refrigerant circuit and controls refrigerant flow in heating mode. The valve is listed under Glow-worm part number 0020086352.

Signs this part needs replacing

  • Reduced or inconsistent heating output from the heat pump
  • Frosting or ice build-up around the valve body
  • Unstable or fluctuating refrigerant pressures during heating operation
  • The valve fails to modulate, or refrigerant flow hunts instead of settling

Before you order

  • Confirm the appliance model plate reads Envirosorb 14 air/water heat pump
  • Check that the valve being replaced is the heating-side expansion valve rather than a cooling-side component
  • Match the markings on the removed valve against part number 0020086352
  • Ensure the refrigerant circuit has been recovered and made safe before work begins
