Glow-worm Compressor 0020086322

The compressor is the pump's central refrigerant component, manufactured by Glow-worm for the Envirosorb 8 air/water heat pump. It circulates refrigerant around the sealed circuit, raising its pressure and temperature so heat can be transferred from the outdoor air into the heating and hot water system. It is supplied as a standalone component, part number 0020086322.

• The heat pump runs but produces little or no heating or hot water output.
• The compressor trips the supply, or the appliance locks out shortly after start-up.
• Unusual mechanical noise, knocking or vibration from the compressor area.
• The compressor fails to start, with the unit showing a compressor or high-pressure fault.
• Repeated overload or thermal cut-out trips during normal operation.

• Confirm the appliance model is the Envirosorb 8 air/water heat pump.
• Check the existing compressor's part number against 0020086322 before ordering.
• Verify the fault is diagnosed as a compressor failure rather than a control, sensor or refrigerant charge issue.
• Work on the refrigerant circuit requires the correct handling equipment and competence; confirm this before starting.
