What it is
The Ariston 65116696-01 is a 30kW heat exchanger used in Ariston ONE series gas boilers. It transfers heat from the combustion circuit to the domestic hot water and central heating water within the appliance. The component is specific to the 30kW output models listed below.
Signs this part needs replacing
- Domestic hot water temperature fluctuating or running cold during draw-off
- Kettling, banging or gurgling noises from the heat exchanger during firing
- Water weeping or staining around the exchanger body or its connections
- Reduced hot water flow rate or poor heating performance despite correct boiler pressure
- Repeated overheat lockouts or a boiler that cycles rapidly on heating
Before you order
- Confirm the boiler model and GC number against the fitment list above
- Check the appliance is the 30kW variant, as this exchanger is output-specific
- Verify the part number on the existing component before removal
- Assess the system water quality and plan a flush and inhibitor dose if the exchanger has scaled or sludged
