What it is
This is the Chaffoteaux main heat exchanger, part number 61011136. It transfers heat from the boiler's combustion gases to the domestic water circuit in compatible Ariston and Intesa boiler models. The component sits at the centre of the appliance's hydraulic and combustion path, and its condition directly affects heating and hot water performance.
Signs this part needs replacing
- Water weeping or staining around the heat exchanger body or its connections
- Kettling, banging or rumbling noises during firing, indicating scale or restricted waterways
- Reduced heating or hot water output despite the burner firing correctly
- Repeated overheat lockouts or high-limit trips
- Visible corrosion, pitting or deformation of the heat exchanger casing
Before you order
- Confirm the boiler model and GC number match one of the fitments listed above
- Check the existing heat exchanger's part number against 61011136
- Verify the system has been correctly dosed and that water quality is not the underlying cause of the fault
- Work on the boiler's combustion and hydraulic circuits must be carried out by a Gas Safe registered engineer
