What it is
This is a heat exchanger manufactured by Ferroli, part number 39846940. It is used on Modena 32S and T-ONE 32S HE boiler models, where it transfers heat from the combustion circuit into the domestic heating and hot water system. It is a component-level part, not a complete appliance.
Signs this part needs replacing
- Visible leakage or weeping from the heat exchanger body or its connections
- Persistent pressure loss on the boiler with no external leak found elsewhere on the system
- Overheating or repeated high-limit trips during normal operation
- Kettling, banging or rumbling noises from the heat exchanger during firing
- Discoloured or scaled waterways, or restricted flow through the exchanger
Before you order
- Confirm the boiler model and, where available, the appliance serial or model reference against the fitment list above
- Check the existing heat exchanger for the same part number 39846940 before removal
- Confirm whether the fault is with the heat exchanger or with an associated component such as the pump, sensor or expansion vessel
- Isolate the gas, water and electrical supplies before any work, and use a Gas Safe registered engineer where gas-carrying components are involved
