What it is
The Baxi 242500 is a rubber seal kit for the heat exchanger, manufactured by Baxi for use across its combi and Solo gas boiler ranges. It seals the heat exchanger joint, preventing water loss from the sealed system at that connection. The kit is listed for Baxi and Potterton appliances including the Combi, Solo, 100HE, 80/2 HE and Platinum families.
Signs this part needs replacing
- Water weeping or dripping from the heat exchanger joint
- Visible cracking, hardening or flattening of the rubber seal
- Corrosion or scale staining around the heat exchanger connection
- Falling system pressure with no other visible leak
- Water traces on the boiler casing below the heat exchanger
Before you order
- Confirm the boiler model against the fitment list above, as the seal suits specific Baxi and Potterton appliances.
- Check the GC number on the appliance data badge if the model name alone is ambiguous.
- Confirm the leak originates at the heat exchanger seal rather than a nearby pipe joint or connection.
- Isolate the electrical supply and shut off the water before opening the boiler casing.
