What it is
The Biasi BI1462103 is a complete circulating pump for Biasi Activ A series gas boilers. It moves water around the boiler's primary circuit and the heating system, so a failure here stops both heating and hot water production. This pump is specified for Activ A appliances built up to April 2011.
Signs this part needs replacing
- Boiler runs but radiators stay cold, or heating output is weak across the system
- Pump body is noisy, with rumbling, humming or grinding during operation
- Boiler locks out or shuts down shortly after a demand for heat
- Water weeping or staining around the pump housing or its connections
- Pump runs intermittently or fails to start when the boiler fires
Before you order
- Confirm your appliance model against the fitment list above, including any LPG variant
- Check the GC number on the boiler's data badge where one is listed
- Verify the appliance was manufactured up to April 2011, as later builds may use a different pump
- Compare the part number on the existing pump with BI1462103 before ordering
