The Biasi BI1271501 Flow Switch is a genuine replacement safety component engineered to monitor water flow within compatible Biasi boiler systems. This precision flow switch detects when water is moving through the heat exchanger and signals the boiler’s control system to allow ignition and normal operation to proceed only when adequate flow is present. If flow drops below the required threshold, the switch helps the boiler enter a safe lock-out state to prevent overheating and protect internal components.

Compatibility for the BI1271501 flow switch includes Biasi boilers that utilise this specific flow-sensing device; always check your exact boiler model and part specification before installation to ensure correct fit and reliable performance.

Using a genuine Biasi flow switch helps maintain safe operation by ensuring the boiler only fires when proper water circulation is detected, supports efficient heating performance, and contributes to the long-term dependable and safe functioning of your central heating and hot water system.
