What Is a Boiler Flow Switch? This Simple Guide Explains the

The boiler flow switch prevents burner operation when the system is in bypass (no flow) mode and should be mounted as close to the boiler inlet as possible. If the burner fires when the system has no flow, it can result in the superheating of water trapped in the water tube which will lead to a failure. The flow switch also prevents the boiler ...
