The Ariston domestic hot water flow switch for the Aco, Intesa, Uno, eco Combi and Tristar boiler ranges. As an important safety mechanism, the flow switch has an inbuilt sensor that sits inside the heating or hot water system pipework. The switch is designed to sense water flow and feed information to the boiler's printed circuit board to ensure that the burner is not activated when the system is low on water or dry.
