ECA and Protherm combi boilers share many hot water components, and this ECA Protherm turbine reader is one of them. It is the hall effect sensor that clips onto the flow turbine and lets the boiler electronics know that domestic hot water is being drawn. Without its signal, the boiler has no way of telling […]

Airfel and Daikin combi boilers rely on a small sensor to recognise hot water demand, and this Airfel Daikin turbine reader is that sensor. It fits on the outside of the domestic hot water turbine and passes a pulse signal to the control board whenever water flows through it. Engineers also call it a flow […]
