NAVIEN 30011534A Flow Sensor

The Navien Tankless Water Heaters 30011534A Flow Sensor is an essential part of Navien Tankless Water Heaters condensing boilers, particularly the NPE/S series. It has the essential function of controlling the flow of water within the boiler heat exchanger. This sensor is in effect a flow rate sensor that checks the flow rate of water through the system to assures efficiency. The sensor is then able to measure the water flow and then the boiler has to regulate the amount of gas it uses. This means that users are able to set a preferred hot water temperature and this is maintained throughout, the boiler does not over heat and essential fuel is not wasted.
