The Navien Tankless Water Heaters 30000666A Gas Pressure Flow Sensor is a crucial part that assure the efficiency and safety of the HVAC systems. This sensor helps the system to have complete control and efficient in operation because it continuously determines the pressure and flow of the gas inside the system. However, for the sensor to function it has to first sense changes in the pressure and flow of the gas. It then transmits actual data to the control system and the gas supply is adjusted accordingly. This leads to longer lasting systems, lower cost of operation, and increased energy efficiency.
