Gas water heaters with draft sensor
Draft sensor
— a sensor that monitors the presence of draft in the chimney of a gas water heater.This function is important for models with open combustion chambers: in the absence of a draft, combustion products will fill the room where the heater is located. And this, in turn, can lead to a deterioration in people's well-being, health problems and even deaths. To avoid such consequences, this sensor, when it detects problems with the draft, turns off the gas supply and issues a warning about the problem. However, such equipment can also be found in models with closed combustion chambers — in them, the draft sensor performs mainly a diagnostic function, allowing you to determine what interferes with the normal operation of the burner.
