Customized 6L 10L 12L Gas Geyser Wall Hung Instant Gas Water Heater

The control system of a household gas water heater is an electronic control system, usually equipped with a flame detection device and a control device. The control system has electronic ignition, flameout protection, safety interruption, constant water temperature, overheat protection, incomplete combustion protection functions, as well as re ignition, human-machine telephone display, alarm function, and remote control function. There are three types of gas water heater time sequence controller, digital controller, and fuzzy controller.

The basic working principle of a gas water heater is that cold water enters the water heater and flows through the water gas linkage valve body. Under a certain pressure difference of the flowing water, the water gas linkage valve is pushed, and the DC power microswitch is also pushed to connect the power and start the pulse igniter. At the same time, the gas transmission electromagnetic valve is opened, and the pulse igniter continues to automatically ignite again until the ignition successfully enters the normal working state, This process lasts for about 5-10 seconds continuously. When the gas water heater experiences faults such as water shortage or insufficient water pressure, power shortage, gas shortage, high hot water temperature, or accidental blowing out during operation or ignition, the pulse igniter will automatically cut off the power supply by detecting the feedback signal from the induction needle. The gas transmission solenoid valve will immediately return to the original normally closed valve state in case of power shortage, which means that the gas has been cut off at this time, Turn off the gas water heater for safety protection.
