The strong exhaust type water heater actually uses a very long heat transfer tube and a heat exchanger with a large contact area of metal. It transfers the heat from the burned gas to the metal sheet to heat the water, thereby making the exhaust gas temperature extremely low. The strong exhaust water heater has an extremely high thermal efficiency. The wind pressure short-circuit protection of the strong exhaust water heater provides better protection for the safety of users. The function of wind pressure short-circuit protection for the water heater is indispensable.
The strong exhaust type water heater is an extension of the flue type, with an additional exhaust gas motor. The exhaust gas is discharged to the outside through the flue. During operation, the exhaust gas is forcibly discharged to the outside through the flue, but the oxygen required for combustion still comes from the interior. (Borane Network) The wind pressure short-circuit protection of the strong exhaust water heater provides better protection for the safety of users.
The forced exhaust type gas water heater forces the exhaust fumes to be expelled outward through an exhaust motor installed above the water heater, thus quickly removing the combustion exhaust gases from the room. The gas water heater is powered by an external plug, and its internal components mainly include: pulse igniter, ion sensor probe, temperature controller, air pressure switch, fuse (some gas water heaters have it), start capacitor, exhaust motor, push-button switch, valve control electromagnetic valve, water control valve, water and gas linkage device, burner, circulating water tank, main circuit control package, ignition indicator light, temperature display screen (the old ones do not have it), gas proportion regulating valve (the old ones do not have it), etc. With the development of science, some new technologies are used, and some new components are gradually added. Here are some common components. The forced exhaust water heater's air pressure short-circuit protection better protects the safety of the users, so it is an indispensable component. The technical library has abundant and comprehensive information, and we welcome your reading!
When power, water and air are all connected, the water flow pressure activates the micro-switch, causing the exhaust fan motor to start and discharge air. At the same time, the pulse igniter begins to discharge electricity, and the gas control solenoid valve opens to allow the gas flow to enter the combustion chamber. The gas encounters the electric spark and ignites, starting the heating process of the circulating water tank. Hot water flows out quickly after the cold water is discharged. If the water temperature exceeds 50 degrees, the temperature limit controller will be activated, cutting off the power supply and extinguishing the gas. If the outdoor wind pressure is too high or the flue is blocked, the long-term use of the circulating water tank causes the heat exchange plates to melt and stick together, resulting in poor exhaust. The wind pressure switch will then turn off the power supply and stop the gas water heater from working. Usually, the wind pressure switch is prone to failure, manifesting as: the gas water heater can start, but it automatically shuts off within a few seconds or minutes. The wind pressure short-circuit protection of the water heater brings convenience for people's use safety.
