If this mechanical temperature control is fuzzy, it is impossible to be accurate to a few degrees, and you can turn the knob to control the outlet temperature of the water heater; (Red is high temperature, blue is low temperature). If the water mixing valve is used to control the temperature, the maximum outlet water temperature will not be higher than 75 degrees (boiling water at this temperature will not scale, and discharging water will not burn children); (Red is high temperature, blue is low temperature).

A.O. Smith innovated and developed Jingui special care heating rod, which made a breakthrough in anti-corrosion and anti-pollution ability. Jingui special protection system composed of Jingui inner container and American strong anode rod improves the overall quality of water heater and ensures long-term and efficient operation.
1) patent Jingui special protection heating rod: long-term efficient heating, durable and energy-saving: Jingui coating is tightly protected, durable and antifouling. Low fouling ensures that the heating rod maintains high heat transfer efficiency and runs efficiently for a long time.
2) Patent Jingui special protective liner: the coating does not fall off: fiber is added to the special glaze, baked at 870℃, and it adheres tightly and does not fall off. The coating does not break: the coating expands and contracts synchronously with the steel plate of the liner without breaking, which is more effective in corrosion prevention and scale prevention.
The hourglass or water leakage is the earliest timekeeping tool used by human beings, but after the birth and development of clocks, people began to try to use this brand-new timekeeping tool to improve the timer and achieve the purpose of accurately controlling time.
Timer is really an amazing invention, which makes many jobs that need people to control time much easier. People even use timers in the army to make time bombs and time detonators. Many household appliances are equipped with timers to control the switch or working time.
