In some public places with high demand for hot water, the use of appliances such as electric kettles cannot meet people's water needs. In this case, instant water heaters are generally used, which can greatly meet people's demand for hot water. Proper maintenance and upkeep is one of the important tasks in the use of instant water heaters.

Working principle of instant hot water boiler

The large water tank of the water heater is not equipped with a mechanical control valve. It enters the water through the inlet solenoid valve for heating. When the water level naturally rises, the entertainment part of the water flows into the faucet. As long as the faucet is turned on during use, it can be used. If there is no water connection, the sensing signal immediately informs the system to close the water inlet and heating, and the water and electricity work continuously, waiting for the next time to turn on the faucet.

When cold water flows in from the bottom of the heater, the joyful boiling water at the top is discharged. After boiling water overflows, the sensor informs to add cold water to ensure continuous circulation. The amount of cold water is equal to the amount of water entering, the faucet is continuously turned on, and the outlet temperature stabilizes above 98 degrees. During the heating process of the water heater in the DC heating chamber, once the faucet is closed, hydroelectric power generation will immediately continue, and many excess steam will enter the heat exchange chamber for heat recovery. Together, the cold water tank absorbs a lot of heat energy, preheats the water temperature to 30 ℃ -40 ℃, and then enters the heating chamber through a joint receiver, heating from the temperature of the unopened water to the boiling point (100 ℃), only heating at 60 ℃ -70 ℃. A lot of hot steam is not wasted, but is sent to the bottom preheating cold water source through condensation principle.

Maintenance of instant hot water boiler

Step 1: Power off, open the outlet at the bottom of the water heater, drain the remaining water from the heater, and close the outlet; Step 2: Open the lid on the top of the water dispenser; Step 3: Initially participate in white vinegar from the top. Generally, only two bottles of vinegar are needed for instant water heaters, and only one bottle is needed for wall mounted water heaters; Step 4: Fill the water with water and soak the top water level probe for about 4 hours; Step 5: Flip open the outlet, drain the water from the water dispenser, inlet water from the beginning, and clean.
