What is a water heater

A water heater is a type of water heater designed to meet the drinking water needs of various groups of people, which uses electricity to convert into heat energy to heat water. Its capacity is roughly divided into 18L, 25L, 27L, and 30L according to the needs of different groups, with power ranges of 2KW, 3KW, 4.5KW, and other different models. It is suitable for public places such as enterprises, hotels, troops, stations, airports, factories, hospitals, and schools. Compared to traditional boilers, they have the advantages of safety, low noise, and no pollution, and the supply of boiling water is available at any time regardless of the time period.

Principle of Water Boilers

After the correct installation of the water heater, connect the water source and power supply. When the liquid level control system senses that the water level has not reached the lower level (safe heating liquid level), first connect the solenoid valve, and the water heater will start to fill. At this point, the temperature displays the inlet water temperature. The water level indicator light and heating indicator light are not on;

1. When the water level reaches the lower level (safe heating level), the control board disconnects the solenoid valve, pauses water intake, and connects the heating system. At this point, the water level indicator light flashes, the heating indicator light lights up, heating starts, and water replenishment stops. After reaching the set inlet water temperature, the system will inlet water again while heating continues; The amount of water entering each time is about 2 liters (depending on different models and water temperatures); Feed water again and heat until the upper liquid level is reached, the water level indicator light remains on, and the water replenishment stops; Continue heating until the temperature reaches the set temperature, and the heating indicator light will turn off.

2. The main technologies adopted are as follows: multi gear heating technology: the application of leading instant heating technology and intermittent "multi gear" heating technology can meet the demand for instant continuous water pumping, while comprehensively being more energy-saving and energy-saving; Steam preheating technology: Boiling causes excess steam to be directed into a high water level cold water pipe to preheat the cold water, which is energy-saving and avoids the negative effects caused by excess steam diffusing into the surrounding environment.

What are the types of water heaters

Classify by occasion

Commercial electric water heater: Commercial electric water heaters are used in various public commercial occasions, with a large volume and a capacity generally of 15 liters or more. The power is generally above 3KW, with a maximum of 21KW.

Household electric water heater: Household electric water heaters are generally used in the kitchen of households, and can be placed under the kitchen sink or hung on the wall of cabinets. They are compact and use tap water or purified water as the water source. Boiled water can be used for drinking, cooking, boiling soup, blanching vegetables, disinfecting tableware, and baby items. The power of household electric water heaters is generally between 800W-1500W, which can be withstood by ordinary household circuits.

Campus electric water heater: The campus electric water heater is designed to cater to the drinking habits of students and employees on campus. This water heater has unique steam heat recovery and hexahedral insulation technology, which can be 100% boiled. The box does not emit steam and is not hot to the hands, making it suitable for campus use. Provide school teachers and students with direct access to drinking water.

Classified by technical principles

Electric water heaters, classified according to technical principles, include traditional water heaters, warm water heaters, boiling water heaters, stepper water heaters, instant water heaters, electromagnetic water heaters, steam water boilers, and purified water heaters.
