Electric water heaters are mainly divided into direct thermoelectric water heaters, full-automatic regenerative electric water heaters, detachable and easy-to-remove electric water heaters, and electric thermal storage water heaters. Electric water heaters are mainly divided into instant electric water heaters, volumetric electric water heaters and stepping electric water heaters. These electric drinking water devices have their own characteristics, which are briefly described as follows:
1, the direct thermoelectric water boiler is compact and small, suitable for dispersing a small amount of water, and it can meet the demand of centralized pumping in peak hours only when it is matched with the insulation water tank;
2. The invention has the advantages of integrated boiling water storage, sufficient boiling water and guaranteed boiling water temperature, which is superior to the water supply mode of direct thermoelectric boiling water boiler with thermal insulation boiling water tank;
3. The easy-to-scale detachable electric water heater is mainly for easy scale removal. It is an upgraded version of the automatic regenerator electric water heater, especially suitable for units that use groundwater and alkaline water sources;
4. The electrothermal regenerative boiling water boiler is designed with single cabin and large capacity, and the boiler water with rated capacity is boiled and stored in about 8 hours. Therefore, the wattage of the electric heat storage water heater is relatively small, and it is generally set to heat at night during off-peak hours to meet the demand for water intake during the day.
5. Instant water boiler, also called "Instant water boiler" and "Instant water boiler". The instantaneous opening of water is realized by pipeline heating, so the electric power is high. Its basic feature is "ready to use, without heating", and it is mostly installed in office places where water is received by water cups.
6. The positive displacement electric water heater is a traditional floating ball type water heater with beautiful appearance, convenient installation and low price, but it has the disadvantages of "thousand boiling water" and "yin and yang water", which is not conducive to drinking water health, so it is rarely installed in schools now;
7. Step-by-step electric water boiler feeds water from the bottom, heats it step by step and gradually heats it until the water boils. Water supply, heating and water intake do not interfere with each other, there is no "thousand boiling water" and a little "mixed water", and the water temperature is guaranteed.
Knowing the essential characteristics of these electric water boilers and water boilers, it is much easier for us to choose. In addition, it is recommended to choose electric water heaters from regular manufacturers, such as registered trademarks and product patent certificates.
