The working principle of the instant electric water heater is to quickly heat the flowing water through electronic heating components, and can control the water temperature, flow rate, power, etc. through the circuit to make the water temperature reach the temperature suitable for human body bathing.

The basic characteristics of instant water heaters are: cold water is superheated and hot water comes out, as long as the water outlet is opened, hot water can be continuously supplied within a few seconds, and when hot water is not used, just turn off the faucet.

Among them, the heating system is the key to realize the intelligent frequency conversion and constant temperature of the instant electric water heater.

 So, what is the principle of the constant temperature of the instant electric water heater?

There is a temperature sensor at the water inlet end of the instant electric water heater, which can sense the temperature of cold water and transmit the information to the control chip. At the same time, the water flow Hall switch can sense the size of the water flow, and also transmit the information to the control chip. The control chip then quickly calculates how much working power is needed to heat the water to the specified temperature according to the water flow rate, water temperature and the temperature set by the user, instead of working at the rated power all the time, so the instant electric water heater has Features of automatic frequency conversion and constant temperature.

It is worth noting that there is also a temperature sensor at the water outlet of the instant electric water heater, which can sense the temperature of hot water. If it is higher than the safety value set by the manufacturer, it will trigger the over-temperature protection function. If the water temperature does not reach the user's setting, it will automatically adjust the working power.
