Electric water heater Usage method Electric water heater Scale Hazard

Electric water heaters are heated and unheated by turning on and off the thermostat. The general concept of heat preservation is short-term heating. When heating, the rated power of the water heater is still used. After the circuit is turned on, if the water temperature is lower than 50°C (the critical temperature set by most brands), the thermostat is automatically turned on and the water heater starts heating. The water temperature reaches the preset temperature of the water heater (most brands are 75°C～85°C When the thermostat is disconnected, the heater stops heating. Then, together with the Xiaobian to understand the use of electric water heaters and electric water heater scale hazards.

Electric water heater use method

1. Turn on the power and the indicator light is on. When the water temperature reaches the set value, the indicator light goes out. When the indicator light is on, the indicator light on indicates that it is automatically keeping warm.

2, electric water heaters (storage type) to be filled with water, and then heating, preheating can be used. (If the voltage is not stable, it is best to turn off the power)

3, the electric water heater temperature regulator, there are water temperature mark, indicating that the temperature adjustment, before use, you can first adjust the moderate temperature.

4, when used, unscrew the "red" color faucet, there is hot water out, the water temperature is too high, you can open the blue faucet at the same time, get the appropriate temperature.

Electric water heater scale damage

1, damaged water heater

Scale is a very poor thermal conductivity material, will hinder the heat transfer, resulting in uneven heating water heater, resulting in local overheating phenomenon, or local pressure is too large, and ultimately damage the water heater, or even dangerous.

2, resulting in lower water heater temperature, reduced water supply

The thermal conductivity of scale is much lower than that of metals. The thermal conductivity of metal pipes is 6 to 1000 times that of scale. Scales in the collector pipes can seriously affect the heating of water, and hard scale can reduce or even invalidate the conversion rate of electrical energy. And scale will occupy a certain amount of water storage space, resulting in reduced water storage.

3, harmful to health

Scale contains a variety of chemical components, long-term precipitation and accumulation of water heaters continue to increase the number of harmful substances, in addition, slime, microorganisms, bacteria in a long time constantly updated, alternate reactions also generate a lot of harmful substances, can cause a variety of The occurrence of skin diseases caused people to feel itchy and red spots after taking a bath.

Editor's summary: About the use of electric water heaters and water heater scale hazards are introduced here, and hope to help everyone. If you want to know more related information, you can pay attention to this website information.
