In winter, frequent use of electric water heaters not only facilitates home life, but also presents potential safety hazards. What should you pay attention to when using an electric water heater?
1. The room temperature is relatively low. After the hot water flows out, a large amount of heat is quickly dissipated into the air, which reduces the heat of the water. Therefore, the temperature can be appropriately increased in winter and the electricity bill can be effectively saved. The electric water heater can plug in the power for a long time, which can reduce the energy consumption when the electric appliance starts, and it is more power-saving. When the frequency of use of electric water heaters is relatively low, such as when the electric water heater is not used for more than three days, the power supply should be unplugged and then plugged in again before use. This will save more power.
2, the degree of water heater is adjusted to about 65 degrees Celsius, when electricity is the most economical. Use water storage type electric water heaters with good insulation properties to regularly remove the scales and debris from showers and strainers to avoid clogging and affect the results.
3. Install Yuba in the bathroom to increase the ambient temperature and prevent colds. At the same time, the height of the spray head can be lowered so that the warm water mixed from the water heater can be sprayed onto the body in the shortest possible time to reduce heat loss.
4, the use of electric water heater power cord, must meet the water heater rated current requirements. First use or maintenance, first use after cleaning, must first fill the water heater and then turn on the power. The power outlet must have a reliable ground wire. When using, do not pull the power plug with wet hands.
5, the life of electric water heaters generally will not exceed 6 years, if you continue to use more than the age limit, there will be security risks, we must promptly replaced.
