Early signs of water heater explosion

Early signs of water heater explosion include the failure of thermostat and overheat protector.

1, thermostat failure

The thermostat of electric water heater is used to control the water temperature. If the water pressure is too low or too high, it can also play a role in regulation and protection. However, once the thermostat fails, the temperature of the water heater will keep rising, so it is impossible to control the temperature normally, and it is impossible to stop the water heater when the temperature is too high.

At this time, the steam in the electric water heater can't be discharged, the pressure becomes greater, and the water temperature will burn out the inner container, leading to the explosion of the water heater. If you set it to 60 degrees, but the water heater keeps heating, and the temperature even reaches 75 degrees, it is that the thermostat has failed.

2, overheating protector failure

Overheating protector refers to working when the water temperature is overheated. When the water temperature exceeds our set temperature, the overheat protector will cut off the water heater. If the overheat protector fails, when the water temperature reaches the peak, the continuous heating of the electric water heater is likely to cause explosion danger.

Matters needing attention in the use of water heater

1, when using the electric water heater, be sure to turn on the water source, and then turn on the power supply for heating after there is water flowing in the outlet pipe. Never turn on the power supply immediately before pouring cold water.

2. The faucets of electric water heaters often have backflow devices, and they are also marked with blue and red to indicate hot and cold faucets. When in use, turn the red faucet and hot water will flow out immediately. If the hot water temperature is too high, turn on the blue faucet at the same time to adjust the water quantity and water temperature.

3. When using the electric water heater, do not switch the water source frequently. This will cause the electric heating fittings to burn out due to insufficient water storage in the water tank. When adjusting the temperature, we must pay attention to storing water or feeding water in time. If the water storage is insufficient or the water intake is small, it will be very easy for the accessories to overheat and burn out for too long.

New electric water heaters are generally equipped with automatic power-off equipment. When the water is cut off or the water source is turned off, the water heater will automatically turn off, which will make the water heater safer.
