Maintaining your electric water heater ensures you use its full calorific potential, while having energy efficient operation. It consists of routine safety and purging operations as well as more complex limestone removal procedures. Find more articles on the theme: Work quotes for a water heater installation

Routine safety maintenance

In order to ensure that your equipment continues to exhibit high operating safety, it is strongly recommended to check the safety valve of your electric water heater every year. Generally located at the base of the cumulus, this wheel allows emergency evacuation of a possible overflow of hot water. It is important that it opens easily and that the contents of your tank flow quickly, without encountering any obstacle. Bring a basin to collect the water, activate the lever and close it quickly. The flow should immediately stop, without additional drip. Otherwise, the valve must be replaced. When doing this, remember to keep at least one arm away from the water heater due to the possible pressurized outlet of the hot liquid.

Regular purging of impurities

Despite its quality, the cold water entering your cumulus contains impurities, which will accumulate in the tank. These elements translate into less efficient operation of your equipment and additional electrical consumption. Regular emptying allows you to eliminate them. Before you begin, turn off the power at the circuit breaker and your general water supply. Also close the inlet valve on your water heater. You then have two solutions depending on the model of your cumulus. If a drain valve exists, activate it after placing a bucket under the tank: speed up the process by opening the hot water taps of your sanitary facilities. If there is a dedicated drain valve, connect it to a garden hose, the other end of which dips into a sink or sink.

Descaling often necessary

Among the impurities, limestone proves to be the most annoying for your water heater: it gradually solidifies, especially on resistance, resulting in lower energy efficiency. It is recommended to remove the lime in your tank every 2 years. At the end of a drain, unscrew the cover of the electrical box and disconnect the ground wire associated with the thermostat. Firmly grasp the latter and pull it down, keeping it straight until it comes out completely, to avoid damaging its probe or irreparably bending it. Then dismantle the inspection hatch to access the tank and clean the accumulated lime with a cloth. Make sure to gently remove the sediment on the resistance.
