A water heater is a water tank with an electrical heating system with a resistance and a thermostat. Its insulated tank allows you to keep the water temperature constant. A water heater consists of a ceramic vessel protected against corrosion. An injection of foam allows insulation between the tank and the outer shell. The tank is equipped with a magnesium or titanium anti-corrosion anode.

The tank is still under pressure. By thermal, the hot water is located in the upper part of the heater, from where it is extracted. The cold water that replaces it reaches the bottom of the heater, gradually rising as it heats up.

The heating of the water can be continuous and regulated by a thermostat, or only during peak hours, to benefit from electricity prices lowered by approximately 40%. Silent, it does not generate combustion, the electric water heater can be installed anywhere in the house: in a cabinet under the stairs, on the ceiling (for horizontal models). Hot water is always available and always at the same temperature (within the limits of storage capacity). Reliable, your machine is robust and has a useful life of 12 to 15 years or more.

Maintenance

The heater is a reliable one whose maintenance is easy. Operate the security group once a month.

If your water is particularly hard or acid, it is possible for a professional to periodically check the condition of the anode and the electrical resistance, depending on the model chosen, and ask you to empty the hot water (immersion). Your instrument generally does not require adjustment or monitoring; it works automatically.

The different types of electric water heaters

An electric water heater consists of a tank (or tank) and a heating element, which in turn includes an electric resistance, and a thermostat ensures the temperature setting. The reserve tank is protected against corrosion and against heat loss.

There are two types of resistance:

• Immersion heaters: the resistance is directly in contact with the water. Allows rapid heating of the total stored water.
• Soapstone: the heating element is inserted into a sleeve and the enamel is not in direct contact with the water. This system has the advantage of protecting the resistance against the risk of limescale. In case of verification, it means that you do not need to empty your tank.

The water heater operates on two principles

The tank is always full – hot water is used immediately replaced by an equal volume of cold water.

The hot water temperature is kept constant until the reserve is depleted. Due to its lower density, it remains accumulated in the upper tank without mixing with the cold water.
