A water heater is a water tank with an electrical heating system with a resistance and a thermostat. It’s isolation tank allows it to keep water temperature constant. A water heater consists of a ceramic vessel protected from corrosion. A foam injection allows isolation between the tank and the outer envelope. The tank is equipped with a magnesium anode corrosion or titanium.
The tank is still under pressure. By thermal, hot water is at the top of the heater, where it is drawn. The cold water that replaces it reaches the bottom of the heater, and raises gradually as that it heats.
The water heating may be continuous, and regulated by a thermostat, or only done during peak hours, to benefit from lower electricity prices by about 40%. Silent, does not generate combustion, electric water heater can be installed anywhere in your home: in a cupboard under the stairs, a 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 solid and has a lifespan of 12 to 15 years or more.
The heater is a reliable whose maintenance is easy. Operate once a month the security group.
If your water is particularly hard or acidic, checked periodically by a professional state of the anode and the electrical resistance, depending on the model chosen, you may be asked to empty your hot water (immersion). Generally your instrument requires no adjustment or monitoring; it works automatically.
The different types of electric water heater
An electric water heater consists of a tank (or tank) and a heating element, which itself comprises electrical resistance and a thermostat ensures the temperature setting. The reservoir tank is protected against corrosion and against heat loss.
There are two types of resistance:
• Immersion heaters: the resistance is directly in contact with water. It allows a fast heating of the total water stored.
• The soapstone: the heating element is inserted in a sleeve and enamel is not in direct contact with water. This system has the advantage of protecting the resistance risk of fouling due to lime scale. In case of verification, it means you do not need to empty your tank.
The water heater operates under two principles
The tank is always full: hot water is used immediately replaced by an equal volume of cold water.
The hot water temperature remains constant until depletion of the reserve. Because of its lower density, it remains accumulated on the upper reservoir without mixing with cold water.
