Hot water is one of the main needs in residential buildings, commercial units and many industrial environments. In electric water heaters, a part called element is responsible for converting electrical energy into heat and heating water. The correct operation of this part has a direct effect on the speed of water heating, energy consumption and the efficiency of the device.
The electric element of the water heater is a thermal resistance that generates heat by passing the electric current and transfers it to the water inside the tank or thermal chamber. This part usually consists of resistance wire, electrical insulation and metal sheath resistant to heat and water contact conditions.
Besides the element, the thermostat also plays an important role. The thermostat controls the water temperature and when the temperature reaches the set range, it cuts off the electricity flow to the element. When the water temperature drops, the system is activated again to heat the water.
For this reason, choosing the right element is not only limited to its power, and the dimensions, sheath material, type of connection and its compatibility with the water heater should also be checked.
The main components of the electric element of the water heater
In order to make the right choice and better understand the performance of this part, it is important to know its components.
1. resistance wire
The resistance wire is the main part of heat production. This wire is usually made of resistant alloys such as nichrome, and by passing electric current, it converts electrical energy into heat.
2. Metal sheath
The outer shell protects the inner parts and transfers heat to the water. The material of this part can be selected from copper, steel or other alloys according to the usage conditions.
3. Internal insulation
In the construction of the element, heat-resistant electrical insulation is used so that the resistance wire is separated from the metal sheath and unwanted current does not transfer to the body.
4. Flange or threaded part
This part is used to install and connect the element to the water heater tank. The type of connection must match the bushing and installation location of the device.
5. The location of the thermostat
In many models, a compartment is considered for the placement of the thermostat rod or sensor to control the water temperature with proper accuracy.
Types of electric water heater elements and their differences
Not all water heaters use the same type of element. The difference in the design of the tank, the capacity of the device, the place of installation and the thermal power has made different models of this product to be produced.
