Electric water heaters

The main components of an electric water heater

Join us to learn more about each of the components of the electric water heater

Water reservoir or source

One of the most important parts of an electric water heater is its tank, which is made with different capacities and is generally made of resistant metal or steel sheets. Since the water is inside the main source, the position of the element and a part of the thermostat are also placed in it. The tank contains 4 important pipes:

Inlet pipe: to transfer cold water into the source
Outlet pipe: to transfer the spa to the bathroom or sink, sanitary purposes, etc.
Drain valve: When we need to drain all the water inside the water heater due to repair or relocation, we use the drain valve.
Safety valve: If the water inside the water heater gets too hot, it has the task of transferring extra hot water to the outside to reduce the high temperature of the water heater, which of course has a very important safety and security aspect in closed and pressurized sources.

An electric water heater element

Its main task is to convert electrical energy into thermal energy and increase the temperature of source water, and its material is aluminum, nickel or chrome. And also to prevent electrical connections and disruption of this part, it is rolled in porcelain powder or ceramic soil. In addition to this, it has stainless steel plating to increase its resistance to abrasion and rust.

For its strength and beauty, it is painted in different ways and it is made of steel sheets.

Thermostat

The task of the thermostat is to automatically control the source water temperature, which is another important part of the electric water heater. The thermostat works automatically, which itself has different parts.

news lamp

As its name suggests, it informs the status and performance of the element or heater. When there is a malfunction in the electric water heater. We will see a malfunction of the new lamp. This piece of electric water heater is installed in its electric circuit and parallel to the heater. The warning lamp works simultaneously with the element being turned on or off, and the working voltage of these lamps is 220 volts.

Interconnecting wires and fireproof insulation

In houses where the lines are protected separately, and it is also better in all houses for an electric water heater, an independent line should be drawn from the electricity input of the house and this line should be protected with a fuse of at least 15 amps. The minimum cross-section of the wire in the water heater should be 1.5. Because the electricity consumption of the electric water heater is high. Also, when choosing a plug, attention should be paid to the electricity consumption of the water heater.

Where is the electric water heater used the most

Among the applications of electric water heater, the following can be mentioned.

Use of electric water heater in villas

One of the most important uses of electric water heaters is villas. Due to the fact that villas and garden houses are usually far from the urban area, it is not possible for them to access city gas, so to provide the required hot water, they are forced to use another source to generate heat, and the most accessible of them is electricity. be

Use of electric water heater in condos

Due to the fact that the connexions have the ability to move, it is not possible to connect them to city gas and they do not have the possibility of gas piping. In addition, sheds are generally located in workshops or places that are far from urban facilities. Therefore, electric water heaters are an ideal option for use in it.

Use of electric water heaters in villages

Because some villages in the country do not have gas piping, the use of electric water heaters can be the best option for providing sanitary and appropriate hot water.

Advantages of using an electric water heater

The main advantage that can be attributed to this category of water heaters is that they can be used in places where gas is difficult to access. Among other things, we can mention the following:

The silence of the electric water heater due to the use of electricity
No need to install an electric water heater chimney
Cleanliness and reducing the risks of environmental pollution
Ease of installation and low cost for water heater maintenance
Having a longer life because there is no flame in the electric water heater
Easy installation without the need for gas piping and chimney
Reducing the volume of gas piping in buildings because electricity is used
It does not need oxygen to consume energy and heat water
Using an electric water heater inside the building makes the units independent from each other

Disadvantages of electric water heater

Electricity consumption: One of the disadvantages of an electric water heater is that its electricity consumption is relatively high in general, which of course will not be very high due to the fact that it is not in constant use and the occasional use of the electric water heater. The absolute dependence of the electric water heater on electricity is another difference between the electric water heater and the gas water heater.
Water leakage: Water leakage is one of the possible problems of water heaters. Due to over-pressurization, overheating, a damaged valve, a leak from an overhead or adjacent piping connection, loose heating element bolts and nuts, a damaged gasket, or a failed temperature valve in the water tank. In this case, you can tighten the loose screws with a wrench. If the water dripping is due to the decay of the tank, repairing the tank will not solve the problem, and the only solution is to replace the tank. Water tanks can leak due to corrosion or other issues such as improper O-rings. Consider replacing an o-ring if needed or have the tank serviced.
Rust: Rust (metal rust) is one of the water heater problems that can be caused by the corrosion of the tank or an anode rod. If the outgoing water has an egg-like smell, you should replace the rod in the tank and disinfect it by purifying the water, and if the anode rod is damaged, replace it with a magnesium anode rod. Also, a damaged and decaying anode rod can release hydrogen. To solve this problem, first, wash the water heater. Then wash the tank and pipes for two hours with a solution containing 2 cups of 3% hydrogen peroxide and 40 cups of tap water. If the smell persists, replace the damaged anode with a new zinc alloy anode.
Sediment: The existence of such a problem is due to the water heater getting sediment and also to the boiling of the water inside the tank. To solve this problem, you must first wash the tank and clean it completely from sediment, if the problem still persists after doing all these things, you must replace the water heater tank.

Important points to consider when buying an electric water heater

To buy an electric water heater, different points should be considered. Also, paying attention to these points will make the chosen device have the performance you want, in addition to a better purchase. These important factors are:

Capacity and size of water heater

In models that include a tank, the allowed capacity should be between 50 and 80 liters, and for large families, products with a larger capacity are definitely considered. Also, in-wall models, the size of the desired product should be considered. And naturally, the bigger its size, the more it can heat the water in a minute. As a result, to choose the capacity and size of the water heater, one should pay attention to the number of family members.

the amount of energy consumption

Considering that the cost of various energy sources, including electricity and gas, is very high. When buying a water heater, you should consider the energy consumption of the product as one of your criteria. Today, most household appliances, especially heating and cooling appliances, are tested in reliable laboratories in terms of energy consumption and have their own energy consumption grade. To buy the best water heater, you should choose a model that has an A grade.

Durability and quality of the water heater

The next important thing that you need to buy a good water heater is its standards and certifications, which you should pay special attention to because these things show the high quality of the product, which makes it last longer. One of the important advantages of buying a standard water heater is that it requires fewer repairs, and keep in mind that even if you pay a high price for a standard water heater, you will be sure that it will work for several years and the cost of repairs will be lower.

Electric water heater safety

In order to be sure of the safety of a water heater, you should pay special attention to things such as: having a safety valve, an automatic shut-off system, a safety valve, and things like that. It is better if you do not have expertise in these matters, be sure to get from experts in Damatajhiz.
