Comfort plays an important role in human life, and it is difficult to imagine a modern house without hot water. Therefore, various water heaters have been developed, powered by electricity and gas. In country houses not always it is possible to lay a gas main, and in apartments sometimes it is not allowed to connect such a heater, or it is associated with tedious project approval procedures. That is why most homeowners connect electric boilers, in this article we will discuss with you how to choose the right electric boiler, how many liters of heated water you need and which manufacturer you should pay attention to.
Types of electric boilers
Boilers manufactured different firms, have different design and power, but there are no differences in the principle of operation, as well as in the device circuit. But it should be noted that applying the new design — color, control panel placement, or product shape, manufacturers charge higher prices, and they can vary by a factor of two or even four. And sometimes the cost of these water heaters maybe not even directly depend on the installed components and the build quality of the device.
To decide on the choice of the desired model, you need at least would briefly know the device of this electrical device and its characteristics. Based on them, it will be possible to make the right choice that will fully satisfy the needs of the consumer.

How is the boiler set up?
Schematic diagram of the boiler device
The main element of such a water heater is an electric heating element (heating element). TEN is inside containers with water, and its functioning directly depends on how the thermostat (thermostat) is set. This device controls the heating of water to a set temperature, which varies between 35—90 degrees. When the temperature set on the thermostat is reached, the automation is activated and the heating element is turned off. When the water cools down, also before certain limit, the boiler is switched on again and the process is resumed.
It is important for the good operation of the boiler and the long-term maintenance of the required temperature of the thermal insulation material. Insulation pad (polystyrene or made of mineral wool), which has certain form, is located around a metal tank, on which a decorative case with a control panel is put on top.
The capacity of water heaters is usually up to 2 kW. For their correct operation, without overloading the general network, it is rational to draw a separate line from the device accounting electricity consumption.
Water heating occurs gradually, so the power heating element must comply volume tank — then in German there will always be the right amount of heated water, the temperature that is set. To do not overpay for electricity, it is necessary to operate the water heater at a moderate temperature, those. set the thermostat to medium power, to water heating was carried out slowly, during certain time.
Determine the amount of water you need in the tank
Choosing volume tank, you need to rely on the average amount of water that is consumed in your family. The consumption will directly depend on the following criteria: the number of devices that use heated water, the number of residents living in a private house or apartment, and the number of water intake points.
This table clearly shows the approximate consumption of heated water per person, depending on the type her consumption:.
Average consumption of water heated in the boiler
How can you calculate the total volume necessary water heated to a temperature of 60 degrees, which is considered the most optimal and economical in terms of energy consumption?
Mostly, while taking a shower or bath, a person is accustomed to adjusting the water temperature to about 36—40 degrees, as it is the most comfortable for the skin. Mixing 60 degree cold water gives decline her consumption.
For example, you can calculate the cost for 3 people as follows:
Morning procedures: washing + shower + washing dishes — (8 + 25) × 3 + 14 \u003d 113 liters. It follows from this that a boiler with volume water in 120 liters, to do without additional heating.
Manufacturers produce tanks with volumes in 5 and 10, 30 and 50, 80,100, 120 liters. There are boilers and large volumes, but they are installed to heat water for several families or for the whole entrance of a multi-storey building. If the family is large, then you can find a way out and install two boilers — one for the bathroom and one for the kitchen. Otherwise, a 120-liter boiler will not be enough, and unpleasant situations are possible when someone will feel a shortage of heated water, and he have to long wait for the next heat containers.
Value for money, how to choose the golden mean?
Based on the foregoing, it is clear that the boilers do not particularly differ in internal design, and do not have significant differences in the fundamental device. The difference in cost is determined mainly by reliability and the quality of thermal insulation, components, metal from which it is made capacity, and the duration of the heating heating element — it is the most expensive element of the water heater.
The most affordable are products made in Turkey.and China, and Turkishmanufacturers , mostly, use containers and heating elements of Chinese companies.

They can be called quite high-quality, but the durability of products and the ability to do without repair for a long time are doubtful.

German and Italian boilers — larger in size due to the use of a thicker layer of heat-insulating material. Some firms have achieved check thickness of the insulator that even the daily cooling of water — minimum. Thus, a tank heated to the required temperature will lose only 5—6 degrees, which is almost imperceptible when using.

When choosing a boiler, you should also consider the amount of free space on the wall where it is supposed to be hung. The water heater can be located in one of the bathrooms — toilet or bathroom. For ensure hot water for household needs, it can be placed in the kitchen.
To save space, especially for small apartments with a minimum footage and not too high ceilings, you can choose a boiler that has a horizontal placement and is installed right under the ceiling.

boilers, mostly, do not differ in a variety of designs, but are produced in several colors and shapes. You can always choose the one that is more fit to the interior of the room.
The classification of water heaters, the form of their possible execution and the features of the device are detailed in the video below.

Having visited an electrical appliance store, you can make a choice on the spot by reading the instruction manual, as well as consulting with a sales assistant.
