With the development of suburban real estate construction, most people were drawn closer to nature and fresh air. But private economy implies self-sufficiency in the products of civilization, including hot water. Although such a need may be relevant in city apartments of the old fund or during the summer period when hot water is turned off. For this reason, interest in water heaters and their demand does not surprise anyone. But we will tell you how not to make a mistake when choosing in this article, which will also provide a list of the best appliances for heating water from the largest Swedish company Electrolux, which offers a wide range of household appliances in the middle price category.

There are a wide variety of water heaters on the market. The main difference is the type of heating element, which divides them into several types. In one case, the heating method occurs immediately upon supply using the built-in heating element. Such devices are called instantaneous water heaters or columns. The second option contains a tank in which the heating element is located. This will already be a storage water heater or boiler.
The characteristics of these devices are different, therefore, before purchasing, it is necessary to indicate the selection criteria, and understand which device will satisfy all the needs for water supply.
Of course, in terms of its functionality, the accumulative heating method is more attractive. It is designed for a larger number of consumers, less demanding on unstable water pressure in pipes and voltage in electrical networks.
But flow also has its advantages. At a price they are much cheaper and therefore, with rare use, for example, on weekends in a summer cottage, it is perfect. Another plus is its small size and, unlike storage tanks, it does not take up much space.
What you should also pay attention to, in addition to such fundamental differences, is that each type has models with different characteristics.
Water heaters can work from a network or from gas.
Gas appliances are a more economical option, but their installation must be considered carefully to avoid any risk of gas leakage. It will not be superfluous if the purchased device is with the gas control function. These budget popular models, according to buyers, have good characteristics, and they are ideal for rooms where gas is already installed.
An electric water heater, of course, is much more expensive, but also safer, although when connecting it, you need to take the electrical wiring with all responsibility and correctly calculate the load.
Separately, we can say about devices with indirect and combined heating. Indirect heats water using a heating boiler and a steam or water heat exchanger.
Combined - this is a storage-type heater that combines work both from a central or individual heating system, and from an electrical network or main gas. In its design, it includes an electric heating element, a spiral heat exchanger connected to a heating boiler. This multifunctional option, a kind of combination of indirect heating with an electric heating element.
The power of storage electrical devices varies from 1 kW to 6 kW, and for flow devices from 3 kW to 27 kW. This is not so much compared to gas ones, which are capable of delivering up to 25 kW.
To fully provide hot water, it is better to purchase equipment of at least 8 kW, but as mentioned above: in this case, you should already pay attention to the electrical wiring. With a standard one, it is better to purchase a device with a power of no more than 2 kW.
The division goes into non-pressure and pressure ones, which, as the name implies, either supply water under pressure or without it. Pressure pumps have good performance and can provide several points of water supply at the same time. Non-pressure are less efficient and are suitable for one consumer. But they are safe and have a long service life.
The material from which the tank is made must first of all be environmentally friendly, not corrode and keep the water hot for a long time. Smaller models use polypropylene and copper, but enameled steel is still the best option.
The volume of the tank is calculated from the needs of the buyer. For household needs, 10-15 liters are enough, 50 liters may be required to take a shower, and 80 liters to take a bath. It is better for a large family to purchase a gas or electric boiler with a capacity of 80-150 liters.
According to the type of installation, water heaters are divided into floor and wall.
Wall mounting is a more convenient option. Such devices usually do not exceed 100 liters, the mass of which with water is 130 kg. But even with a smaller volume, it is necessary to take into account the reliability of the walls. Flowing water heaters in most cases have a wall-mounted installation.
Appliances with a volume of more than 100 liters are usually located on the floor.
