Comfort and convenience are the criteria that should be met by the housing of a modern person. Residents of apartment buildings often have to deal with interruptions in the supply of hot water, which causes inconvenience and discomfort. If you have such domestic problems, water is supplied with restrictions or is completely absent, and you really need a backup source of hot water, then you should think about buying a water heater.
Such devices are becoming popular and in demand every year. By purchasing a water heater, the owners of private houses and apartments will save themselves from a number of inconveniences and ensure their comfort in everyday life.Today, the assortment of such units will pleasantly surprise, store shelves are represented by various water heaters, among which you need to be able to choose the right and suitable one.

A water heater or boiler is a unit due to which water is heated to a certain temperature.
Water heaters can be divided into:
The first version of the device is a system for storing hot water in a tank. The units are suitable not only for heating water, but also for supplying it to satisfy domestic needs. Water heaters of this type have a storage tank. The water is heated thanks to a heat exchanger or an electric heating element. There are models in which these two water heating elements are installed simultaneously.
Water heaters of this type are popular and in demand, this is due to the fact that they can be connected to a regular power outlet, hot water keeps the temperature for a long time due to insulation, the device can supply water to several points, the choice of such heaters is diverse.
Speaking of the minuses, you can indicate the dimensions of the device, they often take up space in the room, which is not always convenient, in addition, when carrying out work on its installation, it is seriously necessary to approach the choice of unit mounts.
A storage-type device consumes electricity even when it does not heat, but maintains the temperature of the water.
Instantaneous water heaters do not store water. When using this device, water is heated at the time of its supply. Within one minute, using such a water heater, you can get from five to twelve liters of water.
In flow-through water heaters, cold water flows through the water supply and, passing through electric heating elements, is brought to a certain temperature.
On such models, there are sensors that show the flow, and thanks to which the selection of the required number of heating elements is controlled. In the event of an increase in the water flow, a larger number of heating elements are activated, therefore, by reducing the water flow, the amount of work of the heating elements also decreases. This operation of the device can significantly reduce the consumption of electricity, which is used when heating water.
The devices are protected from overheating, the protection is triggered when a high (limiting) temperature is reached in order to prevent burns.
Both types of water heaters also have high pressure protection, which eliminates mechanical damage to devices in the event of surges, and this function also prevents water from boiling.
In some models of flow-through units, electronic control is used, and the necessary information is reflected on the display. It informs about the water temperature, its consumption, as well as the power of the heating elements.
Some water heaters may have a light indication that warns of exceeding the temperature limit. Most advanced devices have a remote control.
Speaking about the advantages of such models, the following should be highlighted:
The negative point of flow type water heaters is that they are distinguished by high power consumption rates. When installing it, it is necessary to carry out work on laying an additional cable of higher power. One simple and useful advice: when purchasing such a device, make sure that the electrical wiring is reliable and only then connect it to the network.
Popular flow-through water heaters include:
This unit is suitable for small needs for hot water, they do not take up much space, are compact, and are convenient to use.
According to the type of heating, units for heating water are subdivided into:
Appliances with an indirect type of heating are suitable for obtaining hot water to meet domestic needs in apartment buildings, private housing construction, cottages and country houses, as well as to meet the needs of industrial and commercial facilities. Such water heaters can be used with other heating sources, which can be a gas or solid fuel boiler, a solar system, as well as condensing or heat pumps.
The operation of the unit is that the water is heated in a spiral, and then it transfers heat to the water, which is in the tank of the water heater. Water heaters of this type do not have their own heat source; they can work in the heating system together with a boiler or solar system.
Speaking about the positive qualities of such water heaters, one can single out the volume of heated water, which can reach from 60 liters to 2000 liters of hot water. Water heaters of this type do not consume electricity, but borrow it from the heating device, thus, the device is economical and profitable.
Combined water heating units are similar to indirect heating devices. In such devices, in addition to the heat exchanger, there is an additional heating source - an electric heating element, which makes it possible to heat water even when the device is disconnected from the main heat source. Combined water heaters are very convenient, they act as a flexible tool in the heating system to obtain hot water.
Storage water heaters, in addition to their main purpose, also accumulate hot water reserves. In such models there is no heat exchanger, the heating process is provided by electric heating elements. It is these units that have an electric type of heating. Depending on the model, the water heaters are equipped with different models of heating elements. Among the popular and demanded models are water heaters, equipped with a "dry" type of heating elements. This type of heating element does not come into contact with water, it is reliably and firmly insulated with a special flask. Since the heating element does not have contact with water, this sufficiently increases the service life of not only the heating element, but the water heater.
An electric type water heater can heat water up to a temperature of 75 degrees, after which the boiler maintains the water temperature.
The process of heating the water is gradual, the water heater does not need a high power of electricity, you can safely connect the device to the general wiring system in an apartment or a private house.
Today, on the market for this group of goods, you can purchase models of water heaters from 100 to 200 liters.
When buying a heating unit, it is important to consider its technical characteristics, such as:
In addition, it is necessary to consider number of peoplewho plan to use hot water from a water heater. Water standards for each person and meeting household needs are different.
For example, if three people live in an apartment who prefer daily "shower" procedures, then a device for 50 liters of water will satisfy the needs, which can heat the water to 90 degrees for two hours. If family members prefer to take hot baths, then the volume of the boiler should be larger, from 80 to 100 liters.
Also, when choosing a device, pay attention to heating elements and cover inside the boiler, the presence of a thermostat. Choose an economical and efficient device.
Storage water heaters do not consume energy, except for devices with an electric heating element. The power of such a device is calculated based on the size of the unit's heat exchanger area, and the larger it is, the more volumes of hot water can be obtained. Consequently, the heater must also meet the parameters of the water heater. In the case of installing a single-circuit boiler with a capacity of 12 to 24 kW, it is necessary to install a water heater in the heating system with a capacity of at least 24 kW. It is forbidden to use a boiler with a heating element with a power lower than the boiler power, since it is possible that the heat exchanger of the water heater may overheat.
If the water heater is equipped with an electric type of heating elements, it is easier to calculate the power, since it depends on the power of the heating element. For example, a water heater, the power of which is 2 kW, will consume 2 kW or 2000W of electricity for one hour of operation.
Another not unimportant criterion when choosing a water heater is time, for which the device can heat water to the required temperature. Therefore, it is important to read the instructions, as a rule, manufacturers indicate the time for heating water in hours or minutes.
Today the market for this group of goods is represented by models of water heaters with one or two heat exchangers. Appliances with one heat exchanger are operated by a heating boiler. In water heaters with two heat exchangers, this element is located in the lower part of the tank and is the main one, and the heat exchanger located in the upper part is additional.
An indicator such as recirculation, is important when buying a water heater, since many of us have come across such a feature as waiting for cold water to drain, and after the start of water supply of a higher temperature. It is difficult to call it a problem, but recirculation helps to reduce water consumption.
Recirculation can be ensured if the device has a hole for installing a branch pipe. In addition, a circulation pump is required. Its task is to supply water in the opposite direction to the water heater. Thanks to this process, it is possible to maintain a constant temperature in the system. If the water in the system cools down, the pump starts to work, which supplies water to the water heater, and water of higher temperatures begins to flow into the system, the consumer, opening the tap, can use hot water without delay.
Some models of water heaters have an additional connector located on the side of the device under a plastic cover. Such an element allows you to add, if necessary, an additional electric water heater of the required power. In addition, through such a connector, you can carry out cleaning and maintenance work on the unit. Proper and complete care is important for such household appliances, since sediment and scale can form on the inner walls of the tank. The amount of scale depends on the hardness of the water and its heating temperature. In addition to these troubles, various dangerous microorganisms and bacteria can appear and multiply inside the water heater. Therefore, it is important to carry out regular preventive maintenance not only for the full operation of the device and its long service life, but also for human health.
Another criterion by which water heating devices can be divided is their appearance and installation method... This gradation is also another selection criterion:
Water heaters such as a boiler can be mounted both vertically and horizontally. But when buying, consider the place where you plan to secure it. The device connections should be at the bottom or at the top. A water heating unit for a small volume of water often has a vertical installation. Therefore, when choosing a boiler model and designating a place for its placement, give preference to a device with a certain type of pipe. When purchasing a water heater that has a volume of more than thirty liters, the choice should be stopped on models with a bottom connection of nozzles. Such units will not cause problems during maintenance, and such an arrangement of the nozzles will allow water to be drained from the tank without dismantling the water heater.
If you cannot decide on the appropriate volume of a water heater, then there are several recommendations:
In addition to technical characteristics, it is necessary to take into account the state of the electrical wiring in an apartment or house, since devices with a power of more than 2.5 kW will have too much load.
Form of heating units can be barrel-shaped, cylindrical (slim), or rectangular. Slim devices can provide a large amount of hot water, such units save space, they are rational and convenient. Rectangular water heaters take up much less space than cylindrical devices, they are installed under the sink or kitchen sink, as well as in the bedside tables of kitchen sets.
Water heater material
You will not have to get confused here in the choice, since they are made of steel or stainless metal. The steel tank is covered with enamel, it is more affordable than the models made of stainless steel. But it is important to know that stainless steel water heaters are resistant to corrosion and have a longer service life. However, the units also have disadvantages, the walls of the tank are thin, therefore, they are too sensitive to shocks, sudden changes in water pressure in the system.
Today, water heaters are often protected with an anode of magnesium or zinc, which oxidation ensures the durability of the water heater metal.
