Currently, hardware stores have a large assortment water heaters. You can purchase budget models that are made in a classic design. They have round shape, which is why they seem quite bulky. To install such devices you need a lot of space. What about those who have very small apartments? Manufacturers also took care of this by producing (80 liters) vertical flat. As a rule, its depth is about 25 cm. Therefore, it can be placed in the bathroom, toilet and even in the kitchen.
Thanks to the beautiful design, such devices will fit perfectly into the interior. The weight of flat boilers is about 30 kg. If you use special fasteners, you can install them on any walls (concrete, plaster, wood). For example, Ariston ABS VLS QH 80. Its dimensions are: 1090 × 49 × 27 cm. Without water, it weighs 28 kg. The device is assembled in Russia. Equipped with two tanks (incoming and outgoing). There are three heating elements. Maximum temperature- 80 °C. Finished in silver with gray trim (top and bottom). The control panel is electronic.
Equipment for flat water heaters
The vertical flat storage water heater (80 liters) consists of almost the same parts as the classic models:
- Frame.
- Water containers. There are two of them in flat models.
- Thermal insulation. Located between the tanks and the body. Responsible for long-term preservation of water temperature.
- A heating element. The number of heating elements can vary from one to three.
- Control Panel. It is located either on the front side or at the bottom of the water heater.
- Thermostat and thermometer. The regulator allows you to set optimal temperature. You can change it at any time. The thermostat is a fuse against overheating, and it also turns off the heating element if the tank is empty. The thermometer shows the current water temperature.
- Bends. They provide the supply of cold water and the output of already heated water.
Flaws
Even the most expensive vertical flat storage water heater (80 liters) has some disadvantages. Let's look at them:
- Heat loss. Due to its specific shape, the thermal insulation layer is quite thin. This leads to rapid cooling of the water and, as a result, to increased energy consumption.
- Jumpers between internal tanks. Most often, leaks occur in places where welds are located. This leads to the formation of rust. Unfortunately, even stainless steel containers quickly fail.
- High price. Compared to classic models, flat ones cost several thousand more. It is also worth paying attention: purchasing spare parts and repairs will also be expensive.

For the average person, choosing a storage boiler is not the easiest task, especially if you don’t have any idea what kind of equipment it is and how it works. This article will tell you what water heaters are, the operating principles and parameters by which you should choose a boiler, and will consider some models of 50-liter storage water heaters.
A storage water heater is a convenient and reliable means of providing hot water to a city apartment, private house or cottage. A flat shape and relatively small capacity make it convenient to use. A water heater with a capacity of 50 liters will be an excellent option for single or elderly people, as well as small families.
How does a storage water heater work?
Essentially, a water heater is a large tank in which a heater (heater) is located. When you open the tap, hot water flows out and cold water comes in in its place. When the tank is completely filled with cold water, heating begins. Full The water does not heat up immediately and depends on the power of the heater. Naturally, the more powerful it is, the faster the water will heat up.
Water heaters with a volume of 50 liters can easily provide hot water to a cottage, apartment, house and even office. In this case, a clear advantage is the fact that connection does not require a dedicated power line and special skills. It is enough to insert the plug into a regular 220 W socket. Another undeniable advantage is the ability to connect two or more points simultaneously. That is, one boiler can simultaneously provide water for the shower and taps in the kitchen.
Instantaneous water heater design
The instantaneous water heater consists of the following components:
Selecting a storage water heater (50 liters)
Once it has become clear how the water heater works, you can move on to making a choice. To do this, you should know what you should first pay attention to when buying an electric flat water heater.
- Power. Typical home boilers have a power of one to three kilowatts. This indicator indicates the heating rate and energy costs.
- Heating element location. It can be directly in the water tank or “hidden”. The second option is preferable, since hidden heating element is not exposed to water, that is, it is not afraid of lime or salt deposits. The hidden heating element will definitely last longer.
- Material of the inner surface of the tank. There can be three options:
- enamel (short-lived);
- glass porcelain (service life 3 years);
- titanium coating (service life 10 years);
- Thermal insulation thickness. The greater the thickness, the less heat transfer. Less heat transfer means less energy consumption.
- Control system. Electronic board or regular thermostat. Electronic board has a more flexible temperature setting option and a heat maintenance system, and also looks more aesthetically pleasing. But such beauty and convenience have one drawback - a reverent attitude towards electricity. During power surges, the probability of failure of this particular unit is storage water heater very high.
- Type of location - horizontal or vertical.
- Volume. The best option for a small family is 50 liters. Although it all depends on the use.
- Company manufacturer.

Comparison of instantaneous and storage electric water heaters
Let's consider the advantages and disadvantages of storage and flow-through water heaters.
The advantages of instantaneous boilers include the possibility of instant use, compact size, low price and light weight. There are also a number of disadvantages: high electricity consumption, connection complexity, the need for a separate electrical line, providing water to only one point, and in the absence of electricity, use is impossible.
Advantages of hot water storage water heaters low energy costs, maintaining water for some time after a power outage, providing water to several points at the same time, ease of installation and low wiring requirements. Disadvantages include high price and big sizes in comparison with instantaneous boilers, as well as heating time.
Both devices are good, but use instantaneous water heater It is advisable in conditions where water is needed immediately and in small quantities, and storage is more for the constant supply of living quarters.
In many regions this has long become a habit. If there is no hot water all summer or even several weeks, the solution is obvious. You need to buy a boiler. An electric water heater provides additional comfort and allows you to not depend on public hot water supply systems.
The boiler maintains the required water temperature, while having a certain supply. On the Ukrainian market big choice boilers. But in order to choose the right boiler, you need to take into account many nuances.
What is a boiler
The water heater itself is a tank in which cold water It is heated to a predetermined temperature using an electric heating element - heating element.
There are two types of heating element: wet heating element - immersed in water, dry heating element - has no contact with water. Experts believe that the second option better than the first, since scale does not form on it, which means it will last longer. Dry heating element is located in special flasks and does not come into direct contact with water. Typically, dry heating element is recommended to be used when the water contains a lot of salts. In this case, the wet heating element will fail much earlier.
The type of heating element is not the only thing that affects how much a boiler costs. A dry heating element will cost more than a wet heating element. There are other parameters due to which the price difference between different types of boiler reaches several thousand hryvnia.
The boiler can be round or rectangular, narrow or wide. In general, rectangular models are more convenient. Narrow boiler - suitable for a niche or cabinet. In this case, a narrow boiler can be either rectangular or oval-round. Before you buy a boiler, you need to figure out where you will install it. Depending on this, you will have to choose a boiler.
How does a boiler work?
Once in the tank, the water is heated to the set temperature, after which the thermostat turns off the heater. The desired temperature can be set. In the most inexpensive and simple models, the exact value in degrees is not set on the panel - they are limited to symbolic images indicating the gradation from “cold” to “hot”. If the boiler is more expensive, then often the electronic control system already allows you to set the temperature with an accuracy of 1-2 degrees. Devices with the ability to program the heating temperature depending on time will cost even more.
If you for a long time If you didn’t use water, for example, you left for several days, and the boiler was not turned off, then it will independently heat the water when the temperature drops. To prevent the boiler from working independently and to avoid unnecessary energy consumption, it is better to turn off the water heater before leaving.
If the water cools down completely during your absence, then when you turn on the boiler, it will heat up for a couple of hours. The volume of the water heater also plays an important role here.
Volume and good wiring are an important point to consider before installing a boiler. Often, when choosing the volume of a water heater, they are based on the number of people living in the living space.
Boiler volumes vary from 10 liters (the smallest), they are often installed in the kitchen to wash dishes - up to 120. A boiler with a capacity of 1.5 - 2 kW - these are the models most often bought by Ukrainians, given that many high-rise buildings do not have very reliable power supply system. A boiler with a power of 1.5 kW and a volume of 80 liters will heat cold water in 3 hours. A 2 kW boiler will heat 80 liters in 2 hours. A 2 kWe boiler will heat a 50-liter tank in 1 hour.
Returning to the price: the larger the tank volume, the more expensive the boiler. Hence the question, do you need a boiler with a tank volume of 120 liters if you live together?
There are models that have two heating elements installed. This is a kind of insurance in situations where there are problems with using significant electrical power while simultaneously operating a boiler and, for example, washing machine or heater. Turning on another powerful consumer can lead to the circuit breaker being turned off. To prevent plugs from being knocked out due to high load, you can turn the boiler on in an economical mode when one heating element is running. The water will heat up slowly, but there will be no overload.
Installation
Theoretically, you can install the boiler correctly - connect it to the electrical network and connect it to the water pipe - yourself. But it’s better to contact a specialist. It often happens that the person who bought the boiler has the right to warranty service and free installation. The first thing you need to determine is the location for the boiler. Most often, it is installed on the wall of the bathroom or toilet. But here great importance has the weight of the device - after all, even an empty boiler often weighs about 25 kg. Add to this 50, 80 or even 120 kg of water. It is important to know that not every interior wall can support the weight of the boiler. When installing a water heater, it is advisable to use special steel anchors.
To properly install the boiler, professionals advise installing a separate socket. After all, an outlet is usually designed for a voltage of 220 V and a current of 10 A. If we multiply these values, we get 2,200 W or 2.2 kW: this is the output of a standard outlet. There are also 16 A sockets, their output can reach 3,520 W or 3.5 kW. If the outlet is 10-amp, in this case we can talk about the permissible power of about 2 kW. Hence, the power of the heating element in the boiler is approximately equal, be it 50- or 150-liter.
Installation costs about 600 UAH - plus 300-500 UAH for consumables.
- A 15-20 liter boiler without water is 10-13 kg, add the weight of water (15-20 kg) and the result is 25-30 kg of load on the wall;
- a 50 liter boiler weighs 17-20 kg empty and about 70 kg full;
- an 80-liter model weighing 20-22 kg can easily put 100 kg of additional load on the wall when fully filled with water;
- larger models with a volume of 120-150 l provide an even greater load - up to 150-180 kg.
If you have opted for a 100-liter boiler or larger, it is better to provide floor support for it. This could be a shelving unit, supports, or a cabinet with stops. Due to such support, most of the load will go to the stand, which will provide insurance for the fasteners.
Self-installation
First of all, you need to read the instructions. The installation of a water heater is always described there. Then you need to install a safety valve. This valve is installed on the cold water supply line (where cold water enters the boiler), cuts off the water supply when the boiler is filled and releases excess pressure when the water boils, which protects the boiler from exploding.
Installation of the valve is mandatory; during operation of the boiler, it may drip a little - this is normal operation. Carefully monitor the valve, clean its moving part from dirt and scale. This is the basis for the safety of the entire boiler system.
Be sure to pay attention to the electrical connection of the boiler. Perhaps in old apartment You will even have to transfer the wiring from the meter to the boiler socket. The boiler wire itself in 99% of cases should be 3-wire - taking into account grounding, which also needs to be checked in the outlet.
If you have old wiring and you are not sure about it, then it would be better to invite an electrician to make a separate line for the water heater or replace the wiring completely.
Problems in use
The boiler works on the principle of an electric kettle. That is, it tends to suffer from scale on the heating element. In Ukraine, hard water flows in taps, and this greatly reduces the service life of the device. To combat this problem, softening filters are often installed.
Another problem with boilers is corrosion. To combat it, anti-corrosion protection in the form of a magnesium anode rod is used. Such a rod takes the entire blow upon itself, gradually collapsing.
Any boiler is equipped with an “anti-corrosion anode”. This anode serves as a “magnet” for rust and active chemical elements, thus protecting the boiler tank and must be replaced after 1-2 years and, in fact, is a consumable item. Along with replacing the anode, it is advisable to clean the heating element from scale and flush the boiler tank. But even so, in order for the water heater to last longer, it is necessary every six months to invite a specialist who can assess the condition of the anode rod and heating element and clean them.
Sometimes the master decides to replace the heating element. This service is relatively inexpensive, in the range of 300-350 UAH. Compared to buying a new boiler, it is much cheaper. Often, having bought a water heater, people do not think about the need for prevention and maintenance. This saves both money and time. After all, buying a new boiler costs a pretty penny.
