For the common man the choice storage boiler not the best simple task, especially if you have no idea what this technique 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 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 become 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 opening the tap hot water pours out, and cold water comes in its place. When the tank is completely full 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 in the storage water heater is very high.
- Type of location - horizontal or vertical.
- Volume. The best option for a small family - 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.
