How to choose a water heater. Electric water heater: отзывы

The lack of hot water in the apartment causes many problems. Everyone decides it in their own way. Some install a storage tank, while others prefer a running water heater, which will be discussed later.

General information

What is a water heater? This is an ordinary mixer, the dimensions of which are mute.

It contains a heating element, as well as other equipment that helps to ensure safe operation of the device. It can be distinguished from a conventional mixer by a wire that connects to the mains. The water heater can operate in two modes:

• The first mode is called "shutdown" (cold supply). The electrical part of the device is completely disconnected, and cold water comes from the tap.
• And the second one - hot water supply. With it, the electrical system switches on and, within seconds, heats the circulating liquid.

How can I change the temperature?

To adjust the temperature of the liquid, it is necessary to increase or decrease its head. To perform such a transition, a special lever is provided in the design of the water heater. Thus, you can adjust the desired temperature of the liquid to within one degree Celsius.

Also there are models where the regulator is located on the side of the case, which is much more convenient. Special electronics monitors the water temperature and independently reduces or increases it.

Benefits

The electric water heater has the following advantages:

1. Instant heating of water. Such devices are capable of heating in as little as 5 seconds. In addition, it is able to supply a sufficient amount of liquid. If other heaters are not able to fill the bath, then this model perfectly copes with the task.
2. The temperature does not get lost after the first use, but remains in the same parameters. This is very convenient, since you do not have to waste time adjusting the temperature.
3. The tap water heater fits perfectly into any interior, and the unknowing person does not guess about the functions of the mixer.
4. Democratic price. Its cost is in the range of five to ten thousand rubles. Compared with other models, the electric water heater is the most affordable in this respect.

Disadvantages of the device

The most important negative side is the high consumption of electricity, the price of which is increasing every year.

For an hour of work, the water heater uses 3 kW. Also worth noting is the low fluidity of the liquid. The most powerful unit is capable of heating 5 liters of water per minute. For example, the capacity of the gas column is 2 times greater. The power of the described device is sufficient for everyday needs.

Safety features

The tap-water heater combined such incompatible things as liquid and electric current. This combination can lead to electrical injuries. That is why all devices have the maximum degree of protection, which includes such elements:

1. RCD. It is designed to protect a person from electric shock with mechanical damage to the enclosure or electrical components of the device. Another function is to protect against voltage surges.
2. Overheat protection sensor. If the liquid reaches a temperature of + 60 ° C, the sensor is triggered and the device turns off. The work is restored independently after lowering the temperature.
3. Dry protection switch. It happens that in the water supply system either insufficient or excessive head for water supply. In this case, the sensor switches off the heating device.
4. To protect against water hammering a special silicone damper is installed.
5. All electrical stuffing is protected by waterproof material.

"Delimano", water heater

The crane of this company is one of the most popular. In order to heat the water for the shower, as a rule, devices of medium power are sufficient. But for people who love to take a bath, it will be necessary to install an additional appliance in the kitchen to have enough power. Heating of water to 60 ° C is achieved in just a minute.

The most important advantage is ease of use. According to many reviews, it was not difficult for users to install a water heater. A huge drawback is the consumption of a large amount of energy. Therefore, many users constantly knock out traffic jams, and you have to install more powerful ones. Many people do not like that when switching on there is a thin stream of hot water, and when the pressure increases, it becomes lukewarm.

Therefore, it is difficult to type any large capacity. Crane-water heater, the testimonials of which indicate that not everyone can install the device, also note the frequent frequent breakdown of the electrical element.

Water-heater

By its technical characteristics, it does not differ from the previous version, but it has its own merits. The crane "Aquatherm" is equipped with an aerator. It cleans the liquid of coarse impurities. Installed in the kitchen and bathroom. In addition, the tap water heater "Aquatherm" is produced in different colors, which makes it possible to perfectly fit it into any interior. It operates from the usual consumer electrical network with a voltage of 220 V. It is able to heat water up to 60 ºС for a short period of time such a faucet-water heater.

Reviews about it were divided, because for intensive exploitation, for example, in a large family, it is not very suitable.

A significant disadvantage, as with other devices, is a large energy consumption. For an hour of work is spent 3 kW. Prices are rising every year. Therefore, it is expensive to use it for permanent household needs. But he will be an indispensable assistant in the country or in a country house, where there is not always an opportunity to put a boiler. In addition, many can not install such equipment, and it is necessary to call a specialist, and this is an extra waste of money.

Installation

The electric water heater is installed in the same way as a conventional mixer, but there are differences. Firstly, it is added only to cold water supply. Although there are such models where the connection is combined. Secondly, it is necessary to conduct a separate electrical cable with a consumer voltage of 220 V. Since the device is electrical, it is necessary to establish a ground.

Conclusion

So, we found out what this household appliance is. Electric water heater is an excellent assistant not only in the apartment, but also in the country or in a country house. It has a number of undeniable advantages, among which we should note the rapid heating of the required amount of water and the regulation of the desired temperature of the liquid. All models are made in different colors, which makes it possible to fit them into any interior. The flowing water heater does not harm the human body, since it has a reliable protection system. The cost of such equipment varies from 5000 to 10,000 rubles, depending on the capacity. The only drawback is the large energy consumption. However, judging by the undeniable advantages, this shortcoming can be forgiven.

The most important negative side is the high consumption of electricity, the price of which is increasing every year.
