Water heater accumulative - what firm is better?

In cities, hot water is periodically turned off, which leads to a lot of inconvenience. That is why the issue of installing a domestic water heater is so acute. But they all differ - not only in terms of technical characteristics, device, principle of operation and speed of operation, but also reliability, durability. And an important role in the last two moments is played by the manufacturer. That is why, if it is the goal to choose a storage water heater - which firm is better, you simply have to study it in advance. This will help you not only to pick up a really high-quality unit, but also to spend less time to buy it, because the assortment of models under consideration will narrow down at once.

DHW storage heaters

Before you find out which storage water heater is best, consider what it consists of. Its main elements are:

• Bak;
• with heating element;
• Protection System;
• Control System;
• Enclosure.

Most often, high-quality stainless steel is used to make the tank. In expensive models, the tank can be made of copper. Very rare phenomenon - plastic containers.

Corrosion protection is carried out with the help of special protective equipment:

• Steklofarfora;
• Enamels;
• Silicon-organic compounds.

Important! The service life depends on the quality of the tank, the greater its thickness - the longer it will be in operation. In this case, the expansion of the metal is not so strong that it has a positive effect on the anticorrosion coating.

Required capacity

When a person takes a shower, you will need about 20 liters of water. That is, multiply this indicator by the number of people living in the apartment, plus add about 12 liters to wash dishes. Rounding out these calculations, we get the required volume of the tank. Thus, the range of possible models when choosing which storage water heater is better is significantly reduced.

Kinds of heaters

There are two types:

• Tubular. Represented by a metal tube of any shape, inside which is a conductor, which has a high electrical resistance. After the tube is heated by a conductor, heat transfer of the liquid takes place. The insulation is presented in the form of dielectric sand, which fills the space between the tube and the conductor.

Important! Heat dissipation may decrease due to the appearance of scale. That is, if timely preventive maintenance work on the removal of scale, you may need more time declared by the manufacturer for heating the water.

• Dry. Such a heater can generally be called ceramic. On such a heater, no scaling is formed or at least many times less, so there is less heat loss. Its second advantage is the possibility of an independent replacement, if this part is out of order. But for the price of such water heaters are losing - they will cost, at least, 2 times more expensive.

Important! Relatively dry TEN have conflicting reviews on the forums. Some argue that there really is no scale, others - that it appears, so the quality of water should still be monitored. Most likely, it's the matter of which firm to purchase a storage water heater, because of the observance of the technology of production of equipment and the thoroughness of the selection of raw materials for the production of working units, much depends.

Power and length of the heating element

If one heater is installed in the storage heater, then 2 kW will be sufficient. Thanks to this, the water will quickly heat up, but you do not need to install a separate wiring.

Important! The larger the area of ​​the heating element, the greater the heat transfer coefficient and the smaller amount of scale will form on the square centimeter of the surface.

Protection and control systems

It is impossible to say unambiguously which storage water heater is better by this criterion. They can also differ by the following system device:

• Classic. In this case, the thermostat is used for switching on and off. And to check its operation, use an additional thermostat, which is connected to the control circuit.
• Microprocessor. All of the above is stored, only the electronic control board is added. The heating temperature is adjusted more smoothly, the temperature and the detected error codes are displayed on the screen. But at the same time, electronics is capable of failing for a huge number of reasons, respectively - an additional detail gives additional risks of earlier equipment failure.

Important! If there is often a temperature drop, the board may fail much faster than expected. Repair it at home is impossible, and in the service centers can not be found. In addition, such a failure is not guaranteed.

Enclosure

It is designed to protect all elements of the boiler. When buying it is worth paying attention to its thermal insulation.

Important! The most effective heat insulator today is polyurethane foam.

flow-type water heaters In such models, there is no storage tank for hot water. In addition, the heating elements in them are quite powerful - up to 30 kW.Advantage - in compactness, it is possible to install almost anywhere, where there is a cable with the appropriate section. But because of the power of this model will not withstand every wiring.

Recommendations

It is necessary to take into account the power, since it can vary in the range of 3-27 kW:

• For flow-through water heaters with a power of 3-8 kW, connection to conventional single-phase sockets is available.
• A more powerful model can be installed in an apartment equipped with an electric stove, where there is a three-phase voltage.

Installation methods

There are two options for installing such heaters:

• Pressure. It must be built into the riser pipe.
• Non-pressure. It is installed next to the water point.

Important! Proctors spend very much electrical energy, so they are often installed in cottages for temporary use.

Popular manufacturers

Now on the market, water heaters are presented in huge quantities. There are a number of manufacturers who have been leading for several years already. Consider a water heater cumulative which firm is better.

Electrolux

This manufacturer is distinguished by the goods with a decent quality and excellent price. The installation is quite simple. The surface in contact with water is coated with a special anti-corrosion coating. Due to this there is no oxidation, no harmful substances enter the device.

In all devices, the temperature mode is very smoothly controlled. This moment is very important for people who like to take a bath at a comfortable temperature. In the question of which water heater is better and cheaper, Electrolux certainly wins.

Ariston

Units of this popular brand are distinguished by stylish design, excellent additional functions and low price. In the event of an electrical breakdown, the protective shutdown mechanism that the tanks are equipped with will operate. In addition, the storage water heater of any model is equipped with a special safety valve that will save the unit under excessive pressure.

A nice bonus is the availability of the function of accelerated heating, thanks to which the water of the right temperature will not have to wait long.

Thermex

When reviewing which company to choose a water heater for electric storage, you can not miss the manufacturer of Thermex. Products of this company are characterized by low power, but they quickly heat up. This means that while energy is saved, the water is heated, and you do not need to wait.

The storage water heaters of this company are characterized by a convenient temperature setting, good power and long service life, which does not require repair or replacement of parts. Choosing BOSCH products when deciding which boiler is best, it is necessary to take into account that the price will be quite high. But this is a payment for fine quality.

AEG

Storage water heaters of this manufacturer differ in convenience and small size. Such boilers are suitable for small dwellings where space saving is required. Usually the buttons are carried to the front side, which is very convenient to use.
