Market Review

Within a billion dollars. Market overview of water heating systems from Litvinchuk Marketing

The market for water heating systems can be represented as a diagram. Boilers produce heat, pipes deliver it to the consumer - radiators. There are also pumps, gate valves, expansion tanks and other network equipment, but these three segments are fundamentally important in heating systems. If we measure these markets in money terms, then their volume in final retail prices is very similar. According to the results of 2015, each of the three segments of the heating market is within the limits of 1 billion dollars.

It makes little sense to heat the premises during the absence of the owners. But the most radical way - turning off the boiler - is not good: the heating will freeze. Therefore, in almost any system, frost protection is provided. If the temperature of the boiler water drops to a certain limit (usually up to 5 °C), the system switches to heating mode (water, but not rooms). Another protection measure that is more often needed in the summer is the periodic inclusion of circulation pumps so that their rotors do not “sour”. These security measures are usually, if they can be configured, only at the service level, access to which is either limited for the user (for example, you need to enter a password) or is not recommended.

Features of choice

How to choose the right Russian electric boiler, you will learn from the following points:

You should not make a purchase decision based only on the attractive appearance of the structure.There are much more important parameters that determine whether the room will be heated efficiently and quickly. Consult with electrical experts, ask about the specifics of the electrical network in the area. The start of the units can be single-phase or three-phase (220 V or 380 V respectively). If the boiler is up to 12 kW, then you can choose any connection option. If the power of the unit is greater, then only 380 V

Pay attention to the heating method. Domestic electric boilers can be heating elements and electrode

Each of them has its own advantages and disadvantages. For example, electrode boilers imply a method of water ionization and are listed as more modern, as opposed to boilers with a tubular electric heater. However, they have many restrictions on their use. Note that power adjustment can be smooth or stepped. See what's included. A Russian electric boiler with a complete set does not require the purchase of additional elements, so such an assembly will be the cheapest. If you decide to buy a unit with separate components, it will be more expensive (here it is worth considering the price of installation). Type of instalation. Russian electric boilers are most often purchased in a hinged version than a floor one. They save space and look more aesthetically pleasing.

Which company's electric heating boiler is better

1. Good inexpensive electric boiler RusNIT 209M

Rating: 9.9 out of 10.

Average price: 16279 rubles.

A compact, lightweight electric boiler of domestic production can be called the best among inexpensive ones.

From the reviews of the RusNIT 209M electric boiler:

“I have had an electric RusNIT in my dacha for 2 years now. Haven't let me down yet. The house is still warming up perfectly. It is good in it that when turned on, the system does not immediately load, it distributes the load evenly over each phase. And this means that, including other devices, you can not be afraid that they will burn out.

It is only important that the boiler is installed by specialists, and service maintenance must be carried out on time.”

When choosing heating equipment today it is easy to get confused, as there is a very wide selection of models on the market. There are both simple boilers for an apartment, and more sophisticated equipment designed for installation in a large country house or in the country. All of them are different in terms of power, additional features, connection technologies.

In order not to make a mistake with the choice, you need to pay attention to the rating, which clearly demonstrates which equipment is optimal in certain conditions.

To choose the right boiler, you need to pay attention to the rating, which demonstrates all the advantages or disadvantages of the equipment.The choice of a gas boiler will be much easier if you know exactly what functions are needed, what design power can satisfy all heating and hot water needs. The rating will help to understand all the intricacies of such installations.

When is an electric boiler the best solution?

Gas is not available to everyone: some settlements are located too far from the highway, and sometimes installing a gas boiler is not at all appropriate. For example, for a country house that is heated several times during the winter, it makes no sense to purchase an expensive set of gas equipment.

Solid fuel boilers also have a number of disadvantages: it is necessary to harvest and store fuel, and most solid fuel units cannot work for a long time, more than 4-5 hours, on one load of fuel. In addition, they are inertial and do not allow precise temperature control. In this case, the electric boiler is able to solve the heating problem quickly, reliably and at no extra cost.

Advantages of electric boilers for a private house:

• easy to install, connect and maintain;
• have a high level of automation;
• allow you to accurately set the desired temperature;
• work silently;
• no need to connect to a chimney;
• do not require a separate room, most household models are mounted on the wall with their own hands.

Flaws:

• require connection to the shield with a separate cable;
• boilers with a power of more than 9 kW are produced only for a three-phase voltage of 380 V;
• due to high electricity tariffs, heating costs several times more.

MAINTENANCE

In this case, it is necessary to tighten the screws for fastening the wire clamps suitable for the heating elements, the contacts of the electromagnetic starter, the ground and neutral terminals, and also to check the reliability of fastening the sector on the cover of the heat exchanger tank.

Possible malfunctions in the operation of the heater and their probable causes are listed in Table 4.

In order not to make a mistake with the choice of a suitable model, the best solution would be to seek advice from electricians.

Buyer Tips

When choosing an electric boiler for heating a private house, you should pay attention not only to reviews and electricity consumption, but also to other parameters. 1. Mounting method

In an apartment or in a private house of small size, it is optimal to install a wall-mounted boiler. They look aesthetically pleasing, neatly fit into the interior of the home, and at the same time are able to produce a significant temperature. As for the floor options, they can be attributed to industrial or semi-industrial models. These are units for large households with a power of 24 kW.

These are units for large households with a power of 24 kW.

2. How to connect to the mains. Economical electric boilers of low productivity are plugged into a regular 220 V outlet. But for units of medium or high power, it will be necessary to lay a three-phase 380 V network. A conventional 220 V network will not pull such a load.

3. Number of connections. Here is the standard classification: single-circuit and double-circuit models. The first ones are exclusively for heating, the second ones also heat water for plumbing.

4. And yet the main indicator is performance. It determines the consumption of electricity and the heating area. Standard minimum - 100 watts per square meter

Pay attention to this point: the worse the thermal insulation of your house, the more power the boiler will have to buy, and, accordingly, you will have to pay more for electricity later.

A few more guidelines. In terms of current strength, it should be limited to a maximum of 40 A. Electric boiler nozzles - 1 ½ ″ or more. Pressure - up to 3-6 atmospheres. Mandatory power adjustment function - at least 2-3 steps.

Be sure to take an interest in the quality indicators of the local power supply - if the voltage drops to 180 V in the evenings, the imported model will not even turn on.

Before buying an electric boiler for 10-15 kW and above, find out if the transformer from which the house is powered will pull. And then you will have to lay an additional line to your estate.

As for specific models, the most popular are imported, as they provide high performance with minimal power. Among the most bought, according to sellers, are:

• wall-mounted, single-circuit Tenko KEM, 3.0 kW / 220V, cost around $ 45-55;
• wall-mounted, single-circuit UNIMAX 4.5/220, cost $125-200;
• wall-mounted, single-circuit Ferroli LEB 12, 12 kW, price - $ 350-550;
• wall-mounted, single-circuit Protherm Skat 9K, 9 kW, cost $510-560.

A bit of history about Rusnit

In order to find out everything about electric boilers from this manufacturer, you should look at the time the company began its activities. It was founded in 1994 and is considered a subsidiary of the Krasnoye Znamya plant from Ryazan, which supplied devices for the Russian space industry.

But in the 1990s, he had to switch to the production of more mundane electric heaters. The first of them was designed at the plant, and only then the Rusnit company appeared, which included the production capacities of the enterprise and the intellectual potential of its engineering staff.

Shortly after the formation of the company, its first invention appeared - an electric device for heating water "Ranit". It was demonstrated in Brussels, at the exhibition of innovations and was awarded the Gold Medal. And although it had many innovative technical solutions, it did not enjoy success on the market, as it turned out to be very complex, and, therefore, not reliable enough for long-term operation.

All these shortcomings were taken into account in the following developments of the company and electric boilers of the Rusnit brand were born. They had a fairly simple design, reasonable price and were highly reliable.

The developers paid great attention to their safety and durability. Today, the company's products are in sufficient demand, they have international certificates of conformity and are constantly being improved.

RusNit K

Those who live outside the city or have a dacha are well aware of the state of the local power grids. Voltage drops often occur there, the poor quality of the lines themselves does not allow connecting powerful loads. For this, RusNit electric boilers were created, the technical characteristics of which are adapted to rural areas.

Devices can smoothly adjust the temperature heating of the liquid and stepwise adjustment using low voltage relays. Installation of RusNit K does not require different permissions.Plus, they are easy to repair. The power of heating devices starts from 5 kW.

In this class, the RusNit single-circuit electric boiler for 6 kW 206K is popular. It has a mechanical control, wall mounting. As with other devices, the manufacturer provides a two-year warranty. This electric boiler is adapted for operation and repair in rural areas. Switching of tubular electric heaters is carried out by low-voltage relays.

Device features

The RusNIT company was previously part of the Krasny Luch military space enterprise. The company itself was founded in 1994 and initially produced quite sophisticated equipment.

Since this did not bring any profit, the management decided to produce simple heating equipment.

This is a great option in cases where it is not possible to connect to the main gas pipeline.

The main features of these boilers include:

• the ability to set the required power;
• maintaining an accurate temperature in the room;
• the presence of external indicators that allow you to monitor the operation of the device;
• equipped with a circulation pump, which increases efficiency.

What gives an electrode boiler

The very idea of ​​​​the electrode boiler is that. to refuse the use of TEN. If you now look at the diagram of the electrode boiler, you will see that the electric current passes through the coolant from the electrode, which is energized to the boiler body, which is also a conductor.

Of course, any competent electrician will say that there is no movement in reality.

But it doesn't matter to us right now.

What is important is that the losses in this case are minimized.And thanks to this, the electrode boiler has an efficiency of up to 97 percent. Where do these same 3 percent of 100 go, I wrote to you a little higher

Where do these same 3 percent of 100 go, I wrote to you a little higher.

It is important for us that, other things being equal, the electrode boiler will have slightly less electricity consumption than a classic boiler with heating elements. This time. Secondly, the process of heating the coolant itself is faster, because during the operation of the electrode boiler, the entire volume of water is heated at once, and not just the layer next to the surface of the heating element.

But in such a scheme there are not only pluses, but also minuses. You can read about them below, in the "Reviews" section.

Number of circuits

The device of a double-circuit boiler.

When installing a heating boiler, you can provide the house with an uninterrupted supply of hot water, but the equipment for this must be chosen especially carefully. In this case, it is necessary to make a choice between devices with one or two circuits. Single-circuit devices allow you to organize only a heating system, since they are not designed to heat water that is supplied to the user in the taps in the kitchen or in the bathroom. If there is a need for this, it is necessary to choose double-circuit gas boilers. There is a separate classification here: wall-mounted, floor-mounted, flow-through gas boilers and with large storage tanks are produced.

Which boiler should you choose? You must first determine what functions are required from the equipment. For example, single-circuit devices are able to supply coolant for underfloor heating.

Flow type equipment is used when almost instantaneous heating of water is required, while they pump 10-15 liters through themselves in a minute, heating this volume to the set temperature.

Heating double-circuit boilers have additional tanks with a certain capacity. They have a volume of already hot water, but when it is supplied, it may not always be hot right away, and this leads to fluid consumption. Therefore, the choice must be made based on how economical and effective the equipment is, whether it fully meets all the requirements of operation.
