How many boilers were received by the Armed Forces of Ukraine in Donbass, how many equipment was given to the militia

Types of heating boilers

If you are faced with the choice of which heating boiler is best to buy in Ukraine, then first of all you will think about the types of fuel for this boiler and the cost of its operation. There are three types of fuel that home heating systems operate on, and boilers, respectively, can be:

• Electric ones are the most environmentally friendly, easy to operate and almost silent. However, the operating cost of such a device is very high. Also, the operation of the unit is negatively affected by power outages and voltage instability. Such heating boilers require separate wiring for the house, which must be designed, preferably at the construction stage or during a major overhaul.
• Solid fuel - operate on all possible types of solid fuel: wood, coal, peat briquettes. These are the most popular boilers for heating private houses. They are unpretentious, easy to use, relatively inexpensive. Solid fuel boilers are completely autonomous. They do not require complex connection to the gas pipeline or to the power supply. In addition, there are universal heating boilers - these are double-circuit devices that run on solid fuels, which can also be converted to gas.
• Gas - modern self-contained long-burning installations that do not require complex maintenance and constant attention. The most popular, because today gas is the cheapest fuel. Among the options to choose from are gas boilers with natural or forced circulation, the difference lies in the configuration of the system with a pump, which can be either part of the system or a structural element of the boiler itself. It is worth noting that almost all gas wall-mounted boilers are equipped with such pumps.

Boiler installation methods

There are only two options here - wall and floor. Wall models have appeared relatively recently, but the reviews of the owners of such models speak of their effectiveness. They are optimal in terms of economical use of space and serve as a boiler for hot water heating and for providing hot water. Due to their small dimensions, they can be installed in the kitchen, in the attic or in the living room. Floor models are optimal in large areas. These are quite large devices and they have a wide range of capacities, and some models can be used as industrial units.

Common models

The Aton gas double-circuit parapet boiler is quite well known among residents of apartment buildings. It belongs to Russian-made goods, therefore it perfectly fits the connection standards and does not cause problems. Despite the domestic assembly, the quality of this equipment is high due to German and Italian components.

The parapet gas boiler Ariston is also popular. This well-known Italian company produces devices with an automatic control system. Boilers are characterized by low noise level, compactness and economical fuel consumption.

Three firms stand out among Ukrainian manufacturers: Danko, Vulkan and Ross

Among them, it is important to be able to choose the right model. So, the selection of a parapet heating gas boiler Danko according to the parameters is quite simple: it is important to rely on the required amount of heat based on the quadrature of the house

They are economical and have a low cost.

In contrast, Ross parapet gas boilers have mixed reviews. First of all, this is due to the fact that not all models meet the requirements of Gorgaz, so you should be careful when choosing.

The Vulkan model has its own characteristics.So, the first series of release did not have a thermocouple, so it is better not to buy such ancient devices. The best option is the latest releases, where a thermocouple for the gas boiler Volcano is provided. It is necessary for an emergency stop of work, so that in the event of a breakdown or attenuation, the gas does not enter inside.

Recently, the boiler broke down completely, the repairmen said that it was outdated and still needed to be replaced. This model is not repairable, there are some irreparable damage. In any case, I want to choose the appropriate option, but I do not know which company is better. I don’t understand what Dani’s parapet gas boiler is. I heard about Ariston and other companies, but I don’t know the quality of this equipment. However, I don’t want to spend a lot of money, only for imported goods, it’s better to have something more affordable, but also of high quality.

Anna, Dani - excellent chimney models with an open combustion chamber. They are quite practical and simple. My friend has had such a boiler for 10 years without a single failure or breakdown! I then installed the Ukrainian Volcano for myself, so during this time I had to change spare parts for it a couple of times.

And I installed Ariston for myself and have no regrets. Firstly, it is quite powerful and economical, secondly, it has a cool design, and thirdly, I have not heard that they break or do not fit the requirements of the installation. I recommend to everyone! Although its cost is slightly higher than domestic models, we are pleased with the result.

The lineup

Today, parapet models of boilers are presented on the market with a wide variety of models from various manufacturers.

In the product line you can find boilers with various capacities, which are designed for heating houses and apartments.

Boilers are also classified according to the type of installation, the number of circuits and performance characteristics. These parameters determine how much a gas boiler costs and how it will prove itself in the heating system. Discerning buyers who want to find the best heater option before choosing a particular model should study products from the main manufacturers operating in the home heating market.

Boilers from the Luch brand - functionality and reliability

The parapet gas boiler Luch is produced in Taganrog. This boiler differs from analogues in a compact body, a simple installation procedure and an inexpensive price. Various models of boilers can be used to heat houses ranging from 80 to 180 square meters. When choosing the power of the boiler, it should be borne in mind that the device should not work for wear. Experts recommend selecting the power of the device in accordance with the requirements of the heating scheme developed by competent heat engineers.

The specifics of the work of parapet models from the Luch brand is represented by the following list:

• rational gas consumption;
• complete combustion of the energy carrier in a sealed chamber;
• convenient location of pipes for connecting the gas supply line;
• low heat loss;
• the presence of a tubular heat exchanger that provides maximum boiler performance.

The device of a parapet gas heating boiler

The internal structure of the parapet gas equipment was designed in such a way as to prevent the combustion of oxygen from the room in which the boiler is installed. For this purpose, several design changes were introduced. As a result of modifications, a gas-fired boiler was obtained, characterized by the following characteristics:

• Energy independence - the boiler in the basic modification is able to work without electricity.
• Sealed combustion chamber - primary and main gas burner, mounted in a closed combustion chamber. When burning, air is taken directly from the street.
• Vertical heat exchanger - built into the top of the furnace. Vertical hollow plates, made of heat-resistant steel. The coolant circulates inside. Hot water supply is provided by a built-in copper coil.

The principle of operation depending on the time of year. The parapet double-circuit gas boiler has two operating modes, depending on the season. In the winter season, heating of the heat carrier and hot water is carried out. Heating occurs alternately. If the boiler starts to heat water for domestic hot water, the heat supply is turned off and vice versa. The principle of operation in the summer eliminates the use of a heating heat exchanger. Hot water is heated exclusively by means of a copper coil. Gas consumption in different modes is different. When heating hot water in summer, the costs are only 30% of the total energy consumption during the heating season.

Automation - conventional boilers, equipped with a mechanical thermostat for gas supply. Adjustment is carried out by means of a rotary mechanism connected to various sensors. Some modern models are equipped with a microprocessor controller that regulates the operation of the boiler in automatic mode.

The internal structure and operation of the parapet boiler is in many ways reminiscent of what is used in units of a classical design. But, there are differences that make it possible to widely use the equipment.

What is the difference between a parapet boiler and a chimney boiler

The non-volatile parapet gas boiler is a closed-type unit. Gas combustion and all other processes take place in a completely sealed closed combustion chamber. The main difference from the classic units are several characteristics:

• The absence of a classic chimney. In classic boilers, air is taken directly from the room. After burning the gas, the combustion products go into the vertical chimney under the action of natural draft. In parapet equipment, air is taken in and combustion products are removed using a coaxial chimney.
• The special design of the combustion chamber - a steel heat exchanger, two burners, a DHW coil, are enclosed in a sealed chamber connected to a coaxial chimney. Air intake is carried out along the outer contour of the chimney, after which it enters the burner from below. The heated air passes through the vertical heat exchanger and is discharged from the boiler body through the core of the coaxial pipe.

The normal volume of gas consumption for a parapet boiler, per 10 kW, will be about 1 m³ / hour. A double-circuit unit will consume approximately 15-20% more fuel needed to heat hot water.

Advantages of double-circuit parapet boilers

Advantages of double-circuit parapet boilers

• small size and overall compactness of the equipment;
• the possibility of location in any room, even in the kitchen;
• ease of installation: under the windowsill or above the table;
• the presence of coaxial pipes for easy smoke removal.

Wall parapet models

Parapet gas heating boilers are easy to install, especially if it is a wall-mounted model. Unlike floor models, they do not need a specially equipped room according to the requirements of gas workers. Moreover, their installation does not require a chimney outlet, an ordinary window and a ventilation hole are sufficient. There is no need to comply with strict requirements, to build a complex chimney system and find enough space for the boiler.

Another advantage of wall-mounted models is the ability to connect anywhere in the system. A beautiful appearance will only add coziness to the kitchen or bathroom, which will not cross out the overall design of the room.

Wall-mounted boilers have an automatic control system. They have a piezoelectric ignition system, moreover, in the place where they are installed, radiators are not needed.

What are solid fuel boilers?

Solid fuel boilers are an indispensable unit for increasing the level of heat in buildings that are not connected to a gas main. They will also become an excellent device for heating houses with weakened electrical wiring. A solid fuel boiler is able to maintain a normal temperature for three days. The owner of such a device does not need to constantly throw firewood. Thus, even far from civilization, the house can be heated in accordance with all standards.

Modern manufacturers produce a wide range of equipment of this type. New models are constantly being developed. Solid fuel boilers began to gain popularity as the main source of heating. This is due to the high cost of connecting the building to the gas pipeline.

Increased utility rates are also taken into account. Therefore, manufacturers set as their goal to provide potential buyers with good conditions for savings.

It is conditionally possible to define several types of solid fuel boilers:

• Long burning. The most popular boiler, which is characterized by increased practicality and ease of use. In the manufacture of this design, emphasis was placed on the possibility of the longest possible burning. If you fill this device with a prescribed amount of fuel, it will be able to maintain the desired temperature in the house up to several days. At the same time, it does not need constant supervision and fuel supply.
• Pyrolysis (gas generator). This type of solid fuel boilers separately burns the fuel placed in it and the volatile substances coming out of it. Such boilers are characterized by increased maintenance of a given level of heat. They are able to set the desired air temperature for about 12 hours from one fuel tab. The fuel burns completely, thereby guaranteeing full efficiency. In addition, such boilers practically do not emit harmful substances into the atmosphere, being relatively environmentally friendly.
• With automatic fuel supply (pellet). They are considered the most convenient boilers. They work on the basis of pellets - these are wood pellets that are used as fuel. This technique is characterized by an increased service life. It is guaranteed to be able to serve its owner for about 25 years. The device is highly economical. Its efficiency is 95%.

How to choose a good solid fuel boiler

Equipment of this type is purchased with the expectation of many years of use. That is why the issue of her choice must be approached with the utmost responsibility. First of all, you need to decide on the most rational type of device data. To do this, it is worthwhile to study the individual characteristics of the three types of solid fuel boilers, to find out the details of their functioning. After that, you can decide on the most rational option.

The material from which such equipment is made deserves no less attention. One of the most common types is considered a steel boiler. It is characterized by sufficiently high strength and stability. A more durable option is considered cast iron. It copes much better with mechanical stress. In addition, it is able to withstand long operating periods.

It is also worth paying attention to the manufacturer of equipment of this type. Among all manufacturers, Cordy won the most popularity.

It produces quality boilers that perform well during use. The products of this manufacturer economically consume fuel. They are implemented according to a rational pricing policy.

Installation of a floor and parapet boiler

Ease of installation and delivery is ensured by the presence of special legs or transport wheels. Thus, they do not cause difficulties. Moreover, such models are sold assembled, which makes the task easier for specialists. The parapet unit is the best alternative to floor and wall models. It has a non-volatile heat generator, which makes it possible to provide autonomous heating for two-room apartments.

It should be remembered that among the various boilers there are exceptions: models that do not always fit the parameters. Also, the requirements and specifications do not always provide for the possibility of heating a wooden room.

The cost of installing boilers cannot be called cheap. First of all, this is due to the complexity of the mechanism, the responsibility of employees and the need to call only licensed specialists to connect. It is forbidden to do the installation on your own, so you will not be able to save money. Depending on the difficulties of connecting and the type of boiler, the price for such a pleasure will be about 300-650 dollars.

This cost includes installation, delivery, purchase of parts, filling the system with water, checking all parameters and safety precautions and start-up.

Which parapet boiler is better to choose

When choosing any model of a heating boiler, they are guided by its thermal characteristics and additional functions. The performance of the unit, the possibility of heating water for domestic needs, as well as the plant that manufactures heating equipment are taken into account:

• Productivity - average power indicators, calculated by the formula 1 kW = 10 m². This formula is suitable for well-insulated buildings in the middle regions of the Russian Federation with a ceiling height of no more than 2.7 m.
• Functionality - a parapet single-circuit gas boiler, works only for heating. To connect hot water, you will need to install an indirect heating boiler, which will require additional financial costs. Double-circuit parapet gas boilers are convenient in this regard, as they have a built-in water heating function and a switch that allows you to switch the unit to summer or winter operation.
• Manufacturer - the rating of the most reliable boilers, headed by German manufacturers, Austrian and Czech models follow right behind them. Domestic parapet gas boilers, with a closed combustion chamber, have an attractive cost and good thermal performance.

Judging by the reviews, the best manufacturers of gas parapet heating boilers are European and Russian companies. Although the products of the latter are somewhat inferior to European counterparts in terms of efficiency and degree of automation, they are fully adapted to domestic operating conditions and are sold at an affordable price.
Models manufactured by factories located in neighboring countries are popular:

• Domestic gas parapet boilers of Russian production - Lemax, Hephaestus, Barsky Machine Plant, Helios, Danko, Conord, HeatLine, Taganrog Gas Apparatus,
• Ukrainian parapet-type gas heating boilers for apartments and private houses - Termomax, ATON, Atem, Mimax, Termotechnik, Mayak, Dani, Proskurov, ROSS, Ochag.

The cost of parapet boilers, Ukrainian and Russian manufacturers, is 2-3 times cheaper than European analogues.

Classification of gas boilers

According to the method of installing the system, boilers are of two types - floor and wall. For an apartment building, it is better to choose wall-mounted options, since a separate room is not required, and they fit any interior.

According to the purpose of the device, they are single- and double-circuit. The first type is adapted only for space heating. But the second type is suitable for both heating and water heating. This is a great option, both for a private house and for apartment buildings, but if the system breaks down, you can be left without heat or hot water. In such cases, it is advised to install single-circuit boilers with an expansion tank for heating water. So you can avoid unforeseen situations and save hot water in the house.

According to the ignition method, devices with piezo ignition are distinguished, which are turned on manually by pressing a button. Also with electronic ignition, that is, automatic.

Another classification divides the device according to the completeness of the fuel energy used:

Convection (heating). Uses low calorific value

In an installation of this design, it is important to prevent the condensation of water vapor with dissolved acids on the walls of the heat exchanger, furnace and chimney.

Condensing. The highest calorific value is used due to the condensation of products burning on the walls of the economizer.

Parapet

It has a small size, so it is great for both a private house and an apartment. Smoke extraction uses coaxial pipes, which reduces the chances of carbon monoxide spreading throughout the room.

When choosing, it is also worth considering the power indicators. Double-circuit wall or floor have only general characteristics that will not tell you which option is better to choose. You need to rely on power when the volume of the house and heat loss are calculated. To determine this indicator, you need to find out the heated area, the number and condition of windows and doors, the thickness of walls, roofs, floors, ceiling height, type of glazing, and the presence of a basement.

Advantages and disadvantages

Reviews about gas boilers can be very different, but for an objective assessment of the operation of this system, you need to consider all the pros and cons of the device. Compared to a number of other devices for space heating, this device is light and easy to install and operate. For installation, standard fasteners and pipes are used. Quite often, the manufacturer Ariston (ariston), FERROLI, BOSCH and other companies provide all the components for installation or describe in the instructions which devices will be needed. This simplicity minimizes any complexity in installation. You can install a gas heating system on your own.But when carrying out commissioning and launching actions, you need to invite a specialist.

At home, such equipment from the manufacturer Aton (aton) is the most useful. If you install a pump for forced circulation of water to the structure, then it is possible to heat the most distant and largest rooms in a short time. If all safety rules are followed correctly, the gas system will provide a minimum percentage of ignition.

Special sensors are also installed in the system that regulate the fuel supply, the presence of a flame, and the temperature regime. Safety also lies in the low percentage of emissions of harmful substances from gas combustion. They are also quite compact and can fit into any interior.

However, behind all the positive characteristics, there are also significant disadvantages. The manufacturer Vaillant (vailant), Aton, Ariston (ariston), FERROLI, BOSCH and other well-known companies have some shortcomings in the system. During the gasification of the premises, you need to be prepared for the fact that special gas services will require a project for carrying out the device, you need to coordinate all work with them and sign acts. Many experts argue that gas boilers are relevant only in very large rooms, more than 100 square meters.
