Service life of gas boilers. Service life of gas boilers

Each person chooses the best for himself. In the concept of "best" each of the buyers puts his own meaning. Reliability? Security? Price? Appearance? All this can be correlated with gas boilers. What are the best gas heating boilers? It all depends on what features you prioritize.

Many gas boilers have an automation system, pumps that run on electricity. Such boilers cannot function without a constant supply of electricity. If there are power outages, such devices will not work.

It is necessary to consider: what type of boilers is suitable for floor or wall housing. If a high power boiler is required, then it is best to choose a floor type of equipment. The disadvantage of such a unit is that it is necessary to allocate a separate room for it. For regular kitchen fit more compact version- wall-mounted boiler.

It is worth considering such a characteristic of boilers as the type of combustion chamber. Equipment with an open chamber burns the air in the room. Such boilers require an equipped chimney and a constant flow of air from the outside. It should also be noted that their body overheats, so a boiler with an open combustion chamber should not be installed next to counters, wooden furniture and curtains. Boilers with a closed chamber have a coaxial pipe in their structure, which absorbs air from the street and brings it back. Such a boiler is an economical option, since in coaxial pipe there is a uniform mixing of gas and air, so the boiler body with a closed combustion chamber does not overheat.

The modern market is to choose gas heating boilers to your taste, and which one is better for the buyer to decide. The choice of equipment depends on the needs that are most important to the consumer.

Service life of a wall-mounted gas boiler

The life of a wall-mounted gas boiler is several times less than that of a floor-standing one. What caused such a significant difference? Direct dependence on the material from which the boiler heat exchanger is made: in all mounted boilers, the heat exchangers are copper, and in the floor boilers they are made of steel or cast iron. Copper gives the boiler relative lightness, but copper equipment is fragile and quickly becomes unusable. For such a heat exchanger, a high purification of the coolant is required. If it is not cleaned, copper will oxidize. At proper care copper heat exchanger will last 5-10 years. The service life also depends on the manufacturer. Mounted boilers have less power than floor standing ones, so often when used they have to work at full power, this reduces the life of the equipment.

Service life of floor boiler

Floor boilers have a much longer service life than mounted boilers. This fact is also determined by the material of the heat exchanger. A heat exchanger made of steel or cast iron, with proper operation and installation, will last up to 20 years. Floor boilers are much more powerful than mounted boilers, so they are rarely turned on at full power. If you periodically carry out deep cleaning of the coolant, then the gas boiler will serve for more than a dozen years.

Each manufacturer declares its warranty periods for the operation of gas boilers, which are based on their specifications Oh. Tip: for greater reliability, you must purchase gas equipment only trusted brands, for example, as well as trust their installation of boilers to professionals.

The cost of gas boilers

The cost of gas boilers domestic use fluctuates over a fairly wide range. Gas equipment, comparing the indicators for the quality of work, safety, service life, ease of use, economy, you can create a conditional classification of price categories.

The price of gas heating boilers can be classified into 3 groups:

1. High-quality and expensive gas boilers of German brands.
2. The average price of a gas boiler with good quality equipment from Italian companies Ariston, Baxy, Beretta, Ferroli, Baxy, Fondital; Czech companies: Mora, Viadrus, Dakon; Korean firms: Olympia and Kiturami; Spanish firms: Roca; Japanese company: Rinnai.
3. Cheap gas boilers of domestic companies: Zhukovsky Machine-Building Plant, Lemax, Rostovgaz oapparat, AGRORESURS.

Overview of gas boilers

"Prometheus" is a well-known domestic brand of energy-independent floor-standing boilers with a steel heat exchanger. Prometheus models are used to heat rooms with a large area of ​​​​up to 750 square meters. meters. The efficiency is 92%. Microtorch burner with automatic ignition, plate heat exchanger made of steel ensures efficient and safe operation of the heating system. This company produces not only high-quality models that can successfully heat areas from the size of one apartment to large buildings of various functions, but also affordable. Gas boiler "Prometheus" - the best combination of quality and price.

Neva gas boilers are a St. Petersburg brand of Gazapparat OJSC, which specializes in the production of gas boilers and water heaters. The company carefully checks and tests all equipment for performance, electrical safety and tightness. The range of gas boilers is represented by 3 classes suitable for any wallet: “economy class” (Neva brand), “comfort class” and “premium class” (Neva Lux brand ). Since 2005, the company has been assembling wall-mounted gas boilers from ready-made purchased European kits. Since 2007, she has been manufacturing Neva Lux equipment, which has parts manufactured by the company itself. All boilers are made in modern design, the consumer can purchase equipment at an affordable cost.

The Korean company Daesung is a leading manufacturer of heating boilers. The company's boilers are economical, of excellent quality and safe in operation. The first heat exchanger is made of copper, therefore it has a high efficiency and, accordingly, long term operation. The second heat exchanger is made of steel plates, so there will always be hot water in any quantity and instantly. The boiler is usually used to supply hot water.

Mimax LLC is a domestic company, the main direction of which is the manufacture of automatic gas equipment. Mimax gas heating boilers have a 3 mm thick steel heat exchanger, thanks to which they have excellent heat dissipation. When assembling the equipment, heat-resistant materials are used to significantly reduce the temperature outer case up to 40 -50 °C. The efficiency of the company's boilers is 87%. The service life of heating equipment is more than 15 years. The Mimax company has developed a series of universal boilers that operate on both gas and solid fuels. Wood, coal, peat are used as fuel. The average time of transition from one fuel to another does not exceed 1 hour.

Gastroy LLC is engaged in the production of gas boilers of the Ochag trademark, which successfully sells 40 types of heating boilers. Among them are gas boilers for heating the hearth, designed to provide heat to small rooms with an area of ​​​​about 1000 m². All Ochag devices are easy to use, have an excellent level of quality combined with reasonable prices.

Protherm's Medved gas boiler has a heat exchanger constructed from several links. This design allows the combustion of fuel to give off heat to the heating water as much as possible. Advantages of heating equipment of the Bear series: compact dimensions boiler, easy installation, simple control, efficiency is 92%, maximum heat transfer with minimum losses, regulation in two steps.

Decent models are presented on both the domestic and European markets for heating equipment, from which you can choose a boiler that suits you in terms of functionality and price.

Heating for houses and apartments is inevitably associated with material costs. Consumers know that the price range for gas boilers, installation and service assistance is quite high. For this reason, many seek to make minimum expenses for the purchase, installation and operation of boiler plants.
But not very expensive gas heating boilers can be unreliable and lead to serious problems during the operational period, and, consequently, additional costs. In the worst case, inexpensive boiler installations can lead to the fact that the home will always be warm. That is, when choosing economical gas heating boilers, the principles of reasonableness should be used.

The most economical are Navien gas boilers, which have an efficiency close to 100%. The efficiency of an economical gas boiler, which has a premium class, has a maximum value of 94-96 percent.
The efficiency of a middle class gas heating boiler is much lower and is approximately 70 - 90 percent. As for the cost, the premium and middle class have a difference of almost half. For this reason, savings is a very tempting factor. But experts are not recommended to purchase very cheap Russian gas boilers. The whole problem is that in a few seasons the difference in cost will be neutralized. And in the next few decades, owners will have to overpay significant amounts for the operation and maintenance of a gas installation.
Fuel types: which one to choose
A kilowatt of thermal energy will cost depending on which type of fuel is chosen. It is a well-known fact that natural gas is the cheapest type of fuel. If your household has gas, then the question of choosing an economical boiler for space heating should not arise before you. If you do not yet have gas, but in the near future it will be supplied, then it is worth buying a double-circuit gas boiler. The systems can operate on diesel fuel as well as on natural gas. And during the transition from one fuel to another, it will be possible to avoid additional costs. Heating boilers gas Lemax require only a change of burner, and the installation itself will operate on gas.

Economical gas heating boilers have one very important criterion - service life. Economical gas boilers continue to live for about half a century, while middle-class equipment will last about 10-15 years. But has importance not only the service life itself, but also how long it can run smoothly. However, it is directly related to timing. general operation. If you thoughtlessly save money and buy a low-quality Mimax gas boiler, then in a few years you may encounter an unpleasant need to repair or replace equipment in the midst of the heating season.
Boilers that run on gas can have two types of burners: atmospheric and inflatable. In an atmospheric burner, the process of formation of gas-air mixtures is carried out naturally. And in a pressurized or fan burner, gas is first pre-mixed with air, and then this mixture enters the combustion chamber. Economical Korean gas boilers have two forced-air burners. More than complete combustion natural gas, which makes it possible to achieve the highest possible efficiency. This means that operating costs will be reduced by 25-30 percent.

If your house does not have an area of ​​​​350 square meters, then you can safely refuse to install an expensive chimney. After all, the cost of buying a gas boiler Ross and its installation can be about 100 thousand rubles. It is also not necessary to allocate a separate room for the boiler room in order to reduce the useful area of ​​\u200b\u200bthe house. It is worth buying chimney-free economical gas boilers. They will help you save on installation, maintenance of the chimney, which will also not take up much space in the house.

Automatic control boiler

Economical gas boilers must be equipped with automatic control systems. Modern systems are very easy to use, they are reliable, they provide comfortable control of the temperature in the house, which, if properly configured, can save about 10-20 percent of fuel. That is, by reducing operating costs, the installation of a control system on a gas boiler will be paid off in the first year and in the future it will help save your money.

Unfortunately, among consumers who install for the first time autonomous systems heating, trying to save on maintenance. Indeed, if you abandon it, you can save 10-15 thousand rubles a year. But even after one season has passed, the focus of the burner may shift, soot may appear, deviations in the operation of the automation and the pump from the passport mode may appear. The error of work, at first glance, is not great. But it leads to an unjustified risk, a decrease in efficiency, and in connection with this, the cost of operating a gas boiler also increases. It is worth saying that it is still worth saving when purchasing a gas boiler, but this must be done competently and carefully so that you do not have to regret it later.

Before you install the boiler, you should carefully approach the question of where it can be installed. It can be mounted on residential floors in separate rooms and on ground floor, outbuilding or basement. The area for installation of the boiler must be at least fifteen square meters, and the ceiling must have a height of at least 2.5 meters. Must be installed fire door with the third type. The walls must have a fire resistance of at least 0.75 hours and, in accordance with the design features, zero limits for determining open flames. In the room where the installation of a gas boiler is planned, a sewer pipe is laid, with a diameter of 5 centimeters or more. If the room is located on the ground floor or lower, then it is necessary to make a separate exit to the street.

wall-mounted boiler

Due to its small size, the place for installing a gas boiler can be determined quite easily. Installation of a wall-mounted boiler can be done directly in the kitchen or in any other room. Wall-mounted boilers do not require free space and can be installed at the cost of wall mounts above other types of equipment or furniture that is located on the floor.

Installation of a gas floor boiler takes place in the following way: a place is selected for installing a gas boiler, the outlet of pipes for chimneys is prepared to the outside, mounted heating equipment, connects to the water supply, to the electrical network, gas network, chimney pipe. The place where the boiler will stand must be flat and made of non-combustible material. All filters that are included in the kit, as well as pipes that must be installed in the process of connecting to the city gas service. When connected, a ball valve is installed, thermal shut-off gas valve, gas meter and an indicator of gas content in the room.

If you want to do the installation of the heating system yourself, then the installation of a gas boiler must be taken very carefully. Since, if even minor errors are made during installation, the consequences can be very serious, and you will have to spend a lot of money to eliminate them. Therefore, during installation it is better not to rush. All the main tasks should be carried out gradually in compliance with all stages. If we talk about what time the installation will have, then experts recommend installing the boiler in the summer.

If your choice would be stopped on the boiler floor type, then you should immediately think about where it will be located. After that, you need to bring gas pipes and install the chimney. In order to comply with safety standards, the boiler must be installed on special stands. To do this, you need to prepare wooden formwork with a tedious area, pour a mold a few centimeters high cement mortar. The boiler can be installed on the podium after curing.

It is worth remembering that the chimney pipes must be carefully insulated. This is required so that the combustion products do not cool down in the chimney before they go outside. If carbon monoxide cools down in the pipe, it will lose its volatile properties and instead of the street, it will return back to the boiler, and from the boiler to the room.

Installation of a wall-mounted boiler

If you want to install gas wall boilers, then you need to purchase high-quality and reliable fasteners that can withstand the weight of the boiler. The place should also be chosen in advance, preferably closer to the bathroom or kitchen. After that, you need to carefully measure where the fasteners will be mounted. After this, the mounts are put on the mounts, proceed to the next installation step - run water and gas pipes. Don't forget to take care of quality chimney pipes.
During the installation of the boiler, you should definitely pay attention to the little things and details, as this is directly dependent on the efficiency and serviceability of the boiler installations. During installation, all nodes that are responsible for the security of the system must be connected, not only inside, but also outside. The main safety system includes protection against overheating, gas leakage, lack of smoke removal, as well as loss of electrical supply.

Powered by gas fuel, available to customers in a wide range. Modern models have many differences from each other both in design and in functional content. The introduction of new technological solutions, as well as the use of materials with improved performance indicators, makes it possible to regularly improve the level of technical characteristics of such units. This is confirmed by gas industrial boilers of domestic production. Russian enterprises produce high-quality equipment in this segment, focusing not only on the experience of foreign colleagues, but also on their own developments. It is worth noting the economic attractiveness of mass production This is facilitated by two factors. First, the payback of products that are not cheap. Secondly, the demand for high-quality and efficient units.

Russian production of industrial boilers

Characteristics such as reliability, safety and functionality are usually applied to imported products. This is especially true for high-tech equipment. However, examples of modern domestic enterprises show that our manufacturers can also offer a product of no less quality. Conveyors and machine-building machines manufacture parts and components according to European standards, and technologists improve approaches to assembly processes. It is also worth noting that the production of industrial gas boilers in Russia, as a rule, is complemented by design services. This means that already at the assembly stage, the customer can count on the complete compliance of the equipment with the requirements and characteristics of a particular boiler house. This is especially important when considering the capacities with which industrial and commercial units operate.

The device of the units

Most industrial models are designed for heating industrial buildings, workrooms and workshops. The design of boilers is also subject to these tasks. Its main element is the core burners. As a rule, a group of parallel rods is used, each of which has holes for the removal of the air-fuel mixture. In the process of mixing with air, a flame is formed, which evenly distributes heat over the entire area. Also, the device of an industrial gas boiler may include a water-tube heat exchanger, which is heated as a result of combustion of the gas mixture.

There are also more complex units that are equipped with flare gas burner elements. The peculiarity of such models is that all basic design together with the fan is installed on the front side of the case. In the boiler itself there is a nozzle, which, in fact, acts as a source of flame and heat propagation. On the market, industrial gas boilers with flare burners are available in two-pass or three-pass versions. The most powerful of them are capable of heating water up to 115 ºС, as well as producing high-temperature steam. At this point, it is worthwhile to take a closer look at the two main varieties of such equipment - steam and water-heating models.

Steam models

This category of boilers is designed to generate steam. Most enterprises using technological process steam, high pressure is required. Therefore, the performance of such equipment is made up of temperature and pressure indicators. For the most part, gas-fired industrial steam boilers are units that, through fire-tube structures, generate steam with a capacity of at least 0.25 t / h. Depending on the requirements of the enterprise, you can choose models with more power. As a rule, the maximum reaches 55 t/h. Pressure indicators, in turn, can be up to 30 bar, and temperature conditions - up to 300 ºС. Modern models are distinguished by the ability to work on various types liquid and gaseous fuel. When choosing, it will not be superfluous to take into account the additional provision of equipment in the form of deaeration devices, dispensers and bubblers.

Hot water models

Models with hot water supply are different symmetrical arrangement heating surfaces, but, as in the case of steam units, they operate on the principle of one- or multi-pass through the combustion product. At the same time, it is worth noting the versatility and versatility that industrial gas boilers are endowed with. The photo below, in particular, illustrates a hot water model that can work not only on gas source fuel, but also diesel.

When choosing such boilers, it is important to pay attention to the material of manufacture. In many respects, the reliability of the equipment, its safety and, as a result, the price depend on it. In some cases, such characteristics of work come first hot water devices, as the pressure level (the maximum is approximately 16 bar) and the heat output, which varies on average from 0.7 to 35 MW.

Assortment on the market

At the moment, however most of models available on the market refers to foreign brands. These are, for example, units from the German manufacturer Bosch, which supplies models with the ability to work both on gas and on liquid forms fuel. Also noteworthy are the Babcock Wanson models with maximum power up to 1757 kW. For large enterprises, it is worth noting the products of the Belgian company Prestige. It releases installations from several differing in high reliability and a working resource.

In turn, Russian-made gas industrial boilers are available in the lines of Turbopar, Gorgaz and Aguna companies. The factories of these enterprises are engaged in mass production, including units of increased power up to 3.6 MW. The models differ in having automatic systems, a variety of designs and the ability to adapt specifically to the requirements of the installation site.

Maintenance nuances

The long-term use of boiler equipment depends not only on the working resource provided by the manufacturer. To a large extent, it is determined by maintenance - its quality and frequency. Maintenance measures include maintaining the chimney in optimal condition and carrying out regular inspections of all flue systems. No less important is the cleaning of industrial gas boilers, for which the burner is located on the door. In this state, it can open to the left and right to allow cleaning. This operation should be carried out regularly, but taking into account the intensity of operation of the equipment.

Operational period

Subject to the manufacturer's recommendations, gas equipment can serve an average of 15 to 20 years. Again, the working life depends on many factors, including the materials used and the conscientiousness of the maintenance. In this regard, the service life of industrial gas boilers until the first cleaning is also important. Usually this period is 3000 hours. The need for a major overhaul is difficult to overestimate, but it should be carried out at large intervals - about once every 3 years.

Today, gas boilers to maintain a comfortable temperature in winter are widely used. On the market for such equipment, you can choose any model that is ideal for both the size of the consumer's wallet and his personal preferences. These can be wall-mounted and floor-standing units, single- and double-circuit, with forced and natural draft. However, the undeniable majority of people buy floor standing.

Advantages and disadvantages of floor heating elements

One of the advantages of gas floor heating boilers is ease of operation.

The design of gas heating equipment, which is mounted on the floor, is so perfect that it has not changed much since its inception.

The only exceptions are some modern improvements that have simplified the control over their work.

Today, almost 50% of the heating devices that are sold are floor-standing units. This is quite understandable.

The advantages of these devices:

• ease of operation. Some models can work for weeks without external control;
• high efficiency;
• can provide heat to the house, at the same time prepare the required amount of hot water;
• floor-standing appliances are suitable for heating both small houses and large structures.

For floor gas boilers, a specially equipped room or place with good ventilation is required.

The disadvantages include the mandatory presence of a chimney and a specially equipped room for a boiler or a place with good ventilation.

This equipment must be accompanied by permits and a certificate.

Classification of floor gas heaters according to structural material heat exchanger.

According to this parameter, boilers are divided into those containing steel and equipped with cast-iron heat exchangers.

Today there is a dispute which type of heat exchanger is the best, but the consumer still prefers despite the somewhat higher price over steel counterparts.

Why do people prefer cast iron over steel?

First, it is the service life. Cast iron products will last approximately 30 years, while steel products are operated for only 15-20 years. This is related not only to positive characteristics the metal itself, but also the design features of the product.

The service life in floor gas boilers made of cast iron is longer than that of steel ones.

So, cast iron heat exchangers are made with thick walls, which prevents burnout.

In addition, they are made from good brands material, which positive side proven themselves in domestic conditions of operation.

Secondly, cast iron is less susceptible to corrosion than steel. The metal of the heat exchanger begins to corrode when the temperature of the walls of the product drops below the point of condensation. In this case, moisture forms on the heat exchanger, which leads to corrosion.

Advice! The temperature of the heat exchanger walls must not fall below 60°C. Cast iron cools slowly compared to steel, therefore, even with a sharp drop in coolant temperature, the first option is easier to protect from destruction.

Cast iron heat exchangers may crack if transported incorrectly.

Thirdly, cast iron product has the form of sections, therefore, if it loses its integrity, it is possible to change not only the entire element, but only a separate part of it.

And now for the disadvantages. Cast iron heat exchangers fragile, because they can crack during improper transportation or from temperature changes. But today this shortcoming has been removed. Specialists add special additives to the alloy of iron and carbon, which made cast iron stronger.

Now he is not afraid of mechanical impact. In addition, models of such products can withstand temperature differences from 25°C to 30°C, and some of them up to 45°C.

Cast iron boilers have a powder-coated lining that retains its integrity for a long time and acts as an excellent decorating coating.

The specifics of gas boilers that do not depend on the consumption of external energy

A prerequisite for the operation of floor gas heating boilers is the presence of a gas main.

The presence of other sources of energy or electricity is not necessary. Indeed, today, along with improved models (equipped with pumps that circulate water forcibly, automatic control safe work, regulators temperature regime coolant and burner modulation), that is, volatile, there are non-volatile gas floor standing boilers. They are bought in those regions where there are interruptions in the supply of electricity.

Features of equipment that works without electricity

These boilers are economical in terms of fuel consumption.

In order for the boiler to work only on gas, modern manufacturers went two ways. In the first case, they completely simplified the design of the unit. That is, they made it more powerful, but without the automatic and electronic parts for managing work. With the help of such a device, the owner of the house can maintain the temperature in the house only at a certain level, that is, there is no automatic adjustment. The modulation of this parameter depending on the environmental conditions occurs only after intervention in the operation of the boiler from the outside.

The second way is a heat generator, which is able to independently generate energy for the functioning of the control system. In this case, in the flame gas burner thermocouple is located. When it warms up, it generates enough voltage for the control system to work above the valve. When the gas supply suddenly stops, the voltage drops, then the valve closes.

Important! Since non-volatile boilers do not provide for the presence of circulating sediment, the movement of the coolant is carried out due to natural circulation (expansion / compression of the liquid), therefore, similar heating systems should be organized with a slight slope of the pipes.

Modern manufacturer of gas boilers - Protherm. What are its advantages?

The products of the Protherm company (Slovakia) are popular in the domestic market for a reason. All this has been achieved thanks to performance characteristics equipment, its reliability and durability.

A wide range of outdoor, a variety of models and pricing, and configuration, a huge number service centers- all this had a positive effect on the demand for the equipment of this company.
