Today, gas boilers are often chosen for heating private houses. But the cost of such equipment is quite high, so everyone wants their device to work as long as possible.
From this article you will learn what the real service life of gas boilers is, what it depends on and how to extend it. We will also compare the standard service life of boilers from all popular manufacturers. As a result, you will be able to choose the optimal model for purchase, which will last as long as possible.
Boiler installation price category
As a rule, the retail price of a boiler is one of the indicators of its reliability.
Condensing heating systems belong to the most expensive category of heating equipment. With proper operation and regular maintenance, the declared life of such units is 30 years. This is due to the use of high-quality materials, which are necessary when obtaining thermal energy from combustible fuel and condensate.
Convection boiler equipment usually falls into the middle price category. The average lifespan of installations of this type declared by the manufacturer varies from 10 to 15 years. In convection heat generators, thermal energy is obtained exclusively through gas combustion, which leads to higher temperature loads on materials.
Design Features
If a single-circuit boiler is designed exclusively for heating, then a double-circuit boiler is also capable of providing users with hot water. Devices with two circuits can be:
- Flow-through. Water is heated in flow mode. The equipment is smaller in size, and the water is heated immediately when the tap is opened.
- Cumulative. There is a boiler - a built-in container for heating water. This is a more economical option.
One of the most popular models of the German brand is Logomax u072 183a. These are real mini-boiler rooms - energy efficient and safe. A high level of security is ensured by built-in sensors. If, for example, the burner goes out, the gas supply will be automatically stopped. There is an automatic system that maintains temperature stability. Filtration of incoming water is also provided.
Service life of a gas boiler in the heating system of a private house
Models of gas boilers in the budget price category , up to approximately 20-22 thousand rubles, have a service life of 7-12 years. As a rule, they use a steel heat exchanger, which, under the influence of corrosion, becomes thinner every year until complete depressurization occurs. Therefore, even if all other, less reliable elements are in good order, the resource is simply limited by the thickness of the steel heat exchanger.
In addition, inexpensive, especially domestic, boilers use less efficient and reliable alloys and materials; the models have mediocre build quality, usually lack protective elements, and have low-functional automation.
The average price segment , from approximately 25 to 40-45 thousand rubles, is characterized by a service life of at least 11-15 years. Such models often use a copper or cast iron heat exchanger, the service life of which is at least 20-25 years. Burners, connecting pipes and elements, automation boards are made of more expensive alloys, there are protective and insulating components and materials.
Automation in most models of middle-class gas boilers has a self-diagnosis function, overheating protection, pump blocking, frost prevention mode and other safety functions. In addition, most mid-priced models are produced in Europe, where standards of quality control and production technology are much higher.
The device of the expensive Buderus Logamax plus GB072-24K model: the use of the best materials, security and reliability of all components. A safety relief valve is already installed, and there is a condensate drainage unit.
Boilers of the highest price category , from 45-59 thousand rubles for models up to 24 kW, have the highest service life - an average of 12-17 years. These are models from German manufacturers (Vaillant, VIESSMANN, Buderus), some Japanese (Rinnai), French (De Dietrich). In such boilers, the best developments are used, the most reliable cast iron alloys (for example, gray cast iron), all components are reliably assembled, fixed and insulated. The highest quality control standards are applied to production. This explains the cost.
In addition to the price category, it is worth dividing the service life of floor-standing and wall-mounted boilers: in the latter, in most cases, it is shorter, since due to the suspended structure, which limits the weight of the boiler, they use lighter metals and other materials. Due to their more complex design, double-circuit gas boilers have a shorter service life.
About company
The Buderus company was founded in 1731. It has been on the domestic market since 2004. The company began with the production of equipment for boiler houses. The first gas heater was released in 1969. Today the Buderus brand is the property of the Bosch concern. The main activity is the production of boilers, boilers and control systems for heating equipment. The manufacturer produces heaters that operate on different types of fuel, as well as devices that can operate on different fuels. has 16 factories in Europe and Asia, as well as a wide network of distributors.
Service life of a wall-mounted boiler
This type of heating boiler is most in demand due to its low price and small size, but many buyers of such equipment do not know that they work much less than floor-standing options.
This is due to various factors:
- Almost all wall-mounted units are equipped with copper heat exchangers, in contrast to cast iron in floor-standing units. Copper makes the heating structure light, but it wears out quickly and requires a high level of purification of the circulating water. If this is not done, the copper will oxidize and the internal heating surfaces will become clogged with scale. From practice it follows that a copper boiler heat exchanger, even with good operation, can work for no more than 5-8 years, at a level of 12-18 for the cast iron version.
- A chimney with natural circulation cannot develop the power of the flame, so there is a temperature imbalance in the combustion chamber, leading to accelerated decommissioning of the unit.
- Wall-mounted boiler units generally have the lowest power and therefore operate with overload, which also significantly reduces the service life of a gas boiler in a private home.
Advantages
The German Buderus wall heater is a leader in consumer demand and has all the possible advantages of modern heating technology. Attachments:
- compact;
- silent;
- easy to operate;
- easy to use;
- energy efficient;
- they have a stylish design and an optimal price.
Service life of a floor-standing boiler
Floor-standing gas units last 5-8 years longer than wall-mounted ones. So, according to actual data, a steel heat exchanger can last 11-12 years, and a cast iron one can last 12-18 years.
Floor-standing devices practically do not function at full load, which prolongs the service life. And if the owner of a double-circuit heating boiler carefully carries out all routine maintenance and preliminary water purification, then such a gas boiler unit will serve him for at least an additional ten years. Many people remember Soviet cast iron boilers with a service life of 50 years.
The service life of a floor-standing gas boiler depends on the temperature conditions in the heating networks; at low temperatures, the flue gases cool down greatly.
At temperatures below 55 C, the condensation process begins in them, with the formation of acid, which penetrates the boiler heating surfaces and “eats away” everything in its path, from the chimney system to the firebox.
Therefore, if the manufacturer specifies a lower temperature limit for the return coolant, it must be maintained. In addition, when the condensation process occurs, it is necessary to additionally install condensate traps at the bottom of the chimney, which will significantly increase the service life of the floor-standing gas boiler.
Why you should not contact an unauthorized center
As a rule, there is nothing dangerous in contacting an uncertified center. It is likely that your boiler will undergo the required maintenance and, if necessary, even repaired. But practice shows that specialists of such services understand Buderus boilers very superficially and do not have expert knowledge. There is no guarantee that original components and spare parts will be installed.
In an authorized center you will not encounter such a problem - all ASC clients are protected by additional obligations from the Buderus brand. The manufacturer takes responsibility for the quality of work of the certified service center.
Boiler brand
Boiler units up to 24 kW in the price group from 40-60 thousand rubles. characterized by the highest service life from 12 to 18 years.
These include modifications from German companies: Vaillant, Viessmann Group and Buderus, Japanese Rinnai, French De Dietrich. Such devices use the best cast iron alloys, and the components are made using the latest innovative technologies.
The standard or manufacturer-declared operating life is calculated from the date of installation and first start-up of the equipment.
Installation features
Gas-fired heaters are easy to install. The connection and first start-up must be carried out by gas service specialists or workers with special permission - this is exactly what the instructions for users prescribe. Self-installation is prohibited. You should not try to connect and start the boiler yourself - gas workers will never give permission to operate it. Violation of this rule will result in loss of warranty. Setting up and servicing the equipment is also the responsibility of specialists - the user can fix only the most minor problems on his own. But there are requirements that are useful for owners of gas equipment to know about:
- The connection is made through corrugated pipes approved for use by Gostekhnadzor.
- Installation must be carried out in a room that complies with SNiP and PPB.
- When connecting to a chimney, the scheme “one device to one pipe” must be followed. For a cascade connection, a straight-standing coaxial chimney is required.
- Setup and first start-up are carried out together with a gas service inspector - he puts the appropriate marks in the technical documentation.
Even if you know how to connect and configure gas equipment, doing it yourself is strictly prohibited.
Maintainability of the heat exchanger
As noted above, the heat exchangers of modern gas boilers are made of: copper, stainless steel, cast iron. According to reviews, under the right operating conditions, the service life of a steel heat exchanger in a gas boiler is 15-20 years, and a cast iron one up to 30 years. The life of a copper coil is limited to 5-10 years.
In single-circuit heating heat generators, one coil is installed, which transfers the thermal energy obtained from fuel combustion to the coolant. Depending on the design, two-circuit boilers can have two heat exchangers (primary and secondary) or one bithermic.
- In the first option, the primary coil is responsible for heating the coolant and is installed in the upper part of the boiler installation (above the burner). The secondary one is responsible for creating the hot water supply.
- Bithermic has a “tube-in-tube” design. The coolant for the heating system moves in the space between the outer and inner tubes; Water flows through the inner tube of the heat exchanger to provide hot water supply.
Any heat exchanger is susceptible to scale formation. This is especially true for devices through which hard tap water circulates. The separate coil can simply be washed or the damaged section replaced.
In a bimetric heat exchanger, scale forms much faster than its separate counterpart. Deposits that appear in the inner tube of such a device are almost impossible to eliminate. Heat transfer will gradually decrease, which means that in order to maintain the desired water temperature, it will be necessary to increase the volume of fuel burned. Constant operation of the boiler unit in this mode will significantly reduce its service life.
It should be understood that repairing a bithermal heat exchanger is practically impossible; a complete replacement of the entire module is required. And this is a rather expensive process that can cost up to 50% of the initial cost of the heating installation.

Steam models
This category of boilers is designed to generate steam. Most plants that use steam in the process require high pressure. Therefore, the performance of such equipment consists of temperature and pressure indicators. For the most part, gas industrial steam boilers are units that, through fire tube structures, generate steam with a productivity of at least 0.25 t/h. Depending on the requirements of the enterprise, you can choose models with higher power. As a rule, the maximum reaches 55 t/h. Pressure indicators, in turn, can be up to 30 bar, and temperature conditions can be up to 300 ºС. Modern models are distinguished by their ability to operate on various types of liquid and gaseous fuels. When choosing, it would not be amiss to take into account additional equipment in the form of deaeration devices, dispensers and bubblers.
What determines the service life?
The service life of any gas boiler is traditionally influenced by a number of factors. Which it is advisable to take into account before purchasing equipment.
Let's take a closer look at the main points that affect durability:
- Type of gas boiler.
- Type of gas burner.
- Efficiency and functionality of electronics.
- Price category.
- Terms of Use.
- Incorrect commissioning.
- Poor quality installation of heating systems.
- Wrong choice of boilers.
In addition, each point contains a lot of significant nuances that should be dealt with in detail.
Gas boilers are always affected by a large number of negative factors that can significantly reduce their service life. Whether this will become a reality or not depends only on the owner of the equipment
Factor #1 - heat exchanger material
Modern gas boilers are wall-mounted or floor-mounted . The first ones are compact and lightweight, so they are convenient to use in limited space. The second category of equipment is massive and large.
The features listed above are not just boiler characteristics, but factors that directly affect service life.
The reason is that developers are achieving lightness and compactness of mounted boilers by reducing the weight and dimensions of such an important design element as heat exchangers . As a result, the walls of the bodies of mounted models are thinner and prone to overheating, have less resistance to corrosion, and do not cope effectively with loads due to changes in coolant pressure.
In order for gas equipment to serve for a long time, the necessary installation and maintenance work must be carried out by specialists. This will reduce the likelihood of errors, and therefore extend the life of the boiler.
In addition, different materials are used for the manufacture of heat exchangers for both types of equipment. copper is most often used for mounted boilers - as the lightest metal of all suitable for these purposes.
And this is the only advantage, because the performance characteristics of this material are close to mediocre. As evidenced by its tendency to oxidize and not the best protective qualities against pressure changes and their consequences.
Quite often, floor-standing boilers (less often wall-mounted) are equipped with stainless steel . But even with the same manufacturing material, the reliability of the design is not always the same - the walls of heat exchangers of ground-based products are usually much thicker, which extends the service life.
The most reliable metal used for the manufacture of heat exchangers is cast iron . It is resistant to corrosion, and if it is protected from significant pressure drops in the heating system and the resulting water hammer, then this metal will provide the longest service life to heating boilers.
When using a boiler, a significant amount of combustion products is always deposited on the surface of its heat exchanger, which must be removed. Otherwise, they can lead to overheating and breakdowns. And replacing this unit will not always be rational. For example, the cost of a bithermic heat exchanger can be an impressive 50% of the price of the entire gas boiler
The listed features lead to the fact that the difference in service life can be impressive.
Factor #2 - type of gas burner
In domestic boiler installations, two types of burners are used: atmospheric and inflatable. Atmospheric, which are installed in units with natural flue exhaust in open fireboxes. These burners take combustion air directly from the room in which they are located.
Such a smoke exhaust system is structurally very complex, its operation is not stable and depends on many factors, for example, on the speed of the wind, which can clog the smoke exit from the chimney.
The poor quality of the chimney exhaust leads to the accumulation of soot in it, which further reduces the speed of the flue gases and violates the design temperature regime of the boiler, leading to premature burnout of its structural elements.
Inflatable or turbocharged burners are installed in modern closed-type devices with a coaxial chimney and do not have these disadvantages.
The speed of movement in the unit is set by a fan, air is taken from outside the room through the outer channel of the coaxial pipe, and flue gases are emitted into the atmosphere through the inner channel.
The operation of such a fan can be modulated to suit different boiler outputs from 30 to 100%, which significantly extends the service life.
Factor #3 - Electronic functionality
Today, the service life of modern gas boilers used in heating systems directly depends on their automation.
Because electronics performs the following functions:
- selects optimal operating modes, which reduces operating hours and loads;
- performs self-diagnosis;
- prevents emergency situations that often become causes of breakdowns (for example, overheating);
- protects circulation pumps from blocking.
Automation of a gas boiler allows you to perform a number of other important tasks. Which, ultimately, extends the service life, preventing breakdowns.
The more advanced the electronics, the more functions it performs. And the likelihood of errors and failures leading to negative consequences is lower.

Factor #4 - boiler price and brand
In the field of gas heating equipment, there is a well-known rule - cheap cannot be good . Therefore, it is more likely that products from well-known European and Japanese brands will withstand many years of operation without breakdowns.
Chimneys must be checked annually, before the start of the heating season. But many owners, as well as inspectors, approach this requirement formally. The result of inaction can be seen in the photo, which shows a chimney pipe almost completely clogged
The reason is that the products of these manufacturers are designed to meet the stringent requirements of domestic markets. And high-quality materials are used in production. In addition, companies with a good reputation have established quality control , which reduces the number of boilers that do not meet the requirements leaving the factory.
Factor #5 - equipment operating conditions
The quality of the coolant has a significant impact on the service life. So, if the water is hard, highly acidic and contains various impurities and foreign particles, then there is no doubt that in a few years the heat exchanger channels will be clogged with scale or corroded by corrosion. Which will lead to early failure of the heating boiler.
Equally important to ensure longevity is the quantity and quality of air used to burn the gas. We discussed the reasons for this in detail above, in the paragraph “Type of gas burner”.
The main way to extend the service life is regular maintenance of boilers. This procedure requires special skills and tools, so not everyone can do the necessary work on their own. It is advisable to conclude a maintenance agreement with the gas company.
Despite the extra costs (payment for the services of a technician servicing the boiler), you should not save on maintenance, since maintenance can not only extend the service life, but also guarantee the safety of those living in the house
The following points can also lead to premature wear:
- increased humidity in the room where the heating boiler is installed;
- high/low temperatures, their differences.
Moreover, all of these factors actively influence durability, both during operation in cold weather and after the end of the heating season.
Factor #6 - errors during system installation
Low-quality installation of boiler units will lead to the fact that it will not be able to operate at stable conditions. In this case, air can collect inside the heat exchanger, and dust can be deposited on the surfaces of the burner device, which leads to a high level of wear.
A frequent root cause of unit malfunctions is considered to be incorrect installation of batteries and other elements of the heating network:
- If the batteries are installed with a counter-slope, air collects in them, which causes corrosion of the internal heating surfaces, both in the heating network and in the boiler.
- An incorrectly installed air vent will not perform its functions, the coolant will not circulate in the operating hydraulic mode, disrupting the temperature regime of the boiler and overheating the heating surfaces.
- Incorrect slopes in the natural chimney system will contribute to soot deposits in the internal channels, a decrease in the size of their cross-section, a drop in the aerodynamic speed of the flue gases, which will contribute to overheating of the firebox and heat exchanger, as well as the possible release of carbon monoxide into the room.
Factor #7 - wrong choice of boiler
Lack of productivity leads to increased loads on the heat exchanger, burner, pumps, which, in turn, leads to their subsequent wear.
The durability of gas boilers largely depends on their structural reliability. The stock of which can only be provided by well-known manufacturers with a good reputation
An equally problematic issue is excess power. Because of which boilers often turn on/off. And unsteady operating conditions are a direct path to premature wear.
We recommend that you familiarize yourself with the criteria for choosing the best gas boiler.
Factor #8 - Automation
More expensive models of gas boilers are equipped with multifunctional automation, which will not only promptly warn about the condition of the boiler, but will ensure the most efficient operation of the boiler. By preventing emergency situations, automation with the functions of self-diagnosis, prevention of overheating and freezing, gas control, auto-ignition, and protection against blocking of the circulation pump significantly extends the life of the gas boiler.
However, for the correct operation of such automation, a voltage stabilizer and a UPS (uninterruptible power supply) are recommended.
What you need to pay special attention to when choosing a gas boiler
With such a variety of different models, it is difficult to make a choice in favor of a specific one. But price should not be the main selection criterion. For effective operation, a modern boiler must meet a number of basic requirements: 1. No Frost system, which prevents freezing of the main components of the boiler, and in an improved form, the general heating system. 2. Improved or universal type of burner - conventional ones are not very economical. 3. Basic equipment should include: 3.1. A membrane-type expansion tank with a volume of at least 7% of the total volume of the heating network. 3.2. Circulation pump. 3.3. A set of sensors for monitoring the temperature of the coolant in the boiler, on the heating radiators, and preferably an air temperature control sensor. 4. Boilers from imported manufacturers must be adapted to the gas and electrical networks of Russia. 4.1. The presence of an automatic spotter on a piezocrystal or electric spark is mandatory. It is advisable to have a heating element with an incandescent element, which will make the operation of the boiler with low-calorie or unrefined fuel more economical and safe. 4.2. Products must be certified. 4.3. The range of operating pressure of gas and water is preferably the widest. 4.4. Built-in overvoltage protection system. Otherwise, you will have to buy and install an expensive filter. The possibility of connecting via a UPS with an output to an external battery is welcome.
Only after all the listed components are available and the requirements are met can the price of devices of comparable power be compared.
Each person chooses the best for himself. Each buyer puts their own meaning into the concept of “best”. Reliability? Safety? Price? Appearance? All this can be correlated with gas boilers. What are the best gas heating boilers? It all depends on what functions are your priority.
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 be suitable.
It is necessary to think about what type of boiler is suitable for housing: floor-mounted or wall-mounted. If you need a high-power boiler, then it is best to choose a floor-standing type of equipment. The disadvantage of such a unit is that it requires a separate room. For a regular kitchen, a more compact option is suitable - a wall-mounted boiler.
It is worth considering such characteristics 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 outside. It should also be taken into account that their body overheats, so a boiler with an open combustion chamber should not be installed next to meters, wooden furniture and curtains. Boilers with a closed chamber have a coaxial pipe in their structure, which absorbs air from the street and exhausts it back. Such a boiler is an economical option, since gas and air are uniformly mixed in the coaxial pipe, so the boiler body with a closed combustion chamber does not overheat.

The modern market presents a choice of gas heating boilers to suit 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.
Device
The main components of Buderus wall-mounted boilers are:
- Gas-burner.
- Heat exchanger (bithermal or conventional type).
- Turbocharger fan.
- Circulation pump with automatic air removal.
- Secondary plate heat exchanger made of stainless steel.
- Three way valve.
- Control equipment for pump and fan operation.
- Control board with sensor system.
- Connecting pipelines, connecting pipes.
The coolant enters the primary heat exchanger, where it is heated to the maximum possible value.
Then it goes to the secondary heat exchanger, where excess heat is transferred to prepare hot water.
After this, in a three-way valve (mixing unit), it receives the set temperature by mixing a certain amount of colder return flow, after which it exits into the heating circuit.
All work is controlled by a system of sensors that send signals to the control board. The occurrence of problems is immediately detected, the owner is notified by displaying an error , and in difficult cases the boiler operation is blocked .
Recommendations for extending service life
To ensure that the standard service life of household gas boilers, established by the manufacturer, is not significantly reduced due to the problems listed in the article, it is necessary to perform a number of operations.
Firstly, even before purchasing a unit, you should determine its optimal power . The reserve should be 10-15%. That is, if a heating capacity of 13 kW is sufficient for heating, then it is more advisable to buy a boiler whose specified parameter will be around 15 kW.
Secondly, before connecting the unit, it is advisable to check the electrical network and heating system . And, if shortcomings are identified in the form of pressure and voltage drops, then they should be eliminated. In addition, it is necessary to flush radiators and pipelines. And also take care of the presence of grounding.
Replacing an old product with a new one may not solve all heating problems. Therefore, before installation, you need to take care of a high-quality check of smoke removal systems, heating, and electrical networks, and eliminate any identified deficiencies
Thirdly, it is imperative to check the coolant . And, if the water is hard and contains impurities, then care must be taken to install filters in the system with a sufficient degree of purification, which can be coarse or fine. It is often necessary to use both types of equipment. Magnetic filters effectively remove metal particles.
Fourthly, you should not skimp on installing the boiler ; it must be done by qualified specialists. From the moment of test start-up of the unit, a voltage stabilizer should be used to protect it.
It is also advisable to use:
- uninterruptible power supply - in the event of a power outage, this device will make it possible to eliminate system failure;
- dielectric inserts - they will eliminate the interaction of electric current with gas and the consequences of this.
Fifthly, it is advisable to use boilers regularly . That is, do not turn them off when leaving for work or even for a long absence.
The service life of the boiler will be extended by using it in the off-season. Why do you need to choose the most economical mode?
Sixthly, do not neglect boiler maintenance - this is the most important measure to extend their service life. According to the governing documents, it must be performed before the start of each heating season. But it is better if the owners carry out the necessary procedures 2 or even 3 times a year.
And not formally, but with cleaning of boiler channels, pipelines, radiators, heat exchanger surfaces, burners. As well as replacing filters, checking the functionality of the mechanics and electronics of the units.
Seventh, you should promptly respond to any warning signals from the electronics during operation.
List of works
To understand what exactly should be cleaned, checked and adjusted in the boiler, and with what frequency, just look at the instructions and technical documentation, which must be included with the boiler when purchasing it. These documents contain a complete list of components and elements involved in the equipment, maintenance requirements and the frequency with which the condition should be checked, service performed and settings updated if necessary.
You absolutely cannot rely on this information to clean a gas boiler yourself. This information gives a clear idea of what to expect from the service company with which you are about to enter into a contract for servicing gas equipment.
The works are divided into three groups:
- Regular work carried out before and after the start of the heating season, preparing the boiler for summer inactivity.
- Major maintenance. Work carried out every few years and aimed at servicing elements with an initially intended long service life (flushing the heat exchanger, replacing seals and valves, maintenance of fans, etc.).
- Repair in case of breakdown. The procedure for actions and mandatory work in the event of an emergency situation, breakdown or consequences of external factors.
Seasonal service regulations
Before the start of the heating season, the boiler should be brought into proper working order and the operation of the sensors responsible for safety should be checked. Only after this the boiler is turned on for operation.
If the manufacturer allows routine maintenance to be carried out only once a year before start-up, then in addition to commissioning work, the main elements of the boiler are cleaned, with the exception of flushing the heat exchanger and a complete overhaul of the control units. If maintenance (maintenance) is carried out after the season, then cleaning is reserved for this stage.
Required list of works:
- General inspection, removal of dirt from internal and external surfaces.
- Cleaning filters (air, gas, coarse water filters).
- Cleaning and checking the burner.
- Cleaning the fire section of the combustion chamber.
- Checking the tightness of internal gas channels.
- Checking the ignition electrodes (piezoelectric element and burner).
- Test and diagnostics of the electronic control unit.
- Test and diagnostics of sensors and automation responsible for safety.
- Adjustment of boiler parameters, combustion settings. The process is accompanied by analysis of exhaust gases. Based on the composition and concentration, the master judges the accuracy of the boiler settings.
- Checking the condition of the shut-off valve.
- Checking the supply gas pipeline in the area from the main line to the gas equipment.
- Checking and adjusting the pressure in the expansion tank.
Major renovation
In addition to routine maintenance carried out every season, during a major overhaul of a gas boiler, elements with a limited warranty period are replaced, the internal surface of the heat exchanger, seals and valves are cleaned. The main task is to replace elements that are not subject to maintenance during routine maintenance, but still have a service life.
In case of breakdown
In an emergency situation when a breakdown occurs during operation, it is very important to respond to the problem as soon as possible and return the boiler to working condition. If breakdowns occur, they occur only during the heating season, for example, if the boiler operates for a long time at maximum power during the coldest period of the year.
At this time, it is extremely difficult to find a specialist for quick repairs, but with a service agreement, all you need to do is leave a request so that the repair team can arrive in a short time to fix the problem. Since the service center keeps records of boilers, a specialist arrives at the customer with a set of necessary tools and spare parts for a specific model of gas boiler.

Internal structure of boilers
