The actual service life of a gas boiler: what determines the lifespan of a floor-standing or wall-mounted boiler unit when used in the heating system of a private home

…

Any modern household heat generator is a fairly technologically advanced and expensive device that has its own service life. In this publication, we will look at what factors influence the service life of a gas boiler, and what you should pay special attention to when choosing this equipment.

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.

Electronic components and power supply

Today, all models of gas heating equipment present on the domestic market are equipped with automation, which can be non-volatile or require connection from a household AC network. One of the factors that leads to breakdowns and reduced service life of gas boilers is the unstable operation of electrical networks. A normal power surge can easily damage the elements of the control unit, controller, ignition system, gas valve, and other electronic and electrically controlled components.

Advice: If you want the lifespan of your boiler system not to be lower than that declared by the manufacturer, then choose models with a built-in voltage stabilizer or use an uninterruptible power supply in the device’s power supply circuit.

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.

How to choose power?

All types of heaters are produced in a wide power range; each buyer can choose the option that best suits the heated area. When choosing power, take into account the following factors:

• average winter temperature;
• features of the walls - their thickness and material;
• windows - their number, type and size;
• ventilation and other nuances.

To simplify the choice, standards are calculated for consumers, W per 1 m²:

• For the middle band - 100.
• For Siberia – 150.
• Polar region - 200.

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:

1. 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.
2. 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.
3. 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.

How to connect the boiler?

For piping, only branded components and equipment compatible with Buderus heaters are used. To facilitate the connection of the BKN - indirect heating boiler, single-circuit versions have valves. Supply and return are connected in accordance with the connection diagram specified in the operating instructions. You can connect containers with a volume of 60, 80, 100 and 120 l. Moreover, this can be done even in winter - there is no need to turn off the heating to connect the BKN.

What should the room be like?

Regardless of what brand of equipment is installed and who its manufacturer is, the same requirements are imposed on the premises:

• Natural ventilation is needed.
• Minimum height – 2.2 m.
• Area – from 12 m²
• The doors should not have a threshold. The gap between the door leaf and the floor surface is 1-2 cm.

For turbocharged versions, a reduction in area to 8 m² is allowed.

How much does a Buderus boiler cost?

The price of German gas heating equipment was significantly reduced due to the location of production facilities in Russia. For example, the Logamax U072K wall-mounted device today costs between 30-35,000 rubles. Floor-standing model Logano G124 WS RU - about 70,000 rubles. Such prices and brand recognition predetermined the popularity of Buderus products among Russian consumers.

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.

Single and double circuit boilers Buderus

This is an important point in the process of choosing a Buderus gas boiler. One contour model is designed only for heating the room. The two-circuit system additionally provides the home with hot water.

The difference between equipment with two circuits:

1. Flow model. Differs in reduced size. The water heats up after opening the tap. This does not require a special container.
2. Cumulative modification. Based on a boiler for storing and gradually heating water. Despite the serious drawback - the heating process lasts 1 - 3 hours, this modification is considered more economical to operate.

It is the storage versions of 2 Buderus contour boilers that are popular in Russia.

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.

What to do if there is no ACC nearby

There are more than 300 companies in the developed network of Buderus ACC. And yet, sometimes it turns out that there is no authorized center in the client’s city. In this case it is necessary:

• find the nearest service center on the website buderus.ru;
• contact its employees through the organization’s website or by phone and submit a request for maintenance or repair.

According to Buderus regulations, ASC specialists who have received an application for warranty repair or service of gas boilers are required to go to the site within 24 hours, regardless of its remoteness. In this case, the repair team’s visit is not paid if the warranty case is confirmed. If the warranty terms do not cover the malfunction, the service is paid at the service center rate.

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.

Intensity of work and nuances of operation

Before purchasing, the necessary calculations regarding the power of the boiler system must be carried out. As a rule, in a design organization, specialists “throw on” 15-20% of the power to reduce the load on the boiler at the time of peak loads. If you choose a boiler unit yourself, then often, in order to save money, you purchase a model whose power “butt-butt” corresponds to the calculated one. Constant operation at maximum load significantly reduces the service life of a gas boiler , so when purchasing a device, you should ensure a power reserve of at least 20%.

Corrosion can destroy a copper heat exchanger within a few years. To increase its service life, you need to get rid of the presence of air in the heating system, since oxygen is a powerful oxidizing agent. To do this, you should use air vents, regularly identify and bleed air from the radiators through Mayevsky taps. We recommend watching the video.

In it, a specialist talks about the relationship between the service life of the boiler system and corrosion in various types of heating systems.

The service life of the boiler unit is affected by the pressure in the heating and water circuits. The stability of this parameter in the heating system is ensured by proper selection of the volume of the expansion tank. Due to low water pressure, the volume may not be sufficient for continuous operation of the burner. Having reached the required temperature, the burner will periodically turn off, and when the temperature drops, it will turn on. When operating for a long time in this mode, the resource of the device is exhausted much faster, which affects the life of the entire boiler unit.

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:

1. Type of gas boiler.
2. Type of gas burner.
3. Efficiency and functionality of electronics.
4. Price category.
5. Terms of Use.
6. Incorrect commissioning.
7. Poor quality installation of heating systems.
8. 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.

We recommend: Operating principle of atmospheric gas boilers: advantages and disadvantages of heating equipment

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:

1. 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.
2. 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.
3. 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.

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 .

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.

How to identify a malfunction

Despite the use of advanced technologies, sometimes problems occur. They are detected by sensors and self-diagnosis.

If a malfunction is detected, the system will display the corresponding code.

• What if the burner doesn't light? First, you should check whether the heating or control system starters are turned on. But it is possible that the circuit breakers of the protection system have failed, or that the regulators or temperature limiters of the equipment have broken down. It is possible that the gas smoke control equipment has failed;
• If the burner is on, but an error code appears? As a rule, the problem is a closed valve or the presence of air in the gas pipeline. To neutralize, it is necessary to open the valve to allow air to escape;
• The burner lights up, but there is a signal of no ionization current? It is worth checking the condition of the contacts, sometimes they oxidize. But it is not uncommon for the connection of electrodes of type N and L to be mixed up. Although it is possible that the electrode may short-circuit to the boiler body. If everything is checked, but the reason is not clear, we can only assume a breakdown of the burner automation;
• The burner is on, but the display shows an error of 1.5 mA? Perhaps the reason is the appearance of soot on the electrode or the oxidation process. Therefore, it is worth cleaning the electrode;
• If there is a boiling process in the heat exchanger? Most likely, a large layer of scale has formed or there has been a critical decrease in the amount of coolant in the system.

Now we have realized the features of Buderus boilers and identified the reason for their popularity in Russia - the quality of German assembly and reasonable cost.

We understood the intricacies of installation and the causes of popular problems. This will help you responsibly select the appropriate model and subsequently operate it effectively.

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.

Advantages and disadvantages

The advantages of Buderus wall-mounted boilers are:

• High build quality, reliability of units and parts of the unit.
• Easy to control, convenient display with intuitive symbols for operating mode adjustment controls.
• Possibility of remote control of the system from anywhere in the world.
• Compact, able to fit into the interior of a small kitchen.
• Relatively low cost compared to similar models from other companies.

There are also disadvantages:

• Boilers are energy dependent, require stable voltage, need to install stabilizers.
• Some parts are made entirely of plastic, which makes them short-lived under harsh operating conditions.

NOTE!

The disadvantages of Buderus boilers are not decisive and are completely offset by the undoubted advantages that all models have.

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.

In addition to the end of its service life, possible reasons for replacing a heating boiler can be changes in electrical voltage and water. In Russia, water has significant hardness. On average, its indicator is 7.0 mEq/l, when in European countries it is 2 times less. Even harder water is in the Moscow region (10 mEq/l). It can damage a heating boiler in just 1 season.

You should sound the alarm when you smell soot or hear extraneous noises. There are also different temperatures in the rooms. Repairs often cost significantly more than purchasing and installing a new one.

Who replaces heating boilers?

It is strictly prohibited to replace heating boilers yourself. The law provides for administrative penalties, and in some cases criminal ones. After all, the consequences can become irreversible.

Boilers can only be replaced by companies with appropriate specialization and qualified personnel. To implement it, it is necessary to obtain permits from the gas distribution organization, and in some cases, an additional project with approval. If approval is received, then the contractor’s documents and a chimney inspection report must be provided to the gas service. Additionally, certificates confirming compliance with the safety level may be required if an imported boiler is installed.

Therefore, you should trust the professionals - the company DESIGN PRESTIGE LLC . Replacing a heating boiler, the cost of which will please you, will be carried out promptly and competently, both technically and documented.
