Maintenance of a wall-mounted gas boiler. Service and maintenance of gas boilers in the Unified Service Center

Modern gas boilers have economical fuel consumption, high performance and reliability. Therefore, an increasing number of consumers are choosing gas-fired boilers for heating private houses and non-residential premises. Often, the owners of the heating system forget that without proper maintenance, the efficiency, safety and efficiency of the boiler is significantly reduced.

Maintenance of a gas boiler allows you to:

• eliminate the risk of breakage during the heating season;
• significantly extend the life of the unit;
• avoid financial costs for repair or replacement;
• ensure its correct and continuous operation.

Since a gas boiler is equipment that uses both gas and electricity for operation, it is very important to identify damage to elements or wear of parts of the heating system in time to eliminate the risk of gas leakage, fire or fire. Compliance with the rules for the use of gas equipment and regular maintenance will help to avoid costly overhaul or replacement of the boiler in the future. In addition, maintenance allows you to eliminate the risk of operating a faulty heating system, helping to provide your home with high-quality heating for the entire life of the boiler.

Why do you need boiler maintenance?

Let's take an example of how, without maintenance, the boiler begins to consume more gas and heats the room worse and worse over the years. It is known that the heat exchanger of a gas heat generator is subject to corrosion and scale formation. If the pipes are not washed and cleaned in a timely manner, then scale and pollution become an obstacle to the required heat exchange.

The power of the boiler decreases, and with it the temperature of the coolant increases. So, gas consumption increases, and the boiler unit ceases to be efficient and economical. Obviously, regular maintenance will help to eliminate such problems with the boiler. Checking the performance of the boiler is also necessary for the reason that over time, the components and parts of the heating system wear out and require replacement. A typical inspection by a licensed service center includes a visual inspection of parts and components of the system for damage and wear, and, if necessary, adjustments or repairs by specialists.

The main reasons for the breakdown of a gas boiler

The breakdown of the gas boiler occurs for such reasons as:

• a marriage that was not found in production during testing;
• improper operation and lack of proper care;
• lack of required maintenance.

If you ignore the signs of a decrease in boiler efficiency and do not check, then users risk being left without heating during the heating season due to its breakdown. On the contrary, timely maintenance and repair of a gas device is a condition for the safe operation of equipment, as well as the ability to reduce heat loss, bring the boiler efficiency back to normal, increase the efficiency of the unit and solve other problems.

Types of boiler maintenance work

Servicing and testing of heating installations is carried out by commissioning operators from company service organizations. In order to maintain a guarantee for boiler equipment from the manufacturer and reduce operating costs during the operation of a gas boiler, you cannot trust the installation, repair and replacement of the boiler and its elements to a third-party non-specialized company. You should not choose dubious companies without a license and permission to carry out installation and operational activities, even if they promise to inspect the boiler cheaply.

Maintenance work is divided into 3 types:

1. Regular work. According to the regulations, each season is carried out before and after the start of operation of the boiler, in order to prepare for summer inactivity in order to eliminate the risk of corrosion and save the resource of components and components. The work includes: inspection and cleaning of the main elements of the unit.
2. Capital service. Deep check, which is performed according to the schedule, every 3-5 years. The work includes: flushing the heat exchanger, replacing valves, seals, checking fans and other elements.
3. Current repair in case of unexpected breakdown. A boiler that has been operating for a long time at maximum power can fail for various reasons. In order not to be left without heating and to fix the problem, you should leave a request with the service department with which the service contract has been concluded.

Only a specialized service organization can provide a guarantee for the work performed, order new parts for warranty replacement, as it has all the necessary resources to keep the boiler in excellent condition. As a rule, the personnel and service technicians are qualified and experienced, and most importantly, they take a training course from the manufacturer of gas devices and have the necessary repair and diagnostic equipment for the customer's gas boiler model. So, at the request of the user or according to the plan of checks, service specialists come, check the condition of the boiler, perform service and update the unit settings if necessary.

What is included in the overhaul of gas equipment?

Capital maintenance of the gas unit includes cleaning of the combustion chamber, burner and other elements. Connections are checked to eliminate the risk of gas leakage, pressure in heating tanks, burner operation parameters. Mud collectors and filters are cleaned, air sensors are purged, and defective parts are replaced. The foreman assesses the condition of the smoke and ventilation ducts, as well as the tightness of the units.

Thus, a typical overhaul of gas equipment includes a performance check, replacement and repair of such elements as:

• burner. Work on purging the air and flame presence sensor, cleaning the igniter electrodes and washers, removing carbon deposits from the chimney, washing and replacing filters.
• automation system. Checking the units responsible for fuel consumption, operating mode and safety of the unit. Proper setting of the automatic mode helps to reduce gas consumption by up to 25%.
• gas channels. Work on cleaning the pipes through which the energy carrier moves. Checking the solenoid valve blocking the gas supply for leaks.
• checking the quality of all gas supply connections. Elements should be assessed for corrosion and tightness.
• the combustion chamber. Cleaning of parts in contact with the flame of the burner.

Obviously, the warranty service of gas equipment helps to prevent serious damage. The terms of inspections and overhaul services are set by the manufacturer. As a rule, after the end of the warranty period for the operation of the boiler, 6 months must pass before the first check by a specialist.

Frequency of inspections of heating installations

Despite the fact that gas equipment manufacturers produce boilers with increased durability and wear resistance, technical inspections cannot be neglected. Requirements for maintenance and frequency of inspections of heating installations are indicated in the technical documentation for the boiler. Thus, the terms of inspections and inspections are indicated by the manufacturers in the operating manual and in the contract between the user and the service representative. For each model range of gas equipment, their own terms are set.

Inspections as part of the service must be carried out every season. To prepare for the heating season, before starting the boiler, they bring the boiler into proper working condition, clean the main elements and check the sensors that are responsible for safe operation. It should be noted that the service company may change the timing of inspections, taking into account the characteristics and actual characteristics of the gas or heat carrier used in the boiler. Obviously, boiler maintenance is a mandatory prevention of equipment failure.

Maintenance of the gas boiler must be done regularly. During the annual inspection, failures in the operation of automation, the safety of insulating materials, and the tightness of assemblies and pipes are revealed. Thus, the safety of the equipment is guaranteed, savings are achieved due to the fine adjustment of the gas flow. In this material, we will talk about the actions that must be performed for competent prevention of a gas boiler. Consider the example of a wall model. Most often, it is wall-mounted boilers that require detailed maintenance.
The following maintenance steps can be defined:

• shutdown of gas, water and electricity
• coolant drain
• turbine maintenance
• cleaning the heat exchanger
• cleaning gas burners and electrodes
• boiler cleaning
• expansion tank check
• checking flow sensors and filters
• gas pressure adjustment
• connection and testing

Before starting the maintenance of the boiler, it is worth making a visual inspection of the shut-off valves for supplying and discharging water. Perform a voltage test. Check the condition of the gas inlet and its shut-off valves.

Initial disassembly of the gas boiler

In the absence of damage, you can proceed to shutdown, partial dismantling of the boiler, draining the water and starting preventive maintenance. After removing the front panel, check the thermal insulation of the connecting pipes and the expansion tank. Do not allow freezing of pipes supplying still cold coolant.

Turbine maintenance

Gas boiler turbine

The smoke exhauster ensures proper removal of carbon dioxide, soot and smoke after the combustion of the gas mixture. After dismantling the fan, it is worth checking the chimney pipe leading to the street for clogging. The fan must be cleaned of dust and the shafts must be lubricated. The condensate collector leading to the turbine must be airtight.

Cleaning the gas burner chamber and heat exchanger

gas boiler burner

After removing the cover, we clean the external fins of the heat exchanger from combustion products with a coarse brush. A well-cleaned heat exchanger provides uniform heating of water or other heat carrier and prevents local overheating.

Using a soft copper brush, you need to remove soot residues from the ignition electrodes and the ionization sensor that are in the chamber and wipe them with isopropyl alcohol. Finally, you need to check the gap from the electrode to the burner, which should be about 4 mm.

Chemical descaling

There are operating conditions (they are indicated at the end of the article), under which it may be necessary to service the gas boiler in the form of cleaning the heat exchanger from scale. In this case, the supply pipes are unscrewed and completely. For chemical cleaning, it must be filled with a solution of hydrochloric acid, which dissolves blockages. After 10-15 minutes, drain and rinse with running water. If during washing there are still difficulties with the passage of water, the cleaning process should be repeated.

Cleaning the inside of the boiler

With the help of a vacuum cleaner, we finish cleaning the combustion chamber and clean the rest of the internal volume of the gas boiler. Next, wipe all surfaces with a damp cloth. This prevents dust accumulation and possible fire if the boiler has not been used for a long time.

Expansion tank pressure adjustment

During the production of a gas boiler, nitrogen is pumped into, but during operation, manufacturers are allowed to pump with ordinary air. The expansion tank is necessary to compensate for the excess pressure that occurs as a result of heating and cooling of the coolant. In addition, it has the function of protecting against water hammer in the heating system.

For complete prevention of a gas boiler, using a pressure gauge, you need to measure the pressure in the expansion tank. For most wall-mounted boilers, the pressure required for operation is 1 bar. The exact figures must be clarified in the documentation for the boiler. In the event that the pressure is not enough, it is required to pump nitrogen or atmospheric air there using a compressor. In case of excess pressure, it is necessary to bleed the excess through the valve.

Cleaning filters

incoming . If water is used as a heat carrier, then the flow often contains fine sand, silt, scale, rust or metal shavings. Dirt entering the system may interfere with the inlet flow sensor, clog the heat exchanger, etc.

The filter and flow sensor can be cleaned with normal running water and a hard bristled brush. Further, before reassembly, to soften the sealing rings that prevent leakage, they must be treated with silicone grease to achieve a tight connection.

Filling the system and checking

After installing the filter, you need to fill the system with coolant, for this we open the shut-off valves. After filling the boiler, we carefully check the entire system for possible leaks and turn on the idle run of the boiler, without gas. We check the regular operation of automation and the absence of error signals.

Gas pressure regulation

Measuring and adjusting the minimum and maximum gas pressure will allow not only to achieve the correct operation of the boiler, but also to save money. The exact pressure range is indicated in the instructions. For wall-mounted boilers, it is at least 2 mbar. The maximum pressure is 13 minibar.

If there are no errors, start the gas boiler and open the gas valve. Using a differential pressure gauge, we measure the minimum gas pressure in the system. To measure the maximum possible pressure, turn on the boiler in the “chimney sweep” mode and check the pressure in this mode. If necessary, adjust the pressure to passport values.

Check and start

After completing the maintenance of the gas boiler, we carry out a thorough check with a gas analyzer of all possible leaks. We close the protective cover and test the operation of the equipment in all possible modes. In addition, it is worth conducting additional briefing on the topic of safety and technical conditions for the operation of a gas boiler.

Importance of correct gas pressure setting

When the pressure drops below the permissible values, the boiler automation is not able to accurately adjust the heating temperature and works at maximum values. Electronics opens the maximum pressure and heats the boiler to the required temperature, but due to insufficient pressure, it is impossible to maintain the desired temperature. Automation shuts off the gas and, after reaching the minimum allowed temperature, again heats the boiler to the maximum in the maximum possible mode.

If the gas pressure exceeds the nameplate values, the flame height is too high. This can lead to premature burnout of the heat exchanger, which is not designed to work in this mode.

Compare this with normal operation, in which the temperature is smoothly brought to the required values, after which it is maintained at a minimum gas flow. In this case, there is a decrease in gas consumption due to the smooth dynamics of heating and cooling.

Is it necessary to chemically clean the heat exchanger inside?

Under normal operating conditions, no. The service life of the heat exchanger is about 6-7 years and it is easier to make a preventive replacement after this time. Annual dismantling and reinstallation will only increase the risks associated with the possible destruction of connections and the risk of subsequent fluid leakage.

However, there are reasons why it is worth performing an annual chemical cleaning. This is very hard water, which contains too many mineral impurities. The scale layer builds up too quickly in the heat exchanger. Because of this, there are difficulties associated with insufficient heating of water. With prolonged operation in such conditions, the heat exchanger generally stops passing enough liquid, overheats, burns out and the boiler fails.

How often should the boiler be serviced? Regularity of prevention

An audit of the gas boiler must be carried out at least once a year, before the start of the heating season. Why is it necessary to regularly service gas boilers? The answer is simple, it is necessary for a reliable and uninterrupted supply of hot water. Let's try to figure out what can happen if you do not conduct an annual audit of the gas boiler.

• Over time, connections become more and more brittle, insulating materials wear out and cannot provide a sufficient degree of sealing. This applies to both coolant and gas.

• Excess dust and burning on the turbine impeller leads to its wear and premature failure.

• Insufficient or excessive pressure in the expansion tank leads to sudden pressure surges, which leads to the destruction of joints, seals and hydraulic systems.

• A clogged filter may cause the water supply to stop. Also, poor filtration leads to clogging of thin tubes in the heat exchanger. If dirt enters the water flow sensor, the boiler will not turn on when the hot water tap is opened.

• Incorrect gas adjustment will burn the heat exchanger, venturi nozzle failure, or excessive gas consumption. Over time, the pressure in the gas pipe changes and only an annual pressure adjustment can ensure that the pressure matches the passport indicators.

Carefully treat the gas boiler, do its maintenance and prevention, and then it will serve you for a long time

That is why scheduled inspections of boiler rooms should be carried out. Maintenance is carried out by special certified organizations. In this case, the inspection includes a visual assessment of the parts and, if necessary, their repair.

Purposes of maintenance of gas boiler houses by a service company

Everyone wants a gas boiler to last for many years. But its performance depends on many factors. Poor operation provokes rapid wear of parts or their breakdown.

You can prevent the problem by regular checks, which are possible for warranty and post-warranty service.

Having a service agreement in hand, the owner can only call the organization. After receiving the application, the repair team will arrive at the site and fix the problem.

Since service centers always keep records of boilers, field team specialists arrive at the site already with the necessary set of tools and spare parts that correspond to the specific model of the gas boiler installed in the house.

But there are situations when, at the peak of the heating season, repair crews are “at break”. And the masters may not satisfy the application as quickly as we would like. Some owners in this case resort to the services of "private traders".

But it should be borne in mind that calling the first "gasman" that comes across is not the best option. And it's not even a tidy sum that the owner will have to pay. After all, no one guarantees that the master will be able to carry out repairs at a high professional level in an emergency situation.

Therefore, in order to avoid such situations and save unnecessary costs, you should not neglect the opportunity to conduct a current technical inspection before the onset of cold weather.

Video guide for cleaning the burner:

Regular maintenance of the gas boiler allows you to identify emerging problems at an early stage and not bring the situation to the point where the operation of the equipment begins to pose a threat to the health and life of households.

When choosing any technique, every homeowner prefers quality. Domestic gas equipment is no exception. Moreover, special requirements are imposed on it, because, for example, a gas boiler is designed for round-the-clock operation. And such work invariably leads to increased wear, which can to some extent prevent the service maintenance of gas boilers. But here there is another dilemma, how to understand what is included in the list of mandatory manipulations, and what will be just a pumping out of money by an employee of a service organization? In our opinion, every homeowner should understand what procedures for servicing a gas boiler a qualified craftsman must perform and in what order. In this article, we propose to figure out what manipulations, by and large useless, can increase the cost of maintenance? In other words: how to avoid "hack-work" when carrying out service maintenance of gas heating equipment?

Before signing a service contract

It is impossible to independently provide a gas boiler service - this is a fact. To do this, you need to have a special education, permission to perform such work, professional tools and devices. Naturally, a representative of a service company will meet all these requirements. But before you sign a service agreement with such an organization for a specific boiler model, you should find out what is included in the list of services. Then this list with a list of those works that are recommended by the manufacturer of heating equipment.

• Checking the performance of automation responsible for safety. This is a very crucial moment in maintenance, which involves simulating an emergency and evaluating the operation of the relevant devices in such conditions.
• Determining the correct operation, as well as the tightness of the shut-off valve, is another procedure that is interpreted as maintenance of gas boilers.
• A thorough examination of the supply gas pipeline, which is the responsibility of the owner of the house. Here, during the inspection, special attention is paid to identifying corrosion of pipes, checking the tightness of existing joints (flanged, threaded, welded). If necessary, the gas pipeline is painted.

What is a capital service?

Approximately, after a few years of full-fledged operation of the equipment, a major maintenance of the gas boiler is carried out. More specific dates are also indicated by the manufacturer. Here, priority efforts should be directed to flushing the heat exchanger. It is impossible to perform this procedure without special equipment and reagents.

Operation of a gas boiler and "force majeure"

Here, the description of the situation, which, unfortunately, often occurs in life, will be relevant. So, on the street there are severe frosts and all gas heaters are operated at the limit of their capabilities. As a result, working parts and assemblies wear out quickly. By the way, low-quality fuel, which is also often supplied to the gas system, will lead to the same result. In a word, the boiler failed at the most inopportune moment, and the repair teams during this period, as usual, are at a break and no one can say when the consumer's request is satisfied.

Equipment failure is easier to prevent than to repair later.

In order to somehow take control of the situation, you will have to call the first “gasman” who comes across, who, understanding the complexity of the situation, will take a tidy sum for services.

But whether he will perform repairs at a high professional level in an emergency situation is a big question. How to avoid such troubles? Of course, to have a service agreement with a trusted company, whose specialists will perform all the work before the onset of the cold season, with high quality and at an adequate price.

The desire of manufacturers to improve the operation of gas boilers with the latest technology necessitates highly qualified operators with sufficient knowledge in the field of program control of gas units. Our service engineers undergo scheduled training at academic sites of well-known manufacturers, in particular, Viessmann and Bosch Buderus. Further training of employees ensures timely updating of professional knowledge, which guarantees high-quality diagnostics and maintenance of the gas boiler, as well as repairs if necessary.

The knowledge and experience of the service masters must be supplemented by the presence of their own repair and technical base and tools that meet the latest technical capabilities. We can diagnose the operation of Baxi, Ferroli, Vaillant boilers, as well as any other manufacturers. Operational maintenance of your gas boiler is ensured by the presence of our own fleet of vehicles, as well as a wide range of the most popular spare parts in the warehouses of the service center.

Why is it necessary to carry out regular maintenance of the boiler?

Intending to purchase a gas boiler for an autonomous heating system or being its owner, one cannot underestimate the vital importance of operations to ensure its normal performance. News feeds of TV channels often report explosions of gas equipment, the main reason for which is improper operation and failure to detect malfunctions. The slightest malfunctions or readings of boiler automation indicators, invisible to the layman's eye and not telling him anything, can tell a lot to a professional. Minor flaws in the operation of the system, seemingly invisible, can develop into a serious problem and, as a result, lead to system failure or create a life-threatening emergency. Timely maintenance of the gas boiler reduces all of the listed critical situations to the utmost minimum.

Gas boilers are classified as fire hazardous equipment. Daily operation and scheduled maintenance of the gas boiler require compliance with relevant standards and requirements. Along with ignition, carbon monoxide (CO), which is invisible to the eye, is also dangerous. During normal operation of a gas boiler, CO is a standard product of combustion, and in small volumes escaping through the chimney, it does not harm life and health.

A dangerous situation may arise in the following cases:

• violation of the tightness of the chimney or the removal of exhaust natural gas;
• due to the appearance of soot in the chamber, a decrease in the efficiency of fuel combustion.
• misalignment of the boiler automation, and, as a result, increased / decreased gas / air content in the supplied combustible mixture.

It must be added that the occurrence of soot is a common situation for a working gas boiler, so regular maintenance of gas boilers includes cleaning the working surfaces of the burner and chamber, as well as the boiler body, if necessary.

In these or other situations, carbon monoxide can enter the boiler room. Violation of the efficient combustion of fuel leads to a significant increase in the amount of carbon monoxide emitted, which can lead to a life-threatening situation. Carbon monoxide is catastrophically toxic. A concentration of 0.1% of the volume of inhaled air can be fatal within an hour! The specialists of our service center are armed with gas analyzers that detect even the slightest leak of gas substances, including CO and CO2, methane and propane-butane. Timely diagnostics and maintenance of the gas boiler will prevent the situation from reaching an emergency state.

In addition to leak detection, cleaning of parts of the unit and adjustment of automation, our service will perform all the necessary diagnostic operations:

• exhaust gas temperature analysis;
• calculation of excess air coefficient;
• measurement of water t° at inlet/outlet;
• checking the water pressure parameter at the inlet/outlet;
• comprehensive assessment of fuel consumption;
• inspection of electrical circuits;
• other operations.

In the event of failures that the maintenance of the heating gas boiler reveals, our specialists will provide recommendations for repairs and calculate an estimate. Repair work is carried out as soon as possible.

The legal side of the issue “Maintenance of a heating gas boiler” exposes the latter as an indispensable condition for maintaining the guarantee for the boiler. In addition, it is possible to obtain permission to install, connect to a gas pipeline and start up gas equipment only by concluding an agreement with an enterprise that has certificates and licenses for this type of work. Our service has all the necessary permits for the maintenance and repair of gas boilers and related equipment.

Remember: only a professional can ensure the safe and uninterrupted operation of a gas boiler!

A gas boiler of even the simplest design works perfectly only if the components work smoothly. When the equipment is set up and debugged, the result is always perfect, the house is warm, and the equipment does not require constant attention from the residents. However, any device spends a resource of strength and reliability over time, therefore, maintenance of gas boilers is required with a complete check of the performance of the unit's components, cleaning, adjustment, etc.

Do not trust the maintenance of gas equipment to a non-specialist. The first and most important reason is the preservation of the guarantee for boiler equipment. The manufacturer agrees to comply with the warranty obligations only if the installation and maintenance of the boiler equipment is carried out by one of the service centers with the appropriate license and permission to carry out installation and operational activities.

The main advantage of a service contract in a licensed service center is a guarantee of the quality of work performed and a reduction in operating costs over the period of operation of the boiler. Service workers are trained by manufacturers and are supplied with all the necessary diagnostic and repair equipment. This means that the visits of service workers will not be delayed, and the boiler will always be in excellent condition.

Breakdowns in a gas boiler can be due to a defect that was not detected during the standard production testing procedure or due to improper operation, lack of proper care, when accumulated problems lead to a breakdown. Warranty and post-warranty service protect against both problems, and the house is provided with high-quality heating for many years.

List of works

To understand what exactly should be cleaned, checked and adjusted in the boiler, with what frequency, it is enough to look at the instructions and technical documentation, which must be attached to the boiler upon purchase. These documents provide a complete list of components and elements involved in the equipment, maintenance requirements and the frequency with which to check the status, perform service and update settings if necessary.

It is absolutely impossible to focus on this information for self-cleaning of a gas boiler. This information gives a clear idea of ​​what to expect from a service company with which to conclude a contract for the maintenance of gas equipment.

Works are conditionally divided into three groups:

1. Regular work carried out before the start of the heating season and after it, preparing the boiler for summer inactivity.
2. Capital service. Works carried out every few years and aimed at servicing elements with an initially long service life (flushing the heat exchanger, replacing seals and valves, maintenance of fans, etc.).
3. Repair in case of breakage. The procedure for actions and mandatory work in the event of an emergency, breakdown or consequences of external factors.

Seasonal maintenance schedule

Before the start of the heating season, the boiler should be brought into proper working condition, the operation of the sensors responsible for safety should be checked. Only after that the boiler is switched on for operation.

If the manufacturer is allowed to carry out routine maintenance only once a year before starting, then in addition to commissioning, 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 MOT (maintenance) is carried out after the season, then cleaning is assigned to this stage.

Required list of works:

• General inspection, removal of dirt from internal and external surfaces.
• Cleaning filters (air, gas, coarse cleaning for water).
• Cleaning and checking the burner.
• Cleaning the fire section of the combustion chamber.
• Checking the tightness of the 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.
• Boiler parameters adjustment, combustion adjustment. The process is accompanied by the analysis of off-gases. According to the composition and concentration, the master judges the accuracy of setting the boiler.
• Checking the condition of the shut-off valve.
• Checking the supply gas pipeline in the section from the main to gas equipment.
• Checking and adjusting the pressure in the expansion tank.

Overhaul

In addition to routine maintenance carried out every season, during the overhaul of a gas boiler, elements with a limited warranty period are replaced, the internal surface of the heat exchanger is cleaned, seals and valves are flagged. The main task is to replace elements that are not subject to maintenance during routine maintenance, but still have a service life.

In the event of a breakdown

In an emergency situation, when a breakdown occurs during operation, it is very important to react to the problem as soon as possible and return the boiler to working condition. Breakdowns, if they appear, are just during the heating season, for example, if the boiler operates for a long time at maximum power in the coldest period of the year. At this time, it is extremely difficult to find a specialist for a quick repair, but with a service contract, all you need is to leave a request so that the repair team arrives in a short time to fix the problem. Since the service center keeps records of boilers, a specialist already arrives at the customer with a set of necessary tools and spare parts for a specific model of a gas boiler.

How often

Without fail, routine maintenance is carried out before the heating season in order to check the performance of the boiler and its elements, if necessary, clean and adjust. The manual for many imported boilers also indicates the procedure for the conservation of equipment in the off-season to eliminate the risk of corrosion of materials and save the life of key components.

The terms of major service maintenance are set by the manufacturer, moreover, separately for each model range. Often flushing of the heat exchanger is scheduled for every fourth or fifth year of operation. However, the service center where the service contract is signed may change the terms, for example, based on the actual characteristics of the coolant or gas used.

Service organization selection

It is expensive for a boiler manufacturer to open a branded service center in each region of the country. Instead, existing maintenance firms are licensed to carry out the necessary work on equipment installed in the area of ​​responsibility of the service center. Licensing implies a certificate for a certain range of work, full access to technical documentation for the manufacturer's products, the ability to obtain new boiler components for warranty replacement.

The information itself voiced determines the choice of a service center in which it is worth concluding a contract for servicing a gas boiler:

• It should be located in the same region or city as the house with the installed boiler in order to reduce the response time of service employees.
• The center must be certified by the boiler manufacturer.
• The presence of an agreement that clearly spells out the obligations and rights of the parties, indicating all the necessary work performed by the service center in relation to a specific model of the boiler.

The list of certified service centers is available on the manufacturer's website, and any visitor can see it. This is the best option to check the appropriate approvals and certificates with your local service center.

average cost

Service centers usually provide the following options for cooperation:

• One-time visit for inspection and repair of the boiler, diagnostics.
• One-time maintenance of equipment during the first start-up or before the start of the heating season.
• Annual service, including preparation for the heating season, optionally scheduled visits for inspection and diagnostics, as well as a prepaid visit in case of a breakdown.

The cost of each type of work includes payment to the employee, payment to the service center, as well as overhead costs. If the first two aspects are approximately the same across regions and depend on the model of the boiler, its capacity and manufacturers, then overhead costs often vary significantly. It depends on the distance between the service center and the client, working conditions, the number of specialists in the center and many other factors, which introduces a large difference between the price tags of various service companies.

The table shows the average prices for various types of work, depending on the capacity of the gas heating boiler.

Basically, the table takes into account the maintenance of imported gas heating boilers by service centers with the appropriate certificate from manufacturers. Domestic boilers, both in acquisition and maintenance, are cheaper; spare parts are easier to find and replace. However, their main feature is simplicity and unpretentiousness, so you can’t expect comfortable heating or extensive functionality from them, in fact, as well as trouble-free service.
