What determines the life of a gas boiler in a private house: what affects + tips for extending life

Main malfunctions and methods of elimination

The sensor system constantly monitors the status of all boiler components, in the event of any failures, signaling to the control board. A specific code appears on the display, indicating a particular malfunction.

Main error codes:

• E01. There is no flame. There may be a lack of gas supply, a failure of the ignition system, or a sensor failure.
• E02. Overheating of the heat exchanger. The reason is a layer of scale or a decrease in the cross-section of pipelines.
• E03. Failure or failure of the fan. Replace device.
• E05. Failure or short circuit of the OB temperature sensor.
• E06. Failure or short circuit of the DHW sensor.
• E10. Low pressure RH. There may be a leak in the boiler itself or somewhere in the heating circuit.
• E25-26. Circulation pump failure or sensor failure.
• E35. Parasitic flame. The appearance of water drops on the board, a breakdown of the sensor power supply to the board.
• E96. The voltage in the network has dropped.

The full list of codes is much wider, but it makes no sense to give it in its entirety. When a particular code appears, press the "R" button and hold it for 2-3 seconds until the error is reset. If it appears again, you should urgently call the master.

General operating instructions

Before starting to operate a gas boiler, it is necessary to connect it to the gas network, heating pipes, cold and hot water supply (if the unit is double-circuit and is also intended for preparing hot water), electrical network, which must meet the technical characteristics of the machine. Connection to gas is carried out only by certified employees of the gas service. Water is connected and the first start-up of the boiler is carried out by representatives of a specialized organization for servicing heating systems. When connecting, strictly adhere to the requirements of the warranty card and operating instructions, otherwise the warranty will be void.

The gas boiler may only be used for the purposes for which it was intended.

Table of the required volume of the boiler room depending on the power of the boiler.

The manufacturer is not responsible for improper operation of the boiler, violation of the rules of operation and for damages associated with this. This will also void the warranty.

Installation, service and other work must be carried out in full compliance with the regulatory and technical documentation and the user manual. Only original spare parts must be used for this.

If a malfunction and / or breakdown of the unit is detected, immediately turn off the gas supply with a tap and call a qualified specialist. It is strictly forbidden to carry out any work on the gas boiler yourself.

When performing any work on or near air ducts and chimneys, it is necessary to turn off the device and turn off the gas. After completion of work, before turning on the boiler, check the functionality of the air ducts and chimneys.

When turning off the gas boiler for a long time

• close the gas valve;
• when the boiler automation is powered from the mains and there is an electric water pump, disconnect them from the line;
• turn off the taps of the cold and hot water supply system, heating system;
• if the heating system is filled with water and the ambient temperature is expected to fall below 0°C, the heating system must be drained of water;
• the final shutdown of the unit should be entrusted to a specialist.

When cleaning the boiler, turn it off. It is allowed to clean the device with damp cloth rags with a mild detergent and soapy water. Do not use aggressive chemicals for cleaning, including detergents, insecticides, and other toxic substances.

It is strictly forbidden to use and store flammable substances in the same room with a gas unit.

Maintenance nuances

Maintenance of gas boilers is carried out to extend the life of the equipment. The schedule and frequency of work are determined by the manufacturer and should not contradict state regulatory requirements for the operation of gas equipment. Main maintenance activities:

1. Burner device - cleaning the retaining washer, igniter electrodes, flame sensor.
2. Purging the sensor by air pressure to create a gas-air mixture.
3. Flushing or replacement of cleaning filters on the gas line.
4. Cleaning of all parts of the boiler exposed to open fire.
5. Cleaning of gas channels and gas ducts.
6. Chimney cleaning.
7. Checking and repairing electrical circuits and the boiler operating panel.
8. Adjustment of all units of the unit.

Maintenance of the boiler unit should begin with a thorough inspection of the units of the thermal circuit and a description of the defects of the detected violations. It is completed after all faults have been eliminated. Replacing defective or defective parts and performing adjustment work of the entire heating system.

As is obvious, the maintenance work package covers all the main elements of the unit, and its implementation will require not only experience and knowledge, but also instruments and devices. For most users of boiler equipment, these conditions are not feasible, so it is better to contact the service department for outdoor gas boilers, which are available in all regional centers, for example, in Moscow. For people living in the suburbs, it is enough to make an application by phone or on the website, the specialists themselves will come to the house to carry out the work.

Installation rules

Placement of thermal units according to the value of thermal power and requirements for premises:

1. An analysis of the requirements for placement depending on the thermal power revealed that thermal units can be placed:
   • in the kitchen (with power up to 0.060 MW);
   • in a separate room: any floor (with power up to 0.150 MW); not higher than the first floor or in a separate attached room (with a capacity of up to 0.350 MW);
2. The area of ​​the boiler equipment to be installed is not less than 6 square meters, the height is not less than 2.5 meters.
3. The fire resistance limit of enclosing structures is 0.75 hours. The requirement does not apply to the kitchen.
4. The size of window openings for natural lighting of the room is 0.03 square meters. for every cubic meter.
5. The room located in the house must have a separate exit to the local area.

Installation of gas pipelines

The requirements for the installation of gas pipelines are taken into account during the design and implemented during the construction and installation works. It is not recommended to independently carry out the installation of gas pipelines, since these works, according to the requirements of regulatory documents, are performed by specialized organizations.

The GDO inspector, when checking the readiness of the gas pipeline, will identify this violation, impose a fine, and specialists will have to be invited.

Installation of boiler equipment

Installation of the boiler is something that really can be done on your own.

If the boiler is already installed, this reduces the amount of construction and installation works, and, consequently, reduces the cost of their implementation.

Equipment-specific settings are set out in the operating instructions. However, you need to know the regulations for the placement and installation of boilers. This may affect the choice of design of a heat generator when buying, and possibly determine its place on the territory of the house.

Installation of floor heat generators

1. The heat generator is installed as far as possible from sources of open fire.
2. The distance from the protruding parts of the fuel generator or burner to the wall is 1 meter, at least.
3. A free approach is provided.
4. The distance from walls made of combustible materials and covered with non-combustible or low-combustible materials is at least 3 centimeters.
5. The floor covering directly under the heat generator must be made of non-combustible materials and be, for example, concrete blocks covered with a sheet of metal.
6. The protrusion of the flooring beyond the base of the heat generator is 10 centimeters.

Installation of wall-mounted heat generators:

1. The distance from the wall intended for installation, made of combustible material, and covered with non-combustible or slightly combustible material is at least 3 centimeters.
2. The distance from the upper plane of the heat generator to the ceiling and from the side surfaces to the nearest walls is 1 meter at least.
3. It is forbidden to place the heat generator above the sink or gas stove.

Do I need a new project when replacing a gas boiler

The project specifies the model, type and power of the heating unit. In addition, each boiler has its own serial number, indicated in the data sheet and included in the project documentation. Therefore, when replacing, you will need to make a new project with new data.

You need to go through the following steps again:

• Obtain specifications for the replacement of a gas boiler. At this stage, the gas distribution company can change the capacity of the unit based on the actual living area of ​​the house.
• Make a new project.
• Obtain approval by submitting a gas distribution project, specifications, and the results of checking the chimney channel.
• Replace the old unit with a new one.

When replacing an old gas boiler with a new one, the following documents are needed:

• The passport.
• Documents of the owner of the dwelling.
• Technical passport for gas equipment.
• Specifications.

Standard prices for the replacement of already installed gas equipment are 1000-1500 rubles, depending on the region.

Mounting method

There is a direct relationship between service life and type of gas heat generator, which are floor and wall-mounted.

Outdoor, more monumental and powerful. Their construction uses materials that are resistant to high pressure and temperature.

For heat exchangers of floor boilers, steel and cast iron are used, which have high strength characteristics.

Mounted (wall-mounted) - lighter and more compact. The small dimensions and weight of the device are due to the material of the heat exchanger.

As a rule, wall-mounted boilers use a copper heat exchanger, which, due to its high heat transfer, has smaller dimensions and weight. But copper is fragile and subject to corrosion, which leads to a fairly quick failure of the heat exchanger, especially with irregular maintenance.

You should be aware that steel heat exchangers, like copper ones, are susceptible to corrosion. That is why most of the leading manufacturers in this market segment use high-quality stainless steel for the production of steel heat exchangers. Cast iron coils are not susceptible to corrosion manifestations, but they are very “painful” to pressure drops. Both factors affect the life of the boiler.

How to choose a gas boiler

According to the installation method and the basic principles of operation, heating gas boilers are divided into groups:

• Mounted;
• floor;
• Condensing.

Each type has its own advantages and, as usual, disadvantages. To choose a thing that is really necessary in the household, you need to understand what are the differences between different models.

The mounted (wall-mounted) boiler is characterized by the following advantages:

• Profitability;
• Ease of use;
• Compactness;
• Ease of installation.

If, in addition, we consider double-circuit gas heating boilers, then the advantages of the models include not only heating the house, but also the production of a sufficient volume of hot water for everyday consumption. The design of the device provides all the elements for the excellent operation of a home boiler room. This is a circulation pump, and an expansion tank, as well as a safety valve, the necessary elements of a security system, etc.

The wall-mounted gas boiler is compact and fits perfectly into any interior.

When choosing a gas boiler, it is worth considering such options, the operation of which will be the most convenient and productive for the user.

For mounted models in this aspect, you should pay attention to the following characteristics:

• The presence of forced removal of combustion products;
• Possibility to use different power modes for summer and winter seasons;
• Minimal dependence on power supply, which allows the equipment to work even in the absence of electricity;
• Structural features of the burners, "adjusting" to the change in gas pressure.

Important! If you give preference to a gas boiler that operates strictly from the mains, then during power outages you can be left not only without light, but also without heat and hot water.
The floor heating gas boiler is valued for its reliability, relative cheapness and ease of operation. Its design does not change over time, as well as the materials used in production. Most often you can find gas boilers with heat exchangers made of steel or cast iron.

Floor standing gas boiler - a traditional solution, characterized by reliability and excellent quality

The main division in this group is carried out according to the types of burners, which are:

• atmospheric;
• Supercharged (replaceable).

The first option is an inseparable part of the boiler design and is taken into account when forming the cost of the product. Atmospheric burners are easy to operate and have a quieter sound during operation. But at the same time, professionals recommend purchasing gas boilers with pressurized burners. There are several reasons:

• Higher efficiency in work;
• Possibility of operation of the boiler on gas or liquid fuel;
• Better functionality;
• High power ratings - up to several thousand kW.

For information! The power of gas boilers with atmospheric burners rarely exceeds 80 kW.
Also, floor-standing boilers are practically independent of electricity, that is, they are autonomous in operation. Previously, outdoor equipment was offered only as non-volatile. Now there are many imported models that are designed to European standards.

Therefore, it is extremely important to know what reviews and recommendations are on gas boilers.A thorough study of the information will help not to make a mistake in the choice. A significant disadvantage for floor boilers is the need to equip a chimney

This fact complicates the installation of equipment and increases the requirements for the quality of its installation.

The condensing boiler has an efficiency of up to 120%

Condensing gas boilers are a separate group, as they differ in unique operating parameters. According to the installation method, the equipment can be both floor-mounted and mounted. However, the design of the boiler allows you to achieve efficiency from it that exceeds the 100% threshold. This makes the condensing unit the most economical of all models on the market.

Regulatory documentation for replacement

The master will not be able to dismantle if there are no relevant documents

Boilers AOGV and AGV can only be changed with the consent of the relevant authorities, since the life of people depends on the correct performance of the work. For this reason, only specialists should do this.

It is unacceptable to make an unauthorized replacement, but dismantling can be done with your own hands, these requirements are indicated in clause 5.5.2 by Decree No. 170 of the Gosstroy of Russia.

Previously, the owner of the property needs to draw up the relevant documents:

1. Certificate for the boiler, which must meet Russian requirements for safe operation.
2. The act of checking the systems of intra-house smoke ventilation.
3. Technical passport and factory operating instructions for the unit.
4. Reconstruction project for the gas boiler installation system.
5. For a double-circuit model, a sanitary and hygienic conclusion on the DHW system will be required.
6. After all the listed materials have been prepared, you can transfer them to the appropriate department of the city gas company to obtain a permit for the operation of new gas equipment.

Tips and Tricks for Successful Hardware Replacement

In order to simplify the process of obtaining permits, it is recommended to invite a specialized company to install new equipment that replaces units in private homes and has the right to turnkey production with the execution of all necessary documents and further after-sales service.

• replacement of a gas boiler with an increase in power;
• replacement of the heating system, for example, "warm floor";
• replacement of types of heating devices with more economical ones;
• change the model of circulation pumps;
• turn on the two-circuit system for heating and hot water;
• automation of heat and power processes;
• installation of a battery tank to reduce overall energy consumption;
• assemble a scheme for combined heat generation with the transition to multi-part tariffs for electricity.

Note! When making decisions to install individual heating, the user should initially plan to replace the boiler at least 20 years from now, although given the speed of innovation in this industry, the emergence of new green technologies for domestic heating on the market will most likely have to be done much earlier.

Factors affecting gas consumption

There are three factors that affect gas consumption in your home:

Heat loss.Each house has its own value of heat loss and in each unit of time the heat loss of the house is different. They are often calculated based on the lowest possible temperature values ​​​​in your area. It's pretty easy to calculate them. The Internet is full of ready-made calculators. A lot of factors affect the losses in the house: the thickness and materials of the walls, insulation, windows, doors, ceilings. In other words, absolutely everything affects losses.

Heat losses are measured in kilowatts, as is the power of the boiler. As you already understood, based on the magnitude of the losses, the boiler power is selected.

• The heating system itself. Whatever one may say, if your heating system is not thought out, not balanced, then an overrun will also be observed. Not as much as with heat loss, but still there. In this case, usually in some room there will be overheating, in some kind of underheating.
• The boiler itself. Depending on the type of boiler, the gas consumption also depends. Floor boilers consume more, wall-mounted ones consume less.

What to do if the service life of the gas pipeline has expired?

In the event of the expiration of their service life, they must be repaired, which provides for the complete or partial replacement of elements.

If the competent persons have already carried out an inspection and come to the conclusion that a replacement is necessary, the consumer does not need to do anything. Repair work must be carried out by employees of GorGaz or other similar services serving the facility.

Each consumer must be familiar with the rules for operating the gas pipeline, and also be able to shut off the gas supply to the apartment if necessary.

For a complete replacement of the gas pipeline, a mobile team is sent to the site, which removes the failed sections of the main passage to the common house complex of pipes, and then looks at the situation.

Partial replacement of pipes in a multi-storey building is carried out by cutting off old sections and placing new ones by welding.

Such events are carried out strictly according to safety rules:

1. The access of gas to the pipes is blocked.
2. The site to be replaced will be completely vented of the gas in accordance with the safe handling of hazardous facilities.
3. Cut off the old section.
4. By welding, a new element is mounted in its place.
5. Checking the integrity and tightness of the site.
6. Starting the gas flow through the pipe after purging them.

Repair of gas equipment cannot be done independently. This is a complex and dangerous process that can only be carried out by employees of the gas industry with the necessary equipment.

Moreover, the fact that such work was carried out, as well as the date of their implementation, it is necessary to enter information into the data sheet, in which all actions carried out with the system are noted. This is necessary in order to subsequently be able to determine the service life of the new gas pipeline.

To extend the life of the internal gas pipeline, operate it in accordance with the rules. For example, do not kink the hose that supplies gas from the system to the stove

If the consumer suspects that the pipes have become unusable, he can make an application to the relevant utilities and wait for the arrival of their employees, but in no case should you check your version without their presence.
