Technical maintenance of gas boilers: current service and major repair

Technical maintenance of gas boilers: current service and major repair

Technical maintenance of gas boilers - guarantee of stable, correct and safe operation of the equipment. Regular inspection and check of operability of the heat unit allow to reduce risk of output of the boiler out of operation, and with fault - in due time to find and eliminate it.

Modern gas boilers have economic fuel usage, high utilization properties and reliability. Therefore the increasing number of consumers chooses boilers on gas for heating of owner-occupied dwellings and non-residential premises. Quite often owners of heating system forget that without due service efficiency, safety and profitability of boiler decreases many times.

Technical maintenance of gas boiler allows:

  • to exclude risk of breakage in heating season;
  • it is essential to prolong unit life cycle;
  • to avoid financial costs of repair or replacement;
  • to ensure its serviceable and continuous functioning.

As the gas boiler is the equipment which for work uses both gas, and electricity, in time to reveal damage of elements or wear of parts of heating system very important to exclude risk of leak of gas, ignition or fire. Observance of instructions for use of the equipment on gas and regular technical maintenance will help to avoid expensive major repair or replacement of boiler in the future. Besides, service allows to exclude risk of operation of faulty heating system, helping to provide the dwelling with high-quality heating for all term service of boiler.

What requires technical maintenance of boiler

Let's consider on example as without technical maintenance the boiler begins to consume more gas and over the years warms the room worse and worse. It is known that the heat exchanger of the gas heatgenerator is subject to corrosion and scaling. If pipes in due time do not wash out and do not clean, then the scum and pollution become obstacle for the required heat exchange.

Power of boiler decreases, and together with it heat carrier temperature increases. So, the consumption of gas increases, and the boiler unit stops being effective and economic. It is obvious that regular service will help to exclude similar problems with boiler. Check of operability of boiler is necessary also for the reason that over time knots and parts of heating system wear out and demand replacement. Standard check by the licensed service center includes visual examination of parts and parts of system regarding damages and wear, and if necessary experts carry out adjustment or repair.

Basic reasons of breakage of gas boiler

Breakage of boiler on gas occurs for such reasons as:

  • defects which were found on production, during testing;
  • misuse and lack of appropriate care;
  • lack of the required technical maintenance.

If to ignore signs of decrease in efficiency of boiler and not to carry out inspection, then users risk to be left without heating in heating season because of its breakage. On the contrary, timely service and repair of the gas device is condition of safe operation of the equipment and also opportunity to reduce heatlosses, to normalize boiler efficiency, to increase overall performance of the unit and to solve other problems.

Types of works on technical maintenance of boilers

Service and check of heat units are carried out by operators-servicemen from the signature service organizations. To keep guarantee for the boiler equipment from manufacturer and to lower maintenance cost for operating time of gas boiler, it is impossible to trust installation, repair and replacement of boiler and its elements of the third-party unspecialized company. It is not necessary to choose doubtful firms without license and permission to performance of assembly and operational actions even if they promise to execute inspection of the boiler cheap.

Works on technical maintenance divide into 3 views:

  • Regular works. According to regulations carry out every season prior to operation of the boiler and after it, for preparation for summer inaction to exclude risk of corrosion and to save resource of knots and components. Works include: survey and cleaning of basic elements of the unit.
  • Capital service. Deep check which is carried out according to the schedule, time in 3-5 years. Enters work: washing of the heat exchanger, replacement of valves, glands, check of fans and other elements.
  • Running repair in case of unexpected breakage. The boiler working long time at the maximum power can fail for various reasons. Not to be left without heating and to fix problem, it is necessary to leave the application in customer service with which the contract for service is signed.

Only the specialized service organization can provide guarantee for the performed works, order new parts for guarantee replacement as has all necessary resources to keep boiler in excellent condition. As a rule, personnel and master servicemen have qualification and experience, and, above all - take course at the producer of gas devices and have the necessary repair and diagnostic equipment for model of gas boiler of the customer. So, on user request or according to the plan of checks, specialists of service come, check condition of boiler, carry out service and update settings of the unit if necessary.

What enters capital service of the gas equipment?

Capital service of the gas unit includes works on cleaning of the furnace camera, torch and other elements. Connections for exception of risk of leak of gas, pressure in heating tanks, torch operation parameters are checked. Cleaning of mud collectors and filters, expulsion of sensors of air is carried out, replacement of faulty parts is made. The master serviceman estimates condition of smoke and ventilating ducts and also tightness of knots.

So, standard capital service of the gas equipment includes check of working capacity, replacement and repair of such elements as:

  • Works on expulsion of the sensor of air and presence of flame, cleaning of electrodes of the pilot light and washers, removal of deposit from flue, washing and replacement of filters.
  • system of automatic equipment. Check of the knots which are responsible for fuel usage, operating mode and safety of operation of the unit. Competent control of the automatic mode helps to reduce gas consumption to 25%.
  • gas channels. Work on cleaning of pipes on which the energy carrier moves. Check of the electromagnetic valve blocking gas supply on tightness.
  • check of goodness of all connections of supply of gas. It is necessary to evaluate elements on availability of corrosion and tightness.
  • combustion chamber. Cleaning of the parts adjoining to torch flame.

It is obvious that after-sales service of the gas equipment helps to prevent serious breakages. Terms of checks and capital service are established by the producer. As a rule, after end of warranty period of operation of the boiler, before the first check by the expert there have to pass 6 months.

Frequency of checks of heat units 

In spite of the fact that producers of the gas equipment release boilers with the increased characteristics of durability and wear resistance, maintenance inspections cannot be neglected. Requirements to service and frequency of checks of heat units is specified in technical documentation on boiler. So, terms of checks and survey are specified by producers in the application guide and in the contract between the user and the representative of customer service. For each model range of the gas equipment establish the terms.

Surveys as part of service need to be carried out every season. For preparation for heating season, before start the boiler is brought into appropriate working look, clean basic elements and check sensors which are responsible for safe operation. It should be noted that the service company can change terms of checks taking into account characteristics and the actual features of gas or the heat carrier which is used in boiler. It is obvious that service of boiler is obligatory prevention of emergence of faulty operation of the equipment.
