Gas heating equipment is deservedly famous for its high performance, reliability, sufficiently high power with a relatively low consumption of “blue fuel”. But in order for the heating installation to work effectively and not create a danger to the owner and others, it is necessary to strictly follow the rules for its use and carry out. About why, how and by whom these procedures are carried out and will be discussed in this publication.
Why does a heat generator need maintenance
When purchasing a boiler for operation in closed heating systems, we all most often think exclusively about its rational use and the advantages of the chosen model. Most homeowners have been using this equipment for ten years, until suddenly, in the middle of the heating season, the boiler unit became unable to heat the room normally.
And the reason for this may be the usual corrosion of the heat exchanger: for many years without maintenance, scale has formed in the heat exchanger coil, which has led to a gradual decrease in efficiency. The power of the boiler at normal settings was not enough, which led to an increase in the temperature of the coolant and, as a result, an increase in gas consumption. A simple gas boiler during maintenance solves this problem even at the stage of scale formation. And this is not the worst scenario, what can happen to a boiler without maintenance.
Recall that a gas boiler is a set of equipment that uses gas and electricity for operation. In the event of a malfunction of the electrical system or gas pipeline, not only the property and inhabitants of the apartment in which the equipment is installed are endangered, but also the residents of the entire apartment building. Regular inspection and maintenance will allow the specialist at the initial stage to identify only emerging problems, without bringing them to the point where it poses a threat to life and health.
Gas consumption, as well as the comfort and safety of your household, depend on the quality of the heat generator.
Frequency of inspections of heating installations
Now that the need for regular maintenance of equipment is beyond doubt, the question of what this concept means should be clarified. The answer to this question is a little more complicated than it seems at first glance. The necessary procedures and the frequency of their implementation largely depend on the purpose of the boiler and what systems and devices are included in its composition. Usually, a list of mandatory “procedures” is provided by the manufacturer of a particular model of installation.
As a rule, regardless of the model, it is divided into three types of work: cleaning, checking and adjusting. Gas boiler cleaning includes the following procedures:
- Cleaning burners and all components that determine the quality and direction of the flame.
- Cleaning the fuel combustion chamber, which is covered with soot during operation.
- Cleaning of gas channels inside the boiler and fuel filters.
Works that are included in the mandatory and related to the check:
- The integrity of the device design.
- The performance of electronics.
- Ignition electrodes.
- Serviceability of automatic machines that turn off the installation in case of emergency situations.
- Gas valve pressure.
- Integrity of the gas pipeline and tightness at the junctions of the gas supply routes.
When servicing a gas boiler, all its components are regulated. This is done to set the parameters recommended by the manufacturer.
The terms of the service are clearly stated in the contract with the service company. As a rule, maintenance of gas equipment, with the performance of all of the above works, is carried out once a year. Most often — done before the start of the heating season. It is recommended to clean the heat exchanger from scale after five years from the start of operation of the boiler equipment. In some service organizations, it is customary to carry out, with a frequency of 1 time in 2 years.
Why pay more?
As can be seen from the list, there is nothing complicated in the mandatory preventive maintenance of boiler units. So why pay a service company if the equipment, according to the seller, is more than reliable, and you can do the maintenance yourself?
Advice: We strongly do not recommend experimenting and engaging in self-cleaning and tuning of gas equipment. All work must only be carried out by a well-trained specialist.
And it’s not just about knowledge: a professional will be able to identify an impending malfunction and prevent it, preventing irreparable consequences. In addition, the service center is responsible for the work performed, which is confirmed by the personal signature of the master on the certification documents.
Departing from the topic, we want to inform you that we have prepared comparative reviews on gas boilers. You can get acquainted with them in the following materials:
Self cleaning gas boiler
If you still decide to save money on maintenance, then you need to decide which work can be done on your own, and which ones can be entrusted to professionals.
We recommend that all work related to the maintenance, repair and adjustment of gas boilers be entrusted to service specialists.
Do-it-yourself flushing of a gas boiler heat exchanger is a fairly simple process that does not require specialized tools and special knowledge. There are two ways to perform these works: with or without disassembly of the system. In order to remove scale without disassembly, you need to purchase a descaling agent from the nearest household chemical store, dilute it in the correct proportion and pour it into the system. After that, you need to turn on the boiler and let it work at maximum power.
The second option is more difficult.
- Disconnect the boiler from the network.
- Perform measures to drain the coolant from the system and expansion tank.
- Remove the cover of the device with the controls located on it.
- Remove the heat exchanger. In some models, this will require disassembly of the combustion chamber.
- Rinse the heat exchanger with a solution of citric acid or a specialized descaling agent.
- Follow the reverse procedures for installing, assembling the boiler, as well as filling the system with coolant.
It should be noted that for high-quality flushing of the heat exchanger in service centers, pumping stations are used, which will perform this procedure faster and better. It is enough for you to remove soot from the surface of the heat exchanger every year.
There are a lot of “experienced” tips on the Internet about self-cleaning the gas valve. Before following the instructions, understand its purpose and design.
The purpose of the gas valve is to supply gas to the burner depending on the set power. In addition, the gas valve is responsible for stopping the gas supply when any of the safety sensors are triggered. Cleaning this valve consists in cleaning the gas filter, which is installed inside the gas supply fitting. Despite the fact that this procedure is not particularly difficult, it is still better to entrust it to professionals.
