Cleaning the heat exchanger of a double-circuit boiler by one's own hands: clean the gas boiler from soot, the burner from scale

Cleaning of a double-circuit boiler must be carried out annually before the start of the heating season, which will increase the efficiency of its operation. . If desired, it is possible to clean the heat exchanger of a double-circuit boiler without using the services of specialists. This procedure does not take much time, besides it will not be necessary to spend extra money. The main thing is to follow certain rules and know the operating principle of the gas boiler. Having spent only 2-3 hours of time, it is possible to clean the equipment qualitatively from pollution.

Why cleaning the boilers and heat exchangers

The gas boiler heats the water when it burns gas. The heat exchanger of the structure is a copper or steel bent pipe. When the gas is converted into energy, the heat exchanger also heats up, transmitting heat to the heating system. Heating is carried out, thanks to special plates, they also help to raise the temperature and direct to one of the contours of the two-circuit system.

Today there are several basic ways to clean or flush the boiler heat exchanger, but the most important are the chemical and mechanical methods

A heat exchanger is made of the following materials:

• Copper;
• Stainless steel;
• Copper alloys.

This is because copper and its derivatives conduct heat well.

These plates are usually covered with sediments due to contact with water, so they must be cleaned every two years before switching on the heating for winter time.

If the water is sufficiently hard, the heat exchanger must be descaled 1 time in 2 years. You can do it yourself, having prepared the necessary tools in advance.

Ways of cleaning: how to clean the gas boiler

In order to avoid overheating of equipment parts, breakage and increase of fuel costs, periodic cleaning and cleaning of the heat exchanger and other elements is required.

When selecting the boiler cleaning method, they usually focus on their own capabilities and knowledge

The heat exchanger can be cleaned in several ways:

• Manual cleaning, involving removal of the coil, it can be done mechanically or it will have to be washed with a special compound, Which dissolves the salt;
• Acidic liquid cleaning with booster;
• Variant of hydrodynamic washing with application of increased pressure is possible.

Manual cleaning is carried out using a stiff brush and a vacuum cleaner. For a double-circuit boiler, use antiseptic liquid from the lime coating. First, the coil is removed, and after the procedure it returns to its place. Particular attention should be paid to leak testing.

It is also possible to clean the pipe with a booster. For this purpose, a special solution is passed through it, which is capable of removing even the deposits of iron compounds. At the end, the acid is neutralized by another liquid that is pumped through the pipes.

The hydrodynamic method allows efficient destruction of plaque and deposits by increasing the pressure and applying abrasive substances pumped into the coil.

Procedure: How to clean the boiler of scale, carbon and soot

If it is decided to perform the procedure for cleaning the structure with your own hands, before starting work at home, you must turn off the electricity, close the gas, close all the valves of the heating system and boiler.

In order to ensure high-quality cleaning of gas equipment from soot and carbon deposits, it is necessary first of all to acquire the necessary tool kit

All operations should be performed carefully, disassembly and assembly requires special care:

• The boiler cover is removed;
• Next, remove the gas burner, remove any deposits from the electrodes in the form of carbon deposits, rinse the surface with water and detergent, rinse;
• Brush with soft hair to clean the injector, nozzles;
• Then the fan is removed, and its blades are cleaned;
• The wall of the combustion chamber of the AGB is removed;
• The heat exchanger should be cleaned with soot, rinsed with scale with citric acid or a special formulation;
• Having dismantled the coil, it is necessary to clean the bottom of the boiler;
• The filter for cold water is then cleaned, purged and rinsed with clean water;
• All items are returned to their original positions;
• The tightness of the AOGV is checked.

After completing all the necessary procedures, you can open the gas valve and turn on electricity.

Practical advice: how to clean the gas burner of the gas boiler

When the boiler is running for a long time, the burner gradually generates soiling in the form of a deposit. Accumulating in large quantities, it can cause malfunctions in the operation of equipment. Therefore, you must periodically remove it.

Independent cleaning of gas boilers is possible only in that part of the equipment that does not use the gas supply

For mechanical cleaning with small accumulations of dirt you will need:

• Brush;
• Ershik;
• Thin needle.

The flue must be cleaned without fail. The surface of the nozzles is cleaned with brushes or a brush. A needle is used for the holes. In no case should the hole be widened, since the combustion process can be disturbed.

If there is a lot of carbon, you can use acidic solvents.

Cleaning the Aton gas boiler with your own hands( video)

Any gas boiler, even if manufactured by such well-known companies as Aton or Vylant, requires respect and concern. Timely prevention, washing and cleansing from various types of pollution is a guarantee of uninterrupted and long-term operation of this type of equipment. However, for independent work, it is important not to forget about the correct assembly and safety rules.
