Pneumatic heating test
Pneumatic heating test
In some cases, it is impossible to meet the basic conditions for carrying out a hydraulic test of a heating system. A similar situation may arise after repair work is carried out in winter, when the ambient temperature is below +5°C. Then you should draw up a pneumatic test report for the heating system.
Its essence is to create a pressure of 100 kPa in the heating lines. Moreover, within 10 minutes the level of its decrease should not exceed 10 kPa. To check this, you should use pressure gauges with an accuracy class of 2.5 and a division value of no more than 5 kPa. All characteristics of the equipment may be present in the pneumatic test report of the heating system.
It is not recommended to carry out such checks for polymer pipelines. However, the standards allow testing of air heating systems made of polypropylene or metal-plastic in the following cases:
- Technical conditions do not allow filling with liquid. Most often this is due to the use of antifreeze;
- Ambient temperature below 0;
- Temporarily there is no coolant in the required volume.
The main problem when testing a system by air is finding places where tightness is lost. If a sharp decrease in pressure was noticed during the procedure, it is recommended to perform a zonal check of the areas. This is the only way to determine the location of a possible leak. Therefore, they prefer the hydraulic method as it is more convenient.
Upon completion, a pneumatic test report of the heating system is drawn up, in which the results are entered.
To correctly draw up the act, it is recommended to fill out the forms in the accepted form. They can be obtained at the office of the management company or on its website.
Why do batteries get cold?
There are two heating schemes - one-pipe and two-pipe.
Two-pipe heating system.
A special feature is the presence of two pipeline branches (supply and return). To operate such a scheme, two pipelines are required - a supply pipeline and a return pipeline. Both pipelines are connected to the heating radiator. The hot coolant enters the battery through the supply pipe, and the cooled water returns to the heating system through the return pipe.
Unlike a single-pipe circuit, heat is supplied to all heating radiators at an equal temperature, without losing the characteristics of the coolant on the last radiators along the line.
Single pipe heating system.
Feature - the temperature on radiators located closer to the supply pipeline is higher than on radiators located at the end of the heating riser. However, this effect is offset by the number of radiator sections. Radiators that are closer to the supply have fewer sections. Radiators that are closer to the return line have more sections.
In a single-pipe scheme, the coolant is supplied through a heating riser located vertically between two heat supply pipelines (beds) (supply and return). Pipeline beds are usually found in the attic and basement of a building. Heating radiators are connected in series to the riser pipe.
The coolant flowing from the supply pipeline to the return pipeline gradually loses its original operating temperature.
In houses of early construction, this heating scheme is usually used. Previously, builders were very happy with this, because... the scheme uses only one pipeline, installation of the riser is easy to perform, savings on material consumption (there are no additional fittings, pipes, benches, jumpers and return risers) and ease of maintenance.
A feature of a single-pipe system in apartment buildings is the presence of a bypass. After dismantling the bypass, the coolant circulates only through the heating radiator. If the shut-off valve (tap) on the battery is closed, the circulation of the coolant will stop and the entire heating riser will stop. - The heating radiators of the remaining residents will cool down

How to understand that balancing is needed
Any system, or rather its components, needs a fixed amount of media . For example, radiators in the bedroom and kitchen receive different volumes of hot water. This is primarily due to the settings and general requirements for the system. When the hydraulic balance is disturbed , the boiler gives off almost all the heat to the nearest battery, the rest remain cold. So it turns out that one room is hot and the other is cool.
It should also be taken into account that in such conditions the heat generator operates in enhanced mode. Increased loads negatively affect the components. This can lead to a breakdown, which will cost you thousands of rubles to fix. Problems can be avoided using hydraulic separators and balancing manifolds . It is their purchase that all owners of country houses, cottages and other premises with autonomous multi-circuit heating should think about.

Guidelines
A sample of filling out the act is available at the supplying organization. First, the date of testing is indicated. You must enter the name of the object and its address. Here you need to start from the passport of the building. After this, the persons who took part in the work are listed.
The hydraulic test report should be stored carefully
Most of the inaccuracies arise when filling out the column that lists the physical parameters of the heating or cooling system tests performed.
The next point is the area or place where the tests were carried out. Here you need to remember that the full name of the object is indicated.
The process of further filling out the pipeline survey report is as follows:
- Test and working pressure size;
- Time of its fixation;
- Pressure gauge indicators;
- The result of the visual inspection;
- List of repairs carried out or recommended;
- Conclusion about the performance of the system under study;
- Signatures of responsible persons.
A certificate of suitability of the system for further operation is drawn up by the supplying organization or persons who have received the appropriate approval. The regulations for all events are prescribed in SNiP. Strict implementation of all recommendations is a guarantee that the document drawn up will have legal force. Each stage of testing is carefully recorded. All information collected is used to compile the final report.
