How to steal air from a heating system

Surely many people faced such a problem when, touching the heating radiator, they understood that its upper part is hot and the lower one was absolutely cold. This is the first sign that in the heating radiators there is air that does not allow the coolant to enter the lower part of the radiator, thereby heating it.

Therefore, answering the question of what the heating system affects, we can safely say what is influenced, primarily on the efficiency of the entire heating system. With one heated half, the heating radiator will not be able to give as much heat to the premises as with its normal functioning.

Publishing the heating system also affects the performance of the heating boiler. The pump of the heating boiler is much easier to pump the coolant without air in it. Often the reasons for stopping the circulation pump in the heating boiler, there is also an excess of air in the heating system.

These are not all problems associated with the bullying of the heating system, since there are much more of them. Therefore, it is obvious that how, having heard that in the heating radiators, something gurgles, and this is nothing more than air, you should immediately start fainting the heating system.

In fact, the heating system is not very difficult. Depending on what kind of heating radiators are in the house, the heating system will turn out in several ways.

How to drive air out of old cast.Iron batteries

If old cast.Iron heating batteries are installed in the house, then in order to steal air from the heating system, there should be a small ball valve on the upper part of the battery. Having opened the crane, you need to wait until all the air comes off the heating device and one water does not go. If there is no crane, then with the help of plumbing “crabs” you can unscrew the nut or fainter, thereby frightening the air from the cast.Iron battery.

How to expel air from aluminum heating radiators

It is much easier to the situation if you need to steal air from the heating system if new aluminum or steel panel radiators are installed in the house or apartment. In such heating devices, on top of one of the side sides, there must be a crane of Maevsky.

In order to break the radiator using the Maevsky crane, a special Maevsky key is used, which is inserted into the crane, and then turns counterclockwise at several revolutions. After the air has completely left the air from the heating radiator, you can tighten Maevsky’s crane back on the hand.

It happens that a key, Maevsky is not possible to find, then you can use it in order to steal the air from the radiator with an ordinary flat screwdriver. But only a prerequisite in this case. The screwdriver should have a subtle and durable sting.

Otherwise, the screwdriver can simply be tanned. The fact is that in the process of heating the radiator, the maevsky crane can simply “boil” and stick. Therefore, unscrewing it with a screwdriver is often problematic.

As you can see, the bullying of the heating system is not such a big problem as it seems at first glance. Well, in order to steal air from the heating system, it will take no more than half an hour, well, or an hour maximum.

Pressure setting

To raise pressure, a fuel tap is used, and in order to lower the pressure, the descent valve.

The range of 0.7-1 MBAR is considered the best value. Typically, Baxi boilers independently support the right value, but sometimes failures arise. If there is a constant fall that does not disappear after the system is fed, then somewhere there is a leakage.

This may mean either a leak of pipelines or radiators, a warm floor system or other external elements.

Often the problem arises due to a malfunction of the descent valve. An abnormal increase in pressure may be due to a malfunction or open tap of recharge or damage to the membrane of the expansion tank.

How to turn it on

Connecting the boiler to the power supply network is carried out only after the connection of all pipelines supplying water, OV and gas.

It is necessary to carefully check the correctness of the connections, pay special attention to the gas pipeline.

Check the absence of leaks using a soap solution, if the deficiencies detect immediately fix them on your own or with the involvement of specialists of the corresponding profile. After that, the boiler can be filled with water, opening the fuel tap.

The pressure should be from 0.7 to 1 MBAR. When the pressure reaches the desired value, you can start the boiler.

Manipulations before installation work

The presented boiler is intended for the highest possible water heating to the optimum temperature of the boiling point at atmospheric pressure. The Baxi Main Four 240 F device must be connected to heating installations and distribution networks of hot household water. Before purchasing, each person must carefully read the instructions, as well as determine the compatibility of all the declared characteristics and power.

BAXI Main Four 240 F Boiler Before connecting you need:

  • Wash thoroughly, and clean the pipelines to remove possible impurities;
  • Check the suitability of the boiler to work on the supplied gas. This can be done thanks to the inscription on the factory packaging or on the plate, which is attached to the passport;
  • Determine the optimal indicators of chimney traction. The boiler should not have narrowing or other graduation pipes from other devices;
  • Equip the proper type of chimney so that there are no narrowing and final pipes are connected to other devices;
  • The boiler joins at an existing chimney. The owner needs to carefully check its cleanliness, because during the design of the design, slags can be separated from the walls and become an obstacle for the free release of outgoing gas.

Temperature adjustment

To add or reduce the temperature of the oat and left of the display, there are buttons “” and “-” (there are a special regulator on older models, the temperature rises clockwise and vice versa).

If an indoor thermostat is used, adjustment is made from it, and only the limit values ​​are installed on the boiler.

When setting temperature, the parameters should not be changed with jumps to large sizes. It is necessary to change the regime smoothly, give some time to overcome the inertia of the system. This will mitigate the transition to another mode and extend the life of the boiler.

Baxi boilers

Consider the basic device of the Baxi boiler. The principal scheme is printed in the instruction manual for each specific model, but the main nodes will be the same.

The chimney is located at the top. Immediately under it is installed a fan with a vendori tube and an exhaust cap for the output of combustion products. Below is the primary heat exchanger, having the appearance of a radiator and a coil, a little to the left is a safety thermostat and a NTC heating temperature sensor.

The center is located in the center, inside which there is a burner and electrodes of ignition and ionization of the flame. A gas ramp with nozzles is connected to the modulation burner, which receives gas from a gas valve.

A pipe connected to an expansion tank and circulation pump comes out of the right side from the heat exchanger. The pump is equipped with an automatic air sophistication valve. It ends below the drain of the coolant from the apparatus and by the pressure gauge, water from the heating system of the house enters it.

A pipe is lowered on the left side, on which a hydraulic pressure relay and a safety valve are installed at the end. Water comes out of it into the heating system. These pipes are connected by automatic bypass.

In dual.Circuit models, a secondary plate heat exchanger, priority sensor of the hot water and a three.Stage valve are additionally installed. Series of models of Baxi Moon 3 Combi and Nulova 3 are equipped with an indirect sizes of a small volume.

Main 5 boilers are equipped with a bitmatic heat exchanger, which simultaneously heats both running water and coolant. This is implemented due to the fact that there is another pipe of the smaller diameter that flows from the tube from the heating system, according to which water supply flows.

In front, an electronic control board has been installed. In the electric circuit printed in the operating manual, it is shown to which places all the elements and sensors of the boiler are connected to it. You can figure it out on it how the electric part of the equipment works.

Outside, a steel casing is installed, on which there is an electric control panel with the buttons on and select the mode of operation from below. In modern models, a display is installed for the output of technical data and error codes in case of malfunction.
