How to fill the heating radiator with water

In order to launch any heating system, it will certainly be filled with a coolant. How? About this below.
Before filling the heating system with the coolant, it is necessary to make sure that there is no air in it.
Start removing gas from the system you need from the mains of the boiler room, read more here -

In order to come out of the circulation pumps, it is enough to just open the screw in the front of the pump. After the fluid hiss becomes heard, the screw can be blocked. After that, it is necessary to release air from radiators. Starting with the lower, finish - upper. Such a sequence is necessary in order to have no need to release air again.
Running taps and valves that are on the branches of the return pipeline must be kept closed. You can open only air workers, it will be necessary to close them after the appearance of water.
The fluid is injected into the return highway using the power of the feed pump. Aerial cranes, at this time, are kept closed, in order to accumulate the air to be released later, in a couple of minutes.
After the reverse highway is filled, you can open the jumper valve. After all branches of the feed pipeline are filled, you need to wait a couple of hours, in order to make sure that there is no gas in the system.
Circulation pumps are included at a pressure of two atmospheres. If necessary, you can once again check the system for air.
As a result, the pressure in the heating system should be equal to one and a half atmosphere, and if the water is hot, it can rise to two atmospheres.
If the heating radiator is filled with the coolant in the cold season, at a temperature of less than one degree Celsius, water should be heated to 20 degrees, and the room is heated to positive temperature values.
When installing the heating system, trash and dirt can be accumulated in the pipeline. Therefore, before exploitation, it is necessary to wash the heating equipment.
When filling in the heating system, it is necessary to gradually open the cranes and be sure to monitor the pressure.
