Before heating season it is necessary to lower air in batteries, otherwise batteries can remain cold even with completely open valves. Besides, various sounds from batteries, for example, silent gurgle can be heard that is sign of availability in air radiator. In heating system owing to congestion of large amount of air in the battery there is no circulation and in that case air it is necessary to lower surely.
It is required to you
- - capacity;
- - key for the battery.
Instruction
1. First of all it is necessary to open the thermostat valve till the end. On all batteries there is special valve for air descent, there is it usually on the opposite side of the battery from the thermostat valve. Here the key for the battery which can be found in any construction supermarket is useful. The valve needs to be opened, but at the same time it is necessary to listen to sounds. That air has begun to go out of the battery the hissing sounds signal. As soon as all air goes out of the battery, from the valve water will begin to flow therefore it is better to put previously under the battery rag, or to substitute the capacity that water in it gradually flew down under valve. Usually water pressure very weak and to you it is not necessary to be afraid of flooding.
2. The batteries manufactured of aluminum have property of the increased gas generation therefore for such batteries the installation differs from standards a little. One edge of radiator rises on distance about 0.5 cm, then in raised edge it is possible to establish otvodchik safely. The system consisting of the aluminum batteries which do not have otvodchik will zavozdushivatsya every week. At the same time it is impossible to lower air manually as foam begins to go. The only way out – weekly draining of all system. To avoid troubles, it is necessary to get and establish the automatic otvodchik of air intended for the radiators made of aluminum.
3. If after air descent the radiator all the same does not heat, or heats not for long, then it is necessary to blow or wash out batteries. In that case if heating services autonomous, it is worth checking whether completely it is filled. When water acts as the heat carrier, it well extends, and at its temperature reduction becomes a little.
4. Cases are different, and for houses to autonomous heating, perhaps, it is required to lower water through broad tank. The tank always is in the peak point of heating services, most likely, it can be found on building roof. Before it the house should be disconnected from heating, having closed latches. To wait for about half an hour and only then to open the crane on broad tank, water in system will be banished and in case of availability of air will be obviously heard as it filters from the crane of broad tank. There is small probability that the air lock will leave independently at increase in temperature of the carrier, for example, if the system begins to boil.
