Fast filling of heating services with water does not become rare the reason of formation of air locks: vials of gas get to utilities together with water. It is possible to remove the air which has accumulated in heating network in several ways.
- - manometer
- - metalwork tool
1. Check working pressure in heating appliances, having used the manometer. The modern boiler equipment is equipped with the built-in manometers. For individual housing constructions the indicator 2-3 bars is considered normal.
2. Add necessary amount of water that pressure has reached norm to heating services. Include heating boiler.
3. Open manual air separators on radiators. Each radiator used in heating system has to be equipped with such air separators. Manual components, as a rule, are installed at faces of radiators. Their advantage consists in simplicity of service and operation. They are regulated by gas pipe wrench or the screw-driver.
4. Wait until the system is filled with water. Close air separators after from radiator it is watered. It demonstrates that there is no air in heating services any more.
5. Equip heating system with the automatic air separator. Delete air locks from heating system during its filling and periodically – during operation of communications. It is considered one of the most effective ways multistage which provides mounting of several air separators which are mounted in several places. Advantage of multistage system is that air from each radiator (group of radiators) is removed separately.
