An automatic air vent can significantly increase the efficiency and safety of your heating system. In the new entry, we explain how this element works and what function it plays in the entire system.
Air in the central heating system is a common but very annoying problem. Air can enter these systems in various ways - e.g. through leaks, plastic pipes or with the medium during filling. Sometimes air locks also occur as a result of errors such as filling the installation too quickly.
An air-infested installation does not function properly, and its users may notice many disturbing symptoms. In the case of central heating installations, these are most often strange sounds coming from pipes or radiators - e.g. knocking, humming or gurgling. Air from the radiator may also lead to uneven heating. If it gets into the pump, it may even cause the so-called dry running, which already poses a direct threat to the technical condition of the system and the safety of its users.
Fortunately, air in the installation can be effectively prevented. The most effective and safest method is to install an automatic air vent . But what does it do? How to use it effectively?

Automatic air vent in the heating system
Automatic air vents can be installed in various installation locations. Example locations for this item include:
bathroom radiators;
other wall radiators;
tops of installation risers;
air heaters;
expansion vessels;
heating boilers.
The automatic air vent may be part of the central heating installation, but it is also found in installations with a solar collector (models such as FLEXVENT Top Solar ) and in underfloor heating. It is important that it is adapted to the specific operation of the installation. This concerns operating parameters such as maximum temperature and operating pressure. If you have problems selecting the right product, you can seek help from our advisors.
Purchasing a breather costs several dozen zlotys. Top models like FLEXVENT automatic air vent by FLAMCO MEIBES they cost about PLN 70. There is an argument for its installation in the heating system 
many arguments. The most important thing is:
convenience – this type of air vents are practically maintenance-free;
versatility - it can vent both individual radiators and large sections of installations;
efficiency – works twice as efficiently as other solutions available on the market;
possibility of replacing the air vent without having to remove water from the installation;
correct operation even despite contamination - the hole is opened by a lever activated by a falling float;
durability and reliability.
How does an automatic air vent work?
The most important element of the automatic air vent is a float immersed in water located in a cylindrical body. If there is air in the installation, it also enters the vent, causing the water level to drop. This, in turn, causes the float to fall and open a small hole through which air can escape. After this operation, the water level and the float are raised again and, consequently, the hole is closed.
How to bleed the automatic air vent?
Venting of the installation equipped with an automatic air vent is automatic - so no user intervention is necessary. Any problems with the operation of this element are the result of damage or incorrect installation. Therefore, if we do not have the appropriate knowledge and tools, this task should be entrusted to a proven specialist.
A properly selected and correctly installed automatic air vent will provide many years of trouble-free operation. It will also significantly increase the comfort and safety of using the heating system.
