As the heating season approaches, owners should not forget one thing: to bleed the radiators in good time. This is because air in the system can significantly reduce the heating output - the heating hisses, remains cold at the top and consumes an unnecessary amount of energy. The good news is that you can fix this problem yourself in just a few simple steps - and save money.
How can you recognize air in the radiator?
Typical signs of air in the radiator are gurgling noises, uneven heat distribution or significantly lower heat output. In such cases, bleeding is the first and simplest measure - without the need for a tradesman. All you need is a bleed key, a small container and a cloth.
How do I bleed the air properly?
The best time to bleed is when the heating is switched off and the radiators are cold. The bleed valve is usually located on the side of the radiator. As soon as air escapes and water flows in, the radiator is free of air again. The water pressure in the heating system should then be checked - it may need to be topped up. If you have several floors, start at the bottom and work your way up.
Why it's worth it
An efficient radiator not only reduces energy consumption, but also ensures even heat and increases living comfort. In apartment buildings, owners should have their radiators checked regularly or have them bled by a heating service provider - especially before the heating season.
Conclusion
Venting radiators is a quick job - but crucial for energy efficiency. Owners who check and act regularly save on heating costs and extend the service life of the system.
