Understanding the basics of self-bleeding radiator valves is not rocket science, it actually quite simple. All radiators operate to control the temperature of an engine, a room or an associated device. Each radiator has a sensor to determine temperature and a valve to control how much liquid will be passed through. For a warming effect, warmer liquid is allowed to pass through. For a cooling effect, the liquid is allowed to sit and settle, and no warm liquid is allowed to pass through.
An important part of this process is the amount of air contained in, and around, the radiator. As a rule, you want the amount of air getting into your radiator to be as little as possible. This is because air does not conduct heat as well as liquid. Traditional radiators require you to check your radiator frequently and to manually “bleed” the air from the system using the valves.
However, modern radiators tend to be self-bleeding. This means that these radiators have superior sensors and valves that not only detect temperature, but also to release air from the system itself. This allows homeowners to focus on other things. Self-bleeding radiators may also save money, because they efficiently heat your home during the colder months of the year.
