Radiator bleeding purges air that has accidentally gotten into the radiator’s coils. All radiators must be bled on a regular basis, as the heating and cooling of water naturally releases air bubbles. You can try radiator bleeding if your heater seems to be functioning poorly or not heating as well as it did before. A radiator works by heating water in a series of coils that effectively warms the air that comes in contact with the metal surface. When air gets in the radiator, it rises to the top and displaces some of the water. Air doesn’t conduct heat nearly as efficiently as water, therefore it is both costly and wasteful to run your radiator with air trapped inside. Experts on home maintenance and energy efficiency recommend radiator bleeding regularly at least twice a year. During the winter season when you use your radiator daily, or have to refill it with water, you may want to bleed your radiator more often.
