First off what is bleeding a radiator and why do you need to do it? Radiator bleeding is a term giving to the 'act' of removing air that has accidentally gotten into the radiator's coils. When air gets in the radiator, it rises to the top and displaces some of the water. Air doesn't conduct heat as efficiently as water; therefore it is both costly and wasteful to run your radiator with air trapped inside. All radiators must be bled on a regular basis, as the heating and cooling of water naturally releases air bubbles.
So how do you bleed a radiator?
