How long do you bleed a radiator for?

FAQ banner image

How long it takes to bleed a radiator effectively can fluctuate in line with how much air is trapped inside, and the size of the radiators you are bleeding.

In most cases, it will likely take between 20 and 30 seconds to bleed a radiator, but it could take up to a full minute for larger radiators.
