My neighbor was complaining the other day about his banging radiators and how they had been doing that for over a year!
He was surprised when I advised him that you can bleed a radiator to let the air out and stop the noise. Yes thats bleed, not as in blood but as in letting the air out.
Air builds up in radiators as waste deposits and corrosion create waste gases, they are designed with a bleed valve to allow this air build up to escape.
A towel to shield your hand, a bleed valve and a quarter turn of the wrist and the task is completed.
Once done remember to close the valve and you should be ok for the next year or two.
