There are two potential types of blockage that can occur inside both modern and older central heating systems. The first of these is a type of sludge which is an accumulation of all the grit and grime that flows through your radiators each day and eventually settles inside them. These deposits will result in cold spots or patches on the underside of your radiator units right across your property.

The second type of blockage is an air block or air lock that can appear in any central heating system also. The first indication that there might be air inside your central heating system is that you’ll suddenly start hearing some pretty weird noises and bangs from the system as it’s switched on. The “bangs” are the air trapped in the system being forced through a pipe and for want of a better description this is like your central heating system burping – it’s trapped wind causing the problem.

To remove the air from any heating system it will need to be “bled” to remove it and although you can try doing this yourself it’s better and safe to call in heating and plumbing specialists like the team at ADI.
