If you are experiencing problems with an existing central heating system, just because your radiators are not heating up properly doesn’t mean that they need replacing. The problem could be with the hot water boiler, or with a blockage in the piping. Very often, all that is needed is to bleed the radiators themselves.

Bleeding your radiators

Bleeding radiators is something that almost anyone can do. It’s a very simple procedure that doesn’t require any specialist knowledge. Radiators need bleeding when sections of them don’t warm up when the heating system is switched on. The tell-tale sign is when the bottom of the radiator is hot, but the top is cold.

This is an indication that the air is trapped at the top of the radiator, preventing the hot water from reaching it. It needs to be bled. For easy to follow instructions on how to bleed your radiators yourself, please click here.
