Noisy Central Heating Solutions
Having a noisy central heating system is annoying and the problem will need to be fixed as soon as possible. The problem is that it is sometimes difficult to determine where the noise is coming from. If you asking yourself, “why is my central heating so noisy?’ here are some solutions:
Banging and clanging pipes – if you are experiencing noisy central heating pipes or a central heating banging noise you will need to check to see of all of the pipes are fitted properly and are tied down properly. Check to see they are not hanging loose and not screwed down tightly enough. Both of these can cause internal banging of the pipes. If the position of pipes is correct you may have a simple problem of pressure and you can try to solve this by first draining and then refilling the system up again. If there is still banging after you have done this you will need to get an installer to put in wider diameter pipes that are better suited to the new boiler.
Humming boiler or a vibrating boiler is a sign that the heating elements are set at the wrong timing or the wrong pressure. First check that the thermostat is working correctly and if it is just slow down the speed at which the noisy central heating pump heats the water. If the pressure is left set too high damage can be caused to the pipes, especially during winter when you will also have clanging and banging noises to contend with.
Gurgling and tapping radiators can be caused by air built up in the radiators which means that each individual radiator needs the air bled out of the system. Just loosen the corner screw for a second until water appears then you know that the air is gone. Tapping can be caused by a lime scale build up. To cure this get some non-acidic cleaner or de-scaler solution and pour it into the expansion tank with the central heating system turned off. If this does not work you may need to have your system professionally cleaned. Remember to hire a professional and qualified engineer to flush out your central heating system.
Remember, if you lack the confidence or experience in checking or amending your new boiler, then you are always better off leaving a noisy central heating system to a professional. A qualified, experienced contractor will be able to locate the problem more quickly and fix it with the skill and ability required, without causing any further damage. Compare a number of different quotes for the best deal, and before you know it you should have a clean, fully functional boiler operating in no time.
