Just like cars central heating systems need to be maintained to be sure they are working safely and efficiently. If you have had a new boiler recently installed it still needs to be annually serviced otherwise any warranty you have will in most cases be invalid . If you have an old system a simple health check up could help extend it’s life or determine whether a new more efficient alternative is a better option.
Top 5 things to look out for?
You can visually check your boiler and central heating system at home to see if it might require attention.
1. Visually check your boiler for signs of corrosion underneath or leaky pipes. During operation your boiler should run quietly. A noisy (banging/kettling) boiler could be dirty or need replacement parts. It will also not be operating efficiently.
2. Check that you have thermostatic radiator valves on radiators and that they are working affectively (are not stiff or leaking). It is a good idea during summer months to leave them fully open instead of shut so that when you turn your heating on in the winter your TRV’s work. If they are not responding and you have cold radiators then try ‘wiggling’ the pin to unstick the valve.
- First set the head of the valve to it’s highest/hottest setting.
- Then unscrew the head and remove it to access the pin.
- Give the pin a gental wiggle with your finger or set of pliers.
- Replace the valve head again with it set to highest/hottest setting.
- Set the valve to the desired temperature and see if if the radiator now becomes hot. If nothing happens then call out plumBrighton to either replace the valve or tackle a bigger problem with your system.
3. Check that you have a thermostat and programmer. This enables you to set timed heating periods and temperatures to control your heating requirements.
4. Check for cold spots or cold radiators. If cold then there could well be sludge in the system which will need to be cleaned. A dirty system is an inefficient system.
5. Finally check your system as a whole. Is it right for your use? You may have an old gravity system with a hot water cylinder when a combination boiler might be better suited. Alternatively you might have extended and added another bathroom meaning that your current combi cannot cope and a unvented cyclinder might be a better bet.
Of course you can always give plumBrighton a ring and we can come and give your central heating system and boiler a full health check. See our heating pages for more details.
