As the saying goes, “if there’s nothing wrong, don’t fix it”, and this is very true for many things in our lives at Flux Pumps. In fact, for many things if something isn’t wrong then we don’t even take notice, like central heating systems or our hygiene. However, as soon as we notice a problem or something seems ‘dodgy’ the topic will become a rather BIG issue! Irrespective of how structured your life is, as soon as the central heating system shuts down a lack of hot water can lead to absolute chaos.
Strangely enough, broken boilers seem to always occur at the beginning of or during winter leaving you without hot water for the months when you need it! This is becomes the boiler has been left inactive for several months prior, and then when the weather becomes colder it is suddenly switched on – can you say expensive problems? Plus, because this is the time many boilers break down you can expect to wait several days before an engineer can come out to check the boiler…a winter of discontent.
Of course, not all boiler difficulties require the assistance of a heating engineer. In fact, some of the more common concerns can be solved without having to call one out at all. Below are some of the most regularly noted issues people have found with their boilers, and using this as a guide you can decide on the least expensive course of action. However, it is recommended that you consult a reliable engineer if ever in doubt.
These are the top 10 most common difficulties you could encounter:
1. A lack of heat or hot water – this is usually caused by broken airlocks or diaphragms. It may also be a motorized valve failure within the boiler, or problem with the thermostat or reduced water levels.
2. Leaks and drips – Leaking and drips can be caused by a variety of things and is completely dependent on where the leak originates.
3. Bangs, whistles and gurgling sounds – strange bangs, gurgles and whistling noises often stem from air in the central heating system. However, it may also be due to a reduced water pressure.
4. A non-functioning pilot light – when the pilot light goes out it usually means that the thermocouple is broken removing the gas supply to the light. It could also be caused by a draught blowing through the pilot light or deposit built up in the light.
5. Loss of pressure – a loss of pressure is often caused by a water leak in the boiler, but it could also be that the pressure relief valve needs to be replaced.
6. A frozen condensate pipe – the best way to rectify a frozen condensate pipe is through thawing. This should be done by a qualified and reliable engineer.
7. Thermostat problems – if the thermostat is showing issues with accuracy or turning on/off the heating when it is not supposed to, then it might be best to purchase a new and more energy efficient one.
8. Kettling – kettling refers to the noise you will hear when water begins to overheat and steam, either a rumbling or a whistling. This is caused by a build-up of lime scale which restricts the water flow in the system.
9. Cold radiators – corroded pipe work in the system may be the reason behind radiators not heating up. The corrosion can cause sludge to gather preventing any flow of hot water. The best treatment is a chemical clean and/or flushing of the system.
10. Unintended switching off – there are various causes for a boiler turning itself off, including reduced water pressure, thermostat problems, poor air circulation and a lack of water flow in the system.
