The boiler is one of those things that you simply don’t think about; that is until something goes wrong! As soon as your boiler does go wrong, one question will be at the forefront of your mind and that is ‘How much is it going to cost?’Aside from the inconvenience of having no hot water and no heating, fixing a boiler can be a pricy business. Find out the most common causes for boiler malfunction and failure right here.
One of the most common symptoms of a broken boiler is no hot water or heating, and this can be caused by a variety of problems such as low water levels, broken airlocks and failure of the motorized calves within the boiler. A sign that all is not right with your boiler and that you may face no hot water and heating is the boiler switching itself on and off since this can be caused by the same things. In some cases though, it can be as simple as a fault with the thermostat.
Speaking of the thermostat, the older it is, the less accurate it may be which can cause issues such as incorrect temperature readings, and the heating turning itself on and off before or after it should be. In this case you will need a new replacement thermostat. You can purchase this online and save yourself money, but unless you know what you are doing, it is best to get in a professional heating engineer to install it.
Another common affliction of boilers is that they can make unexpected tapping and ticking noises when you switch the heating on, or alternatively run water. The root of this problem is typically air in the system, although it can also be a faulty valve. A professional will of course be able to more accurately diagnose it for you, and hopefully fix it.
Banging, gurgling and whistling can be a sign of a different problem for your boiler though known as kettling. Kettling is when lime scale or sludge builds up on your boiler’s heat exchanger and is usually only an issue in hard water areas. This lime scale build up can restrict the water flow, meaning there is less water to heat so it is overheated and that’s what makes it whistle and steam.
If you find that your water pressure is dropping then it can be a sign of a leak, and not just in the boiler, but more likely in the pipes – this can even mean outside! One way to check if your system has a leak is to fill the boiler up with water and monitor how quickly it drains out. If you have your fears confirmed, then get a professional out as soon as possible who may (hopefully) have a better idea as to where to seek the leak!
And finally if your radiators aren’t getting hot then that actually might not be so much a boiler problem. When you are checking the heat of the radiator, if the top is cold but the bottom is nice and toasty warm, then it is probably an issue with air being trapped in the radiator. Using your radiator key, slowly turn the valve at the top of your radiator slowly until you hear hissing coming out; as soon as water starts to spurt out, quickly close it again. This should solve your problem.
