We’ve all been there, teeth chattering as we stare resentfully at our faulty boiler. There’s never a good time for it to happen- when your boiler breaks the nightmare strikes. The nightmare and hassle of cold water, no central heating and the inconvenience of getting it fixed. Luckily, our team of efficient and reliable boiler engineers are always on hand to get to you as quickly as possible should your boiler under perform in any way. We’ve put together a list of top 10 boiler problems you shouldn’t let go unchecked.
potential causes include broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels. This could be caused by a variety of things including broken airlocks, failure of motorised valves or low water levels.
* No heat or hot water: Considering generating heat and hot water for your home are the primary functions of a boiler, lack of these things might be the first thing that springs to mind when you think about boiler problems. Broken airlocks, defective diaphragms failing motorised values and low water levels could account for cold water and the absence of heat.
* Kettling: This may sound like your boiler has decided to go on strike and put its feet up with a brew, but kettling is in fact what occurs when lime scale deposits build up on the heat exchanger (what the boiler uses to heat up hot water to function- in areas of hard water and restricts the flow. How do you know when kettling is happening to your boiler? You’ll hear an odd rumbling noise akin to a kettle. Don’t worry you’re actual kettle needn’t get kettle envy. Solutions to kettling and from preventing it from happening again include (but aren’t limited to) : replacing the heat exchanager, using a power flush system and fitting a Magnetic and Electrolytic Scale Inhibitor.
Professional job: Some of your boiler and heating problems can be fixed by you but often it’s best to call a qualified engineer.
* Decline in pressure: No one likes being under pressure but you could be under pressure to replace the pressure relief valve in your boiler if it’s experiencing pressure loss. Alternatively a water leak somewhere in the system is the most likely cause of reduced pressure.
* Your boiler emitting bizarre banging or gurgling noises: No your boiler isn’t possessed and no you haven’t just stumbled into an scene in a Paranormal Activity film. Several factors could be responsible, such as fast approaching pump failure in older boilers, or low water pressure and kettling, although the most common reason is air in the system.
* Pilot light keeps extinguishing: A draught that keeps blowing the pilot out, a broken thermocouple or a sediment build up on the light itself could illuminate the reason why your pilot keeps going off on your boiler.
* Dripping or leaking: There’s nothing more agitating than a constant drip, drip, dripping noise to keep you awake at night. A range of issues could be the culprit, with the location of the leak needing to be identified in order to determine the reason for the dripping.
* Boiler unexpectedly switching off: A pesky problem your boiler could experience. A number of factors could explain this issue such as, a fault with the thermostat, low water pressure, air within the system or a substantial lack of water flow thanks to a closed valve. Sufficient circulation of water around the system might be amiss if the pump us damaged, resulting in the boiler turning off.
* Condensate pipe freezing: The freezing of this section of the boiler system happens because the pipe is located outside the house so it can reach a drainage point and during the winter the acidic water inside it is vulnerable to freezing. When this freezing happens a block is created water fills up inside the boiler as a consequence, though fortunately a trigger can be switched on to shut down the boiler should the water reach a certain point to avoid the entire system being flooded.
We would strongly recommend getting a qualified engineer to come out and fix the problem, particularly if you can’t pinpoint where the frozen section in the piping is. If you do feel comfortable dealing with it though, you can either apply hot water heated in a microwave or kettle (not boiling water!) from an appropriate container, for instance, a watering can, directly to the outside of the pipe or place a hot water bottle or heat wrap on the part of the pipe where the frozen water lies. Always contact an qualified engineer if the condensate pipe you are trying to thaw is above ground level.
Where your pipes run outside your house, they may suffer from pipe freezing and need thawing.
* Thermostat Trouble: Like most devices, the older your thermostat gets the less effective and precise it is likely to become, turning the heating on and off by itself and misreading temperature settings. The best course of action is to invest in a newer more energy efficient thermostat.
* Radiator failing to get hot: Air can accumulate in the radiator causing it to be warm at the bottom but cool at the top. This can be resolved by simply bleeding the radiator. If it is deposits of sludge that have developed in the radiator, stopping the flow of hot water to the radiator, a power flush or chemical clean may need to be carried out by a professional to cleanse the system.
Your home should be your cosy sanctuary. If your boiler is giving you grief or you’re experiencing one of the above issues call us to arrange for one of our skilled engineers to fix the problem for you.
