An efficient central heating system allows you to stay warm in chilly winter nights. However, the efficiency of a heating system depends on the condition of its boiler. Thus, it is important to keep your boiler in good condition and fix it quickly if the need arises.
In this article, we will take a look at the most common boiler problems and discuss what you can do to fix those problems.
1. Strange noise
Sometimes you may hear a whistling, vibrating, gurgling or banging noise coming out of your boiler system. In most cases, it happens due to unwanted air in the system. However, it can also be caused due to low water pressure or a faulty pump.
How to fix it – You can try bleeding the radiators of your boiler if you hear a gurgling sound or check the connectors and adjust the settings if you hear a vibrating or humming sound. If you suspect a more serious problem, you should contact your supplier.
2. Kettling
Hard water can cause a deposit of limescale or sludge to build up inside the heat exchanger of your boiler. This can radiate a sound that is similar to that of a boiling kettle.
How to fix it – The best way to fix it is to contact a registered gas safe engineer who can remove the deposit by flushing them out of your system using professional equipment.
3. Low pressure in the boiler
This is one of the easiest problems to detect. All you have to do to check the pressure of your boiler is to take a look at your boiler’s built-in pressure gauge. Generally, if the needle is pointing below 1, it can be safe to assume that your boiler is suffering from low boiler pressure. It can happen due to faulty pressure valve, leaked water in your boiler system or if you recently bled the radiators.
How to fix it – You should check the system for any visible leaks and call a registered engineer immediately if you find one. If you don’t find any visible leaks, you can try to re-pressurize the boiler system by carefully following the instruction manual. If it still doesn’t help, you should call a professional.
4. No hot water
There can be a number of reasons for this problem like a failed motorized valve, broken diaphragms, thermostat issues, low water levels or airlocks.
How to fix it – Try checking the thermostat or water pressure of your boiler. If the problem is caused due to any other issue mentioned above, you will likely need a new part or replacement. Thus, you should call a gas safe registered engineer.
5. Cold radiators
The buildup of air or sludge in your boiler system can cause your radiators to not heat up properly. In fact, they might stop working altogether.
How to fix it – You can try to solve this problem by bleeding the radiators of your boiler. However, if it doesn’t improve the condition of the system, you may need to call a professional gas safe engineer so that they can flush the system.
