Frequently Asked Questions

If this happens, it might be a result of low pressure or blockage in the system, which is restricting the flow of water. In some cases, there could be a fault with a closed valve, thermostat or aa pump causing the water not to circulate properly. We recommend contacting us for assistance in diagnosing and repairing the fault by a Gas Safe registered engineer.
The most common causes of leaks and boiler dripping water are faulty internal components, this includes but is not limited to issues with corrosion, broken pressure valves, pump seals, or loosen pipe connections. We recommend calling out our Gas Safe registered engineer, who will diagnose and fix the problem for you and stop any potential dangers. You should never try to fix a boiler yourself, always call out for professional help.
Kettling sound from your boiler ( similar to a boiling kettle ) is usually caused by limescale or sludge buildup inside the system. It often happens in areas with hard water. The deposits build up in your boiler or pipes can block or restrict the flow of water inside the system, which can result in overheating and weird noise. It is best to treat this as soon as possible because it might result in more severe boiler damage and higher costs if your boiler needs replacing. We recommended calling our team as soon as you notice kettling sounds from your boiler. Our engineer will drain your central heating system and remove limescale and sludge buildup. For more information on this method, please visit our Power Flush section.
Worrying noises from the boiler are usually caused by low water pressure, a faulty pump or air buildup in the system. The type of sound in your system can narrow down the source of the problem. Banging noise could be a result of imminent pump failure, and this happens most often in old systems that have not been serviced regularly. We highly recommend contacting us to book our Gas Safe registered engineer for a professional diagnose of the problem as soon as possible.
The blue flame that always stays lit is called a pilot light. If this pilot light keeps turning off, it will stop your boiler from working. It can be caused by a broken thermocouple, which would stop the supply of gas to your boiler. Sometimes also the problem could be a draught blowing the pilot light out or a deposit built up in the pilot light. Always remember that you should never carry out any work on your central heating system. There is one thing that you could check yourself before calling out an engineer: Check if your other gas appliances are working and that your gas stopcock is on. You can always give us a call, and we will be more than happy to help you.
The most common causes for this to happen are faulty airlocks, diaphragms, motorised valves, thermostat or low level of water in the system. Your heating system might require a new part fitted to be working correctly again. Give us a call today for professional advice. If necessary, we will book a Gas Safe registered engineer for a professional diagnose of the problem as soon as possible.
It is straightforward to check the pressure of your central heating system; just take a look at the pressure gauge on your boiler. Low pressure ( below 1 ) will cause your central heating system not to work properly. It can be a result of a few potential reasons. Some of the reasons for this to happen could be a water leak in the system, recently bled radiators or a faulty pressure relief valve. We recommend contacting us for assistance.
All condensing boilers ( combi, system or regular ) have a condensate pipe transporting excess water away from the boiler. During winter it is common for the water to freeze and cause a blockage. If this happens, your boiler will most probably display a warning or a fault code. Feel free to give us a call; we will be happy to assist.
It might be a sign of a faulty thermostat when the heating is turning on and off when it is not supposed to. If your thermostat starts to malfunction or loses its accuracy, it will probably need to be replaced. Give us a call today for professional advice.
If some of your radiators are not getting hot, then they might need balancing. This procedure can also be done without the help of an engineer, but only if you feel confident doing it. If only the bottom of your radiator is getting hot then it might need to be bled, it is not a difficult task, and it does not require an engineer. In some other cases, there could be a build-up of sludge or air in your central heating system. Our professional engineers can remove this build-up by a process called Power Flush, and this is something that you should not try yourself.
All of our installers are fully trained, and qualified Gas Safe registered professionals.
