Boilers today are very sturdy and durable, but they are not bulletproof and things can and do wrong. In the colder months, boilers often break down after being off for long periods of time during milder weather. During freezing temperatures, they are often used to their limits.

Common boiler faults:

  • No hot water or heating
  • Pressure issues
  • Boiler switching off
  • Strange or loud noises
  • Leaky boilers
  • Pilot lights gone out
  • Freezing
  • Faulty thermostat
  • Radiators not getting hot

It is not always obvious in working out the exact fault, without us coming out to take a proper look. Modern boilers often display an error message that can help identify the particular issue, so remember to note this down before giving us a call.

Remember, NEVER attempt to fix a boiler by yourself – a boiler repair can only be done by a gas safe registered engineer.

Brief examples of what might be wrong with your boiler:

Leaks: A leak from the boiler can be another issue and the source of the leak will help determine the cause of the breakdown. The most common cause of a leak are faulty components such as the pressure valve, pump seal, pipes or the tank.

Pilot light: When the pilot light goes out, causes could be a draught, broken thermocouple or possibly a deposit build up.

Freezing: As mentioned before we get called out during the colder months once boilers have been switched back after the summer. Condensing boiler can have issue if the condensate pipe freezes. The condensate pipe runs from the boiler to outside the house so inevitably is more exposed to freezing conditions. We recommend getting it touch with us so we look at the issue rather than attempting to fix it yourselves.

No hot water: Having no heat or hot water could be caused by a number of reasons such as; low pressure, airlocks, faulty thermostat, valves, a broken diaphragm or another component. You can check this yourself by opening the pressure valves allowing cold water into the system and once the pressure gauge reaches 1.5bar, close off the valves.

Check your Thermostat: A thermostat can be occasionally setup incorrectly so check with your manufacturer first (Heatmiser or Danfoss for example) and ensure your thermostat is working as it should be rather than an expensive call out charge.

Radiators: If some rooms within your home are taking too long to heat up then Powerflushing could definitely help. Having a heating system that is as clean and efficient as possible will help ensure that your entire home is heated during the cold months ahead. If you find that your radiators have spots colder than others then then sludge could have accumulated in your radiator and may need flushed out. This will solve this issue quickly and effectively and your house warm and cosy in no time.

You can prevent these issues every winter by having an Annual Boiler Check done – give us a call on 07542 781131 to find out how we can arrange for you. Also remember that if you are going to be away for periods of time then think about investing in a smart thermostat – you can even control your heating remotely via apps on your smart phone or tablet.
