9 Signs That Your Boiler Needs Servicing

In order to reduce your energy bills and have an energy efficient heating system, servicing your boiler yearly is crucial. It is also a requirement under the OFGEM regulations to maintain your boiler following the manufacturer’s guidelines. 

There are a variety of signs which may indicate that your boiler needs servicing. Pick up your phone and give us a call if you notice any of the following:

  • Fuel consumption increase
  • Output of boiler decreasing, i.e. not getting the heat levels previously supplied
  • Excessive black smoke production during combustion
  • Excessive visual levels of unburnt fuel within the ash deposit chamber
  • Excessive visual levels of soot within the combustion chamber
  • Excessive levels of clinker within the combustion chamber (clinker is solidified ash which has been taken past its melting point and allowed to cool)
  • Large yellow, wispy flames within the combustion chamber
  • Excessive flue gas temperatures at exit point of boiler 
  • Adverse changes in the O2 content of the flue gasses causing inefficient combustion

If you are unsure of the faults- no problems! We have the ability to diagnose issues through remote monitoring the heat output from a boiler to a property or part of the system. We can also evaluate your system and give you a comprehensive report. Our servicing and maintenance team will be able to tackle all these issues in a quick and reliable way!
