The Top Three FAQs about Boiler Servicing…

If you are arranging a boiler service, and you are not sure why you need it, what’s involved or how long a boiler service should take, then read on!

Why do I need a boiler service?

Since most of us enjoy hot water every day, it’s important to remember our boilers are working hard year-round, not just during winter.

Chances are, you won’t know about a problem with your boiler until you are left with no heating or hot water during a cold spell!

Whilst you are not legally required to have an annual service unless you are the landlord of the property, fixes and replacement boilers can take days or even weeks during the winter months when demand is high.

A boiler service will uncover any brewing issues and give you the opportunity to arrange a repair if necessary. A boiler that is not working to its full potential can also be hazardous to your safety, and can spike your energy bills.

If your boiler is under warranty, or an insurance policy, then it’s likely this requires a service every 12 months to remain valid.

What happens during a boiler service?

A registered Gas Safe Engineer will spend roughly half an hour carrying out the necessary checks. Engineers use digital devices nowadays (gas analysers). A legit boiler service can not be conducted without one.

The engineer will;

  • Visually check of the boiler and flame, if possible.
  • Remove the boiler casing to check all main components (burner, heat exchanger, main injector, spark / sensor probe)
  • Check the flue internally and externally
  • Check the operating pressure and / or heat input
  • Check safety devices
  • Check case seals for an effective seal
  • Test the boiler fires safely to identify any working faults
  • Clean boiler parts if necessary

You will be given a Gas Maintenance Certificate report by the engineer, detailing the checks they have carried out.

What’s the difference between a boiler service and a boiler repair?

A boiler service is the process of checking and identifying any issues, reducing the risk of your boiler breaking, and you needing to arrange a breakdown call out.

A boiler repair is what you need if any issues are uncovered during the boiler service. A boiler repair will require extra time outside of the 30 minutes that the boiler service takes. It may also require new parts. Therefore you will need to book more of the engineers time to carry out the repair.

A typical example of a boiler service leading to a boiler repair would be when the gas analyser device alerts to a high CO2 reading. Further investigation must take place, followed by repairing your boiler which could include parts, such as new rubbers for the flue.

Hampton Heating and Plumbing say:

To prevent being left cold, and to prolong the lifespan of your boiler, book your service early and be sure to book it yearly!
