A regularly serviced boiler is safer, more efficient and likely to have a longer life. Annual servicing not only helps prevent costly repairs and unexpected breakdowns during the colder months, but also contributes to a more reliable heating system. Moreover, scheduled maintenance can lead to reduced energy bills and a smaller carbon footprint, making it an eco-friendly choice. In this blog, we will explore how long a boiler service typically takes, the factors that can influence the duration and what you can expect from this vital maintenance service.
What are the different types of boilers?
Firstly, it is useful to understand the different types of boilers commonly used in homes and buildings, each suited to different heating needs and set-ups. These include:
- Gas boilers – use natural gas or liquified petroleum gas (LPG)
- Oil boilers – run on heating oil
- Electric boilers – use electric elements to heat
- Biomass boilers – use renewable fuel sources, such as wood chips or logs
- Solid fuel boilers – burn coal or wood
- Hydrogen boilers – are less common, but as the UK moves towards greener energy solutions, hydrogen-run boilers may become more popular.
How long does a boiler service take?
The average time it takes to service a standard boiler takes a minimum of one hour. This time period varies depending on the type, size, age and condition of your boiler, as well as if there are any pre-existing issues, such as pressure problems or leaks, which need to be addressed.
For example, if you have a conventional gas boiler (i.e. a boiler system that provides both central heating and hot water) the servicing may take longer, owing to the fact that they involve additional parts, such as hot water cylinders or cold water tanks. This means more checks and cleaning steps for the engineer, potentially extending the service time to over an hour.
What does a boiler service include?
As a homeowner, landlord or building manager, you can expect a boiler maintenance service to include:
- A visual inspection of the boiler and pipework for any obvious signs of damage or corrosion.
- An assessment of the main components, including the burner, heat exchanger and controls for proper operation.
- Cleaning of the parts where necessary to ensure no blockages or build-ups occur.
- Testing the gas pressure and flow tests to make sure the boiler is working efficiently and safely.
- A flue inspection to ensure safe emissions and prevent carbon monoxide leaks.
- A check on the boiler system controls to ensure correct settings and calibration.
Will an oil boiler take longer?
Servicing an oil boiler typically takes longer than servicing a gas boiler for three reasons:
- Oil boilers generate soot and residue during combustion, which means the internal components, such as the heat exchanger and burner, need more thorough cleaning compared to gas boilers, which burn more cleanly.
- Oil boilers often require replacement of fuel filters and nozzles to ensure smooth operation, which can add to the service time.
- An oil boiler service can include an inspection of the oil storage tank and its connections to ensure there are no leaks or blockages, which is an additional step not needed for gas boilers.
What to expect from a boiler service
Homeowners, landlords and building managers are responsible for scheduling regular boiler servicing. The service engineer will deal with any minor issues they come across during the servicing, for example, low boiler pressure, but may need to do a follow-up visit to deal with major issues, particularly if new parts are required.
Gas boilers are required to be serviced by a Gas Safe registered engineer, a certified engineer legally able to work on gas appliances in the UK.
Once the service is complete, the customer will receive a service report detailing the work done, the condition of the boiler and any recommendations for future maintenance.
When should I get a boiler service?
The majority of boiler manufacturers recommend servicing boilers once a year to maintain warranty and ensure efficient functioning.
Immediate signs that your boiler may require servicing are:
- banging or whistling noises coming from the boiler,
- sudden changes in water pressure or temperature,
- leaks or unusual smells coming from and around the boiler.
Summer is often the best time for servicing your boiler. During the winter, your boiler is in full use, working hard to keep your home or property warm and comfortable. Scheduling maintenance during the summer months ensures that your system is checked and any necessary repairs are made before the colder weather arrives.
Why you should carry out a service every year
Regular annual boiler servicing offers numerous advantages, including:
- Improved efficiency and lower energy bills – scheduled servicing ensures the boiler operates at maximum efficiency, which can lower household energy bills. Regular cleaning also ensures the system heats water and the home faster with less fuel consumption.
- Preventing breakdowns and costly emergency repairs – servicing helps identify potential problems before they turn into serious issues. For example, a worn-out valve discovered during a service can be much cheaper to replace than a complete boiler breakdown.
- Extending the lifespan of your boiler – well-maintained boilers can last up to 15 years or more, whereas neglected systems may need replacement much sooner.
- And most importantly, safety – regular inspections help prevent dangerous issues such as carbon monoxide leaks, which can be deadly if undetected in gas boilers.
