What is a Boiler Service?

A boiler service is a thorough check of all the parts to ensure your system is working efficiently. Your system will also be thoroughly cleaned to prevent blockages. During a service, our engineers look out for any system components that may fail in the near future, this enables you to plan repairs before they become a plumbing emergency. The most important part of a boiler service is checking your system to ensure that it is safe. To book your boiler service with an experienced gas safe engineer, call Bluewater today.

All of our engineers have the expertise needed to provide you with a thorough boiler service. Each engineer follows a standard boiler service checklist which we have outlined below:

Boiler Service Checklist

  • Visual inspection

Your engineer will begin by visually inspecting your boiler. This will involve removing your boilers casing, followed by checking, cleaning and making necessary adjustments to its internal parts. Your engineer will also check for any signs of damage or distress before they become an emergency.

  • Operation and control 

Your boiler includes a number of controls and safety devices. These will need to be tested to ensure they are operating correctly. 

  • Flue and combustion releases 

Construction, termination and the route of the flue pipe from your boiler to the outside of your house will be checked. This will involve ensuring there are no obstructions and that everything has been safely fitted. 

  • Cleaning the main boiler components

The main components of your boiler will be removed and cleaned during a service. This helps the engineer see any noticeable faults and ensure they are fit for purpose. Parts in these checks will include; the heat exchanger, ignition pins, flue ways and main burner. 

  • Further Checks 

Once the initial key inspections have been completed, there are further tests included in a boiler service. These can include:

  • Flame sense device and whether it operates correctly
  • Pilot burner and any cables and probes
  • Measure and recorded gas pressure
  • Measure and recorded water pressure
  • Carbon monoxide check
  • Boiler operation
  • Provision of adequate ventilation
  • Flue effectiveness
  • Heating controls
  • Electrical wiring connections
  • Location of the boiler and nearby combustible materials
  • Full corrosion inspection
  • Gas and pressure flow 
  • Safety devices
  • Complete record 

Your engineer should record each test as they are completed. This should include a record of the boiler pressure or heat input. You will need to keep this information as proof of service to comply with the system warranty. This information will also be handy for future inspections should problems arise. 

  • Switch the boiler back on 

Once the service is completed, your engineer should then switch on the boiler and ensure its ready for use. Any changes to settings will be explained to the customer so they can change these to their needs. Any faults and required repairs found during the service will also be explained.

The Importance of Annual Boiler Servicing

On average a boiler service takes between 30 minutes to an hour. This is a lot quicker and more convenient time span than emergency repairs. Annual servicing is important for maintaining the efficiency of your boiler. Potential repairs can be outlined to you before they become an emergency. Not only does this save time, it can also save costs. Most systems will often need Annual Servicing to comply with warranty.
