What's Included In Your Service
A visual check of the boiler and flame, if possible
Checks on the flue (externally and internally)
Checking the operating pressure and / or heat input
Checking safety devices
Check case seals form an effective seal
Boiler casing removed to check all main boiler components (burner, heat exchanger, main injector,spark / sensor probe)
Boiler fired safely to identify any working faults
Boiler parts cleaned, if necessary
A service report showing everything the engineer has done
Prior to any work being carried out it is important to agree with your registered engineer their scope of the work so that everyone is clear. For example, there are differences between an appliance service and a safety check and equally between a safety check of appliances and a safety check of the whole installation, which includes all pipework and appliances.
What is an Appliance Safety Check?
An appliance safety check at a minimum includes all of the checks and tests to ensure the appliance is safe to operate, for example:
- It is correctly set and adjusted to ensure the gas is burning correctly It is of a type suitable for the room in which it is located.
- It is physically stable, securely fitted and properly connected to the gas pipework.
- There is an adequate and permanent air supply suitable for the appliance type installed.
- Any flues or chimneys are operating correctly
- All safety devices function correctly
What is an Appliance Service?
An appliance service will include all of the above checks and tests and any other specific checks, for inspection and/or cleaning of the appliance as specified and detailed in the appliance manufacturer’s instructions. This may include:
- If appropriate, an analysis of the combustion exhaust gases to ensure the appliance is burning the gas safely.
- A check of the condition of the appliance including (but not limited to): the effectiveness of any seals, gaskets, the cleanliness of heat exchangers etc. and checking for any signs of heat or other distress.
This is not an exhaustive list and servicing requirements will vary across appliance types and models.
Note: Some appliance servicing regimes provide an interim performance check (annual) to be used in order to determine the degree of dismantling the appliance and the level of servicing required.
When assessing an unsafe gas appliance, all engineers will follow the Gas Industry Unsafe Situations Procedure (GIUSP) which provides ‘best practice’ advice to engineers on how to deal with specific gas safety concerns.After they have worked on the appliance, the engineer may issue you with a report detailing the checks they’ve carried out. This could be a Gas Safety Record, depending on what work they have done – however it's not a legal requirement for this to be issued, so it’s probably best to check with the business beforehand what documentation they’re likely to provide.
These all play an important role in the safe operation of gas appliances, allowing products of combustion to escape and ensuring a high level of ventilation. As cold as it might get during winter, never block up these airways – this could result in a build up of carbon monoxide in your home.
Chimneys will need to be checked every year for blockages (such as birds’ nests and debris) which can prevent dangerous fumes from escaping. The Gas Safe registered engineer will be on the lookout for these
.If you live in a property with a shared flue or chimney, you’ll need to share responsibility with others to ensure they are checked annually as it’s possible for carbon monoxide to enter properties through these shared vents.
On average, a boiler service should take from 20 - 40 minutes.
