CASE STUDY: An Annual Boiler Service

An annual boiler service is an important part of boiler and heating system maintenance. It is also a condition of boiler warranties, so you will need to make sure your boiler is serviced annually to make sure warranty is valid. The heating engineer who carries out your annual service must be Gas Safe registered. You can check them out on the Gas Safe register website.

We were asked by a local householder to do his annual boiler service. We explained the process to him.

Step 1 – Visual check. The heating engineer will start the annual service with a visual check to make sure that the boiler and associated pipework is installed and positioned correctly. They will then check that your boiler is working correctly and identify any initial problems.

Step 2 – checking inside and cleaning. The engineer will remove the boiler casing to take a look its components. They will check the burner, main injector, condense drainage trap, seals and fans. They will clean inside the boiler and inspect the water and gas pipework to make sure everything is working correctly.

Step 3 – checking the flue and combustion. The engineer will check that the flue is safely fitted and not blocked. They will use a flue gas analyser to make sure the boiler is burning the right mixture of gas and air. This is to check that the boiler is operating efficiently and safely.

Step 4 – explaining what they have done. The engineer will tell you if the boiler does not meet any building and safety regulations. Make sure that they explain any repairs or maintenance work they need to do and that any parts used come from a reputable manufacturer, ideally from the boiler manufacturer.

Most boiler services should last around half an hour and you should receive a full service report. Only sign this report if you are happy with every element of the service your engineer has carried out.

Your engineer should fill in the service record which is part of the user guide and includes the Benchmark checklist. This document is needed if you ever need to make a claim during the length of your boiler warranty.

CASE STUDY: Landlord Gas Safety Certification

Under law, all landlords are required to have all gas appliances and pipework installation checked every 12 months, with a certificate to prove compliance. We were approached by Mrs Deakins, a landlord with three properties. She wanted us to perform the inspection, but first asked what’s included in a Landlord Gas Safety Inspection?

We explained that Oor Gas Safe Registered engineers will check the following during a gas safety inspection:

    Gas tightness in appliances

    Standing and working pressure from available test points

    Compare burner pressure and gas rate against manufacturer’s data plate

    Satisfactory provision of all necessary ventilation

    Test flue flow to ensure removal of products of combustion

    Satisfactory operation of all flame failure devices

    Effectiveness of stability brackets

    Identify evidence of noncompliance and report to corresponding authorities.

A tightness test on the entire system will need to be carried out for Landlord Safety Record inspections. An appliance is not recognized as having been checked until all of the above actions are completed. We test all appliances for their CO value using a combustion analyser. We will then issue a CP12 certificate with a unique serial number.

Know she knew what was necessary, she booked us to carry out the inspections which we did over the following two weeks once the tenants allowed us access to the various properties. We issued the correct certification and Mrs Deakins and the tenants knew they were safe for another year.

CASE STUDY: Boiler Replacement

Early in February, Mr Charles called us to discuss his options regarding his boiler which was operating inefficiently. Mr Charles felt that his energy bills were too high and asked if it could be replaced for a more efficient model.

After a home survey we produced a quotation for an energy efficient boiler and controls. We also suggested a flush would be beneficial to ensure maximum water circulation through the system which would ensure the heat output from radiators would be optimum.

Mr Charles accepted our quotation and we began working on his new installation. We firstly removed the old boiler from the premises, then replaced it with a much more efficient boiler, upgrading the pipework as necessary. The boiler was commissioned successfully, and tested to ensure that the correct operation of the pump.

At the same time, we completed the jet flush of the system, clearing rust and sludge from the system, and the boiler was fitted with a filter.

Mr Charles contacted us a short time afterwards, thanking us for our professional level of service. He was also impressed with the way the team that worked in his house cleaned up after themselves at the end of the project.
