What is an annual gas boiler service?

The boiler service is a yearly visit by a local gas engineer to identify any problems with your system. The gas boiler service can also help to check the whole boiler’s casing and central heating system performance. As well as homeowners being able to see what they need to do themselves in terms of maintenance and efficiency.

Our gas engineer performs a full gas safety check, inspection and maintenance service to ensure the gas appliance in your system always operates in the most efficient manner possible.

Why a Boiler Service is Important

The annual boiler servicing service is not mandatory but it is very essential to keep your own boiler running and in the best condition. The annual boiler service is also an excellent way to know what boiler repairs are needed and when they should be done.

A few reasons why you should have an annual boiler service include:

Checking for leaks

If the gas engineer finds small leaks in the early stage they will be easy to repair. Usually, the fault can be as small as a washer or seal replacement. But if you leave this leak to drip for a few more weeks, this can cause major damage.

Our gas engineer also checks the gas pressure check flue integrity, gas boilers, gas pipe and valves for leaks so we can take care of our customers. We also check the up-to-date gas safety certificate.

Gas Safety

During the boiler service, our reliable gas engineer can identify gas safety issues that can cause major damage to your property or can be life-threatening.

Always make sure you are installing a carbon monoxide alarm close to the boiler!

Sometimes you can check yourself if it is time the need an annual boiler service. If the gas boiler flame is orange rather than blue it is time to call a gas engineer, who will visually inspect your boiler performance.

Prevent costly breakdowns

To prevent expensive repairs and breakdowns, you must have your boiler regularly serviced. In general, it is recommended that you book a boiler service annually.

If you service your boiler every year, you can avoid breakdowns which sometimes can cost you a fortune.

Keep the manufacturer’s warranty

After fitting the boiler this will come with a 5-12 year parts and labour warranty. As long as it was installed to the manufacturer’s requirements. Also, it is the manufacturer who requires that the boiler is power flushed after the installation, a magnetic filter will be installed and the annual boiler service will be carried out. If you follow all of these steps, you can have up to 10-year free repairs from the manufacturer.

What happens during a boiler service?

The gas engineer will carry out the mandatory boiler service checks. These check includes the boiler’s performance to ensure that it is running efficiently and meets safety standards, analysing the gas supply by regulations, and flushing out any debris or dust from the condensate pipes which may hinder the efficient operation of gas appliances in the system.

Usually, a typical boiler service checklist also includes extra checks:

1. Visual inspection 

The engineer will take off the boiler casing, looking for any signs of damage or corrosion.

Watching the operation and pressure to detect any leaks.

The engineer will also inspect the boiler, electrical connections, valves, gauges, heat exchangers and wiring.

2. System controls and operation

Your system has many controls. A combi boiler will normally have a room thermostat that is controlling the temperature in the rooms, and a programmer which tells the boiler when to heat up.

Our boiler engineers check if you have any problems with these controls and if they are set correctly.

3. Radiator conditions

The engineer will also check that all parts of the system are working correctly as they should such as circulating pumps and radiators. We use a thermal imaging camera to identify any debris in the heating system.

4. Flue safety check

Our engineers will check if the flue is installed and working properly and if any obstructions or blockages can avoid the gases to escape from the boiler. He/she will carry out a flue gas analysis

It is also important, that the flue gases can not enter back to the house, so the flue has to be at least 300mm away from any window or ventilation.

We also check the flue integrity, this means the air intake doesn’t have any holes inside and the air won’t mix with the gases.

Also, the flue needs to have a slope back to the boiler so the condensate pipe can leak back and won’t damage the boiler flue and pipe.

5. Boiler components cleaning

In the second year of the new boiler installation, it is mandatory to do a full boiler service. We call this a full boiler service. This oil boiler service means the heat exchanger will be cleaned, the seal will be changed on the burner and the ignition pins will be cleaned.

A short list of what safety checks we carry out

We will check many different components:

  • Cleaning and inspecting the pilot burner
  • FSD (flame sensing device correct operation, this has to fail safe if there will be no more flame in the boiler)
  • Boiler full operation in heating and hot water mode
  • We check the temperature sensors
  • The minimum ventilation
  • Boiler locations from burning materials
  • Flue terminals and integrity check
  • Cleaning the condensate trap
  • Precharging the expansion vessel
  • Checking the boiler pressure
  • Wiring and connections
  • Safety devices and seals
  • Gas pressures
