What Happens When a Boiler is Serviced?

Imagine going through an extremely cold winter day and having your heating system give up on you or your boiler system failing just when you need it the most. Fortunately, you can prevent this incident from happening to yourself by scheduling an annual boiler service.

What is a boiler service?

boiler service can help ensure your boiler and central heating system are running as smoothly and efficiently as possible. The service would mostly take less than an hour, but may go up in time depending on the type of appliance.

During a boiler service, a professional engineer will follow a comprehensive boiler service checklist to make sure everything has been checked and is working well. Booking an appointment can give you peace of mind that your boiler is as safe and working well without the risk of suddenly failing on you

What Does a Boiler Service Session Involve?

Visual inspection

The engineer will visually inspect the boiler, clean and adjust its components as required, look out for any danger or faulty signs, and also signs of damage. The engineer will also identify any points of distress and have it looked at immediately.

Operation and control
Your boiler has a number of controls and safety devices that will be tested for correct operation. An engineer will check that all of the boiler functions are working correctly, should they be required.

Flue and combustion releases

The engineer will then check the construction, termination and route of the flue. This is the pipe from your boiler that goes to the outside of your house. This is to make sure there are no obstructions in the flue tunnels and that it is fitted securely.

Cleaning the main boiler components

During a boiler service, the engineer will remove, inspect and clean the main components in the boiler to ensure they are fit for purpose and have no noticeable defects. This will include the main burner, heat exchanger, flue ways, and ignition pins.

The boiler checklist

The engineer will have a checklist of his own when inspecting the boiler for service. Here’s what that checklist looks like.

• Flame sense device and whether it operates correctly
• Pilot burner and any cables and probes
• High-limit thermostat
• Boiler operation
• Provision of adequate ventilation
• Flue effectiveness
• Heating controls
• Electrical wiring connections
• Location of the boiler and nearby combustible materials
• Gas and pressure flow
• Safety devices
• Seals

Conduct a record

The engineer will make a record of the necessary observations based on his checklist. This will include a record of the boiler pressure or heat input. As the homeowner, you will be given this record for your safekeeping and can refer to it for inspections or when problems arise.

Ensure the boiler is ready for use

At the end of a boiler service, the engineer will make sure the boiler is working well, and that it is safe and ready for use. Any controls or settings that were changed during the service will be either put back to your previous settings or left as is, so that you can easily adjust the settings yourself according to your preferences.
