What Happens During a Boiler Service?

A boiler service is an essential part of maintaining your central heating system. It’s usually a good idea to get one done every year to keep your gas appliances in working order and to prevent potential problems down the line.

A faulty boiler can be dangerous for your home and family, especially if it releases carbon monoxide (CO). This is a clear, odourless gas that can cause poisoning and even death. Regular boiler services can help to identify and fix any issues before they lead to a CO leak.

During a boiler service, the Gas Safe Registered engineer will check the internal workings of the boiler. This involves removing the casing to see the burner, heat exchanger, and other important components. They will also inspect the flue terminals to ensure that they are safely fitted and that any dangerous gases are discharging effectively.

They will check the air-to-fuel ratio, which is critical for fuel efficiency. If there is too much or too little air, then the combustion process won’t be as efficient, which can lead to soot, ash, and carbon monoxide.

Finally, they will check the gas pressure of the boiler, which is crucial for ensuring that your taps and radiators have enough pressure to work properly. This can be affected by external factors, such as low water pressure or a leak in the gas pipe. They may also take a reading from the stack temperature gauge, which is used to measure the overall performance of the boiler and detect any issues such as corrosion or soot build-up. gas boiler service
