What Is Included In A Boiler Service Check

Most homeowners know that an annual boiler service is recommended, but not everyone is sure what actually happens during the check. A professional service is more than just a quick look at your boiler, it’s a thorough inspection designed to keep your heating system safe, efficient, and reliable. By understanding what’s included in a boiler service check, you’ll have peace of mind knowing your home is well taken care of.

A Closer Look at a Professional Boiler Service

When a Gas Safe registered engineer carries out a boiler service, they follow a structured process to ensure your system is working correctly and safely. This involves checking internal and external components, testing performance, and identifying any potential issues before they turn into costly repairs.

Visual Inspection of the Boiler and Pipework

The service starts with a full visual check. The engineer will look over your boiler and connected pipework to spot any obvious signs of wear, corrosion, or leaks. They also check the position of the boiler to ensure it’s installed safely and in line with regulations.

Safety Checks and Gas Pressure Testing

Safety is the top priority. Your engineer will measure the gas pressure and flow to confirm that the boiler is burning fuel efficiently. They will also check the flue and ventilation to make sure harmful gases are being expelled correctly. This step is crucial for reducing the risk of carbon monoxide leaks.

Cleaning Internal Components

Over time, soot, dirt, and limescale can build up inside your boiler, reducing efficiency. During a service, the engineer may clean key parts such as the heat exchanger, burner, and electrodes. A clean system not only runs more efficiently but can also extend the lifespan of your boiler.

Testing Boiler Controls and Safety Devices

The engineer will test the boiler’s controls, thermostat, and safety devices to make sure they are working as they should. This ensures your heating system responds correctly when switched on and that built-in safety mechanisms, such as pressure relief valves, are functioning.

Identifying Wear and Tear

While some problems may not be visible to you, an experienced engineer can spot early signs of damage. Small issues like worn seals or minor leaks can be dealt with quickly during a service check, preventing breakdowns in the future.

Service Record and Recommendations

Once the service is complete, you’ll receive a record of the checks carried out. The engineer may also provide advice on any repairs or improvements that would benefit your system. Keeping this record up to date is especially important for maintaining your warranty.

Benefits of a Regular Boiler Service

Having your boiler serviced yearly not only keeps it safe but also ensures it runs more efficiently, saving money on energy bills. Regular servicing can also extend the life of your boiler, helping you avoid the expense of a replacement before it’s really needed.
