An In-Depth Look at an Annual Oil Boiler Service by an OFTEC Engineer: What's Inspected and Cleaned

Updated: Aug 26, 2023

Regular maintenance is crucial to ensure the optimal performance and longevity of your oil boiler. When it comes to an annual oil boiler service, entrusting the job to an OFTEC (Oil Firing Technical Association) engineer ensures that the service is carried out by a trained professional who adheres to industry standards. In this blog post, we will provide an overview of the essential inspections and cleaning tasks performed by an OFTEC engineer during an annual oil boiler service, highlighting the importance of each step.

Visual Inspection

The service begins with a thorough visual inspection of the oil tank, oil supply, oil boiler and its components. The OFTEC engineer examines the tank and boiler for any signs of damage, corrosion, leaks, or wear. They check the integrity of seals, gaskets, and pipework. This visual inspection helps identify potential issues that may affect the boiler's performance or safety.

Combustion Chamber Cleaning

The combustion chamber, where the fuel is burned, is a critical component of an oil boiler. During the annual service, the OFTEC engineer cleans the combustion chamber to remove any soot, debris, or residue that may have accumulated over time. This cleaning ensures optimal combustion efficiency and reduces the risk of blockages or incomplete combustion.

Flue Inspection and Cleaning

The flue system plays a vital role in safely venting combustion gases out of the boiler and the property. The OFTEC engineer inspects the flue for any obstructions, damage, or leaks. They check the flue's stability, ensuring it is securely fitted and properly sealed. If necessary, the engineer will clean the flue to remove any soot, debris, or blockages that could impede the proper functioning of the boiler.

Burner Maintenance

The burner is responsible for igniting and combusting the fuel in the oil boiler. During the service, the OFTEC engineer inspects and cleans the burner components. They check the condition of the burner nozzle, which atomizes the fuel for efficient combustion. If needed, they will clean or replace the nozzle. The engineer also ensures that the burner's ignition system is functioning correctly, providing reliable ignition.

Fuel System Inspection

The OFTEC engineer examines the oil supply system, including the fuel tank, filters, and fuel lines. They check for any signs of leaks, damage, or blockages. The fuel filters may be replaced or cleaned to ensure that the oil flowing into the boiler is clean and free from contaminants that could impact performance.

Controls and Safety Devices

During the service, the OFTEC engineer tests and inspects the boiler's controls and safety devices. This includes checking the operation of the thermostat, pressure relief valve, pressure gauge, and other safety mechanisms. Any faulty components are identified and replaced to ensure the boiler's safe operation.

An annual oil boiler service performed by AMC Oil Boiler Services involves a comprehensive inspection and cleaning process to guarantee the optimal performance, efficiency, and safety of your heating system. From visual inspections and combustion chamber cleaning to flue inspections, burner maintenance, and fuel system checks, every aspect of the boiler is carefully examined. Entrusting this task to an OFTEC engineer ensures that the service is conducted by a trained professional who follows industry standards. By scheduling an annual oil boiler service, you can have peace of mind knowing that your heating system is well-maintained and operating at its best.
