What is included in an oil boiler service?

Oil Boiler Service

An OFTEC oil boiler service typically involves a comprehensive inspection and maintenance process to ensure the safe and efficient operation of the boiler. Here’s a breakdown of what’s typically involved:

Visual Inspection: The technician will visually inspect the boiler and its surrounding components for any signs of damage, leaks, or corrosion.

Cleaning: The technician will clean various components of the boiler, including the burner, heat exchanger, flue ways, and combustion chamber, to remove any buildup of soot, debris, or blockages.

Checking Oil Supply: The technician will check the oil supply system, including the oil tank, filter, and fuel line, to ensure that there are no leaks or blockages that could affect the boiler’s performance.

Testing Controls: The technician will test the boiler’s controls and safety devices, such as the thermostat, pressure relief valve, and flame supervision device, to ensure they are functioning correctly.

Combustion Analysis: The technician will perform a combustion analysis to measure the efficiency of the boiler’s combustion process and adjust the burner settings if necessary to optimize efficiency and minimize emissions.

Inspecting Seals and Gaskets: The technician will inspect the seals and gaskets on the boiler and replace any that are damaged or worn to prevent leaks and ensure proper sealing.

Checking Flue: The technician will inspect the flue system to ensure it is properly installed and free from obstructions, which could pose a safety hazard or affect the boiler’s performance.

Testing Pressure and Temperature: The technician will test the boiler’s operating pressure and temperature settings to ensure they are within the manufacturer’s recommended range.

Providing Recommendations: Based on the inspection findings, the technician may provide recommendations for any necessary repairs or upgrades to improve the boiler’s performance, efficiency, or safety.

    Frequently asked questions..

    It’s generally recommended to have your oil boiler serviced annually to ensure it’s operating efficiently and safely. Regular servicing can help prevent breakdowns, identify any potential issues early, and maintain optimal performance. Additionally, some manufacturers may specify service intervals in their warranties, so it’s essential to check the manufacturer’s recommendations for your specific boiler model.

    An oil boiler service can vary per company and location. Our oil boiler service costs £70+VAT which includes the replacement of the oil nozzle. Whilst it may be tempting to go for the cheapest service, it is important to ensure the service is done properly which can reduce breakdowns and improve safety/efficiency. 

    Safety: One of the most important reasons to service your oil boiler is for the safety of you and your family. Boilers that aren’t properly maintained can be dangerous, with the risk of carbon monoxide leaks and other hazards such as oil pollution. By having your oil boiler serviced regularly, you can ensure that it is running safely.

    Efficiency: An oil boiler that isn’t running at its best can be less efficient, which means it’s working harder and using more fuel to heat your home. This not only drives up your energy bills, but it also means that you’re releasing more carbon dioxide into the atmosphere. By having your oil boiler serviced regularly, you can keep it running at its most efficient, which can save you money on your energy bills and help to reduce your carbon footprint.

    Longevity: Like any machine, your oil boiler will eventually wear out. However, with proper maintenance, you can extend its lifespan and get more value for your money. By having your oil boiler serviced regularly, you can catch small issues before they become big problems, helping to keep your boiler running smoothly for years to come.

    Peace of mind: Finally, regular boiler servicing can give you peace of mind, knowing that your boiler is running safely and efficiently. This can be especially important during the colder months, when you rely on your boiler to keep your home warm and cosy.

    An oil boiler service can depend on the age and condition of the oil boiler. However, on average we would allow 1 hour per service. 

    Oil nozzles are important in oil boilers because they turn fuel oil into a fine mist for efficient burning. They help the boiler run smoothly and use fuel effectively. Nozzles also affect flame size and stability, which is crucial for reliable operation. Choosing the right size and type of nozzle is key for optimal performance. Regular maintenance is necessary to keep them working well and prevent problems like clogs or wear. In short, oil nozzles are vital for efficient, reliable, and long-lasting operation of oil boilers.

    A flue gas analysis is a test that checks the gases coming out of a boiler. It looks at things like temperature, oxygen levels, and pollutants to see how well the burning process is working and if it’s polluting too much. This helps ensure safety, efficiency, and environmental compliance.


    Yes, we can send you a digital copy of a flue gas analysis as soon as it is complete. 

    If you neglect to get your oil boiler serviced regularly, several potential issues could arise:

    1. Reduced Efficiency: Without regular servicing, your boiler may start to operate less efficiently, leading to higher fuel consumption and increased energy costs.

    2. Increased Risk of Breakdowns: Regular servicing helps identify and address minor issues before they escalate into major problems. Without servicing, these issues can accumulate and eventually lead to breakdowns, leaving you without heating or hot water when you need it most.

    3. Safety Hazards: A poorly maintained oil boiler can pose safety risks, including the potential for carbon monoxide leaks or fuel leaks, which can be harmful to your health or even life-threatening.

    4. Shortened Lifespan: Neglecting maintenance can cause excessive wear and tear on the boiler’s components, leading to premature failure and the need for costly repairs or replacement.

    5. Voided Warranty: Many boiler manufacturers require regular servicing to maintain the warranty’s validity. Neglecting servicing could void your warranty, leaving you responsible for any repair costs.

    Overall, regular servicing is essential for ensuring the efficient, safe, and reliable operation of your oil boiler while maximizing its lifespan and minimizing the risk of unexpected breakdowns or safety hazards.
