How Oil Boilers work
Oil central heating works similarly to gas systems. A boiler burns heating oil to heat water, which is then circulated through your radiators and taps. You’ll need a separate oil storage tank, typically located outside the property, which is filled periodically by a fuel supplier..

Step-by-Step Oil Central heating Process
1. Initial Inspection
Your engineer will begin with a full visual inspection of the oil boiler and surrounding area. They’ll check for signs of leaks, corrosion, or external damage. The oil tank (if visible) is inspected for wear, contamination, or faults, and the boiler’s installation is reviewed to ensure it’s safely positioned with proper ventilation.
2. Removal of Boiler Casing
Next, the boiler’s front casing is carefully removed to access critical internal components. This allows the engineer to inspect the burner, heat exchanger, flue system, and oil filter for wear, blockage, or early signs of failure.
3. Cleaning the Key Components
The engineer thoroughly cleans the burner to support optimal combustion and avoid soot build-up. The heat exchanger is cleaned to remove deposits that can affect efficiency. The oil filter is either cleaned or replaced, and the flue system is checked and cleared of any obstructions.
4. Burner & Combustion Test
The burner is tested to confirm reliable operation, and a flue gas analyser is used to check for safe levels of CO and CO₂. The oil pump pressure is also tested to ensure it matches manufacturer specifications, which is crucial for proper heating performance.
5. Check Oil Supply and Tank
Your engineer will inspect the oil supply lines for any leaks or cracks and assess the oil level in the tank. They’ll also check for water contamination or sediment build-up, which can reduce system performance. Venting on the oil tank is also verified.
6. Test and Adjust Boiler Settings
The boiler’s system pressure is tested and adjusted to the correct range (typically 1–1.5 bar). The thermostat is calibrated to ensure accurate readings, and the boiler is run under typical heating and hot water loads to confirm stable operation.
7. Safety Checks
Essential safety features are checked, including the pressure relief valve, expansion vessel (if present), and the oil burner control settings. This ensures the system operates safely and won’t be at risk of pressure-related faults or overheating.
8. Completion of Service Documentation
Once testing is complete, your engineer fills out a detailed service log (usually found in the boiler manual). Any required repairs or recommendations will be noted, and a service certificate may be issued for warranty or insurance compliance.
9. Reassembly and Final Testing
The final step is to reassemble the boiler casing and run one last test. The engineer checks for leaks, verifies the boiler runs smoothly, and ensures the heating system is functioning efficiently before leaving your property.
