If your home relies on oil heating, you know that specialised care is required to keep your system running safely and efficiently. Unlike standard gas systems, oil boilers require precise burner calibration and regular tank inspections to prevent costly leaks and soot buildup.
At Webb Heating Services Ltd, we are fully OFTEC-registered and provide the expert maintenance your oil-fired system needs to survive a Welsh winter.
We provide end-to-end support for all domestic oil-fired appliances, ensuring they operate at peak performance while protecting the environment.
A yearly service is vital for oil boilers. Because oil is a "dirtier" fuel than gas, soot naturally accumulates on the heat exchanger, which can drop your efficiency by up to 10% in just one year.
- What we do: We clean the combustion chamber, replace the burner nozzle (essential for a clean flame), check the flexible oil hoses, and perform a full smoke-box analysis.
- The Benefit: Lower fuel bills, reduced risk of breakdown, and carbon monoxide safety.
If your boiler is locked out or producing "black smoke," it needs immediate professional attention. Our engineers carry specialised diagnostic equipment to fix:
- Faulty Fuel Pumps: Ensuring the correct pressure is reaching the burner.
- Photocell Issues: Cleaning or replacing the "eye" that monitors the flame.
- Ignition Failures: Repairing transformers and electrodes to ensure a clean start every time.
Your fuel tank is as important as the boiler itself. We perform safety checks to identify:
- Water Contamination: Removing condensation from your tank to prevent it from reaching and damaging your boiler.
- Structural Integrity: Checking for "crazing", cracks, or rust that could lead to an environmental spill.
- Filter Replacement: Changing oil filters to ensure only clean fuel enters your system.
In 2026, keeping your oil system running efficiently is key to managing energy costs:
- Don't Run Dry: Letting your tank run empty can pull sludge and debris from the bottom of the tank into your boiler's pump.
- Monitor Your Tank: Check your oil levels monthly and look for any signs of weeping or dampness around the base.
- Summer Servicing: Beat the winter rush! Booking your oil service in the summer ensures you are ready the moment the temperature drops.
Frequently Asked Questions
Does an oil boiler need a different engineer than a gas boiler?
Yes. While some engineers do both, your technician must be OFTEC registered to legally and safely work on oil-fired appliances.
How often should an oil tank be inspected?
We recommend a visual inspection every time we service your boiler, with a detailed check of the base and supports every year.
Is it worth upgrading an old oil boiler?
Modern condensing oil boilers are significantly more efficient. Moving from an old non-condensing unit can save you up to 30% on your annual kerosene bill.
