What Roy Checks During an Oil Boiler Service

Annual Servicing for Off-Grid Heating
Annual servicing is especially useful for rural and off-grid homes that depend on oil heating through the colder months. A service may include inspection of the appliance, burner, flue, ventilation, oil filters, nozzles, pump, ignition components and flexible oil lines, depending on the boiler and manufacturer instructions.
Always follow your boiler manufacturer’s service schedule and warranty requirements.
Signs Your Oil Boiler Needs Attention
Warning signs include difficult starting, repeated lockout, unusual smells or noises, soot, reduced efficiency, uneven heating, oil-line wear or signs of an oil leak. Stop using the appliance and seek advice if you suspect a fuel leak or unsafe operation.
If the boiler already has a fault, see oil boiler repairs and breakdown diagnosis. If your appliance is older or inefficient, read about oil boiler replacement.

Frequently Asked Questions
How often should an oil boiler be serviced?
Most domestic oil boilers should be serviced once a year, or as required by the manufacturer.
Will the oil boiler nozzle always be replaced?
Roy will inspect the burner nozzle and replace it where required rather than promise unnecessary parts. Filters and flexible oil lines are also checked for condition and suitability.
Can servicing improve efficiency?
Correct cleaning, combustion checks and adjustment can help an oil boiler run more efficiently, but the result depends on the boiler condition, system design and any underlying faults.
