Oil Boilers

What you need to know about your oil heating appliance.

An oil boiler should produce very little emission. Signs that it may need tending to:

• Black smoke or a build-up of soot - this prevents the boiler from burning oil efficiently.
• A yellow or brown staining around or on the boiler.
• A pilot light that frequently blows out.
• Increased condensation inside windows.
• A yellow rather than blue flame (apart from flueless fires).

An Oil Boiler Service will:

• Clean the burner/injector(s)
• Clean the pilot/injector
• Clean the flue-ways, including the draught diverter & heat exchanger
• Clean & adjust the ignition components
• Clean flame supervision components
• Clean, lubricate & adjust controls
• Check all disturbed connections
• Check all boiler seals & joints
• Check there are no obvious signs of damage to the wiring
• Re-set the burner operating pressure to that on the data label/plate
• Test open flued boilers for spillage
• Re-check the flame supervision device operation
