Spare parts for gas and oil burners and boilers: gas valves, nozzles, ignition electrodes and transformers, pressure switches, flame detectors, fuel pumps, servomotors and burner control boxes.

Choosing and fitting

Oil nozzles are selected to match the specific model and series of the heating unit. Verify the exact boiler or burner model number against the compatible models list before ordering. Ensure the mounting interface and physical dimensions match your equipment. Replacement follows the manufacturer's guidance for your unit's vintage and voltage specification if applicable.

Signs of failure

Worn or damaged oil nozzles typically result in uneven heating, with hot spots in some areas and insufficient heat in others. You may notice the fan operating inconsistently or the burner cycling more frequently than normal. A blocked or degraded nozzle can reduce overall system efficiency and increase fuel consumption. If heat distribution becomes noticeably uneven or the equipment shows signs of struggling to maintain temperature, the nozzle should be inspected and replaced if necessary.
