Oil burners for hot water and steam boilers provide the combustion to heat water in the boiler until it's hot enough to be sent to a radiator, baseboard, or heating coil.

These ignition transformers ignite the oil in hot water and steam boiler burners. They transform the incoming electrical power to a level high enough to ignite the oil droplets in the burner, producing a flame in the heating chamber that allows the water in the boiler to heat up.

Oil burner pumps for hot water and steam boilers pump oil from the fuel tank to the oil burner, where it's burned to heat the water in the boiler.

Nozzles for oil burners atomize the fuel oil so it can be ignited. They mix the oil with air and create a spray pattern and transport it to the spark produced by the ignitor.

Ignitors for oil burners use less power than ignition transformers, making them more efficient. They also perform better with cold oil or delayed spark conditions, have higher output currents and peak voltages, and produce a spark intensity that can be less sensitive to line voltage fluctuations. Ignitors create a spark next to the nozzle in the burner. The nozzle compresses air and oil and transports it to the spark, where it's ignited to produce heat.
