öljynlämmittimen

An oil heater, known in Finnish as an öljynlämmitin, is a device that heats a space using oil as its fuel source. These heaters typically consist of a fuel tank, a burner, a heat exchanger, and a mechanism for distributing the heated air. The oil, usually kerosene or heating oil, is drawn from the tank to the burner where it is atomized and ignited. The resulting flame heats the heat exchanger, which in turn warms the surrounding air. This heated air is then circulated into the room, providing warmth.

Oil heaters are often portable and do not require a chimney or vent, making them suitable for temporary heating needs in garages, workshops, or construction sites. They can be electric ignition or pilot light models. Some models are designed for indoor use with appropriate ventilation, while others are strictly for outdoor or well-ventilated areas due to the risk of carbon monoxide poisoning. Safety features commonly include tip-over switches that shut off the heater if it is accidentally knocked over, and safety grilles to prevent burns. Maintenance usually involves cleaning the burner and replacing the wick if applicable. The efficiency of an oil heater depends on factors such as the type of oil used and the design of the unit.
