Sähkölohkolämmitin

Sähkölohkolämmitin, often referred to as an engine block heater, is an electrical device used to preheat the engine block of a vehicle, typically in cold climates. Its primary function is to warm the engine coolant, which then circulates and heats the engine components. This preheating offers several advantages, including easier engine starting in low temperatures, reduced engine wear during the initial stages of operation, and faster cabin heating.

The device typically consists of an electric heating element that is immersed in the engine's coolant system or bolted directly to the engine block. It is powered by a standard household electrical outlet, usually via an extension cord that runs from the vehicle to a power source. Many vehicles equipped with sähkölohkolämmitin have a socket located on the front grille or bumper for easy connection.

The use of a sähkölohkolämmitin is most beneficial in regions with significant winter temperatures. By ensuring the engine oil remains less viscous and the metal parts are expanded slightly, it reduces the strain on the starter motor and the engine's internal components during cold starts. This leads to improved fuel efficiency in the initial minutes of driving and a more comfortable driving experience due to the quicker availability of cabin heat. Proper installation and regular maintenance are essential for safe and effective operation.
