lisälämmitin

A lisälämmitin, which translates to auxiliary heater or booster heater, is a device designed to supplement the main heating system in a vehicle. These heaters are typically installed in passenger cars, especially in colder climates, to improve passenger comfort and reduce the strain on the primary engine heating system. Their primary function is to provide heat to the cabin more quickly after the engine has started, or to maintain a comfortable temperature when the engine is running at low load or idling.

There are several types of lisälämmitin. Some are electrically powered, drawing energy from the vehicle's battery. These are often simpler in design and installation but can consume significant battery power. Others are fuel-powered, burning a small amount of the vehicle's fuel (like diesel or gasoline) to generate heat. These are generally more efficient in terms of heat output and do not unduly drain the battery. Some advanced systems can also be programmed to pre-heat the vehicle's interior before the driver even gets in.

The integration of a lisälämmitin can lead to reduced fuel consumption in some scenarios, as the main engine does not need to work as hard to warm up the cabin. It also contributes to passenger well-being, particularly during cold weather, by ensuring a comfortable environment from the outset of a journey. The operation and control of these heaters vary by model and manufacturer, often integrated into the vehicle's climate control system.
