The winter package include a Thermo 50. This unit is assembled near engine and part of the coolant circuit. It is a small diesel burner (heater) that warm up engine by heating the engine coolant before starting (anywhere). Rather than plugging the engine (electrical heating), the burner is fed with diesel fuel directly from fuel tank. The engine is warmed up about 15-30 mins depending on outside temperature. This is a very useful option (see picture).
