Are you sure? In the Lupo 3L the heater is after heat exchanger:In reality the electric auxiliary heater does help warm up the engine quicker but only slightly. This is due to the positioning of the electric heater below the heater matrix in the cabin. The air is blown by the fan into the cabin and also rises into the matrix putting some warmth into the coolant sytem however marginal.
