1968 – 1979 VW 1600 Transporter Supplementary Heater

For markets where extremely low temperatures are frequently encountered, the heat exchanger system is not adequate to maintain the vehicle interior at an acceptable temperature. In these case a separate heater unit is installed at the rear in the engine compartment. These units consist of a fan/combustion unit which uses petrol as a fuel. There is a special combustion chamber and the petrol is ignited by spark and glow plugs. Hot air is blown into the regular system distribution. The combusted gases are exhausted under the vehicle.
