The cabin heater is equipped with PTC technology that regulates power based on prevailing temperature conditions. As the temperature of the compartment increases, the power decreases and thus the energy consumption. The cabin heater is equipped with both thermal and electrical fuses that protect against overheating. If you happen to cover the heater with a jacket, the fuse blows and the heater will turn off.
Tests show that the heater provides quick heating and even temperature distribution throughout the cabin. This reduces the connection time and hence the power consumption.
The cabin heater can either be mounted stationarily on the vehicle center console or attached to a rack mounted with Velcro strap (accessory). The cabin heaters are so small and light that they can stay mounted all year round. In those cases where permanent heating of the passenger compartment heater is not possible, there is a separate stand that is placed underneath the vehicle carpet and fastened with Velcro strap.
