Here we deal with a few of the most frequently asked questions about Calix car heating systems.
How will I know which Calix products best suit my car?

Engine pre-heaters, MKMS cable sets and GL branching cable kits are the only items that cannot be used for all makes of car. Other Calix accessories are suitable for most makes of car currently on the market. To choose the correct product for your vehicle, click on 'Product search' in the menu to the left, or contact one of our retailers.
For how long does the engine pre-heater need to be connected before the car can be used?

You will need to adjust the connection time depending on the outdoor temperature. Recommended times are:

At +10°C approx. 1h
At 0°C approx. 1h
At -10°C approx. 2h
At -20°C approx. 3h

Calix also produces various models of timer for controlling connection times. For additional information see our products in the menu to the left.
My parking space has a socket with a 'pulsating' voltage, i.e. the voltage connects at various intervals depending on the outdoor temperature. Is this still suitable?

No, this is no good. Engine pre-heaters are not designed to work with a 'pulsating' voltage, as this results in an abnormally short service life. The product guarantee is invalidated if pre-heaters are connected to a 'pulsating' voltage.
