The fact that an electrical car heating system gives lower fuel consumption and reduced emissions of harmful waste-gases from the first driven meter is well known. But not at least as important is that such systems also contribute to increase traffic safety: A warm and comfortable driver is a much safer driver than a frozen and not comfortable one.

Everybody knows that cold starts wear disproportionate on an engine, but there are also research showing that you are more exposed to neck stiffness and problems with your back if you often starts the day in an ice-cold car. At the same time you are not as concentrated and a less safe driver, because so much of your attention is concerned about freezing. DEFAs car heating system is up to date when it comes to today’s increasing demand for comfort. The system secures the car owner a warm interior with clean windows, pre-heated and easy started engine and reduced wear on both car and body. You also get top charged battery, with minimum waste of electricity. Other positive effects are that you also save fuel at the same time as the harmful waste-gas emissions are reduced.
A complete car heating system includes a patented Mini Plug inlet, electronic control unit, interior heater and an electronic battery charger, in addition to the engine heater itself and installation equipment.
By using the electronic battery charger, you are secured a top charged battery and a safe start throughout the whole winter. The charger is secured against over- charging and switches automatically to maintenance-charging when the battery is fully charged.
By using the control unit with automatic connection guided by the outside temperature, the system itself controls the process in an optimal way. Regardless the outside temperature you are insured a correct pre-heating of the car, at the same time as you are guaranteed lowest possible energy consumption.
The control unit shows the outside temperature, battery voltage / charging voltage and has a built-in 0-condition warning which warns about the risk for slippery road way by temperatures round zero.
