Three�heater�coils
The�maximum�electrical�power�of�the�electric�heating�is�5.5 kW�(280 V�x�20 A).�The�electric�heating�is
done�by�three�heater�coils,�each�with�a�power�of�about�0.75 kW,�1.5 kW�and�2.25 kW.�The�switching
of�the�heater�coils�(individually�or�together)�is�effected�within�the�electric�heating�using�an�electronic
switch�(Power�MOSFET).
