Abstract
A combination including a heater, a first connection device and a second connection device. The heater has heating elements or resistors; and a heater connector with electric heater conductors connected to the electric heating elements. The first and second connection devices have first and second output connectors with conductors for connection to the conductors of the heater connector and first and second input connector for connection to first and second standard connectors of first and second power sources with first and second voltage levels. The electric conductors of the first output connector have a first connection configuration in the first connection device and the electric conductors of the second output connector have a second connection configuration in the second connection device different to the first connection configuration. At least two heating elements are so connected to the first electric conductors as to be powered: in the first connection configuration via the first connection device to the first power source; and in the second connection configuration via the second connection device to the second power source.
