The presence of a remote control in the design of the heater.
In this case, the
remote control means, in fact, any controller made separately from the heater itself. Most often, such a “remote” is installed on a wire that connects the device to the cigarette lighter, or even on a plug: this design is very inexpensive, while it is quite affordable and functional. But the heating control buttons, which are equipped with
built -in models (see "Type"), are not considered a remote control.
Power consumption of the device. When choosing, this parameter often has an exclusively reference value: the energy consumption of heating systems is not so high as to cause problems when connected to the on-board network, and the specific heater power is selected by the manufacturer in such a way that the device is able to effectively perform its functions.
