1. A heating arrangement comprising:a positive temperature coefficient (PTC) heater;
a resistor electrically in series with the PTC heater sized and configured to limit current through the PTC heater and the resistor below a selected value;
wherein said PTC heater is utilized as a floor panel;
wherein said PTC heater has a resistance multiplier that is relatively static at lower temperatures, but increases by a factor of at least 2 across a 10° C. temperature increase as a target temperature is approached; and
wherein said PTC heater has a surface area, and said resistor is a resistance heating element which is within said surface area.
