<p>MODULAR ELECTRICAL HEATER A heater comprising a pair of flexible elongate parallel conductors which are connectable to a power supply, and a plurality of rigid heating modules connected in parallel with each other between the conductors. Each of the heating modules comprises a resistive heating component which has been deposited on the substrate and which generates heat when the conductors are connected to a suitable power supply. The heating component may have a positive temperature coefficient of resistance or substantially zero temperature coefficient of resistance.</p> |
