A molded polymer composite heater is shown. The use of transfer molding and compression molding allows for the use of thermoset polymers containing very high levels of reinforcement fillers. These improved materials, in turn create a heater with thermophysical properties superior to the prior art, including higher heat flux levels, thermal conductivity, impact resistance, and maintenance of mechanical properties at high temperatures (.about.>300.degree. F.). The present invention also allows for wide variety of geometric configurations and the possibility to insert temperature sensors directly in hot zones of the heater.
