1. A portable heater comprising:
a ceramic substrate with a heating element configured to define a field of direct radiation;
a heat reflector with a concave reflective surface configured to define a field of reflective radiation, the heat reflector having a peripheral rim;
a grill cover mounted on the peripheral rim of the heat reflector, and
a line pipe with a wire conduit configured to energize the heating element passes, the line pipe extending outside of the field of direct radiation,
wherein the ceramic substrate is mounted on an interior side of the grill cover with the heating element facing the concave reflective surface such that the field of direct radiation onto the concave reflective surface is unobstructed.
