A portable heater that includes 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, a grill cover mounted on the heat reflector, where 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.

An outdoor-use heating mat includes a mat body, a water container, a substance container, and a first circulating pump. The water container is disposed in the mat body. The water container has a first inlet and a first outlet. The substance container is configured to hold a substance that can chemically react with water and release thermal energy. The substance container has a second inlet, a second outlet, and a normally closed feed port. Two ends of the first circulating pump are in communication with the first outlet and the second inlet, respectively. The second outlet is in communication with the first inlet. The outdoor-use heating mat can be heated, easy to carry.

A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.
