Heat transfer apparatus, whether in panel or tubular form, comprises bimetallic laminations, at least one of the metals being ferromagnetic. A temperature differential causes thermoelectric current circulation (in effect, a d.c. eddy-current) within each lamination which develops a magnetizing H-field. A transverse electric potential may also be used to enhance thermoelectric activity across a bimetallic junction. The ferromagnetic B-field enhancement develops in turn a circulating diamagnetic reaction current which augments the thermoelectric activity and causes an overriding thermal feedback and bistable direction-of-heat-flow operation. Control involves the priming action of an applied electric and/or magnetic field or preheating by electrical resistors in the heat sinks. Application in a thermally powered electric transformer generator is described.
