Abstract

Conventional electrical heaters, tube- or plate-like, change electric energy into thermal energy and transmit it from wires or some other materials supported on an insulation basement to a heat exchanger (in many cases also through insulating air). Tube-like heat exchangers are sometimes immersed into liquid as electrical tube-like heaters around which the liquid may circulate. The basic problem with all these known heaters is the loss of thermal energy which occurs when thermal energy on its way to warm up a medium passes materials with bad thermal conductive properties. This problem is avoided with the invention.
