Electric-induction boiler has body with installed in parallel metal short-circuit heating pipes, heat insulation installed at the inner surface of pipes, magnetic conductor with core as closed rods with windings installed inside the pipes with gap with respect to heat insulation with formation of air channels. Short-circuit heating pipe is made of two layers. The inner layer is made of mechanically strong non-ferromagnetic metal, and the outer û of non-ferromagnetic metal with high electric conductivity.
