FIELD: construction engineering. SUBSTANCE: heated floor construction has floor base, multiplicity of components made of sheet material, at least one electric heating cable, and device for regulating dissipation of cable producing heat. Heating cable is enclosed in at least one passage arranged between different sheet material components. Passage or passages are made of width which suits maximal possible diameter of electric heating cable. Width of sheet material components corresponds to cable spacing in the form of center-to-center distance minus maximal diameter of heating cable. Corners of sheet material components over those edges at which heating cable changes its direction are bevelled or cut off. Passage or passages are restricted at bottom by floor base. Sheet material components are placed on and fastened to floor base and have thickness which corresponds to maximal diameter of heating cable. Surface material is located on upper surface of sheet material components. EFFECT: higher efficiency. 15 cl, 12 dwg
