FIELD: heating. ^ SUBSTANCE: warmth-keeping floor includes electric heating system containing heating sections with electric current leads. At that, in heating system of warmth-keeping floor the heating sections are made of interconnecting tubes the cavity of which is filled with electrolyte, for example, water solution of sodium chloride. At that, tubes are made from material with temperature linear expansion coefficient which is more than that of electrolyte, for example, from polypropylene, and current leads of heating sections are made from graphite and installed symmetrically into holes of side tubes of each section and are connected with parallel current-conducting buses. ^ EFFECT: simplifying the manufacturing procedure of warmth-keeping floor, reducing the cost, roving reliability and operating safety. ^ 1 dwg |
