Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
87 words
An electric heating system for at least one confined space of a building provided with an electric current source connectable therewith, said heating system consisting of thin heating layers comprising electrically conductive heating wires and interposed insulating wires, said heating layers distributed covering the entire boundary of said space so that each part of said boundary radiates the same amount of heat radiation in unit time per unit surface area, said amount of heat being controlled by the amount of electrical energy delivered to said heating system.
Claim 2
Dependent Claim
87 words
An electric heating system for at least one confined space of a building provided with an electric current source connectable therewith, said heating system consisting of thin heating layers comprising electrically conductive heating wires and interposed insulating wires, said heating layers distributed covering the entire boundary of said space so that each part of said boundary radiates the same amount of heat radiation in unit time per unit surface area, said amount of heat being controlled by the amount of electrical energy delivered to said heating system.
Claim 3
Dependent Claim
77 words
An electric heating system according to claim 1, characterized in that said thin heating layers comprise parallel strips of electrically conductive heating weft threads, said strips being separated from one another by strips of electrically insulating weft threads, the electrically conductive heating wires of each strip being connected at each of their ends with a strip of electrically conductive warp threads, warp threads of electrically insulating material being provided between said strips of electrically conductive warp threads.
Claim 4
Dependent Claim
40 words
An electrical heating system according to claim 2, wherein the boundary is provided with at least one window, characterized in that at least one said heating layer is provided at a small distance from and in front of said window.
Claim 5
Dependent Claim
19 words
An electric heating system according to claim 2 wherein the electrically insulating weft threads are of heat conductive material.
