Patent ID: 7326881

Claim:
A floor heating system, comprising: a sub-floor; a plurality of fasteners; a first heater conductor assembly including: a first resistive conductor having a first length, and first and second ends said first resistive conductor being of a first gauge; and two low resistance conductors being respectively connected to each of said first and second ends, said low resistant conductors being of a second gauge, said first gauge being a larger numeric value than said second gauge; and a second heater conductor assembly including: a second resistive conductor having a second length, and first and second ends, said second resistive conductor being of said first gauge; and two low resistance conductors being respectively connected to each of said first and second ends of said second resistive conductor, said low resistant conductors being of said second gauge, said low resistance conductor that is connected to said first end of said first resistive conductor being connected in a serial fashion to said low resistance conductor that is connected to said first end of said second resistive conductor, said first length being approximately a first integer multiple of said second length, said first resistive conductor and said second resistive conductor having substantially the same resistivity per unit of length, said plurality of fasteners connecting said first heater conductor assembly and said second heater conductor assembly to said sub-floor, said first integer being larger than 1.
