US6621983B2 — Floor heating device with self-regulating cable

Claim 1

Independent Claim 100 words

An electrically heated floor, comprising: an electric heating cable extending underneath a floor surface to be heated; and pre-assembled panels, each of said pre-assembled panels including a continuous rigid metal panel formed with channels and fitted on a reverse side with an insulating panel in a sandwich structure in such a manner that the channels of the continuous rigid metal panel partially penetrate into the material of the insulating panel, wherein: the assembled panels are deposited on a support below the floor surface; the heating cable is arranged inside said channels; and the heating cable is a self-regulating heating cable.

Claim 2

Dependent Claim 100 words

Claim 8

Dependent Claim 85 words

A pre-assembled floor heating panel for use with a self-regulating cable, and adapted to be used on an existing supporting surface comprising: a continuous rigid sheet of metal formed with at least one channel adapted to receive the self-regulating heating cable, and an insulating layer located beneath said continuous rigid metal sheet, said at least one channel partly penetrating said insulating layer, whereby the insulating layer provides insulation between a floor supporting surface and at least one channel of said continuous rigid sheet of metal.

Claim 9

Dependent Claim 85 words

A pre-assembled floor heating panel for use with a self-regulating cable, and adapted to be used on an existing supporting surface comprising: a continuous rigid sheet of metal formed with at least one channel adapted to receive the self-regulating heating cable, and an insulating layer located beneath said continuous rigid metal sheet, said at least one channel partly penetrating said insulating layer, whereby the insulating layer provides insulation between a floor supporting surface and at least one channel of said continuous rigid sheet of metal.

Claim 10

Dependent Claim 19 words

The pre-assembled floor heating panel of claim 7 , wherein each channel extends between opposite sides of the panel.

Claim 11

Dependent Claim 26 words

The pre-assembled floor heating panel of claim 7 , wherein at least one channel extends between two end points located on one side of the panel.

Claim 12

Dependent Claim 19 words

The pre-assembled floor heating panel of claim 7 , wherein the continuous rigid metal sheet is formed of aluminium.

Claim 13

Dependent Claim 19 words

The pre-assembled floor heating panel of claim 7 , wherein the insulating layer is formed of cellular plastics material.

Claim 14

Dependent Claim 163 words

A floor heating system adapted to be used on an existing supporting surface, comprising: pre-assembled panels, each of said panels being combinable with other ones of said panels to form said floor heating system, and each of said panels including: a continuous rigid sheet of metal, formed with at least one channel, at least one of said at least one channel extending between different sides of the panel, so that, when several of said panels are placed on a floor surface, a continuous channel is formed; an insulating layer located beneath said continuous rigid metal sheet, said channels partly penetrating said insulating layer, whereby the insulating layer provides insulation between a floor supporting surface and at least one channel of said continuous rigid sheet of metal; and a heating cable, fitted in said at least one channel, said heating cable having inherent properties to generate more heat when at a relatively cooler temperature and generate less heat when at a relatively hotter temperature.

Claim 15

Dependent Claim 163 words

A floor heating system adapted to be used on an existing supporting surface, comprising: pre-assembled panels, each of said panels being combinable with other ones of said panels to form said floor heating system, and each of said panels including: a continuous rigid sheet of metal, formed with at least one channel, at least one of said at least one channel extending between different sides of the panel, so that, when several of said panels are placed on a floor surface, a continuous channel is formed; an insulating layer located beneath said continuous rigid metal sheet, said channels partly penetrating said insulating layer, whereby the insulating layer provides insulation between a floor supporting surface and at least one channel of said continuous rigid sheet of metal; and a heating cable, fitted in said at least one channel, said heating cable having inherent properties to generate more heat when at a relatively cooler temperature and generate less heat when at a relatively hotter temperature.
