Abstract

The invention relates to a floor or wall heating panel and a system embodying the same, which, by the use of a one-piece copper pipe (2) of about 6 mm external diameter interposed between respective pairs of overlapping panel section having cooperating grooves (7) therein, permits of the heating arrangement having an overall thickness of 12 mm, which does not result in any manner of disturbance, even in subsequent installation in old residential property. <IMAGE>

Description

SPECIFICATION Floor and wall heating panel The invention relates to a floor and wall panel heating arrangement which is distinguished by its small thickness, absence of corrosion risk and high reliability.

The use of coils of steel or plastic tubing with a large internal diameter for floor heating is wellknown, the system being made up of individual components through which pre-heated water flows. The necessary coupling fittings however, require so much space that their subsequent installation in old residential property is no longer possible.

The invention is based on the problem of providing a flooring and wall panel heating system, which is only about 12 mm in thickness and which can be employed without difficulty as a substitute for the former stove heating system.

The problem is solved in the invention by the provision of pairs of panels, displaced in relation to each other both in the flow direction and transversely thereto, with recessed grooves of semi-circular cross-section on the one side for the accommodation of a continuous double coil of copper piping about 6 mm external diameter without any coupling components, through which flows about 1-2 litres per minute of pre-heated liquid.

The invention will now be described further, by way of example only, with reference to the accompanying drawings in which: Fig. 1 shows a pair of panels constructed and arranged in accordance with the invention, there being recessed semi-circular grooves in one face of each panel, the individual panels being displaced in relation to one another both in the direction of the individual pipes and transversely thereto, the arrangement being shown to a scale of about 1:10; Fig. 2 shows a section on line Il-Il of Fig. 3 drawn approximately to full size; and Fig. 3 illustrates a heating surface produced in accordance with the invention, again to a scale of 1:10.

Referring now to the drawings, a long copper pipe 1 of 6 mm external diameter and 1 mm wall thickness is bent into a double coil 2, one end of which is connected to the heating arrangement at 3, is reversed at a short-radius bend 4 and is led back to the heating system at 5. In the case of new constructions, this double coil of copper piping could simply be attached to an inner wall having a thin layer of insulating material, a protective coating, which would not affect the copper, then being applied. In the example shown, it is assumed that the heating arrangement is to be subsequently applied to an existing wall and, in accordance with the invention, panels 6 of glassfibre reinforced polyamide of about 6 mm in thickness, with grooves 7 of semi-circular crosssection on one side, are secured to the wall.

The grooves 7 are asymmetrically positioned in relation to the centre of the panels 6, so that, on placing the sides containing the grooves together, the copper pipe is firmly encircled and an overhang 8 in the panels is produced transversely to the pipes. In this way, it is ensured that any compressive forces acting on the panels will not lead to transverse stressing of the copper pipes, which could otherwise be expected, particularly in the case of floor heating. Special panels 11 to 14 are necessary for the return bends 9 and 10, as compared with the straight lengths of piping.

Hydraulic fluid has proved to be the best liquid heating medium.

1. Floor or wall heating panel characterized by pairs of overlapping panels of glass-fibre reinforced polyamide or ceramic material displaced in relation to one another both in the longitudinal direction of the piping and transversely thereto, provided on the one side with recessed grooves of semi-circular cross-section to receive respective runs of a continuous heating coil.

2. Floor or wall heating panel as claimed in Claim 1, characterized in that the heating coil comprises copper piping of about 6 mm outside diameter.

3. Floor or wall heating panel as claimed in Claim 1 or 2, characterized in that the copper coil is in the form of a double coil.

4. Floor or wall heating panel as claimed in any one of the preceding claims, characterized in that supply and return piping are provided at a convenient location.

5. Floor or wall heating panel substantially as hereinbefore described with reference to and as illustrated in the accompanying drawings.

6. A floor or wall heating system comprising a plurality of panels as claimed in any one of the preceding claims arranged in abutting side-by-side disposition.
