Abstract
Abstract A heating element (12) is described for use in flooring, preferably for pigstys (3). The heating elements consist of a liquid filled chamber (16). The liquid in the chamber is brought into heat transmitting connection with a conduit (24) connected with a heat source. The connection between the conduit (24) and the chamber (16) do not have to be pressure tight, as no pressure occurs in the chamber (16). Therefore, a relatively simple connection may be established and there will only be a small risk of leakage.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
198 words
A heating element (12) for use in a building and of the kind that is built up from modular elements having engagement means for interacting with corresponding engagement means on other modular elements, which heating element comprise chamber (16,34,35) containing a heating liquid and which chamber constitutes one side of a heat exchanger, the other side of which heat exchanger is constituted by a conduit (24) extending through the chamber (16) and connecting a number of heating elements (12), which conduit is a liquid- or steam conveying conduit that is fastened in liquid tight connection with passageways (25) in two mutually facing walls of the chamber, characterised in that the heating element (12) is adapted for use in a floor, that parallel grooves (9) are arranged at the underside of the heating equipment in a location corresponding to underlying supporting rails (4) and which function is to engage the rails (4), that the chamber (16) is provided immediately under a floor surface (18) of the element (12), and that at least a part (17,31) of the chamber has such a depth under the floor surface (18) that the passageways (25) are at level under the support rails (4).

Claim 3
Dependent Claim
15 words
A heating element according to claim 1, characterised in that the conduit (24) is straight.
Claim 4
Dependent Claim
61 words
A heating element according to claim 1, characterised in that the passageways (25) are constituted by threaded pipe stubs (20) made integrally with the side walls of the chamber and which interact with packing (23) and a union (22) that may be screwed into the stub (20) for expanding the packing (23) radially into a tightening engagement about the conduit (24).
Claim 5
Dependent Claim
51 words
A heating element according to claim 1, characterised in that the chamber (16) has a mainly T-shaped cross section as viewed in a direction perpendicular to the engagement grooves, and that the conduit (24) passes through the chamber in a position at the bottom of the stem (17) of the T.
Claim 6
Dependent Claim
47 words
A heating element according to claim 4, characterised in that there is provided a number of distributed connecting points (28) between the top (18) and the under side (29) of the part of the chamber (16) that is constituted by the crossing branch (19) of the T.
Claim 7
Dependent Claim
39 words
A heating element according to claim 1, characterised in that the conduit (24) is a continuous liquid conduit which extends without joints through a number of chambers arranged along a line and is made of a heat transmitting material.
Claim 8
Dependent Claim
27 words
A heating element according to claim 1, characterised in that it is made with integral engagement means together with supporting grooves and thus constitutes a modular element.
Claim 9
Dependent Claim
30 words
A heating element according to claim 1, characterised in that it is made as an insertable element which is made for mounting in a frame element constituting a modular element.
Claim 10
Dependent Claim
59 words
A heating element according to claim 1, characterised in that the chamber (16) is connected with at least upwardly directed chamber sections (34), which form the walls for a heating box (36) that is found on the formed floor, and that the further upwardly directed chamber sections (34) are connected with the chamber (16) under the floor surface (18).
Claim 11
Dependent Claim
39 words
A heating element according to claim 9, characterised in that the further chamber sections (34) are provided with a conduit extending through the further chamber sections, and which is connected directly with the conduit placed under the formed floor.
Claim 12
Dependent Claim
14 words
The heating element of claim 1, wherein the building is a stable for livestock.
Claim 13
Dependent Claim
12 words
The heating element of claim 6, wherein the material is metallized plastic.
Claim 14
Dependent Claim
12 words
The heating element of claim 9, wherein the walls include ceiling (35).
