Description

TECHNICAL AREA

The invention relates to a heating element according to the features of the preamble of claim 1.

STATE OF THE ART

From the prior art, a variety of heating elements and mobile heating elements are known. These include, for example, heat fungi or hot air blowers. Disadvantageously, drafts and / or overheating often occur. This effect is avoided by flat heating elements or surface heating systems such as underfloor heating, since they have a lower base temperature due to their large area.

For example, the DE 200 15 859 U1 a heating element, in particular suitable as underfloor heating. This heating element is also flexible or mobile use. For this purpose, the heating element is connected to a heating device. However, there is a risk that the heating element or the heater expires after disconnecting from the supply line or air or dirt penetrate into the heating element. Thus, the heating element is not easy to use in a mobile way, since it must always be ensured that no liquid leaks.

DESCRIPTION OF THE INVENTION

The object of the invention is to provide an improved heating element, which minimizes the above-mentioned disadvantages and is widely used.

To achieve the object, the features of the characterizing part of claim 1.

A heating element which emits radiant heat comprises a hose line for a liquid heat source, a flow connection and a return connection, the flow connection having a first pressure-proof coupling and the return connection having a second pressure-proof coupling. This advantageously prevents the heat source or the heating medium from undesirably escaping from the hose line. This is particularly advantageous because the heating element can be easily transported after disconnection from a heater by these pressure-safe couplings. It is also advantageous that is prevented by the pressure-resistant coupling that air and / or dirt penetrates into the hose of the heating element.

In typical embodiments, the heating element has a trough. This results in the advantage that all items of the heating element can be accommodated in the tub. Advantageously, therefore, the heating element is easy to transport. Conveniently, the tubing is received in the tub.

Advantageously, the trough has an opening. Preferably, the opening is formed so that the flow connection and / or the return connection of the hose line exit through the opening of the tub. This results in the advantage that the heating element is a closed element with two external connections. It is also advantageous that the external connections are simple plug-in couplings. Thereby, the heating element can be easily connected to the leads of a heater for heating water.

Conveniently, the heating element, in particular the tub is closed at the top by a tread. This results in the advantage that the heating element is accessible as underfloor heating. Preferably, the tread surface of wood, a chipboard, metal, checker plate, plastic or laminate is formed.

Conveniently, the heating element can also be arranged as surface heating on the wall or free-standing in the room. This gives a mobile heating, which achieves good heating results with relatively lower flow temperature. In an arrangement of the heating element on the wall, a corresponding breather can be provided.

In typical embodiments, the tubing is prefilled with the heat source. This results in the advantage that the heating element is immediately operational at the site and does not have to be filled in a complicated manner.

Preferably, the heat source is a frost-proof pre-filled water heat source, and more preferably a glycol mixture. Most preferably, the heat source is a 30% glycol mixture. This results in the advantage that the heat source or the heating element is frost-resistant to about -20 °.

Conveniently, the hose is laid meandering. This has the advantage that a large cable length can be accommodated on a relatively small area. In typical embodiments, the tubing is laid in loops

Advantageously, the heating element has a clip rail for fixing the hose line. Preferably, the clip rail is attached to the bottom of the tub. This is especially preferred Heating element two clip rails on. This results in the advantage that the tubing can be securely fixed in a desired position in the tub.

In typical embodiments, insulating material is disposed in the tub. Preferably, the insulating material between the tub bottom and the hose is arranged. This has the advantage that the heat of the hose is not in the bottom of the tub, but upwards, in the direction of the tread, where the heat is needed, is discharged. An example of such an insulating material is polystyrene.

A particularly preferred use for the heating element is as a tent heater. Advantageously, a heating element according to the invention is approximately 20% more efficient than conventional tent heaters. Further preferred uses are: Halls, food stalls, toilets, outdoor or on exhibition stands. The fact that it is a surface heating, there is no drafts and the comfort of people who are in rooms that are heated with the heating element of the invention increases. Overheating, especially in the head area, such as in mushrooms, is avoided.

Separately, protection is claimed for a mobile underfloor heating with a heating element, the heating element being connected via a pressure-proof coupling to a heating station for heating water or another liquid.

In typical embodiments, a mobile floor heating comprises a plurality of heating elements according to the invention. Preferably, the heating elements are to be laid in the Tichelmann system. This results in the advantage that all heating elements then heat relatively evenly and no additional control valves are needed for hydraulic balancing.

In a further exemplary embodiment, in particular when several heating elements are combined to form a mobile underfloor heating, a plurality of the heating elements each have the feed connection and the return connection on opposite sides. This results in the advantage that the heating elements can be plugged together in a simple manner. The warm water then passes from a first heating element into another subsequent heating element. This has the advantage that the laying of the heating elements is possible even without the relatively expensive piping of the Tichelmann system.
