Definitions

  • the invention relates to radiant heating from a heat radiation surface, which can consist of marble, granite or marbleized limestone, metal, ceramic, glass or a combination thereof.
  • a heat radiation surface which can consist of marble, granite or marbleized limestone, metal, ceramic, glass or a combination thereof.
  • Two different heating elements are arranged in connection with insulation on the back of the radiation surface.
  • the given prior art is characterized in that radiant heaters, in particular made of natural stone, are known which have an electric heater on the back.
  • the electrical heaters are arranged in such a way that they are arranged in the natural stone by milling it or are glued to the natural stone via a mesh.
  • the electric heater then heats the radiant heater made of natural stone or other materials and can then heat up the room after a relatively long heating phase.
  • the disadvantage here is that heating up a room via the radiant heater with an arranged electrical or other heating source takes a relatively long time, since the existing heat radiation surface, for example made of marble, first has to be heated up. This can take a few hours, which is a disadvantage.
  • the aim of the invention is to find an arrangement of radiant heaters on the back of these which corresponds to all possibilities of using convection heaters or alternative energies and significantly reduces the energy expenditure.
  • the object of the invention is to realize a radiant heater from a heat radiation surface, which consists of marble, granite or marbleized limestone, metal, ceramic, glass or their combinations, and thus suppress the prior art. Radiant heating is found, which reveals the possibility of quickly heating up an existing space and subsequently remaining in an effective temperature range.
  • the invention was achieved in that a radiant heater is realized from a heat radiation surface, which consists of marble, granite or marbleized limestone, metal, ceramic, glass or their combinations, with an electric heater or an electric heater on the back of the radiation surface is arranged for alternative energies and an inner rear wall with an internal insulation is carried out via the electric heater or the electric heater for alternative energies. This internal insulation with the corresponding internal rear wall prevents thermal expansion towards the installation wall.
  • a second convection heater is placed on the inner rear wall with the insulation included. This is useful for the rapid heating of a given room with this convection heater.
  • This convection heater can consist of different heating sources. An electric heater is preferably used here, which is connected to normal network operation. It is also possible to install a normal hot water radiator from a given heating system. Via this convection heater, which is useful for immediate heating of a room, an outer rear wall is installed as a final element for the entire heating area. This outer back wall has convection slots on the respective outer edges, top and bottom, which means that the heated air escapes to the room immediately.
  • the convection heating is operated via a corresponding regulation or control until a certain temperature is given in the interior of the room to be heated, with which the convection heating is then switched off. Subsequently, a further heating of the radiant heating or the heat radiating surface is then given via the existing electrical heating or the electrical heating for alternative energies.
  • the given inner rear wall and the outer rear wall are fastened to the rear with corresponding mounting bolts.
  • the entire radiant heater with the existing heat radiation surface and the attached electrical or alternative heating elements or the convection heater is arranged on a wall or other surfaces using given mounting bolts.
  • a technical solution is carried out, with multi-stage heating elements in combination with a controller, in particular a 3-point controller, being attached to the rear of the radiant heater.
  • the given radiant heating plate is always kept in the effective temperature range for radiant heating.
  • the controller especially the 3-point controller, switches off part of the heating element when the Rau target temperature is reached and continues to run at low power. This keeps the plate in the effective range as Radiant heating. Maintaining the temperature at a low output requires considerably less energy than when completely heating a cooled radiant heater.
  • Two setpoint temperatures are entered on the 3-point controller, which are determined by a room temperature measurement, so that they are in an effective range of heat emission from the radiant heater.
  • the multi-stage heating element thus only runs with a part of the entire heating element. If the lower room setpoint is reached by lowering the temperature due to low radiation emission from the radiant heater, this switched-off part of the heating element is switched on again and thus a full output of the entire heating elements is achieved. Due to this full performance of the heating elements, the upper target room temperature is reached again and a certain part of the heating element is switched off again. On the basis of this connection and disconnection between two target temperatures, considerable energy savings are achieved, since the radiant heating does not have to be heated from a cooled state via heating elements. Due to the relatively constant plate temperature of the radiant heating, a more comfortable room climate is achieved, the thermo-mechanical load is lower and the lifespan of the radiant heating is extended.
  • the multi-stage heating element provides greater operational reliability Example of frost protection heating during an absence.
  • Figure 1 shows a radiant heater, which is composed in the above embodiment as follows.
  • a radiation surface 1 made of natural stone is used as the heat radiation surface.
  • This can be marble, granite or marbled limestone.
  • the essential properties of this natural stone heating result from the fact that high-quality and carefully selected natural stones are used. This makes every natural stone heater a stylish one-off.
  • marble is defined differently. In geological science, marble is a metamorphic rock transformed from limestone. In the construction industry, in trade and in the vernacular, every solid and thus polishable limestone is called marble.
  • the "real" that is, the metamorphic marble is made by contact or Regional metamorphosis formed from limestone. It is coarse-crystalline and, like limestone, monominerally composed of calcite. Individual crystals are coarsened at the expense of others, so that the whole aggregate has a sugar-like appearance.
  • FIG. 1 a given natural stone is used in FIG.
  • An electric heater 3 is applied to the natural stone.
  • Electric heating 3 heating strands meandering laid. This laying of the heating wire of the electric heater 3 is carried out on a glass fiber mesh. This laying of the heating wire on the glass fiber mesh is fixed in the transverse direction with an adhesive. Furthermore, it is given that the heating wire of the electric heater 3 is electrically insulated by means of a corresponding PVC coating. The ends are connected to the possibility of connecting an electrical network or an alternative energy supply. Basically, a glass fiber mesh fabric with an attached heating wire of an electric heater 3 is used here. This glass fiber mesh fabric with the heating strands of the electric heater 3 is then arranged with a further adhesive on the back of the natural stone. Thus there is direct contact between the electric heater 3 and the natural stone.
  • An electric heater 3 Another possibility for using an electric heater 3 is to use a heating element for alternative energies 2 for the electric heater 3.
  • This decision as to which electrical heating element 3 or heating element is used for alternative energies 2 depends on the area of application of radiation heating.
  • An inner rear wall 5 is now arranged via the installed electrical heater 3 or a heating element for alternative energies 2. Insulation 4 is provided within this inner rear wall 5, with the result that heat loss is prevented with the corresponding mounting wall. Consequently the electrical heating 3 or a heating element for alternative energies 2 gives an optimal spread of the thermal energy over the radiation surface 1.
  • a convection heater 6 is now arranged on this inner rear wall 5 of the radiation heater. This convection heater 6 can also be an electric heating element.
  • a further outer rear wall 7 is then arranged over the convection heater 6, the respective upper and lower edges of the outer rear wall 7 being provided with convection slots 8.
  • the convection heater 6 is used, when certain buildings are heated, to ensure that the use of the convection heater 6 results in an immediate heating of the room by switching on this convection heater 6.
  • Convection heater 6 is automatically switched off, and further heat radiation is then over the
  • Heating 3 or a heating element for alternative energies 2 performed.
  • a heating element for alternative energies 2 for the first heating circuit which is then on the
  • Radiation surface 1 is applied, additional climate via the convection heater 6 can in appropriate climatic conditions, such as calm, darkness, cold spell, etc.
  • This utility model is a heater.
  • This heater is a combined radiant and convection heater.
  • the primary energy for this heating is electrical energy.
  • the radiant heat is generated by one or more electrical heating elements 3 or 2 behind or in a heat radiation surface or radiation surface 1. Natural stones are preferably used as the radiation surface 1. However, metal, ceramic, glass or combinations thereof can also be used. Pure radiant heating has two heating elements. One heating element is used for conventional mains operation. The other heating element is used to feed electrical energy from alternative energy sources, such as photovoltaics, wind turbines or the like, or a completely normal electrical heater.
  • the heating element which is fed with energy from alternative energy producers, works primarily.
  • the heating element such as the convection heater 6, which is fed from the public network, is only switched on when the heat output currently required by the alternative energy producers is no longer sufficient, for example due to the onset of cold, calm, darkness, etc.
  • the electrical heating elements 2 and 3 are technically designed so that the electrical energy can be fed directly from the system without inverters, stabilization, etc., which significantly reduces the technical system costs.
  • the heating is a combination between radiant heating and convection heating.
  • Another electric convector is integrated in the radiant heating.
  • the electrical converter is used to quickly heat up the premises. When the setpoint is reached, the convector is switched off and the radiant heating continues to work alone.
  • FIG. 2 shows a combination of a radiant surface 1 made of natural stone, an electrical heating element 3 from given electrical energy and a convection heater 6, which is represented here as a warm water heater 9.
  • This hot water heater 9 is given to an inlet 10 or outlet 10 a of the hot water.
  • the mode of operation of this embodiment variant shown in FIG. 2 is identical to that in FIG. 1, which means that a convection heater ⁇ in the form of a hot water radiator 9 is switched on in the event of rapid heating or no electrical energy. If a certain room temperature has been reached, this hot water heater 9 is subsequently switched off, with the result that further radiation activity of the radiation surface 1 of the radiation heater is carried out via the electrical heating elements 3.
  • FIG. 3 shows a block diagram of the 3-point controller 11 with the radiant surface 1 and integrated divided heating element from parts 13 and 12. It can be seen that on the radiant surface 1 on the back a divided heating element over a Neutral conductor is attached, which is divided into the respective heating elements 12 and 13. These heating elements 12 and 13 are electrically connected to a 3-point controller 11.
  • This 3-point controller 11 is connected to a given room temperature sensor for signaling purposes. In the 3-point controller 11, two different target room temperatures are specified. It is important that the 3-point controller is used to switch the divided heating element on and off in its respective parts.
  • FIG. 4 shows a diagram 'of the behavior of the temperature at the time, from which it is apparent that in the switching points 1 *, t 2, and 3 t of the 3-point controller 11 each have a connection and disconnection of a part of a heating element 13 is effected. If the setpoint 1 of the room temperature is reached in the upper point, which is set in the 3-point controller, the heating element part 13 is switched off via the controller. The radiant heater 1 thus only runs over the heating element part 12. The cooling that takes place as a result of the incomplete utilization of the heating elements results in a temperature decrease over the course of time. This means that a further setpoint for the room temperature is reached in the lower range.
  • the heating element part 13 is then switched on again via the 3-point controller, and the radiant heater 1 is subjected to full power from the two parts of the heating elements 13 and 12.
  • the upper setpoint of the room temperature is thus reached again, and the heating element part 13 is switched off again. It is thereby achieved that the radiant heater 1 is always acted upon by the respective heating element parts 12 and 13 in the effective range of the temperature and thus the advantages already described on this page are achieved.
