    METHODS FOR MANUFACTURING A HEATING DEVICE, HEATING DEVICE MANUFACTURED IN ACCORDANCE WITH SUCH A METHOD, AND FURNITURE INCLUDING SUCH A HEATING DEVICE
    FIELD OF THE INVENTION
    The invention relates to methods of manufacturing a heating device, and to a heating device made in accordance with one of these methods. In addition, the invention relates to a piece of furniture comprising a heating device made in accordance with one of these methods.
    BACKGROUND OF THE INVENTION
    A known heating device which makes use of the properties of natural stone for heating a room is a stove that is built up of natural stone parts that can be heated by burning wood, for example, inside the stove. Such a heating device is designed to provide heat all around and is not designed to be placed against a wall. Another example of a heating device which makes use of the properties of natural stone for heating a space, which can be placed against a wall, is a natural stone slab which, by means of an electrically heated mat, as often used for floor heating, is heated. However, the heat generated by the electrically heated mat is only partially used to heat the natural stone slab. A large part of this will heat the air at the rear of the heating device, often the space between the heating device and the wall. However, without convection means to stimulate air flow, this heat cannot be optimally used for heating the space in which the heating device is placed. A disadvantage of both heating devices described above is that they cannot be connected to a water-filled central heating (central heating) system. Preference is given to connecting to a water-filled central heating system because the heat derived from it can often be generated in an energy-efficient and sustainable manner.
    A known heating device that can be connected to a water-filled central heating system comprises a marble plate which is mechanically connected to a radiator. However, the total surface area of the contact surfaces between the radiator and this plate is so small that the heat of the central heating water can only be used to a small extent for heating the marble plate. The marble slab has a more decorative function in this heating device.
    Another known heating device that can be connected to a water-filled central heating system, see patent document EP 0 025 959 A1, makes use of preformed slots in the production. The connection of the stony material with the pipe is not optimal because these grooves will always have to be wider than the pipes. Filling up this space later makes the production method cumbersome. Moreover, inserting slots in stone-like material, and certainly in natural stone, is very expensive. The manner described in EP 0 025 959 A1 somewhat circumvents this problem by using a rotary tool for manufacturing circular slots. However, the way in which the pipes must be arranged as a result is labor-intensive.
    No simple methods are known to the inventor for the manufacture of heating devices in which heat from central heating water is optimally utilized for heating a natural stone part.
    The object of the invention is to provide a simple method for manufacturing a heating device, which uses the properties of natural stone to heat a room, wherein the heat of water in a central heating system is efficiently used for heating the natural stone part. The properties of natural stone can in particular be used to increase the ratio of the radiation component to the convection component in the heating operation. Another characteristic of natural stone, for example granite, relates to the decorative function. Another object is to provide a simple method for manufacturing a robust, maintenance-friendly heating device with the advantages of a natural stone part, wherein the direction of the heating effect can be controlled at least in part. Moreover, it is an object of the invention to provide a heating device which is manufactured by such a method.
    Summary of the invention
    To this end, the invention provides a method for manufacturing a heating device, comprising the steps of, providing a natural stone part, providing a casting mold comprising a space, wherein a substantially flat side of the natural stone part, which flat side has a large forming part of the surface of the natural stone part, bounding at least one side of the space, arranging a conduit in the space, which conduit is suitable for connection to a water-filled central heating system, filling the space with a casting material that the pipe is surrounded at least for the most part by the casting material, allowing the casting material to pass into a solid state, the casting material being composed such that this results in the formation of a stony material, and dismantling the casting mold that the natural stone part remains as part of the heating device.
    The advantage of such a method is that a molded body can be made in which a pipe suitable for being connected to a water-filled central heating (central heating) system is included and which molded body can fit flush with the natural stone part. In such a heating device, heat transfer between the central heating water and the natural stone part largely takes place via the stone-like material which is heated by means of contact with the pipe in which the warm central heating water is again located. Stone-like material is generally heat-conducting, preferably the stone-like material has a high specific density so that the heat conduction is optimal. The contact surface between the molded body and the natural stone part is preferably as large as possible for optimum heat transfer.
    The casting material is, for example, a mortar, preferably an aluminate cement-containing mortar, see below for more details.
    The mold is formed, for example, by positioning the natural stone part such that a flat side is directed upwards and is horizontal. In case the natural stone part is plate-shaped, it should only be laid in a horizontal position. This flat side can be surrounded with raised edges, for example made of wood. The natural stone part and the raised edges form the mold in this example. Disassembling the mold according to the invention here only comprises removing the raised edges.
    The stony material and the natural stone part are preferably resistant to temperature changes. To this end, the natural stone part is preferably granite. Granite is very resistant to temperature changes, better than, for example, marble. The natural stone part can have a decorative function in addition to radiating heat. For this purpose, the heating device must be placed in the space such that the natural stone part faces the open space. Another advantage of granite is that it can be polished very smoothly so that it is easy to clean. Granite is very resistant to heat and heat exchanges and is shock-resistant.
    The specific heat capacity for cement and most stony materials is approximately 0.85 kJ / kg.K at 20 ° C, comparable to that of granite. Both materials can therefore retain heat to a similar extent. The thermal conductivity coefficient for cement in the dry state is approximately 1.7 - 2.0 W / mK and for granite approximately 3.0 W / mK which means that granite can conduct heat better than the stony material. From this it can be concluded that the convection part in the heating operation of the heating device on the side of the natural stone part, the front side, is greater than that on the side of the stony material, the rear side. The direction of the convection part of the heating operation is therefore partly controlled.
    Preferably, the conduit is first arranged in the space and then the space is filled with the casting material. This way the pipe will make contact with the natural stone part. If these contact surfaces are undesirable, for example because natural stone is used that cannot withstand this direct contact, it is preferable that the space is first filled with casting material and that the pipe is then arranged in the space. The term "filling the space with a casting material such that the pipe is surrounded at least for the most part by the casting material" should therefore also be understood to mean "filling the space with a casting material such that the pipe, after arrangement in the space , at least for the most part surrounded by the casting material. "
    The natural stone part is preferably plate-shaped and the mold is preferably such that the final shaped body, the stone-like material comprising the conduit, is plate-shaped. A plate-shaped heating device can hereby be manufactured, comprising two layers lying against each other, one layer consisting of a shaped body comprising the conduit, and one layer comprising the natural stone plate, which can be hung on a wall in a room, or which functions as a component of a device with other functions, for example a piece of furniture, see below. Of course, the ends of the pipe should not be included in the room because they serve to connect to the water-filled central heating system. By "filling the space with a casting material in such a way that the pipe is surrounded at least for the most part by the casting material", it is therefore understood that at most the entire pipe, with the exception of its ends, can be surrounded by the casting material . The ends must be left free in such a way that connection with a water-filled central heating system remains possible. Preferably, the space is deep enough to fully accommodate the pipe, with the exception of its ends, so that the side of the stony material forms a flat side and can optionally be polished or sanded smoothly later.
    The molded body is preferably connected to the natural stone part as a result of the curing of the casting material. If this is not the case, the molded body is preferably connected to the natural stone part by means of adhesives. See also below the method for separating the molded body from the natural stone part.
    In addition, the invention provides a method for manufacturing a heating device, comprising the steps of, providing a natural stone part comprising a space, arranging a pipe in the space, which pipe is suitable for being connected to a water-filled central heating system filling the space with a casting material such that the pipe is surrounded at least for the most part by the casting material, and allowing the casting material to pass over in a solid state, the casting material being composed such that this results in the formation made of a stony material.
    Once the space is provided in the natural stone part, the heating device can be manufactured in a very simple manner. A major advantage of such a method is that it requires no construction and dismantling of a mold. The resulting heating device will be robust because the shaped body, as mentioned above, is largely surrounded by the natural stone part. The space in the natural stone part will be milled in practice by a specialized company.
    Preferably, the space is deep enough to fully accommodate the pipe, with the exception of its ends, so that the side of the stony material forms a flat side and can optionally be polished or sanded smoothly later.
    Preferably, the conduit is first arranged in the space and then the space is filled with the casting material. This way the pipe will make contact with the natural stone part. If these contact surfaces are undesirable, it is preferable that the space is first filled with casting material and that the pipe is then arranged in the space. The term "filling the space with a casting material such that the pipe is surrounded at least for the most part by the casting material" should therefore also be understood to mean "filling the space with a casting material such that the pipe, after arrangement in the space , at least for the most part surrounded by the casting material. "
    When the natural stone part and the resulting molded body are plate-shaped and together form a layered heating device, the ends of the pipe preferably project through an end face of the heating device. The method according to the invention therefore also comprises the step of providing at least one recess in the natural stone part, which recess is suitable for passage of the supply and discharge conduit. The natural stone part is preferably in the form of a shallow trough with two recesses, one for the supply line and one for the discharge line, which two recesses are located in an upright edge on one side of the heating device.
    The above methods may also include the step of incorporating suspension means into the casting material prior to the step of allowing the casting material to pass into a solid state. The suspension means are in this way well anchored in the stony material so that they are suitable to hold the weight of the heating device.
    The advantage of both methods is that it is not necessary to freeze slots for passing through heating medium, for example hot water.
    In a preferred embodiment, the casting material comprises an aluminate cement. Aluminate cement is a calcium aluminate based cement as opposed to Portland cement containing calcium silicates. Aluminate concrete and mortar can be cured quickly, has increased chemical resistance and high wear resistance, and is particularly resistant to higher temperatures. The casting material can be, for example, a mortar consisting of aluminate cement, a filler, such as sand, and water.
    In yet another preferred embodiment of a method according to the invention, this also comprises the step of providing an opening in the natural stone part, and arranging a discharge pipe in the space such that after the step of leaving it in a fixed state starting from the casting material, the drain line connects to the opening, the drain line being suitable to be connected to a water drain system.
    A shower tray, for example, can be manufactured with such a method. The natural stone part then forms, for example, the side to be accessed from the shower tray. A bathroom can be heated in such a way without leaving extra space for a heating device. Natural stone is more often used to form a shower tray. Therefore, it is possible to use existing shower trays. With such a method it is also possible to manufacture a piece of furniture with an integrated washbasin, the top side of the piece of furniture being formed by the natural stone part.
    The invention also provides a method for manufacturing a heating device, which method comprises the steps of, providing a natural stone part, providing a molded body made of a cast stone-like material, in which a pipe, which pipe is suitable for are connected to a water-filled central heating system, is surrounded by the cast stone-like material, and the thermal connection of the natural stone part and the shaped body.
    By "thermal connection" it is understood that after connection of the two parts, heat transfer between them is possible. The connecting layer must therefore be heat-conducting.
    In this method, the manufacture of the shaped body is carried out separately from the natural stone part. This can be beneficial with regard to logistics. One company provides the natural stone part and the other company provides the form body. Thereafter, the heating device is created by a thermal connection. In this method, the natural stone part can also comprise a recess to allow the pipe to run through the natural stone part or comprise an opening to enable water drainage when the heating function is combined with a water drainage function. The molded body may accordingly also comprise a discharge line or a passage therefor. The stony material is preferably made by curing a mortar comprising aluminate cement.
    The cast stone-like material preferably comprises finely ground natural stone. The favorable properties of natural stone, including the high heat capacity and the good heat conduction, can be transferred to the molded body with such a method.
    The pipe is or is preferably arranged in such a pattern that the countercurrent principle can be applied to the heat transfer from the pipe. Such a principle allows better and more even heat transfer to the stony material. The heat transfer from two pipe sections running in the opposite direction runs via the stony material.
    In addition, the invention provides a heating device made in accordance with a method as described above.
    When the pipe is connected to the water-filled central heating system, the stony material will be heated by the heat of the central heating water, and this heat will then be transferred to the natural stone part. The heat from the central heating water can also heat the natural stone part via the contact surface between the pipe and the natural stone part.
    Due to the natural stone part and the stone-like material that for the most part encloses the pipe, the ratio of the radiation part to the convection part in the heating effect of the heating device can be high. A chamber with such a heating device therein can therefore be heated in a comfortable manner. The natural stone part, preferably granite, partially heats the space by means of radiant heat and moreover via air flowing along the natural stone part, convection heat, and also has a decorative function.
    The invention also provides a piece of furniture comprising a heating device as claimed in any one of the preceding claims. Thanks to the possibility of designing the heating device according to the invention as a plate-shaped part, it can be incorporated into a piece of furniture. The heating device can, for example, serve as a shelf of an open cabinet or as the top of a closed cabinet. For this it is required that the cabinet can be placed in a room such that the heating device can be connected to a water-filled central heating system.
    Brief description of the figures
    The invention is explained below with reference to non-limiting preferred embodiments of heating devices and a non-limiting preferred embodiment of a piece of furniture according to the invention. Therein: figure 1 shows a schematic cross-section of a preferred embodiment, figure 2 shows a schematic top view of the conduit arranged in the space, and figure 3 shows a schematic cross-section of a preferred embodiment of a heating device according to the invention in the form of a shower tray, and figure 4 shows a preferred embodiment of a piece of furniture according to the invention.
    Description of the preferred embodiment of the invention
    Figure 1 shows how the heating device (1) is suspended on a wall in such a way that the natural stone part (2) faces the space to be heated. It can be seen that the pipe adjoins the natural stone part (2) and is further surrounded by the stony material (7), which is created by the solid material passing over, in other words, by the curing of the cast material. The natural stone part (2) here is one whole with the raised edge. Therefore, no casting mold is required for the manufacture of such a heating device. It is only necessary that the natural stone part is in a horizontal position with the raised edges pointing upwards for filling the space with the casting material. Figure 2 shows that the pipe is arranged in the space (4) according to a countercurrent principle. The natural stone part (2) comprises two recesses (8) for passage of the incoming and outgoing pipe (5). In Figure 3, the heating device (1) according to the invention has the form of a shower tray. The natural stone part (2) comprises an opening (9) for draining water via the drain line (10) which is arranged in the space before filling the space with casting material. Figure 4 shows a cupboard (12), a piece of furniture whose underside is formed by the heating device according to the invention.
