Abstract
A central heating radiator has a body 10 of cementitious material, a flow duct 13 embedded within the body 10 for heated water with an inlet and an outlet (16, fig 1),17 disposed externally of the body for coupling to a central heating system, and brackets 18 for mounting the radiator to a support structure (e.g. a wall). The duct 13 can be turns or coils of copper pipe, and the cement Portland filled with sand, acrylic polymer and/or glass-fibre. The duct 13 can be suspended within the mould until material in the partially filled mould has set, and then brackets 18 encapsulated in a further layer of material. The cementitious material is inexpensive, and can be moulded with a relief pattern, has a higher thermal mass than steel and thus the radiator remains warm for a prolonged period after the heating is turned off.
Description
Central Heating Radiator This invention relates to a radiator for a central heating system of the so-called wet type.
Central heating systems generally comprise a plurality of radiators through which hot water is circulated from a boiler. In use, the radiators become hot and the heat from the water is transferred to the room in which the radiator is situated.
Typically central heating radiators are formed of steel, being a material which is relatively inexpensive, easy to form and having a good specific heat. However, a disadvantage of steel is that it can rust and react with the water inside produce iron oxide in the form of sludge. Another disadvantage of steel radiators is that they can be rather unattractive in appearance unless complicated and costly designed are utilised.
We have now devised a central heating radiator which alleviates the above-mentioned problems.
In accordance with the present invention there is provided a central heating radiator comprising a body of cementitious material, a flow duct embedded within said body for carrying heated water and having an inlet and an outlet disposed externally of the body for coupling to the respective flow ducts of a central heating system, means being provided on the body facilitating mounting of the radiator to a wall or other support structure.
The cementitious material of the body is relatively inexpensive and can easily be formed into any desired shape, for example in a correspondingly-shaped mould.
Cementitious materials have a higher thermal mass than steel and thus the radiator advantageously remains warm for a prolonged period after the heating has turned off.
The embedded flow duct is preferably a pipe formed of any suitable material although it is preferred that it comprises a non-ferrous material, such as copper, having a relatively low specific heat value. In the latter case, the copper is preferably of a form which is relatively resistant to corrosion by any lime contained in the cementitious material.
Preferably the embedded duct comprises a plurality of turns or coils to maximise the length of time that the hot water remains in the radiator.
Preferably the cementitious material comprises ordinary Portland cement.
Preferably the ordinary Portland cement is mixed with a filler material such as sand or another aggregate.
Preferably the ordinary Portland cement is mixed with an acrylic polymer.
Preferably the ordinary Portland cement is mixed with a reinforcing material, such as glass-fibre.
Preferably the body comprises a flat panel having a front face and a rear face.
Preferably the front face comprises a surface relief pattern, which can easily be produced in a mould of a corresponding shape.
Preferably said mounting means comprises members which project from the rear surface and comprise inner ends embedded in said body.
Preferably the inlet and outlet of the duct are connected to valve couplings for connecting to the respective flow ducts of the central heating system.
The inlet and outlet of the flow duct may extend from a side or end face of the body.
Alternatively, they may extend from a rear face.
Also in accordance with the present invention, there is provided a method of forming a central heating radiator, the method comprising embedding a flow duct for hot water in a body of a cementitious material and providing means on the body to facilitate mounting the body to a wall or other support structure.
Preferably the body is formed by casting the cementitious material in a mould.
Preferably the flow duct is suspended in the mould during casting.
Preferably the suspension is removed once the cementitious material has at least partially set, the mould then being further filled with cementitious material.
Preferably said mounting means are inserted into the mould after the initial cast such that their inner ends become embedded by the subsequent cast.
Preferably the mould is vibrated during casting.
Embodiments of the present invention will now be described by way of examples only and with reference to the accompanying drawings, in which: Figure 1 is a rear view of an embodiment of central heating radiator in accordance with the present invention; Figure 2 is a sectional view along the line u-u of Figure 1; Figure 3 is a sectional view along the line ui-ui of Figure 2; Figure 4 is a front view of the central heating radiator of Figure 1; Figure 5 is a rear view of an alternative embodiment of central heating radiator in accordance with the present invention; and Figure 6 is a sectional view along the line vi-vi of Figure 5.
Referring to Figures 1 to 4 of the drawings there is shown a central heating radiator comprising a generally rectangular body 10 formed of a moulded cementitious material. The cementitious material comprises a ratio of one part sand, one part cement, 5% acrylic polymer and 4% glass-fibre reinforcement. The body 10 comprises a major front surface 11 which may be formed with a surface relief pattern 12 which may be painted.
The body 10 is formed in a tray-like mould having a bottom surface which is formed with the surface relief pattern 12 and elongate copper pipe 13 is embedded in the cementitious body 10, the pipe 13 having an inlet 14 and an outlet 15 which extend out of the rear surface of the body 10 and then downwardly to a point below the bottom edge of the body 10. Valved couplings 16,17 are fitted to the inlet and outlet 14,15 of the pipe respectively. The pipe 13 comprises a plurality of 180 degree turns such that the pipe has a plurality of successive transverse sections disposed from one end of the body to the other. In this manner, the overall length of the pipe 13 inside the body 10 is approximately 5 times longer than the width of the body 10.
However, it will be appreciated that the length of the pipe 13 and the number of turns can be varied to suit particular applications. The turns of the pipe 13 lie in a plane which extends parallel to the front face 11 of the body 10.
The radiator is formed by suspending the pipe 13 inside the mould, for example using wires or other filaments. The mould is then partially filled with the cementitious material to at least partially encapsulate the pipe 13. Once the cementitious material has at least partially set, the wires or other filaments are then removed. A plurality of elongate fastening members 18 having an enlarged head are then placed in the mould whereupon a further layer of cementitious material is added to encapsulate the heads of the fastening members 18. Once the cementitiuous material has set, the radiator can be removed from the mould and fixed in situ by attaching the fastening members 18 to complementary members on the wall or other support structure.
Referring to Figures 5 to 7 of the drawings, there is shown an alternative embodiment of a central heating radiator in accordance with the present invention, which is similar to the radiator of Figures 1 to 4 and like parts are given like numerals. In the embodiment, the inlet and outlet 14,15 of the pipe 13 are disposed behind the rear surface of the body 10 of the radiator, such that they are hidden from view.
It will be appreciated that a central heating radiator in accordance with the present invention is simple and inexpensive in construction, yet provides an extremely efficient heating device which is aesthetic and durable in construction. The body can be cast to any shape and can be provided with any desired pattern on its front surf ace.
