DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a heat installation for premises, water being used as a heat transmitting medium.
Such conventional heat installations comprise loosely layed visible piping or piping accommodated in walls and floors respectively. Said installations are designed throughout either as one- or as two-pipe-systems. In all of the cases the installation has been performed by artisans with a manual individual pipe laying and assembly operation, which is very expensive and time-consuming. In case such a system is to be installed in already finished houses, usually it is required that the floors and walls be torn open for an invisible pipe laying, or if the pipe laying is to be visible, said pipes will constitute a strongly disturbing factor and also usually will emit heat in places where heat is not required, which to some extent is true as regards pipe laying in walls and floors, in which the heat insulation is unsatisfactory. Invisible pipe laying may involve risk of leakage, which is hard to discover, with severe damages as a result, when leakage has been discovered after usually an extended period of time, and the development of mould, rot and rust. Irrespective of whether an installation is done in connection with the erection of a building or in an already finished building painters, carpenters, floor-layers etc. have so far been required to be able to complete their work or else they were required to perform additional work, when the installation contractors have completed their work. The problem whether to select an one-pipe- or a two-pipe-system has also often been difficult to solve. One of the two systems may have been suitable for e.g. one specific module or building element, while the other one had been suitable for other modules. However, for practical reasons it has been necessary to consistently select one single system and thus, one has been unable to combine the two systems in a way which is advantageous for a partial area. To let laymen install the heat system has been inconceivable and in certain countries not allowed, partly due to the above-mentioned drawbacks and risks.
The object of the present invention is to suggest an improved heat installation, in which water is used as a heat transmission medium and which avoids the drawbacks mentioned above and promotes the state of the art in this field in various respects.
This object is attained by mainly designing an installation of the type set forth above. Thanks to such a design it is very easy to use such a system as a so called do-it-yourself installation, i.e. an installation done by laymen, e.g. home and apartment owners. This system can easily be delivered as a module system suitable for all conceivable sizes, designs and applications. Those buildings, in which the system is to be installed, advantageously can be completed, i.e. finish-painted and upholstered, provided with floor covering etc. before the system according to the invention is to be installed. This means that the system according to the invention advantageously can be installed in new as well as in old buildings. When so called prefabricated houses are erected, it is not necessary to pay attention to the pipe laying and wall and floor elements can be provided even more finished than what has been possible in certain cases so far. All kinds of pre-layout in this respect can be avoided and the house or apartment owner can himself to a great extent select the design of the system or change the same subsequently without any appreciable problems. Consequently, e.g. houses having electrical heat elements, which act directly, can in a quick, simple and inexpensive way be provided with a heat installation ;according to the present invention with water as a heat transmitting medium. Also, an installation according to the present invention does not require any closed so called loops. Thus, parts of the system advantageously can be installed as branches, which are terminated in optional areas. In this way it is e.g. possible, in the way shown in FIG. 1 of the accompanyin
