With rising energy prices, there has been a need to find new sources of energy. In this case, energy sources have been introduced which are characterized in that the energy is obtained at a relatively low temperature level1a or that the efficiency substantially improves as the temperature level decreases. The annual supply time of solar heat is extended and the efficiency is improved, the heat coefficient of the heat pump increases if the energy can be utilized, for example, at a temperature of + 35 ° C instead of + 60 ° C.

Residential heating systems have recently developed 10 so that the above-mentioned 35 ° G is sufficient for most of the heating season, but the hot water temperature should preferably be + 60 ° C, min. + 50 ° C. However, relatively little high temperature water is required, since e.g. the temperature of the wash water is generally + 38 ° C, in which case cold water is mixed with the water heated to + 60 ° C until the temperature of the mixture is suitable.

The following invention, the features of which are set out in the claims, is intended to provide a system which substantially increases the use of low temperature energy sources and saves the energy to be purchased. The description refers to the numbering of the accompanying drawing.

It is already known to divide the domestic hot water heater into two parts, either in the upper and lower part of the same tank or in two separate tanks (1,2). The purpose of the preheating-25 coil (3) is to cool as efficiently as possible the part of the tank into which the solar heat (4) is introduced, and thus to improve the use of the "free" solar heat. The after-heating coil (5) raises the water temperature to its final value with "paid" energy, e.g. an electric heater (6).

According to the invention, after the "free" stage, the hot water is no longer necessarily heated, but could be led to the operating point by means of a pipe (7) between the coils (3 * 5). In many cases, the temperature of the water from the pipe (7) is related to the alarm. Depending on the case, 2 62898 should be mixed with cold or hot water, i.e. whether the pipe (7) should be connected to the mixer's cold or hot water connection. The temperature of the pipe (7) can be limited to a temperature of, for example, · \ · 35 ° C by means of a mixing connection (8), in which case it can be connected to the hot water supply of a normal thermostat or the like. In this case, it is always possible to get a wash from the mixer! water (+ 38 ° C) obtained almost entirely from the part of the tank heated by "free" energy, instead of being heated to + 35 ° C-> 10 4 60 ° C and then mixed with cold water as appropriate.

An even better system is obtained if a special mixer is made for the system, i.e. a water fixture (9) with three inlet water connections: cold (10), lukewarm (7) and hot (li). In this case, the temperature can be freely selected from the mixer, 15 and a limit switching is not necessary.

The type of mixer can be known for a long time, e.g. a ball, slide, cylinder, etc. automatically adjustable or manually adjustable thermostatic mixer or single lever mixer. It is essential for the invention that in addition to cold and hot water 20, it is also possible to introduce water to the mixer with other Energi ataso11a.

In addition to the above-mentioned application examples, the invention can also be applied to non-domestic water systems within the scope of the claims, i.e. the valve structure does not necessarily have to be a so-called "mixer", nor water of the medium to be treated. The heat exchanger does not necessarily have to be of the "coils" type, but the liquid of the tanks, for example, can be distributed according to the principle shown.
