thermally and thermally conductive elastic materials, the outer chamber 12 is provided with a thrust 20 of elastic material with a thermodynamic shape memory attached at its ends to the bases 14 of the outer chamber 12, the suction pipe 8 is connected to the inner chamber II, and the feed 7 is connected to outside 12.

Heat source movement booster 5 and heat source 2 are provided with a bypass line 21 with shutoff valves 22. Expansion vessel 23 is connected to the heating circuit, supply line 7 is connected to the storage tank 24 of the hot water supply, and suction 8 is connected to the source 25 of the water supply. There are control valves 26 and 27 in the heating circuit. The coupling 17 consists of a leading 28 and a driven 29 parts, the latter being combined with the impeller 15 supported through the rolling bodies 30 onto the body 13 where the support is attached to the rolling bodies 31. Chambers 11 and 12 communicate with each other through heat-insulated kakal 32. The suction pipe is heat-insulated. As a material for traction 20, for example, titanium nickelide with a response temperature of 60 ° C and a return temperature of 100% of the form 40 ° C can be used. In the heated state (over 60 ° C), the ha 20 has the shape shown in FIG. , and when cooled (below 40 ° C) takes the form shown in Fig.2.

The system works as follows.

With the heat source 2 turned off, the pipelines 3 and 4 are filled with cold water, the element 1 of the driving force is in the position shown in Fig. 2, the impeller 15 is fixed. When the heat source 2 is turned on, the water in the pipelines is heated and natural circulation occurs in the heating circuit. Through heat-conducting walls 19, heat is transferred to the water in the outer chamber 12, and the heating 20 is heated, which, at a temperature above 60 ° C, is compressed, compressing in turn the chambers I and 12 (FIG. 3) and pushing the heated water through valve 9 to the supply pipe 8 of the hot water circuit and then to the storage tank 24, and the cold water from the inner chamber 11 is squeezed out through the passage 32 into the chamber 12.

This cold water cools the heat 20 and it regains its shape (Fig. 2). The chambers 11 and 12 are diluted by sucking cold water from the water supply source 25 through the valve 10. At the same time, the lower base 14 pushes down the screw pair 1 6 with the coupling 17. The driving part 28 of the coupling 17 engages with the driven part 29 and drives the impeller 15 to rotate.

The rotation of the impeller 15 enhances the circulation of water in the heating circuit. All processes are periodically repeated.

In the summer, when the heating system is not operating, the shut-off valves 22 on the bypass line 2 are opened.
