The introductory part of this diploma work contains a basic thought for the application of the heat pumps cascade connection and further I describe its function and define the notion of an optimum middle temperature.Then the direct comparison of two heats pumps cascade connection with an one-stage heat pump is shown there in a concrete example. The main part of the work is aimed to the determination of the most suitable variant for the heating and for the preparation of a hot service water in a benchmark family house. The systems of heatings are provided in options of a low-temperature floor heating and hot-water radiators. Both types of the heat pumps supply the warm to every heating system. It results into four possibles alternatives of the building heating.Besides of the alternatives mentioned above, a new variant of optimalised cascade connection was arisen during this work elaboration . The first stage of this connection which supplies the warm to the floor heating is disconnected out of the heating season and the second stage provides only a hot service water warming. The results of this work showed us that just this variant of a cascade connection causes savings in energy in comparison with an one-stage heat pump. In the conclusion of this work there are discussed the reached results and indicated the possibilities of a practical exploitation.
