Abstract:
Heating installation (1) for area heating, comprising a burner (4) and a Stirling engine (2) thermally coupled to the burner (4), wherein the Stirling engine (2) comprises a closed pressure vessel (16) containing a working gas, the pressure vessel (16) comprising a first hot chamber (12) and a first cold chamber (13), and, adjoining the latter, a working chamber (17) containing a piston element (10), as well as a Stirling heat pump (3) comprising a second hot chamber (20) and a second cold chamber (21), the hot chambers (12, 20), the working chamber (17) and the cold chambers (13, 21) being in fluid communication with one another, the pressure vessel (16) being provided, at the level of the hot chambers (12, 20) and the cold chambers (13, 21), with, in each case, an external heat exchanger (24, 25, 26, 27), the first cold chamber (13) and the second hot chamber (20) being connected via their respective heat exchangers (25,26) to a hot water system (41) characterised in that the hot water system (41) comprises two heat exchangers (25,25',26,26') coupled to the first cold chamber (13) and the second hot chamber (20) respectively and a third heat exchanger (9) which is thermally coupled to the exhaust gases of the burner (4).
