<p>A heating installation comprising a first circuit (2) containing a first medium, a second circuit (3) containing a second medium, a first heat generating arrangement (4) arranged in the second circuit, a second heat generating arrangement in the form of a heat pump (5), and at least two heat transferring devices (2OA, 20B) arranged in series in the first circuit for transferring heat to the first medium in the first circuit. A first one (20A) of said heat transferring devices arranged in series is arranged to transfer heat from the second medium in the second circuit to the first medium in the first circuit. A second one (20B) of said heat transferring devices arranged in series is arranged in the first circuit upstream of the first heat transferring device (20A) and comprises a heat exchanger (40), which constitutes a subcooler of the heat pump and which is connected between the con¬ denser (5d) and the expansion valve (5f) of the heat pump for transferring heat from the working medium of the heat pump in its condensed state to the first medium in the first circuit.</p> |
