<p>The device comprises a condenser (3), an expansion valve (4) and a heat pump (1) with a coolant circuit which is guided over a compressor (2). An evaporator (5) forms two heat exchangers (6,7) that are heated with air as a heat source. The coolant is alternately guided over one heat exchanger, over the expansion valve and over another heat exchanger. An independent claim is also included for a method for operating a device for warming a heat carrier for a heating system.</p> |
