The invention relates to a method for operating a heat pump of a heating system of a vehicle for heating air for and/or in the interior of the vehicle, comprising a refrigerant circuit having at least one compressor, a first heating heat exchanger on the high-pressure side, a second heating heat exchanger, an expansion mechanism and an evaporator, the invention relates to a method for operating a heat pump in a refrigerant circuit, in which the refrigerant is operated in a supercritical manner on the high-pressure side in the refrigerant circuit, and the high pressure in the refrigerant circuit is adjustable, comprising the following steps: determining a value for the high pressure in the refrigerant circuit that is optimal for the efficiency of the heat pump; the high pressure in the refrigerant circulation loop is increased to a value above the efficiency optimum, and the increased high pressure is achieved, where the power distribution of the transfer of thermal power in the first heating heat exchanger relative to the transfer of thermal power in the second heating heat exchanger corresponds to the desired power distribution. The invention also relates to a heating system that can be controlled in such a way and to a vehicle having the same.
