<p>The present invention refers to a device intended for use with a system comprising a heat pump with an evaporator and a condenser, in which a heat transfer medium in a heat transfer circuit, heated up by means of the evaporator and a compressor, is arranged to give off heat to a first liquid flow via a first heat exchanger part, wherein said system further comprises a second heat exchanger part to give off heat to a second liquid flow, wherein said second liquid flow is arranged for circulation through a heat emission system, wherein the device includes means for heating water in a water reservoir, wherein said reservoir includes an inlet for entering water to be heated and an outlet for discharging heated water, wherein the water in the reservoir is heated by means of said first liquid flow. A closed circuit, separated from said heat emission system, is used to circulate said first liquid flow through said first heat exchanger part, wherein the circuit for heat emission passes through the water reservoir. The invention also relates to a method, a heat pump and a heating system.</p> |
