In a heat pump, in which the first medium by a pump (2) is circulated in an enclosed system (1-7) with a heat exchanger (4), in which the first medium is emitting heat to a second medium, the closed system is oil-filled. The pump (2) is an oil engine, and the oil tubes of the heat exchanger (4) have a flow passage section compressing the oil to a substantial pressure. Hereby the oil is heated without cooling off the surroundings, and the heat pump offers a very high rate of efficiency. |
