Waste heat from paper mills, for example, is used partly as energy input to a heat motor, partly as energy input to a heat pump. The heat motor drives the compressor of the heat pump which means that no external high grade energy has to be supplied to drive the heat pump. The heat leaving the hot side of the heat pump can be utilized readily, directly or after heating of feed water, for example, possibly for vaporization thereof, for example, in the process that left the waste heat.
