An efficient heat pump is disclosed, the heat content of the refrigerant flowing out of an existing condenser is reduced by sub-cooling using an additional condenser. The heat reduced during the sub-cooling phase is added to the evaporator to superheat the refrigerant during evaporation phase. Removing heat from condensation phase (which is otherwise wasted) of the refrigeration cycle and adding that heat to the evaporation phase (which requires additional heat) may enhance the efficiency of the heat pump.
