An energy-saving heat pump device includes first, second, third, and fourth pipes connected in sequence in a loop. A condenser is mounted between the first and second pipes. An expansion valve is mounted between the second and third pipes. An evaporator is mounted between the third and fourth pipes. A compressor is mounted between the first and fourth pipes. The compressor compresses and outputs a coolant mixture including at least two coolants. The coolant mixture in the first pipe has a pressure of 24-30 kg/cm2G and a temperature of 80-125° C. The coolant mixture produces heat while the coolant mixture passes through the condenser. A temperature of water outputted from the condenser is in a range of 45-98° C. The coolant mixture produces cold energy for a cooling medium of the evaporator while the coolant mixture passes through the second pipe, the expansion valve, the third pipe, and the evaporator.
