An air source heat pump system comprises tubing providing a refrigerant circuit (18); a compressor (27) for compressing the refrigerant; a condenser (28) for cooling the refrigerant; and an expansion device (29) configured to reduce the pressure of the refrigerant. The system also comprises a first evaporator part (26); a second evaporator part (35); and a receiver (34) configured to connect the first evaporator part and the second evaporator part. The receiver is configured to allow gas phase refrigerant to enter the first evaporator part from the receiver and liquid phase refrigerant to enter the second evaporator part from the receiver.
