The utility model relates to a rotatable mid-deep layer coaxial pipe ground source heat pump heating system which comprises a rotatable mid-deep layer coaxial pipe system, a circulating pump, a heat pump unit and a heating area. The system has two sets of independent circulations, the first set is geothermal water circulation, the geothermal system is connected with a first circulating pump to convey high-temperature geothermal water to a heat pump unit, a heat pump heats the heating water to a certain temperature through the geothermal water according to the temperature needed by heating, and the used low-temperature geothermal water returns to the geothermal system; and the second set is heating water circulation, heating water is subjected to primary heating through the heat pump unit and then is subjected to auxiliary heating through a solar heat collector or directly supplied to a heating area according to the temperature of the heating water, and low-temperature heating water flowing out of the heating
