Abstract
A heating pump includes a pump body and a driving motor. The pump body includes a pump housing with a water inlet and a water outlet, a heating member fixed in an interior of the pump housing, and an impeller connected with the driving motor. The heating member includes fittings and a heating coiled pipe connected between the fittings and bent into an arc. The impeller is disposed at an upper part of the pump housing, one end of the driving motor is disposed adjacent the impeller, and the heating coiled pipe circles around a radial side portion of part of the driving motor. The heating pump has a rational design and high heat exchange efficiency. The safety auxiliary motor has a low requirement for power. The axial size of the water pump is significantly reduced.
