PROBLEM TO BE SOLVED: To provide a heat pump type hot water supply machine which can suppress that the adhesion of scales is left as it is until it becomes necessary to exchange a heating heat exchanger, or an apparatus main body including the heating heat exchanger.SOLUTION: This heat pump type hot water supply machine comprises: a heating heat exchanger for heating water; a pump for making the heating heat exchanger flow water; pressure detection means for detecting a pressure difference between pressure between the heating heat exchanger and the pump, or pressure at an inlet side of the heating heat exchanger, and pressure at an outlet side of the heating heat exchanger; and prediction means for predicting a time at which scales are clogged in a water flow passage, or a time at which the removal of the scales at the water flow passage becomes necessary on the basis of a detection result of the pressure detection means. |
