Abstract
A hot-water heat pump that is capable of reducing installation costs and installation space and also reducing the heating time of a hot-water route, and a method of controlling the same are provided. The hot-water heat pump () is provided with a hot-water-heat-pump main unit () that includes a thermal output heat exchanger that absorbs heat from a heat-source route and outputs heat; hot-water route (and) that receive heat outputted from the thermal output heat exchanger; a three-way valve () provided in the outlet-side hot-water route (); and a controller that controls the hot-water-heat-pump main unit () and the three-way valve (), wherein the controller controls the size of openings of the three-way valve () so that a portion of the outlet-side hot-water route () leading out of the thermal output heat exchanger is guided to an upstream side of the thermal output heat exchanger.
