Abstract (en)
[origin: EP4269904A1] A heat pump water heater and a heat pump apparatus each include: a first circuit unit in which water is circulated, and which heats the water by heat exchange between the water and refrigerant; a second circuit unit including a plurality of flow passage components, connected to an external heating load, and provided to cause the water heated by the first circuit unit to flow to the heating load and to release heat at the heating load, and mix the water heated by the first circuit unit with return water that has transferred heat; a housing unit in which the first circuit unit and the second circuit unit are housed; and a fixation sheet metal to which the flow passage components of the second circuit unit are fixed, and which is attached to the housing unit.
