Abstract (en)
[origin: EP2009360A2] This heat pump type hot water supply apparatus has a hot water storage tank (22) capable of supplying stored hot water to outside of the tank (22), and a heat pump unit (10) for heating hot water in the hot water storage tank (22) to a set-up temperature (31a) set up beforehand. The hot water supply apparatus newly calculates a set-up temperature so that the energy of hot water in the hot water storage tank (22) becomes equal to a unit period consumption energy calculated based on the energy of hot water supplied to outside of the tank (22) for a past predetermined term. Furthermore, the hot water supply apparatus has the display (46) and speaker (47) for outputting newly calculated set-up temperature based on difference between newly calculated temperature and current set-up temperature (31a).
