HEAT PUMP TYPE HOT WATER SUPPLY DEVICE AND METHOD OF STERILIZING HOT WATER

摘要

A heat pump type hot-water supply device (1) including a hot water storage tank (5) and a hot water circulation circuit (50) is provided with a bactericidal component generator (60), such as a discharge device (65) for generating a streamer discharge, in order to prevent development of bacteria, such as Legionella, at low cost. The bactericidal component generator (60) generates, at a temperature lower than or equal to that of hot water in a hot water circulation circuit (50), a bactericidal component so as to bring about an effect on the hot water.
