PROBLEM TO BE SOLVED: To provide a hot water supply equipment to effectively utilize thermal energy exerted on cooling water by a heat-exchanger. SOLUTION: Water delivered from water purifying equipment 1 through a water delivery pump 3 and a water supply pipe 4 is supplied to a secondary fluid flow passage 37 of a heat-exchanger 31. Steam flowing in a primary fluid passage 32 of a heat-exchanger 31 is condensed and water the temperature of which is increased by thermal energy of which the steam is deprived is stored at a hot water storage tank 6 through a hot water feed pipe 5. Further, water increased in temperature is supplied to various buildings through a hot water feed pipe 7, a hot water feed pump 8, and a hot water distributing pipe 9, and thermal energy exerted on water through condensation of steam is effectively utilized. |
