PURPOSE:To supply hot water of a predetermined temperature instantaneously from the start of use, by a system wherein a controlling valve provided in an inflow passage and a throttle part provided in a water-side pipe are controlled according to a signal from a temperature-detecting part provided in the vicinity of the inflow passage. CONSTITUTION:Stagnating cold dead water is passed through the temperature- detecting part 15, original hot water flows from a main heat source machine 1, and when a temperature of 45 deg.C is detected, the controlling valve 16 is fully closed, the inflow passage 8 is thereby closed, and only a flow through a bypass passage 11 is obtained. On the other hand, the throttle part 17 is so designed that the throttle opening is increased according to the temperature detected by the part 15, so that hot water supplied from the machine 1 and passed through the bypass passage 11 and water passed through the water-side pipe 4 are mixed with each other at the second junction 13, and the mixed hot water is supplied through a terminal hot water supplying port 14. Accordingly, predetermined hot water can be continuously obtained from the moment a hot water side valve 5 and a water-side valve 6 are opened. |
