3549号公報参照）。(Prior Art) Conventionally, as shown in FIG. 2, a heating source 54 is provided in a hot water storage tank 51 having a water supply port 52 and a hot water supply port 53, and a hot water supply pump 55 is provided at the hot water supply port 53. There was a hot water supply type hot water supply device in which the outlet side of the hot water supply pump 55 and the bottom part of the hot water storage tank 51 were connected by a bypass circuit 57 having an electromagnetic opening / closing valve 56 (for example, the actual open water shovel 60-12
(See Japanese Patent No. 3549).

中でも湯を利用できるようにしようとするものである。This hot water storage type hot water supply device includes a plurality of temperature sensors 58a, 58b,
When the temperature distribution in the hot water storage tank 51 is detected by 58c and becomes equal to or higher than the determination value, the electromagnetic opening / closing valve 56 is opened and the hot water supply pump 55 is driven to cause forced convection in the hot water storage tank 51 to cause the hot water storage tank 51.

Although a forced bypass convection is generated in the hot water storage tank 51 by providing the bypass circuit 57 with the intervening bypass circuit 57, since the forced convection uniformly occurs in the entire tank, the circulation flow velocity around the heating source 54 is small and the heat transfer performance is high. The effect of improving the above was small. Also,
Since forced convection does not occur until the hot water temperature in the hot water storage tank 51 reaches the available temperature, there is a problem that the heating efficiency is low in the low temperature range.
