Abstract
The Present invention provides a hot water supply device in which the temperature of hot water stored at high temperature in a hot water storage tank or the like can be lowered to a temperature for use at which the risk of scalding is prevented, when supplied to a hot water usage part, without need for cold water to be mixed with the high-temperature hot water. A hot water supply device comprising a hot water storage tank, a cold water supply line for supplying cold water to the hot water storage tank, a hot water supply line for supplying hot water from a hot water storage tank to a hot water usage part, and high-temperature hot water discharge prevention means provided, along a hot water supply channel of these lines, for preventing high-temperature hot water discharge to the hot water usage part. The high-temperature hot water discharge prevention means is configured from a heat exchanger means provided to effect heat exchange between hot water of the hot water supply line and cold water of the cold water supply line and a flow rate control means for controlling the flow rates of the hot water in the hot water supply line and cold water of the cold water supply line. The control of this flow rate control means is executed in response to the temperature of the hot water and the cold water.
