The purpose of the present invention is to provide a hot water supplying apparatus which enables supply of hot water by utilizing waste heat of a pipe and a boiler as a heat source if there is a small quantity of residual hot water to use therefor, the residual hot water being required when using hot water of an instantaneous boiler, and a method for utilizing waste heat of a hot water supplying apparatus. The hot water supplying apparatus of the present invention for achieving said purpose comprises: a sensible heat exchanger for heating a heating fluid by means of combustion heat from a burner; a hot water supply heat exchanger for generating hot water by means of a heat exchange between the heating fluid heated by the sensible heat exchanger and direct water, and supplying the hot water to a faucet; and a pump for circulating the heating fluid via a heating fluid flow path which connects the sensible heat exchanger and the hot water supply heat exchanger, wherein the hot water supplying apparatus comprises: a signal reception unit for receiving a final hot water use signal; and a control unit for stopping the operation of the burner on the basis of the signal received by the signal reception unit and controlling the pump to circulate the heating fluid.
A hot water supply apparatus which includes a sensible heat exchanger configured to heat a heating fluid using combustion heat from a burner, a hot water supply heat exchanger which generates hot water using an exchange of heat between the heating fluid heated in the sensible heat exchanger and direct water and supplies the generated hot water to a faucet, and a pump configured to circulate the heating fluid through a flow path of the heating fluid which connects the sensible heat exchanger to the hot water supply heat exchanger, the hot water supply apparatus configured to receive a final hot water use signal that a user transmits when an additional amount of hot water that is needed remains while the user is using the hot water,
A method of utilizing waste heat of a hot water supply apparatus which includes a sensible heat exchanger configured to heat a heating fluid using combustion heat from a burner, a hot water supply heat exchanger configured to generate hot water using an exchange of heat between the heating fluid heated in the sensible heat exchanger and direct water and supply the generated hot water to a faucet, a pump configured to circulate the heating fluid through a flow path of the heating fluid, which connects the sensible heat exchanger to the hot water supply heat exchanger, and a flow rate sensing unit configured to sense a change in flow rate of water supplied by opening or closing of the faucet and output a flow rate signal,
