Abstract
A hot water supply apparatus according to an embodiment of the present disclosure includes a first heat exchanger that heats heating water and a second heat exchanger that generates hot water, a first temperature sensor that is installed on a first flow path through which the supply water supplied by the first heat exchanger flows to the second heat exchanger and measures a temperature of the supply water, a second temperature sensor that is installed on a second flow path through which return water of the supply water cooled after heat exchange with the second heat exchanger flows to the first heat exchanger and measures a temperature of the return water, and a controller that predicts the temperature of the supply water based on the temperature of the return water measured by the second temperature sensor and preforms hot water control based on the predicted temperature of the supply water.
