PROBLEM TO BE SOLVED: To provide a hot water supplier which can perform the energy saving, regardless of the degree of recognition to energy saving of a user. SOLUTION: In a hot water supplier which has a hot water supply circuit 36 and an additional stoking circuit 37 having heat exchangers (a hot water supply heat exchanger 25 and a bath heat exchanger 26), and whose hot water supply circuit 36 is provided with a water flow detector (a quantity-of-hot-water- for-supply sensor 17) for detecting the water flow of the hot water, and which performs remote control by a remote controller 2, the remote controller is provided with an indicator which indicates the set temperature of the hot water for supply, and the indication of the set temperature of hot water for supply is put off after a specified time (T1) after the water flow detector (quantity-of- hot water-for-supply sensor 17) detects the nonexistence of flow of hot water, and is lit after the water flow detector (quantity-of-hot-water-for-supply sensor 17) detects the flow of hot water for supply.
