PROBLEM TO BE SOLVED: To provide a bathroom heater which can optimize the temperature (distribution) in the bathroom and does not cause noise. SOLUTION: This bathroom heater comprises a temperature sensor 25 for detecting temperature in a bathroom. A controller 27 outputs commands for changing temperature of hot water which is supplied from a heat source unit 3 and for changing the airflow rate of a circulating fan 15 in accordance with the signals from the sensor 25. When the relation between a temperature (bathroom temperature TB) detected by the sensor 25 and a temperature (TS) set by a user is TS-TB>=T1, the temperature of hot water is rendered high and the airflow rate is rendered strong. When the relation is T1>TS-TB>T2, the temperature of the water is rendered low and the airflow rate is rendered strong. When the relation is TS-TB<=T2, the temperature of hot water is rendered low and the airflow rate is rendered weak. In this way, an atmosphere which is closer to a set temperature can be realized by determining a hot air temperature and an airflow rate on the basis of the difference between the set temperature and an actual temperature.
