。 The hot water pouring pipe branched from the hot water outlet pipe of the hot water supply heat exchanger is connected to the bathtub water circulation reheating pipe, and the hot water heated by the hot water supply heat exchanger is passed through the hot water pouring pipe and the circulation reheating pipe. An automatic bath that pours hot water into a bathtub, detects the water level in the bathtub with a pressure sensor installed in a circulation reheating pipe, and stops pouring hot water into the bathtub when the water level reaches a set water level. In the pot, a valve is opened and closed in the circulation reheating pipe upstream of the pressure sensor by the difference between the force set by the atmospheric pressure and the spring, and the force that moves the valve body by the pressure in the circulation pipe. An automatic bath characterized in that a negative pressure stop valve is provided, and when the pressure inside the circulation reheating pipe becomes negative, the negative pressure stop valve is closed to prevent water from leaking in the circulation reheating pipe. Device to prevent water from draining in the pot.
