1. A hot water apparatus comprising:
a fluid circuit in which a fluid heated by a heat source circulates: a water circuit, connected to the fluid circuit via a heat exchanger, in which water circulates; a tank, connected to the water circuit, in which the water absorbing heat from the fluid at the heat exchanger is stored; a fluid temperature detector that detects a fluid temperature of the fluid circulating in the fluid circuit; a tank temperature detector that detects a tank temperature of the water stored in the tank; and a controller, the controller is configured to:
determine whether clogging exists by determining both of: (i) whether the fluid temperature detected by the fluid temperature detector is at or above a first threshold, and (ii) whether the tank temperature detected by the tank temperature detector is at or below a second threshold,when both of: (i) the fluid temperature detected by the fluid temperature detector is determined to be at or above the first threshold, and (ii) the tank temperature detected by the tank temperature detector is determined to be at or below the second threshold: issue, to a user, a notification indicating that the water circuit is clogged, andwhen at least one of (i) the fluid temperature detected by the fluid temperature detector is determined to not be at or above the first threshold, and (ii) the tank temperature detected by the tank temperature detector is determined to not be at or below the second threshold: do not issue, to the user, the notification indicating that the water circuit is clogged. |
