PROBLEM TO BE SOLVED: To provide a hot washing water injection unit capable of preventing the damage of a bath circulation heating circuit by preventing excessive pressure from being loaded to the bath heating circuit by stopping hot water (or water) injection when it is detected the faucet for hot washing water injection of a hot washing water injection conduit is closed in the case of injecting hot water (or water) from the hot washing water injection conduit to a washing machine. SOLUTION: When the injection of hot water for washing is started by operating a remote controller RC for hot washing water injection, a three-way valve 9 is switched from a circulation heating position to a hot water injecting position and the operation of a circulation pump 6 is started. It is discriminated whether the output (detected value) of a pressure sensor 8 is lower than a preset specified value or not and when it is lower than the specified value, the normal state of opening a faucet 11 for hot washing water injection is discriminated. Then, the operation of the circulation pump 6 is stopped, a two-way valve 5 is switched from an opening position to a closing position and a solenoid valve 19 for hot water injection is opened. When the output (detected value) of the pressure sensor 8 is higher than the specified value, the operation of the circulation pump 6 is stopped, and the closing error of the faucet 11 for hot washing water injection is displayed.
