The system having a sanitation mode of operation whereby when the system determines that a predetermined heating condition is met, the water is subjected to heating by the water storage heater. The process includes the sanitation initiation steps of: determining a time period Pw that has passed since the water last satisfied a predetermined sanitation-satisfaction criterion of the system; then comparing Pw with the predetermined maximum allowable period Pw.max; then if Pw is equal to or greater than Pw.max, placing the system in the sanitation mode of operation; then determining whether the predetermined heating condition is met; and then if the predetermined heating condition is met, subjecting the water to heating by water storage heater. |
