Method for controlling hot-water temperature of a boiler according to direct water temperature in the boiler with fast hot-water function

摘要

PURPOSE: A warm water temperature control method is provided to rapidly supply hot water in a pre-set temperature in an initial use of hot water. CONSTITUTION: A supply temperature of water is determined and saved, when a user uses hot water without a rapid water heating function. The heating-off and on temperature is set so that hot water is supplied in a fixed temperature, when the user uses a rapid water heating function. The heating by boiler is stopped in the heat-off temperature and the heating is started by the boiler in the heat-on temperature. The temperature of the heating supply water passing through a heat exchanger(4) is measured.
