HOT WATER SUPPLY APPARATUS AND HOT WATER SUPPLY METHOD

摘要

There are provided a hot water supply apparatus and a hot water supply method. The hot water supply apparatus includes: a heater heating introduced water to a heater heating capacity; an ejection valve adjusting an amount of water ejected from the heater; a temperature sensor measuring an ejection temperature of ejected water; and a controller proportionally controlling a degree of opening of the ejection valve according to a temperature difference between the ejection temperature and a target temperature. The controller calculates a variation in the ejection temperature value and adjusts the ejection valve degree of opening of the ejection valve according to the calculated temperature variation.
