A hot water supply device and a controlling method thereof according to the present invention are for a separately-heating hot water mat having multiple separated heating regions. The hot water supply device includes: a valve including multiple separated pipes for separately supplying hot water to each of the separated heating regions of the hot water mat and individually controlling the hot water flows flowing in the separated pipes; and a control unit controlling the valve in order to continuously open the separated pipe connected to the heating region of the hot water mat of which a heating temperature is set to be the highest and intermittently open the separated pipe connected to the heating region of the hot water mat of which a heating temperature is set to be low in accordance with the set heating temperature. In the case of using the hot water supply device and the controlling method thereof, separate heating is possible with a single storage tank, a heater, a pump, and a valve. And an effect of preventing a noise increase is obtained. The purpose of the present invention is to provide the hot water supply device and the controlling method thereof capable of separately heating the regions of the hot water mat at different temperatures. |
