After the water tank is full, vacuum tubes absorb solar energy and then heat water inside tank directly. The water heated is stored in the water tank. Tap water inflows into water tank through internal coil, and at the same time tap water absorbs the heat energy from the hot water storaged in the tank by the coil, and turn the tap water into hot water instantly.
