3. Solar Heat Application System with Built-in Solar Battery Yuwaita Excellent Atsutaro

Yuwaita Excellent Atsutaro

Winner: Yazaki Sogyo Features:Uses solar battery as power source for the heat-concentration pump to cut running costs to a great extent. Due to the adoption of a method which links the hot water tank directly to the tap water, high pressure is attained for hot water supply. Initial costs are also reduced by integrating the heat-concentration device and hot water tank into a compact size.
