How Solar heater works for you


The sun shines on the Special heating absorption board and the surrounding air absorbs heat. Nakoair® solar air collector/heater operates by taking in air at the bottom of panels, and through a special construction inside the panel, the air is heated by the sun several times catching the most heat and then delivered into the room or dwelling without wasting energy. The heated or fresh air is blow into the house by a fan, driven by photovoltaic panel.
