API Energy Active System, where API Energy Solar Panels are placed on the roof and API Energy Storage Calorifiers can be placed anywhere inside or outside the building. In this case we need a pumping system to circulate water throughout the system from storage tank heat exchanger to solar panel and from solar panel to storage tank heat exchangers. These systems are slightly complicated and require a number of components. The controls need to be designed understanding the area and application as the heat absorption and demand will vary place to place.

API Energy can also offer with overheat protection with API Energy Cooling Heat Exchanger  which is preferable for Systems with more number of panels and buildings with unbalanced demand. This will protects the collector and the solar fluid from becoming super heated when the load is low and the intensity of incoming solar radiation is high.
