The split solar water heating is an active system, because it uses a pump with a controller to circulate the fluid between theheat pipe series solar collector and the storage tank, tank and solar collector are separate, while the collector is integrated in to the roof of the building, the tank and the pump station can installed anywhere of the building. The piping between the main components is made of brass and a special insulation with high temperature resistance for solar systems.
An Once Heat-exchange System is suit for climates where there is no risk of freezing. Recirculation freeze protection can be provided by the Recirculation feature in the controller. An Open Loop Water Heating System provides many advantages. It is the simplest and typically the least expensive active system to install. There is no heat exchanger, which allows efficient heat transfer directly to the water. The system operates at standard line pressure. It is simple to add capacity to the system if demand changes. The system integrates easily with existing systems.
