The split solar water heating is an active system, because it uses a pump with a controller to circulate the fluid between the heat 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.

• The main components of Once heat-exchange split solar water heating:
  1) Solar collector
  2) Solar Workstation including:
      Circulation pump,
      Check valve,
      intelligent solar controller with sensors
      rass connector
  3) Solar pressurized tank from 100L to 500L
  
  
• Advantages of split solar water heating:
  1) No disorder water tank on your roof
      split solar water heating systems is using a high efficiency solar collector on your roof
      and a high pressurized storage tank in the house. Integrated in to the roof of the building
      perfectly.
  2) The perfect solar collector for domestic hot water heating system can be combined with
      existing energy source, such as your gas water heater, electric water heater, boiler, etc.
  3) There have an auxiliary heating device--electric heater booster in the tank, so providing hot
      water in case of cloudy or rainy days, you will no need to worry about it.
  4) No water inside the tube, the system can still in service even with several tubes breakage.
  5) Completely automatic.
  6) Cut out your energy bills
      Hot water heating (on average) accounts for 26% of your annual energy bill. With a solar
     water heater you could generate enough solar energy to heat 70% of your hot water,
      FREE, year after year!
