An open loop system is 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.
1) reliable and efficient twin-glass solar tubes;
2) copper heat pipes for rapid heat transfer;
3) easy plug-in installation;
4) free maintenance;
5) suitable for mains pressure water (up to 8 bar/116psi);
6) corrosion resistant silver brazed copper header;
7) aluminum frame;
8) powder coated (black, brown or silver) aluminum casing;
9) stable solar conversion during the day;
10) the perfect solar collector for domestic solar water heater systems;
11) ideal for commercial solar water heating applications.
