Split Pressurized Solar Thermal Collector with Heat Pipe
  • SFB series
High Pressurized solar thermal collector. Elegant appearance, easy installation and high efficient heat pipes bring you nice bath.

"This kind of products use Evacuated Tubular Solar Thermal Collector Tube with Heat Pipe as its heat-absorb element. So it can be connected to the pressurized system.

 
These top-of-the-range solar panel heat collectors are suitable for heating domestic hot water, swimming pools etc - even in winter! One unit is adequate for an average household (3-4people), and it is modular, so you can add more if required. A single panel is sufficient for a 200litre cylinder, but you can fit 2 or more for high water usage, or for heating swimming pools or underfloor heating. Some types of renewable energy are only available in certain locations, however free solar heating is potentially available to almost every house in the world! "
