Thanks to the ROOS^®-solar ribbed tubes, your water is heated up very rapidly!
 

• The special moulding of the ROOS-solar ribbed tubes heats up your pool very rapidly, by free solar energy. They are made of special plastics of very high quality. This material is higly UV-resistant. It remains stable against temperatures from -45°C to 130°C (-49°F to 266°F) and against chemicals which are used in pool water treatment..
  
  
• The collector which has been developped especially for pool-heating is most efficient at temperatures of about 23°C to 32°C (73°F to 90°F). This is ideal, since these temperatures offer most fun and comfort when swimming.

  Larger surface area

• The ROOS-solar ribbed tube has a  t r e b l e surface area as compared to a tube of the same diameter but with a smooth surface. The special shape of the ROOS-solar ribbed tubes guarantees a rapid heat absorption and a rapid transmission of that heat to the water which flows through the collector.

   Advantage: Your pool is heated up faster.

• Furthermore, the special moulding makes the ROOS-solar ribbed tubes stable, flexible and vacuum-resistant.

Smooth surface = smaller surface area
= less heat absorption

Ribbed surface = larger surface area
= rapid heat absorption
