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.
