Heliocol is one of the least efficient collectors on the market. Their big claim is that they do not cause roof rot - which is a lot of rubbish. None of the solar collectors out there (that have been around for more than 10 years) damage roofs unless they leak - then you have a problem...

For a comparison of collector efficiencies, check out the ratings at the Florida Solar Energy Center's web-site. Bear in mind that the tests results posted are the best the products can do. The tests are conducted at next to zero wind speed. THe greater the wind speed the less heat a solar collector will deliver. Collectors with exposed tubes (especially Heliocol) cool off much faster than those with no exposed tubes (like Techno-Solis).
If you're looking for a solar system for an above-ground pool, then go with the cheaper 4' x 20' design - they only last 5 years at best. If you have an inground pool -go for a better quality product..
