The WOLF CRK 12 vacuum tube collector achieves excellent yields even with low insolation or less than optimal orientation. This assures you of solar-generated heat and hot water even in spring and autumn, and means you also save on costs for oil or gas during these seasons. The CRK can be designed on a modular basis, i.e. you can connect several collectors in series to suit the space available on your roof. Even if conditions on your roof are not ideal, you can still enjoy solar central heating and hot water with the CRK 12.
The WOLF CRK 12 tube collector provides central heating backup all year round, assuring you of a warm and cosy home and plenty of hot water. It harvests 15 % more solar energy than a flat-plate collector of comparable size. This means you can make optimum use of the sun's rays, especially in spring and autumn. What's more, the CRK 12 takes up only a little of your roof space and delivers its output even if the angle of inclination is less than ideal. Treat yourself and your family to the highest levels of energy efficiency, reliability and durability, as well as the satisfying sense that you are making the most of solar energy.
