KENSOL solar collector designed for flat roof provides an independent source of heat and long, reliable operation. The efficiency of HEAT PIPE collectors depends on their proper inclination, which is in the range of 15° - 50°. Inclination other than the recommended one can cause a significant reduction in efficiency, and in some cases even lead to complete immobilization of the system. The most important parameters for the operation of a solar collector are its power and efficiency. No fluid flows through the HEAT PIPE pipes, which means that the pipe can be dismantled at any time without draining the entire system. KS-58/1800-30 is the optimal use of space and the highest comfort that a solar collector can provide.
