FAQ1.ÿ Can the solar collector be used in cold condition?Re: This solar collectors can be used in temperatures as low as -30?, although performance is greatly reduced in such extreme conditions. Good heat output is still achieved in mild sub-zero conditions.2.ÿ What maintenance of the solar collector is required?
Re: Under normal circumstances no maintenance of the system is required. Due to the shape of the tubes regular rainfall and wind should keep the tubes clean. Should a tube even be broken it should be replaced. This, however, is an inexpensive and easy job. Any “handy” person can install a new tube (while adhering to local health and safety regulations).ÿOur solar collectors can operate with several broken tubes, however the efficiency will be reduced slightly.
