Are Evacuated Tubes affected by frost?
No. Traditional technologies are vulnerable to freezing in cold weather. Now you don’t need to compromise the system’s performance (for example by using chemicals like glycol) in order to prevent it freezing. Many traditional technologies require regular and costly maintenance programs for freeze protections. Evacuated tube technology, as used by the Endless Solar system, works extremely efficiently in cold climates. In Antarctica the British Research Station, Halley VI, has chosen to install evacuated tube technology to help preserve power and conserve energy. Evacuated tube solar collectors are the technology of choice in countries that experience extremes in temperature. For example, they are widely used in Germany, China and Canada.
