What are the best design and installation practices for evacuated tube collectors in cold climates?
Evacuated tube collectors (ETCs) are a type of solar thermal system that use vacuum-sealed glass tubes to absorb and transfer heat from the sun to a fluid. They are more efficient and versatile than flat plate collectors, especially in cold climates, where they can operate even in freezing temperatures and low solar radiation. However, ETCs also require careful design and installation to avoid potential problems and optimize their performance. In this article, you will learn some of the best practices for ETCs in cold climates, such as:
