A superior way to harness renewable energy and minimize money on your utility bills. However, the choice of materials of these systems is crucial for optimal thermal performance. In this article, we will analyze the key materials used in solar water heaters and their characteristics.
The choice of material depends on several factors such as the heating rate inside the tank, the fluid circulation of the fluid, and the required thermal performance of the system. The most common materials used in solar water heaters are plastic, and aluminum.
Glass is widely employed in solar water heater water heaters due to its transparency, durability, and resistance to corrosion. However, it can be heavy and may require extra support. The glass tube is typically coated with a layer of metal oxides to reduce heat loss and increase efficiency.
