A great way to utilize renewable energy and reduced money on your electricity expenses. However, the material selection of these systems is vital for optimal thermal performance. In this article, we will discuss the key materials used in solar water heater water heaters and their characteristics.
The pick of material depends on several factors such as the heating rate inside the tank, the flow rate of the fluid, and the desired thermal performance of the system. The most common materials used in solar water heaters are glass, and copper.
Glass is widely employed in solar water heaters due to its transparency, durability, and resistance to corrosion. However, it can be heavy and may require additional support. The glass tube is typically coated with a layer of metal oxides to minimize heat loss and increase efficiency.
