The water tank that acts as a storage system in a solar water heater is used as a back-up system for the solar air collector. Generally, a field of solar collectors is used to respond to thermal energy needs expressed by a consumer for a given purpose (heating, drying, etc.).
Types of Storage Tanks | Solar365
Tanks without Heat Exchangers. The most common type of hot water storage tank used in solar thermal systems comes without a heat exchanger. These tanks are normally made of steel or fiberglass, are insulated and connect to the water supply, the drain and the heat exchanger. That may sound familiar, and for good reason: a standard water heater ...
What are Solar Thermal Storage Tanks? | Solar365
The tank is surrounded by foam insulation, on the outside of which a light-gauge steel jacket sits, to protect the insulation. Basically, it looks just like any standard water heater. Higher-quality tanks usually come with an anode rod to prolong their life even further. This is a special metal rod, also called a "sacrificial" rod, which screws ...
