Indirect Solar Storage Tank

The Indirect solar water heater is decorated with a copper tubing (120' of 5/8" I.D. tube) wrapped around and secured to the tank. Its double wall, vented design is for positive leak detection and is foamed in place with R-Foam for high efficiency.  This solar heat exchanger storage tank is designed for closed loop solar systems.

In a typical solar water heating system, an Auxiliary (A2) relay can divert surplus heat to another tank or operate an auxiliary heater for boosting the tank temperature. The advanced differential controller should be used for the above configuration.
