DBX© Drainback Heat Exchanger Tanks:


DBX tanks go one step further with the Heat Exchanger inside the drainback tank. This allows for additional savings by purchasing only a solar storage tank or even using the existing water heater.

Offered in 10 and 15 gallon sizes, the standard DBX tanks are designed for mounting on top of the solar storage tank or water heater.

For more system customization, DBX tanks are available with different heat exchanger sizes to suit the amount of collectors used.

The 10 gallon is offered with either a 3.4ft² or a 6.2ft² surface area heat exchanger. The 15 gallon is offered with a 6.2ft² or a 9.8ft² surface area heat exchanger.
