Radco Solar DBHX 6000 Series Drainback Heat Exchanger

Operate a solar water heating system by transferring solar energy to a storage water tank.

The Radco DBHX 6000 series drainback systems have these strengths:

* Allows most any solar collector and water storage tank to become a drainback system.
* Modular design translates to lower labor costs for installation and less space requirements for installation.
* Provides automatic and fail-safe freeze protection.
* Works well in most climates.
* Power is not required for the drainback freeze protection to work.
* Does not need propylene-glycol to protect from freezing temperatures.
* Low maintenance - No need for propylene-glycol or rust-inhibitor fluids translates to less maintenance requirements
* The closed-loop to solar panels protect the collector's fluid passages from mineral build up caused by "hard" water --where water contains an excessive amount of dissolved minerals.
* SRCC approved designs.

These systems are Performance Certified when installed to SRCC OG300 Specifications and tank sizes. When properly installed and maintained, these systems meet the minimum standards established by SRCC. The SRCC certification does not imply endorsement or Warranty of this product by SRCC.

Available in various sizes and configurations (with/out auxiliary tank, etc). The unit's efficiency will vary based on the configuration. The specifications below are for a 65 gallon model with an electric auxiliary tank.
