Solar Hot Water Heaters
RADCO Drainback Solar Hot Water Heating Systems bySun Systems, Inc. Learn more »
The main components of the RADCO Drainback System include:
- water storage tank
- smaller tank that stores heat-transfer fluid (usually water)
- solar panel collector that captures heat from the Sun
- heat transfer system that transfers heat to the water tank
How the RADCO Drainback System Works
- A heat-transfer fluid, usually distilled water, will circulate through the system when the collector’s solar sensor determines that there is a usable amount of heat from the sun's rays
- The fluid is pumped from the Drainback’s heat transfer tank to the collector on the roof where it is heated
- It is then pumped back to the tank where it transfers its heat to your home’s hot water tank (we offer storage tanks tailored to your household’s needs) for you to use
Long history of reliability
Our drainback system can operate for years without requiring you to perform any maintenance. A solar water heater can work just like any other appliance in your home. It "just works"
Freeze protection is part of the basic design of our Drainback System
All the water drains out of the solar panel and any exposed piping whenever the pump is not active --such as at night, when it is an inefficient solar heating day (freezing temps or heavy cloud coverage) cold during the day, or there is an electrical power outage, draining by gravity back into the drainback heat transfer tank
No costly, high maintenance transfer fluid needed
No need to periodically flush and fill the system with expensive, new anti-freeze fluids, instead the system works with distilled water in a closed system loop
Tax Credits and Rebates
The systems meets requirements to be a SRCC OG-300 certified configuration, which in many markets means that this system will be eligible for tax credits and rebates for most solar tax programs
