ARCHITECTURAL SERIESSolar Hot Water Tanks

The main components of the ARCHITECTURAL SERIES Solar Hot Water Tank (Drainback System) are a water storage tank, a smaller tank that stores heat-transfer fluid (usually water), a solar panel collector that captures heat from the Sun, and a heat transfer system that transfers heat to the water tank.

HOW OUR ARCHITECTURAL SERIES 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 solar hot water tank (we offer storage tanks tailored to your household's needs) for you to use.

The heat transfer portion of the system is only filled with the transfer fluid when the pump operates. When the pump is not on, water will drain by gravity out of the system and back into the heat transfer tank. This leaves the collector empty and full of air at times when freezing temperatures could occur.

  • 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 works with distilled water in a closed system loop.
  • 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.
