Residential Solar Thermal - Water Heating
The main components of the Power Save Solar Water Heater Drain-back System is 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 Drain-back 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 Drain-back heat transfer tank to the collector on the roof where it is heated. It is then pumped back to the tank where the transfer of heat to your home's hot water tank takes place (we offer additional 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.
A long history of reliability, our drain-back 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 Drain-back 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 drain-back 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 wit distilled water in a closed system loop.
Our system meets all 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.
