Solar Drainback Systems
A drain back-able evac tube system might excite me. I hate the concept of dumping"free" heat with powered, or even un-powered devices :) DB does make a lot of sense for large seasonal arrays. Overheat and freeze protection, combined with better heat BTW - we only install drain back solar systems and have been since 1982.
Solar Drainback Water Heating System
They''ve basically boiled down the solar drainback system to one tank, one controller and one pump. It''s that simple. As with all drainback systems their freeze protection is attained through gravity. When the solar collectors are hot enough to heat the tank, the differential controller turns the pump on and water flows from the tank and back

SuperStor Solar Drain Back Tank
The SuperStor Solar Drain Back Tank is designed to stabilize and protect solar thermal systems. A drain back tank allows all the water from solar collectors and related piping connections to drain into the tank reservoir, protecting the system from both freezing and overheating. Drain back tanks are ideal when designing solar thermal systems
Drainback solar thermal systems: A review
A drainback system corresponds to a "solar thermal system in which, as part of the normal working cycle, the heat transfer fluid is drained from the solar collector into a storage device when the pump is turned off, and refills the collector when the pump is turned on again" (ISO, 1999). This unique attribute to empty the collectors and to
auroFLOW PLUS
With a drainback system the fluid is protected against stagnation and freezing as it is automatically drained, by gravity, to the solar station and as soon as the need for heat ends. The regulation of the solar system is done quickly and easily, and all information on its operation can be viewed on its digital back-lit display.

Part II—Drainback Systems
Solar Hot Water A true drainback system is an unpressurized closed loop. Some early drainback system designs incorporated vacuum breakers and automatic air vents in the collector loop. These features are mistakenly borrowed from the open loop, draindown system design. This atmospheric venting of drainback systems
The drainback system
The drainback system. There are 2 basic types of solar thermal system - Drainback systems and pressurised solar systems. If you are familiar with heating systems, a good way of comparing them is a drain back system is comparable to an open vent system, and a pressurised system is comparable to a sealed system. Drainback systems
