ESharp, how is it going with your project, all these years later? Is it still working?

I am researching the drainback principle. Where I have built a few systems, most of every system is a closed system, with anti-freeze (glycol). They do normally NOT drain back.

I am working on combining various technologies, to take solar thermal to a new level of both efficiency, simplicity as well as reliability (and less maintenance)
