Hi John, perhaps you are intrested in this article I wrote: DIY_solar_thermal_collectors, linked from the article: AT CAD Team Also, I also received a batch heater design a while ago which you could use, i'll forward it if you are intrested; it's a bit better than your batch heater, although my design still tops it; however my design is less conventional and perhaps more difficult to built.
