Locate drain at low point of solar thermal piping. If no low drain was installed use the second valve on solar pump station. Connect second hose. If the system is not equipped with a drain valve at the low point(s), consider fi tting one for future servicing while the system is off line. 5.
I fitted a solenoid valve to bypass the circulating pump so that there will be some circulation by convection, however, the temperatures still rise above 100C and the steam hammering persists. To mitigate, I fitted a relief valve to the solar flat panel water heating system at the outlet end. Please see the attached image.

In solar thermal applications, drainback systems (DBS) provide simple protection against overheating and freezing of the applied heat transfer fluid (HTF), guaranteeing the reliability of the system in general. For a safe operation, three repetitive operating stages are necessary, namely filling, operation mode and draining.

Let''s talk about how the automatic drain valve works. It works by allowing the condensate to flow to the valve''s condensation reservoir. Once the liquid in the condensation reservoir reaches to a point that the float lifts off the seats, it sends control air pressure to the pneumatic piston so that the ¾ ported ball valve is opened.

The draining process Once the solar controller turns off the pump (s) or in case of power failure, the draining process occurs automatically. It has a protective function for the DBS, and implies the draining of the HTF from the upper part of the hydraulics into the drainback volume.
Operating modes of the drainback technology are systematically evaluated: filling, operation, and draining. Hydraulics of drainback systems are described. Variety of components and associated requirements are presented. Although solar drainback systems have been used for a long time, they are still generating questions regarding smooth functioning.
The only differences are other operation conditions and the control strategy of the pump. When the pump is stopped, a gravitational draining process occurs automatically. The draining has a protective function for drainback solar thermal systems. Empty collectors exclude both overheating problems during stagnation and frost damages in cold periods.
Drainback systems as an efficient and safe solution for solar DHW installations: practical experience. In: Proceedings of the ISES Solar World Congress 2011, Kassel, Germany, pp. 621–632. NABCEP, 2012. Solar Heating Installer Resource Guide. North American Board of Certified Energy Practitioners, Clifton Park, New York, USA.
Automatic valves are mounted at the inlet of each collector row. A successive opening and closing of the valves during the start of the system ensures the complete filling of each row separately. Thus, a successful filling of the entire DBS is achieved avoiding oversizing the pump capacity.
