MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202617084725 A) filed by Neoperl Gmbh on July 10, 2026, for Thermosyphon Solar Water Heater With Automatic Backflush.
Inventors include Harrison, Stephen James; and Stinson, Benjamin R..
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: A thermosyphon solar hot water heating system specifically designed such that it incorporates an integral, automatic backflush configuration. When hot water is drawn from the system, an automatic backflush valve redirects cold "mains" water through the system's solar collector(s) in a flow direction that is opposite to the normal buoyancy-driven flow direction that occurs during solar heating (i.e., "charging"). This backflushing action is completed passively when heated water is consumed for domestic use and does not require other user intervention. The routine introduction of cold water through the solar collector during the backflush, reduces the formation of mineral deposits in the solar collector's flow passages and the reverse flow scours the interior surfaces of the solar collector's flow channels such that the potential of scaling is significantly reduced.
