Thermosiphon solar collector provide heat through a efficient copper coil. It's different from normal water heater. Water can be put directly in collector, but adding heat coil. When cold water goes through copper tube, it l be heated by heated oil. The length of copper tube is 45-60.There's no water entering such kind of collector so that it can avoid corrosion and rust. Thermosiphon solar collector is not allowed to be connected directly with pressure water.
　　 Tank installation is subject to local area. Circled thermosiphone solar collector system is suitable for single or multiple solar system. For example, family solar water heater, solar water swimming pool and solar water furnace system. It's the best choice in cold area or poor water quality area.
