Compact Vacuum Tube Solar Energy Geyser

Specification: Pressurized solar water heater(thermosiphon) provide energy and get hot water by a efficient coppper coil fixed in water tank. Different from other common solar water heaters, this type could be used pressurized. As water in tank can store energy, when cold water goes through copper coil, it could absorb heat from water in tank. The copper coil is20-60 m long. Tank installation should be according to local condition. Thermosiphon solar water heater system is suitable for family, swimming pool, solar water furnace system and floor heating. It is suitable in areas with cold weather and bad-quality water. It could be used as pressurized system, with much lower price than solar water heater with pressurized water tank.
