Vacuum tube copper coil pressurized solar water heater working principle

  All the parts are the same to non pressure solar water heater, except adding a heat exchanger copper coil inside big tank. When cold water flows into the copper coil, it absorbs the heat of the water in big tank via the copper coil, to get hot water.  It can bear the pressure from tap water (6 bars), so there will be a more comfortable shower. Meantime hot water that we use not transfer in solar tank directly, the hot water is more clean and healthy.

 

  This type, we need to install auxiliary tank, it just makes up some water into tank in case evaporating from air vent. Because we do not use water from the big tank, the tank just work as heat source to heat water inside copper coil. So after days or months, water will be less and less, auxiliary tank will auto feeding water into the big tank

Feature

1. use in any time: it adopts advanced design idea and integrates with high efficiency preheated patent technique. So it can warm the cold water rapidly when it flows through special pipe. It can overcome the short of traditional solar water heater, such as slow heating, long waiting time.
2. more capacity: we adopt special exchanging heat mode, it avoids mixed effect. So cold water can be heated at any time.
3.  strong hydraulic pressure: the hydraulic pressure is same as tap water. It is very suitable for tired person.
4. economical and environmental protecting: there is no pollution when it is working since it depends on sunshine, green and economical
5. easy operation: it can supply water automatically, you can take it easy and enjoy good time
6. fashionable: the appearance is fashionable and it can great integrate with your fitment.
