Pre-Heated Solar Water Heating
Features  of Pre-heated Solar Water Heater
1.This equipment utilizes the pressure of  the tap water to produce hot water with constant temperature, which is safer  and more comfortable.
2.Our pre-heated solar water heater can be  installed in flat roof as well as inclined roof.
3.The water can be heated rapidly.
4.This solar water heating system consists  of solar storage tank, make-up water tank, solar thermal collector and support.
Description
  The pre-heated solar water heater is  equipped with a copper coil inside the tank as the heat exchanger. It is  immediately used for heating when water goes through the coil pipe. Clean and  without sludge, this solar water heating system is  applicable to the places where the water quality is relatively poor. 
  According to different configurations, our  pre-heated solar water heater can be divided into economical version and  advanced version. Equipped with electrical heating system and controller, the  advanced type solar water heating system can fully fulfill your requirements.
  While the economic pre-heated solar water  heater adopts vacuum pipe to achieve direct heat transfer, featuring in high  thermal efficiency, free maintenance and low use-cost.
Maintenance  and Notes
  1.You should replace the broken pipe  without delay. Otherwise it will affect the heat efficiency.
  2.The pre-heated solar water heater should  be used frequently.
  3.If this solar water heating without  water, it can not be insolated for a long time.
  4.The bearing capacity of the roof should  be considered when you choose the pre-heated solar water heaters.
Payment and Transportation
  1.The solar water heating system can be  paid by T/T and L/C.
  2.We transport our pre-heated solar water heaters by sea with carton packing. The sample  adopts wooden case.
