Heat  Pipe  High  Pressurized  Solar  Water  Heater (compact  pressurized  solar  water  heater)  SF-1800-58-24-CSP  with Aluminum Alloy for Slope Roof SUS304-2B food grade stainless steel series


240L Compact Pressurized Solar Water Heater With 58mm * 1800mm Vacuum Tube



Sunfield high pressure standing alone model is a new type of solar water heater which adopts advanced heat pipe and all glass vacuum tube technology. The available size of the tank ranges from 100L to 300L.

Heat pipe high pressurized solar water heater Compact pressurized solar water heater

This kind of solar water heater is comprised of three parts: pressurized water tank, heat pipes (solar collector), and bracket (support).
SUS304-2B  food  grade  stainless  steel  for  inner  and  outer  tank,  nontoxic, anti-corrosion

Aluminum alloy reflector helps to raise the heat absorbing efficiency.

Heat pipe  (compound heat pipe) is comprised of three target vacuum tube, copper heat pipe, aluminum fin (s), silicon stopper, and stainless steel gasket. The choice of copper heat pipe is based on the temperature (climate) of the area where  the  solar water  heaters  are  used.  Normally,  the  main  points  are  the thickness and the freezing resistant feature of the copper heat pipe.


Bracket (support): stainless steel

It has the following features:

1)  It can start work very fast.

2)  It directly connects with tap water.

3) Pressurized tank, working pressure 6 bar, Max resistance 12 bar.

4) Reliable and efficient twin-glass solar tubes

5) Copper heat pipes are for rapid heat transfer. No water goes through the
tubes, so that the system can still work well in the winter. Freeze protection.

6) With aluminum alloy, better efficiency.

7) Easy plug-in installation.

8) Easy maintenance.

9) Stable solar conversion during the day.

10) Ideal for home applications.

Work principle:

1) Highly efficient vacuum tube absorbs heat from sunlight and heat pipe transfers heat to the condenser end of itself. The condenser indirectly contacts with water through a copper cap and it boils water by releasing heat gained from vacuum tube.


2)  If the water temperature is more than 99 Celsius degree, and pressure rises to more than 6 bar, the TP valve will release automatically.

3)  The electrical heater can be operated for auxiliary heating equipment. For compact system, we recommend to use 1.5KW electrical heater.
