300L Sperated Pressurized solar  panels heating water

How it works:

Separated pressurized solar panels heating water is pressurized solar water heating system ,main absorbing collector adopts flat panel solar collector with blue titanium coating. This solar system is active by circulation pump which control by workstation.Flat panel solar collector collects the solar energy and transfer it into heat energy to heat the solar system and storage the hot water in storage tank.

solar panels heating water gets  solar energy  by flat panels solar collector and exchange the heat to tank by heat exchanger.With the active working of circulation pump ,the water become hotter and hotter.

Vod solar panels heating water tank works long lifetime cause its high quality design for material and restrictly pressure test before forming.

   Interior  tank adopts SUS304-2B food grade stainless steel 1.5mm.

   exterior tank adopts color steel with high zinc  0.45mm

  Tank insulated with  high density polyurethane integrated foam 50mm,keep hot water more than 3days.

   Instead of the copper coil, we choose flexible wave stainless steel 304 as heat exchanger. Diameter 12mm and thicknesss 1mm,length 15m each coil. Wave design of the pipe enlarges the heat exchanger area.

  System working pressure:6Bar

 Solar Collector with white aluminum alloy case,strong in thickness 1.2mm.Sealed with EPDM strip against high temperature and long lifetime more than 20years.

A reasonable air vent hole is designed for release water vapor to protect absorbing board.

 Solar Collector in Blue coating imported from German,2sets flat panel  solar collector , size 1000X2000mm,blue coating.

Intelligent controller system of the workstation  has several models for control the solar panels heating water working .

It can work with electric heater as backup .Or with gas boiler, heater boiler and other heating equipment as backup through additional copper coil.

To choose a right solar panels heating water ,we give some suggestion for your understand.

We divide three solar panels heating water system by heat exchanger numbers.

A: Storage Tank without coil.It is cheapest solution of all three types. Flat panel request for anti-freezen fluid or working with water under hot area.So working under this system without coil , the tank directly exchanges the hot water with solar collector by circulation pump which control by controller. It requests to work under temperature above 0 degree.

B: Storage tank with one copper coil, this coil is for the circulation between solar collector and water tank and circulation pipeline usually filling with anti-freeze fluid (glycol for example) as heat exchange media.

C: Storage tank with two copper coils: one for collector and tank circulation, other one for heating equipment or space heating   (such as connect to gas/electric boiler , and for floor heating system). Solar circulation also request fluid as heat exchanger media.

First we should fixed which type system would suitable for you.

Then we select right capacity for your house,we offer a large range capacity from 100L to 1000L for resident house use.If you want to have a bigger size more than 1000L,we will give a detail design for you.

To choose the right type system and parts:

We will suggest you to tell me the installation location, any existing heating equipment. And then we will make a design for you.

For the system usage you may need the following parts:

1.    Air vent: to release the air in system

2.    Expansion tank: balance the pressure of system

3.    Controller for system type one (tank without coil): brain of system

4.    Workstation (suggestion for tank with coils): brain and safety device

5.    Thermostat valve （for a constant hot water）:easy hot water mixing

6.    Pipeline and insulation

7.    Fittings (for pipeline and system parts)

8.    Solar bolts and hooks (for solar collector fixing)

9.    Heat exchanger (for outside tank heat exchange)

10. Safety valve

11. Filling valve (easy filling fluid)

12. Motorized valve (change or close/open energy flow way)

13. PT valve

14. One-way valve

15. Magnesium bar
