400L Split solar hot water heating system

Simple introduction:

capacity tank 400L with 3pcs 2squre meter size flat plate solar collector ,complete with workstation which control system installed.

Our solar hot water heating system adopts the blue titanium coating absorbing board flat plate solar collector.

Detail information of the flat plate solar collector as below:

Absorber :

core material:copper pipe and aluminum steel.

jointing： Ultrasonic welding most advantage technical 

Efficiency :absorptivity more than 95% and emissivity less than 20%

Vod solar hot water heating system adopts the high quality material for our  solar hot water heating system tank.

²  Inner tank: SUS304-2B food grade stainless steel 2mm ,400L

²  Outer tank :color steel 0.45mm size : Φ700 mm*1560 mm

²  Tank insulation layer: high density integrated foam polyurethane 60mm

²  Copper coil :16mm/1mm 15meters each coil ,copper is currently common and best metal heat conducting media.

²  Working pressure:6Bar

Our workstatiion is equiped with filling valve ,safety valve,intelligent controller, expansion tank, pressure guage and circulation pump for commond the solar hot

water heating system working effecienctly.

It helps to save a lot installation jobs,filling valve can filling anti-freezen fluid easily . Safety valve makes sure safety running of system.Pressure guage can monitor

the unusual pressure in system, expansion tank plays the role of balancing pressure. Circulation pump helps active the solar hot energy heat exchange. Most

importance part is the intelligent controller which is the brain of the system control the system working and display all main data on tank temperature,solar collector

temperature and output the signal for working for electirc heater or boiler working.

To get a easy understand for running the solar hot water heating system,we should learn the working principle first.

Split solar hot water heater system is working by main three parts hot water tank, solar collector and workstation.It is closed-loop system. Solar collector generates  heat power by absorbing solar energy. It is generator of system. The storage tank plays a role of  heat storage. The workstation is the brain of solar water heater. The circulation pump pushes the solar collector to storage tank when the temperature difference between solar collector and storage tank reaches the setting valve.

In short concluded, there are three working systems which are divided by tank design： 

One: Tank without coil. Circulation media is water from tank. Solar collector and tank directly exchanges heat by circulation water between them. It is easy and economic solution.Please note: if the solar collector is flat panel type,it can only work under hot place for anti-freeze purpose of this situation.

Two: tank with one copper coil, this coil is the heat exchanger for solar collector to conduct the heat to storage tank. The circulation fluid adopts anti-freeze glycol.

Three: 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.

According your demand and real situation, you can study above three solar hot water heating system ,and make a decision to choose which one is best for your work. 

Sure ,the nessissary components for installation the system is request. 

Following is some parts you may apply to solar hot water heating system.

1.    Air vent: for a security suggest installed beside the solar collector,once the solar collector system is big .

2.    Expansion tank choose depends on the system capacity ,the bigger system ,the bigger size you should take.

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

4.    Workstation (suggestion for tank with coils)

5.    Thermostat valve （for a constant hot water） 

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
