Solar hot water heaterComponents

Solar thermal collector (vacuum tube with copper heat pipe)Pressurized water tank(includes P/T safety valve, heating element, magnesium bar, heat exchange copper coils)Working station (includes expansion vessel, circulation pump, digital controller, piezometer )/ integrated working stationRelevant parts for connection

Details

Expansion vessel

 As the heat transfer fluid (water and glycol ) in the pipeline is heated by sunshine, it expands. In this closed-loop system, the expansion vessel allows the fluid to safely expand by compressing the air and locking it inside a bladder or diaphragmin.

Working temperature: -10 to 99 degree centigrade

Max working pressure: 10 bar

Circulation pump

1.Brand: Wilo

2.Suitable fluids: water/glycol mixture, max mixing ratio 1:1, mixing ratio required for hydraulic collector above 20%.

3.Manual 3 speed control

4.Fluid temperature range: -10 to +110 degree centigrade

5.Max working pressure: 10 bar

Intelligent controller

1.Power supply: AC220V/110V, power consumption: <5W

2.Accuracy of testing temperature :±2°C

3.Range of testing temperature: 0-99°C

4.Power of controllable cycle pump: <800W

5.Power of heating element: 3000W

6.Three inputs and two outputs

Pressurized Water tank                                                                    1. Inner tank material: SUS304-2B food grade stainless steel 1.2-2.0mm thickness2. Outer tank material: imported pearlescent white color steel with 0.6mm thickness.

 galvanized color steel 0.4mm thickness

3. Material of heating preservation: 50-60mm Polyurethane.4. copper coils/tank: 0,1,2

5. water tank capacity: 100L-500L6. Pressure: 6 Bar 7. Heat preservation: Water temperature in tank descend 3°C for 24 hours (when water not in use)

                                    

Vacuum tube solar collector

1.Vacuum Tube: all glass vacuum tube with heat pipe

 tubes: Φ58*1800mm 

tubes/set:10/15/20/25/30/40/50      

Hail resistance: 25mm  

2.Heatpipe:copper,length1700mm; condenser side  Φ14mm, length 70mm       

3.Frame material: Quality aluminium alloy/ SUS304 stainless steel/ Galvanized steel

Feature

  1. Perfectly concordant with the architecture appearance: Solar collector can be installed on roof, balcony or wall of flat, sloping or vertical sides while water tank seperate from the solar collector that can be install in the room.

  2. Anti-freezing, more suitable in cold areas,fast start up on cloudy or rainy weather. Realize hot water availablility regardless of time and weather.

  3. No water inside vacuum tubes, breakage of some tubes will not inflence the ordinary operation of the whole system.

  4. Water does not flow in vacuum tubes, that preventing the collectors from freezing and bursting in cold climate.

  5. This type of solar water heater works with high pressure, so do the water it produces which makes bathe more comfortable.  6. Equipped with magnesium bar which improves the water quality and lengthens the lifespan of the storage tank.

  7. 24 hours water supply on condition that pipeline is working.

  8. Works well in the cold place even -35°C
