Manifold with  Heat Pipes in Vacuum Tubes for High Pressure Solar Geyser

Solar Geyser +

Heating panel =

Close coupled solar heating system 

The manifold with 47mm diameter tubes is suitable for South Africa conditions. It can be used in either a direct or indirect solar water heating system. Its pressure rating is 6 bar (600 kPa). The manifold and mounting brackets can be installed on a suitable roof and the geyser placed inside the roof. If the geyser is above the top of the manifold, the hot water will circulate on its own into the geyser. If the manifold is placed above the geyser, a circulating pump is required. 

ENSURE THAT THE GEYSER, FRAME AND MANIFOLD ARE SECURELY FASTENED TO THE ROOF.

Safety Precautions  It is recommended that gloves are worn when assembling the mounting panel as the stainless steel components have sharp edges.

Installation Instructions for heat pipes

 THE HEAT PIPE is the active heating element. It is inside a vacuum tube that absorbs all the heat, but emits very little heat. This makes the collection of heat very efficient.

NOTE – KEEP THE HEAT PIPES IN THE BOX UNTIL YOU NEED THEM, AS THEY ABSORB HEAT FAST WHICH MAY PREVENT THE HEAT PIPE FROM ENTERING THE MANIFOLD

Place rubber cap on end of Vacuum tube

Apply Heat Paste to Top of heat Pipe

Apply Dishwashing mixture around the top of the Vacuum tube below the top of the Heat Pipe

Insert Vacuum tube into the Manifold hole

Tighten Clip around rubber cap – DO NOT OVERTIGHTEN    

1. Inspect the Vacuum tube to see that it is still silver and that the vacuum is intact.
2. Place rubber cap on end of Vacuum tube

   

3. Apply Dishwashing mixture around the top of the Vacuum tube below the top of the Heat Pipe. This allows the glass tube to slide into the rubber holder easily.
    

4. Apply Heat Paste to Top of heat Pipe. The heat paste allows better heat transfer from the heat pipe to the manifold and to the water
   

5. Insert the bottom of the tube through the Clamp at the bottom of the manifold
   

6. Insert Vacuum tube into the Manifold hole by rotating the tube slowly and pushing it into the manifold. The dishwashing liquid makes this easier than if it were dry.
    

7. Tighten Clip around rubber cap – DO NOT OVERTIGHTEN   - This can cause the glass to break. The clamp only needs to hold the tube in place, it does not need to grip it tightly. 

   

8. Continue until sufficient tubes have been added to complete the manifold.

When complete and installed on the roof  your panel will look something like this 

The plumbing connections are 22mm copper and are rated to 6 bar pressure.

The left hand side is connected to the solar geyser cold side (sometimes marked - "To Solar Panel") and the right hand side to the solar geyser hot side (sometimes marked - "From Solar Panel"). With Duratherm solar geysers the left hand side is connected to the solar geyser blue port and the right hand side to the solar geyser red port. 

For Kwikot, Solardome, Suntank, Tecron and Xstream geysers follow the labelling on the geyser itself.
