How it works:

The heat pipe solar collector system uses pressurized vacuum tubes which transfer solar energy to a main heating pipe. 

The vacuum tubes contain a copper pipe which is filled with liquid. When the pipe is heated, the liquid inside it vaporizes

 and rises up to the condenser at the top, transferring the heat to the water passing through it. 

The cooled vapor then becomes liquid again, refilling the tube, which restarts the process.
