- The sun heats a non-toxic, freeze-proof solar fluid (a
combination of propylene glycol and water) in a solar collector on the roof (A).
- A Sensor (B) detects that the solar fluid is hotter than
the water in the hot water tank.
- A pump in the Solar Station (C) pumps solar fluid
from the collector to the hot water tank.
- The solar fluid flows through a pipe coiling inside the
hot water tank (D), and heats the water in the tank.
- The hot water is available for use in the house.
- The solar fluid is pumped back up to the collector,
where it is once again heated by the sun.
