Closed Loop Solar System
A Closed Loop Solar System
A Closed Loop Solar System works by having fluid, either glycol or water/glycol mix circulated through the solar panels and down into the cylinder.
The heat from this heat mix is then transferred to the water waiting to be heated in the cylinder, via a heat exchange unit. The fluid then leaves by being pumped back to the solar panels to be heated up again and the cycle continues. The glycol/water mix does not mix with the water in the cylinder.
