SOLAR LOOP

The “Solar Loop” is where solar energy is collected by solar collectors, turned into heat, and then
pumped where it needs to go in order to fill our needs. It is a “closed” system consisting of solar
collectors, a plumbing mechanical package and one or more heat exchangers. “Closed” means
that the system has its own working fluid that stays in the system and is not removed except for
maintenanceWhen the sun shines upon the solar collectors, the solar energy heats an antifreeze solution.
When the solar heated antifreeze solution is warm enough, a circulating pump turns on and
circulates the warm antifreeze solution to one or more heat exchangers, where the heat energy
is put to a use such as the production of domestic hot water, or space heat, or some other use.
The antifreeze solution then returns to the solar collectors to be reheated.
