Solar fluid maintenance in solar water heating system

Solar system for water heating can work without any maintence work.Only thing that must be taking care of is solar fluid.In  system for water heating we use Glycol/water mixtures.During cold weather it esential to check freezing point of your solar fluid.
It should be at least -20 celzius.In some system you can drain fluid during winter when solar system is not in use.This winter in Europe temperatures can be even -30 C, Glycol freezing point can measured using  Glycol Antifreeze Pocket Tester.Be aware some testers that are used for cars antifreeze wouldnt work with Glycol fluid.
