It
NEVER Freezes where I live
|
If
you are willing to drain the system while nightly temperatures
might go below 38ºF the SW
system (2 or 3 panels) or the EZ
system (4 and more panels) are fine. Our
warranty does NOT cover freeze damage so it is important to
drain the system.
For
year round operation with complete freeze protection the GH
system is necessary. The heat transfer fluid is included in
the kit and you can determine the level of freeze protection by
how much you dilute it. Freeze protection down to -30°F
is possible. The heat transfer fluid DOES NOT touch or get mixed
into your water supply.
