Climate To determine the right type of system for you, we first need to know what type of climate you are living in. The most important factor is how cold your area's worst winter months were within the past 20 years.
FACT: Believe it or not a proper solar hot water system is designed to work year-round.
Our run-by-the-sun “Skyline5”closed loop systems are perfect for areas that freeze.
They offer “worry free” COMPLETE FREEZE PROTECTION when properly installed.
92% of the U.S. is considered a hard freeze climate.
Our run-by-the-sun “Skyline3” open loop systems are good
for areas without any freezing conditions at all.
Designed for Tropical areas like Florida, the Carribean, or Hawaii.
These “Skyline3” systems can also be used with light-freeze
protection for areas WITHOUT hard freezing conditions but with
occasional light-freezing conditions and areas where the temperature rarely
goes down to 30°F with NO Hard Freeze.
This light-freeze option is for areas like Southern Florida, and some coastal California areas like zones6/7 in San Diego.
No-Freeze(Open Loop) Freeze Warning: Due to the high level of variability, open loop system collector
absorbers cannot be warranted against freeze damage.
