Direct/Open Loop The domestic hot water is
heated in the collector
Passive
No pumps
Indirect/Closed Loop
• A solar fluid is heated in the collector
and a heat exchanger is used to transfer
the solar heat to the DHW
Active
• Involves pumps

System Types
Open loop systems have limited use in northern climates,
including:
• Integrated Collector Storage (ICS)
• Flooded systems
• Recirculation systems
• Draindown ystems
Active, closed loop systems have proven most appropriate for
northern climates, including:
• Pressurized glycol systems
• Drainback systems

System Design Considerations
Freeze Protection
• Northern climates have extended periods of freezing
weather
• Almost all climates in the US freeze periodically or
occassionally
• Systems either uses a solar fluid that will not freeze or
make sure that water is not exposed to freezing
conditions
Scaling
• Hard water can cause reductions in system efficiency
and can lead to failure
