Antifreezing Solar Heating Systems (Active-Closed Pressurized Systems)

Cold climates demand more complex systems. Batch/ICS systems are clearly inadequate in freezing conditions, and thermosyphon solar systems involve some limitations.

One of the most popular solutions for freezing climates comprises a relatively complex system with an antifreezing fluid (glycol, usually), a differential controller, an expansion and a storage tank, and a heat exchanger and sensors and valves.
