4. System hydraulics expansion vessels
The collectors can be operated with a high specific throughput (so-called High-
Flow). Advantages: The collector is well cooled = high collector efficiency level,
low heat losses at the flow line. Disadvantages: High pressure drop = powerful
pump, large pipe cross-sections.
Throughput: High-Flow (90 l/h x coll), ANRO (45/55) 20 °C
