1. Model Validation

2. -Air lock caused flow restriction, elevated temperatures -Excess energy lost to boiling and higher temperatures -Underperformed model predictions

5. Warmup Characterization

6. When conditions are such that after passing through the heat exchanger and the lower 2/3 of the collector the water has not yet reached temperature, the valve will restrict flow. This appears in the data as an oscillating temperature at the valve, as well as a “cycling” of output.
