Long-term performance estimations were performed on a nonstandard domestic solar water heating system by f-Chart, interactive F-Chart software, and φ¯,f-Chart methods. Results of estimations were compared to gain insight of their applicability. Results from F-Chart software and f-Chart agree well and are greater than those from the φ¯,f-Chart method. Energy dumping should be given thorough reconsideration for the refinement of f-Chart and F-Chart software.
