Hello group,
I noticed a potential regression between V7.2 and V8 regarding the HTML output table generation. I could reproduce the issue using the following example file: SolarCollectorFlatPlateWater.idf.
The issue occurs in the Report: WaterHeaterReportMonthly relative to a storage tank which is connected to a solar plant. The very last column of the report should represent the energy coming from source side. This works perfectly in V7.2 but in V8, the column is set to 0 with the following error in the header: WATER HEATER SOURCE ENERGY [Invalid/Undefined].
