Comprehensive analysis of hot water tank sizing for a hybrid solar-biomass district heating and cooling

Different sizing criteria for thermal energy storage (TES) has been developed through the years, regarding specific situations for thermal solar panels, which tend not to be representative for new, more complex systems, in which heating and cooling are provided through using also solar thermal collectors. This article aims to provide a simplified and elegant solution for future tank selection in a more variable combination of technologies, through the use of parametric simulation and an inhouse developed methodolgy.
