This paper presents a system simulation and parametric study of the most standard Seasonal Thermal Energy Storage System (STES) configuration, hot water tank STES system for district heating. This configuration is detailed is modeled in detail in TRNSYS, a dynamic simulation program, in order to integrate the different sub-systems (storage, generation and consumption) and optimize the overall performance of the whole system for four different climate zones Southern (Madrid), Northern (Stockholm), Central (Amsterdam) and Eastern Europe (Warsaw). These locations have been selected as reference locations in order to realize simulations and get throughout results. The aim of the chosen configuration is to cover the required space heating demand and domestic hot water preparation (DHW) of 50 retrofitted dwellings (district heating network) for each location and analyze the different alternatives concerning economic and technical aspects.
