The energy, economic and environmental analysis of a solar heating system with seasonal heat storage integrated into a district heating system based on natural gas boiler was performed. The solar collector field has a surface area of 8720 m2 and the pit seasonal heat storage has a volume of 10000 m3. This system covers 79% of the total yearly heat demand of the 15 multifamily buildings with 1500 inhabitants. The total system investment cost (2974100 €) may be recovered in about 17 years. The environmental impact of solar heating system integration is the decrease of CO2 emission by 79%.
