A solar collector meets the hot water needs of a family for 7 months, excluding 5 months of the winter season. This collector provides hot water at an average temperature of 55°C and an average cold water temperature of 16°C. The family uses an average of 14 tons of hot water per month from the solar collector, and in winter, hot water is provided by an electric heater. Since the unit price of electricity is 0.85 TL/kWh and the efficiency of the electric heater is 91%, calculate the annual electricity and money savings provided by the solar collector to the family. (Specific heat of water at room temperature=4.18kJ/kg*C)
