1. Method for improving the efficiency of a district heating system running on hot water produced by a heating power station, in which the heat storage capacity of the district heating system is used for supplying heat to the hot water storage unit (12) of a consumer's station, whereat the heat-supply per time-unit depends on the hour of the day, and the heat is accumulated throughout the whole day and corresponds with the daily heat demand, being predicted by the outdoor temperature while the highest possible heating efficiency during the peak generating of electrical energy is exploited in the evening, characterized in that the hot water storage unit (12) is heated up to the highest possible temperature during the peak generating, and that at night when the heat demand is low, especially from 23.00 to 5.00, the heat supply in the district heating system is suspended by switching off the main pump (5) of the power plant, and, at the same time, the amount of heat necessary for the supply of hot water and/or the amount of heat radiated by the radiameters in the heating circuit is taken from the pre-heated hot water storage unit (12).
