Definitions

  • the present invention relates to a heating system with a condensation boiler and the features listed in the preamble of claim 1.
  • Such heating systems with a condensation boiler have a circulation pump in a flow line, which supplies the flow water to consumers via thermostatic valves.
  • the flow water is cooled by releasing the heat to the rooms to be heated and returned to the condensation boiler through a return line.
  • An overflow valve parallel to the thermostatic valves and the consumers allows the flow water to flow directly into the return line when the thermostatic valves are closed.
  • the present invention has for its object to eliminate this disadvantage and to provide a heating system in which, in addition, the amount of water in the consumer circuit can be made variable and the residence time of the water in the heating circuit when the thermostatic valves are closed can be increased.
  • the increase in the spreading time means that the return water is always at the lowest possible temperature, making maximum condensation possible.
  • a heating system has a condensation boiler 1 which, with the aid of a circulation pump 3 located in its feed line 2, supplies hot water via thermostatic valves 4 to consumers 5, which are connected to the condensation boiler 1 via a return line 6.
  • An overflow valve 7 is connected hydraulically between the suction side and the pressure side of the circulation pump 3 in such a way that its direction of passage is opposite to the flow direction of the circulation pump 7, that is to say the overflow valve 7 is hydraulically antiparallel to the circulation pump 3.
  • overflow valve 7 ensures that the amount of water in the consumer circuit is variable and thus the dwell time when the thermostatic valves 4 are closed becomes longer. Since no feed water gets directly into the return line 6, there is always the lowest possible return temperature of the water in the return line 6, which results in the greatest possible condensation desired for economical operation of the condensation boiler 1.
  • the present solution uses a circulation pump 3 and an overflow valve 7 of a conventional design.
  • the circulation pump 3 and the overflow valve 7 are also conceivable to design the circulation pump 3 and the overflow valve 7 as a structural unit, which makes their installation in the heating system even easier.
  • a circulation pump and an overflow valve which are to be provided in known heating systems anyway, do not incur any additional costs for the arrangement described in comparison with known solutions.
  • the measures described enable a particularly effective operation of the condensation boiler and thus bring significant savings in heating costs.
