Definitions

  • the invention relates to a heating system with a heat generator, the one Heat exchanger supplied with heat, the heat exchanger on the output side a heating circuit with radiators and a domestic hot water charging circuit for one Domestic hot water tank feeds with hot water, whereby in the lower area of the Domestic water storage cold water taken out, via a domestic water charge pump and the heat exchanger in the upper area of the domestic hot water tank warmed up and fed back to the domestic hot water tank Cold water can be supplied in a process water circuit in the lower area and hot service water in the upper area via connected taps is removable.
  • the hot water outlet the hot water circuit in front of the tap via a circulation line and a backflow preventer with the inlet of the domestic water charge pump is connected between the cold water outlet of the domestic hot water tank for the domestic water charging circuit and the heat exchanger is looped in and that between the cold water outlet of the domestic hot water tank for the domestic water charging circuit and the domestic water charging pump a loading water flow limiter is looped in, which can be specified on a Charge water volume is set.
  • the process water charging pump becomes the process water charging circuit also as a circulation pump for circulating the domestic water used and thus avoided a separate circulation pump without to have to do without the function of circulating the domestic water.
  • the amount of charging water required for stratified charging can be independent set by the circulation circuit if it is provided that in the process water charging circuit between the process water charge pump and the A water flow limiter is looped in on a heat exchanger Total amount of water is adjustable by the sum of the amount of charge water and circulation water amount is set.
  • the heat exchanger is designed as a two-circuit heat exchanger, the one heat exchanger assigned to the heating circuit and the other heat exchanger to the process water charging circuit then there may be a circulating water volume when the domestic hot water charging pump is operating regardless of the amount of water loaded and fed back to the process water charge pump via the circulation line become.
  • An embodiment is advantageous which is characterized in that the Heat generator is designed as a gas heating system, because then the heat distribution in the heat exchanger optimally to the requirements of the heating circuit and the Custom water charging circuit can be adjusted.
  • the water quantity limiters are as Fixed chokes and adjustable in the amount of water.
  • the invention is based on a hydraulic circuit diagram according to the Invention designed heating system explained in more detail.
  • a heat generator not shown, e.g. a gas heater supplies you Heat exchanger 3 on the input side with heat. Is this heat exchanger 3 as Dual circuit heat exchanger is formed, then the one heat exchanger the heating water flowing through for the heating circuit HK is heated up while the second heat exchanger supplies the domestic hot water charging circuit SK with heat.
  • the hot water tank 10 is heated via the hot water charging circuit SK.
  • Cold water is fed through the cold water outlet wa in the lower one Removed the area of the domestic hot water tank 10 and a charging water volume limiter 6 limited to a predeterminable charging water pump.
  • a process water charge pump 1 the loading water quantity via a further water quantity limiter 2 and Heat exchanger 3 via the hot water inlet ww of the domestic hot water charging circuit SK warmed, again the upper area of the hot water tank 10 feeds.
  • the actual process water circuit BW is separate from it.
  • the cold water KW is the cold water input wa of the hot water tank 10 in the lower area fed.
  • the hot hot water is turned on Dispensing points 5 supplied.
  • a circulation line 7 branches off via a Backflow preventer 4 leads to the input of the domestic water charge pump 1.
  • the backflow preventer 4 decouples the circulation circuit ZK from the process water charging circuit SK.
  • the process water charging pump 1 promotes the charging and Circulation water quantity via the water quantity limiter 2 to the heat exchanger 3, based on a maximum flow rate as the sum of the two Amount of water is fixed.
  • the hot water charge pump 1 is corresponding designed. In this way, the DHW charging circuit SK and the circulation circuit ZK coupled so that the domestic water charge pump 1 also as a circulation pump serves for the circulation circuit ZK.
