  • a heat recovery device is either a system that works on the principle of a heat pump or, in particular, a solar collector ⁇ to be understood as meaning possibly also several connected solar collectors.
  • the energy obtained by means of warming-up is used in part to heat living rooms and to heat service water.
  • Such heating systems are fundamentally known

  • a hot water zone is connected to a central firing zone in which at least one firing space can be heated with fuel , in which a heat transfer device for heat transfer between the heating water and a process water system is located.
  • Below the firing zone there is a preheating zone in which the heating and process water can be heated or preheated using the heat obtained from the heat recovery device.
  • These three zones not only have different functional meanings, but are also zones of different temperatures. Due to the greater density of the colder water, it will sink down in the boiler and settle in the Accumulate preheating zone This is advantageous in that heat exchange takes place between the heat recovery device and the heating water.
  • the uppermost zone of the boiler in which a higher temperature prevails than in the preheating zone, is used for heating service water.
  • the heat transfer between the heating water and a service water system is achieved in that a boiler is located on the top of the boiler or a container is let in, the walls of which are arranged inside the boiler and are permeable to heat.

It is also conceivable to enlarge the surface, for example in the form of indentations extending into the interior of the boiler.
  • An advantage of the proposed arrangement of the boiler is that it is completely can be simply manufactured and does not have to have insulated walls
  • a heat exchanger is arranged in the preheating zone, which is fluidly connected on the inlet side to a process water supply network and on the outlet side to the boiler , a municipal drinking water supply network, for example, and generally relatively cool water can therefore already be heated almost to the temperature of the heat carrier before it is fed to the boiler.
  • the cool hot water supplied results in the the heating water located in the preheating zone cools down. This cooling increases the temperature difference between the heat carrier heated by solar energy and the heating water, so that - as already explained above - the heat transfer rate is increased.
  • the heating water in the preheating zone is heated in principle by the heat carrier of the heat recovery device in that the heat carrier is brought into direct or indirect contact with the heating water.
  • a heat exchanger is arranged in the preheating zone, which on the one hand receives the heat recovery device and on the other hand the outlet of which is fluidly connected.
  • the heat exchanger circuit flow flows through the heat exchanger and is maintained by means of a suitable pump, the heat transfer taking place between the heat carrier and the heating water.

  • the recovery device does not have to be filled with a separate heat carrier when newly installed after repair or the like. Rather, the filling can be carried out together with the entire heating system with tap water.
  • the heat exchange is compared to a heat exchanger Improved, since the heat contained in the heat carrier does not have to overcome any system limits, for example the walls of a heat exchanger.
  • Such a coupling of the heat recovery device is useful not only in the case of a boiler according to the invention but also in any boiler design
  • the heat recovery device is preferably a solar collector, which is connected to the boiler via a return line.
  • the solar collector is arranged at the highest point of the heating system.
  • a compensating container is interposed in the return line.
  • the pump that maintains the heat transfer circuit is switched off, it runs, due to the standing with the atmospheric air bubble Haiter in Austiciansbe ⁇ , the solar collector empty the collector can, if required, such as frost, be emptied in a simple manner and thus o f a be Filling the solar collector system with antifreeze can be dispensed with.

  • the heat carrier In systems in which such an emptying is not possible, the heat carrier, the Usually water is used, an antifreeze is added.However, this increases the viscosity of the heat carrier, so that correspondingly larger pipe sizes and appropriately dimensioned internals are necessary to achieve the desired circulation rate: If the circulation pump comes to a standstill due to a power failure, the circulation pump runs Heat carrier also automatically out of the solar collector what particularly beneficial in the winter months when there is a risk of freezing
  • the radiators of a heating system are preferably arranged below the lowest liquid level of the surge tank.
