  • the inventive leads Construction of the heating device also to ensure that when the burner was not in use, it warmed up relatively quickly Domestic water can be tapped, with the Hot water storage can be dispensed with.
  • a heating device 1 comprises according to the invention a burner 2, which corresponds to a Arrow 3 with fuel, e.g. Natural gas or heating oil becomes.
  • the burner 3 heats one during operation
  • Primary heat exchanger 4, which is in a heating circuit 5 is involved, i.e. the primary heat exchanger 4 is from a heating fluid, in particular water, of the heating circuit 5 flow through.
  • the upstream of the Primary heat exchanger 4 is arranged in the heating circuit 5.
  • the Preheater 7 is designed so that it over the Heating circuit 5 can absorb and store heat. Heat stored in the preheater 7 can be used if necessary again delivered via the heating circuit 5 and according to the invention be transferred to the primary heat exchanger 4.
  • the heating device 1 also has a control unit 8 on that via control and / or signal lines 9 with the Pump 6, with a first temperature sensor 10, the Temperature in the preheater 7 measures, and with a second Temperature sensor 11 is connected, the temperature in Heating circuit 5 downstream of the primary heat exchanger 4 measures.
  • the heating circuit 5 has one Main branch 12 and a secondary branch 13.
  • the main branch 12 contains at least one, not shown here Main heat consumers.
  • the main branch 12 leads over a lead 14 to the at least one Main heat consumers.
  • a return 15 of the main branch 12 returns the heating fluid.
  • the at least one Main heat consumers of the main branch 12 can, for example a heated pool, especially a swimming pool, his.
  • This main heat consumer can also be a Form heating line system of a building central heating that one or more radiators, in particular also Underfloor heating circuits.
  • the secondary branch 13 connects the flow 14 with the return 15, with 13 at the junction between secondary branch and return 15, a switching valve 16 is arranged, the by means of an actuator 17 via a corresponding control and / or Switching line 9 can be actuated by control unit 8.
  • the switch valve 16 Depending on the switching position of the switching valve 16, the promotes Pump 6 the heating fluid completely or partially through the Main branch 12 or in whole or in part by the Secondary branch 13.
  • a secondary heat consumer 18 be arranged.
  • this is Secondary heat consumer 18 around a secondary heat exchanger 19, the one with a hot water circuit 20 by the way not building water heating system shown is coupled to transfer heat.
  • leading away from the secondary heat exchanger 19 Management of the hot water circuit 20 can be a third Temperature sensor 21 may be arranged via a corresponding signal and / or control line 9 also with the control unit 8 is connected.
  • the heating circuit 5 can be connected to the secondary heat exchanger 19 its secondary branch 13 heating output in the hot water circuit 20 transferred if there is a corresponding need.
  • the Hot water circuit 20 can go directly to corresponding Run hot water taps.
  • the secondary branch 13 is parallel to Main branch 12 switched or with the heating fluid flow through.
  • the preheating store 7 in Heating circuit 5 or in the secondary circuit 13 downstream of the Secondary heat consumer 18, that is, the secondary heat exchanger 19 is arranged.
  • the memory 3 can be in another embodiment in the heating circuit 5 next to the preheater 7 another Memory 22 may be arranged.
  • This memory 22 can serve for example for storing hot heating water and therefore part of a central heating system form. Accordingly, the memory 22 has one Forward 23 and a return 24. Basically it is there possible that the same heating fluid flows in the heating circuit 5 as in forward 23 or in return 24. That means that the Memory 22 allows fluid exchange.
  • the heating circuit 5 from the flow 23 and be separated from the return 24 of the central building heating, so there are separate circles.
  • the memory 22 can also be used to store serve hot domestic water, in which case it is a component a building water heating system. Accordingly, the lead 23 then supplies the Hot water taps of the water heating system, while over the return 24 fresh and cold Industrial water is refilled. Likewise, a Hot water system with permanent hot water circulation be provided so that the return 24 circulates and if necessary, hot water topped up with fresh water Memory 22 returns.
  • the memory 22 accordingly forms in this embodiment a heat consumer.
  • a fourth temperature sensor 25 measures the temperature of the Storage 22 or the fluid stored therein and is with a corresponding signal and / or control line 9 the control unit 8 in connection.
  • the heating device 1 works as follows:
  • the at least one, not shown, arranged in the main branch 12 Main heat consumer no longer needs heat, switches the burner 2 off.
  • the pump 6 can be switched off.
  • the pump 6 continues for a predetermined run-on time operated.
  • the actuator 17 Switching valve 16 switched so that the secondary branch 13 and thus the preheater 7 are flowed through.
  • the cooling of the Primary heat exchanger 4 advantageous for the lifetime of Primary heat exchanger 4 off, because excessive temperatures can be avoided by the after-heating effects mentioned.
  • the Overrun mode is switched off, for example, when the predetermined follow-up time has ended.
  • Parameters for the after-run mode that in the preheater 7 achievable temperature are used. For example the pump 6 is switched off when the Follow-up operation for no further temperature increase in the Preheater 7 leads.
  • the preheater 7 is useful effectively heat insulated so that the heat stored therein decreases only relatively slowly.
  • the control unit 8 a heating power requirement burner 2 must be started again.
  • the pump 6 can now be activated to at least in the preheater 7 stored thermal energy partly via heating circuit 5 to the primary heat exchanger 4 to transfer.
  • the switching valve 16 must again are switched so that the heating fluid through the Secondary branch 13 flows.
  • this measure shortens the heating-up time of the primary heat exchanger 4, so that after a relative shortly sufficient heating fluid in the Heating circuit 5 is transported.
  • this time can be determined to which the switching valve 16 is then also switched, that now the main branch 12 for supplying the or Main heat consumer flows through with hot heating fluid becomes.
  • the burner 2 therefore only switches off when both the or the main heat consumers of main branch 12 as well the secondary heat consumer 18 has no heat requirement.
  • a heat requirement leading to switching on the burner 2 can then in this embodiment, for example are present when 20 hot water are drawn from the hot water circuit will or should be.
  • the pump 6 is then also activated here and the Switch position of the switching valve 16 selected so that the Sub-branch 13 is flowed through. This is how the warmth of the Preheater 7 back into the primary heat exchanger 4, which shortens its heating-up time. this leads to a noticeable increase in comfort for the hot water circuit 20, since the hot water desired by the invention Measure can be provided faster.
  • the Pump 6 are activated to the in the preheater 7th stored heat via the heating circuit 5 on the To transfer primary heat exchanger 4. Which is thereby shortening the heating time of the primary heat exchanger 4 leads here too, that the memory 22 faster with hot Heating fluid can be supplied.
