Definitions
- the pump is outside the boiler is arranged.
- the pump is accessible from the outside, so that the maintenance of the pump and thus the circulation device is simplified as a whole.
- this may also be provided with a unitberichtdämmein, which reduces the heat transfer to the insulating fluid in the innermost heat exchange member to the outside atmosphere.
- the thermal insulation unit is designed for example as a thermal barrier coating and envelops the innermost heat exchange member partially or fully.
- the pump inlet opens in an upper region of the boiler in its interior. According to this further development of the invention, the pump sucks during cold start buildss insulating fluid in the circulation, as the heated insulating fluid due to its lower compared with cold ren insulating fluid density in the upper region of the Kels sels accumulates. This accelerates the cold start even further.
- FIG 4 shows another embodiment of the inventions to the invention transformer 5, which corresponds to the embodiment shown in Figure 3 as far as possible.
- the pump 15 is disposed outside of the boiler 6, wherein the pump inlet 16 and the pump outlet 17 each extend through the wall of the boiler 6 into the interior of the boiler 6 inside.
- Figuress not shown sealing means ensure that the insulating fluid 7 can not escape from the boiler 6.
- the mouth or Publ tion of the pump inlet 16 in the region of the mouth of the Radia gate drain 4 is located.
- the mouth of the Radiatorab run 4 can also be more generally referred to as the output of a connecting pipe 4 between the boiler and radiator 1. The same applies to the inlet of the inlet 2.
- the load control at cold start in the invention may be arbitrary. Notwithstanding the above reactions of the cold start, the electrical device according to the invention can also be started under full load ge.
