本发明涉及的加热系统与吸收式热泵，推进器通过用超化学Luftvormischung气体燃烧器，其完全和部分负荷效率都同样大，并且废气具有非常低的NOx含量工作加热。 燃料气体燃烧空气混合物流出至少一个混合管（2）进入混合室（3）和烧伤，其中被布置在小于50毫米到推进器（17）的距离的冷却通过富溶液燃烧器板（4）。 对于垂直压榨，燃烧器，优选使用，所述燃烧器板同心地围绕压榨在距Austreiberboden这样的高度，只有中间Austreiberbereich被直接加热。 在排气通路优选使用废热，包括冷凝的热量的两个热交换被布置一个推进器的后面。 由于在第一热交换器（9），以代替燃烧器的排出器加热的下降到低于下限温度时被投入运行之前一个第二燃烧器（19）的本发明的装置，该加热系统能够满足热需求，即使在低的外部温度。

The invention relates to a heating system with an absorption heat pump, the expeller is heated by a working with superstoichiometric Luftvormischung gas burner whose full- and part-load efficiency are equally very large and the exhaust gas has a very low NO _x -contents. The fuel gas-combustion air mixture flowing from at least one mixing tube (2) into a mixing chamber (3) and burns in a cooled by-rich solution burner plate (4) which is arranged at a distance of less than 50 mm to the expeller (17). For perpendicular expeller a burner is preferably used, the burner plate concentrically surrounds the expeller at such a height from Austreiberboden that only the middle Austreiberbereich is directly heated. In exhaust path preferably two heat exchangers for utilization of waste heat, including the heat of condensation are arranged one behind the expeller. The inventive arrangement of a second burner (19) before the first heat exchanger (9), which is taken when falling below a lower limit temperature in place of the burner for expeller-heating in operation, this heating system can cover the heat demand, even at low outside temperatures.
