Hansebeton or Schiedel?

Hello, I was at a building materials dealer yesterday regarding our new building. I wanted to have a 150 pipe installed for the supply air for our wood stove in the living room. Because the LAS CHIMNEY was too expensive for me. They offered me a Hansebeton for a price I would accept. Does anyone know these chimneys, can I use them without any problems? Thanks Regards

That is a fairly large precast concrete manufacturer, garages, paving slabs, retaining walls and more from Lauenburg near Hamburg. No nonsense. Their garages, for example, are practically the standard model in the North.
