I am currently building an apartment in a multifamily building. This apartment will have a fireplace. The fireplace (Hark 350k) has already been purchased. Now I still need the right chimney. Since I don’t have much knowledge about this, I am reaching out to you. The fireplace should be connected to the chimney through the exterior wall.
Here are the questions I have:
What exactly do I need? I have already seen chimney systems online, but I’m not sure if they include everything I need. I know that I will need a chimney about 4–4.5 meters long, 200 mm (8 inches) in diameter. Double-walled with insulation between the walls (how thick should this insulation be?). Do chimney systems also include the wall penetrations, or do I have to get these separately? Are all chimney systems designed for external air supply (room air independent), or do I need to pay attention to that as well? What else should I consider?
What is an appropriate price for a chimney system? And what does the whole installation typically cost if done by a professional?
Thank you in advance for your help.
Best regards
Lukas

Hello,
The chimney must be sized according to the requirements of EN 13384 and constructed following DIN 18160 Part 1.
By the way, the final decision lies with the local chimney sweep, so it is advisable to consult them in advance!
Unplanned self-construction often ends up as a money pit.
Best regards

Hello Lukas,
I agree with Euro on this. I met with my local chimney inspector on site beforehand, gave him the data sheet for the wood stove, and discussed the required clearances with him. He can also tell you directly which regulations you need to comply with (such as how high the chimney must extend above the roof, whether the wood stove needs to be room-sealed, if you need a fire protection wall penetration, etc.).

Thank you very much for your responses.
Yes, 9 kW is definitely powerful.
The fireplace is located in the living room (about 45 m² (484 ft²) with an average ceiling height of 3 m (10 ft)).
I must admit that I have already spoken with the chimney sweep, and we even met on the construction site. At that time, the discussion was mainly about the interior—such as the required clearances to combustible materials, and so on. I don’t recall us talking about the chimney itself, except that the flue goes outside and that the fireplace should be operated with room air independence.
I will probably call the chimney sweep again tomorrow to ask how tall the chimney needs to be. One more question: What is a fire protection wall penetration?
Thanks again for the help and tips.
Best regards,
