Good morning everyone,
I would like to introduce myself briefly. We are 33 and 34 years old and have a 2-month-old son.
We built our house with Heinz von Heiden in 2016 in the Rems-Murr district, Baden-Württemberg, and moved in August 2016. Everything went well during the construction phase, but since yesterday we have a major problem with the heating system. Of course, the builder and the heating installer have already been informed. The latter is supposed to contact me tonight.
Installed is a Wolf CSZ-2-14/300 gas heating system. The heating system was commissioned on 15.04.2016. I must admit, to my shame, that I have not had any maintenance done so far. Only the chimney sweep visited twice and said everything was fine.
For the past 2 days, we have had an extremely sharp smell in the utility room (not a basement). My gas detector has not gone off, but the smell bothered us so much last night that we called the gas emergency service of the supplier. They came immediately and could not detect any gas leak at the gas system, which was a great relief.
Next, they noticed the heating circuit distributor of the underfloor heating (ground floor), which is also in the same room, and found CO (carbon monoxide) (20 ppm) coming from the lower right corner. However, they could not tell me where it was coming from. The amount is low but enough to make the whole room smell strongly. Now comes the main question: where is this coming from? I turned the heating on via the thermostats. All actuators opened, and after I turned them off again via the thermostats, they closed properly. The smell is still there. The heating system itself shows no faults. I have considered turning it off to see if the smell improves or disappears completely.
The friendly emergency service technician also noticed that the traps (3 pieces in the utility room) were all nearly empty. He explained this as follows: Since it rained heavily for the past 3 days and the sewer system created negative pressure, the traps were practically emptied. This probably caused some of the smell but is not the source. We refilled the traps, and it seems somewhat better. If the utility room door and window are closed, you start getting headaches after about 15 minutes.
Because I fear a health hazard and we have a baby in the house, I have now called all Wolf-specialized heating installers in the area, but none have the time or willingness to take a look. Do you have any advice on what I can do?
Best regards

chand198618 Jul 2019 22:23Based on the type of smell, I would guess the same as Joedreck. It smells like decomposing animals. If it’s not in the pipe, are there any shafts nearby for windows, inspection hatches, or any “rubbish” lying around that hasn’t been checked yet? A dead mouse could cause a strong odor.
There is nothing stored in the utility room. However, we do have a cat. There is no basement, and the area around the utility room is only paved. There is no clutter lying around. But thank you for your suggestions. The landscaping contractor is scheduled to arrive at 2:00 PM, then the inspection chamber will be opened and cleaned with a drain cleaner. If that doesn't help, I will call a professional drain cleaning company on Monday that has the capability to inspect the pipes using a camera.
