Forgot drainage connection chimney

Find a solution for what? As you have learned from the posts, no one has drainage.

I think you are currently setting up the wood stove? Then you will operate it as well. This should solve the problem by itself, even if you don't use it for 3-4 months in the summer.

Chimneys usually have a condensate drain that should be connected to the sewage system.

Is there the possibility to place a collecting container in the mantle stone?

No matter what kind of moisture comes in, it must also go out again.

Both my architect planned it, and independently, my stove builder mentioned it.

There must be something behind it.

Our simple chimney for the wood-burning fireplace also has a condensate drain. However, since not much condensate accumulates, the pipe is simply led outside and that's that.

Hello,

our chimney also has a condensate drain, which was integrated directly into the floor slab under the basement.

However, it was necessary to inquire with the city drainage whether a direct connection of the chimney to the sewer system is permitted.
