You are right about that being enough of that discussion.

Our heating boiler just broke during a very cold week and we had to replace it in a hurry. The plumbing company we called (M Stahl) recommended Weil-McLain CGi high efficiency direct vent through the wall boiler, which we bought. I want to mention that we do have a chimney.

Now I am extremely frustrated because it makes unbearable, terrible NOISE. It keeps us awake at night. It sounds like a powerfull vacuum cleaner. Nobody warned us about the NOISE. We called the company M Stahl that recommended and istalled the boiler. They told us that this is a normal operating noise and that I am exaggerating. Now we are also getting complains from our next door neighbors and they want to call KDKA about the noise. They cannot sleep because of it either.

I whish I was warned about the noise before making an important decision and a very expensive purchase. I hope my post will help other people buying a boiler.
