Hello Sebastian,
Just because you seem to like installing them doesn't mean you have to get offended right away.
There are days when I can read your posts and click on to the next thread; then there are days when I just can't manage it. Today is one of those; especially since you are playing into a cliché.
Just for the record – we install both split units and systems that are completely installed indoors. However, I don’t like it when nonsense is written about one system or another; all split units are subject to regulations regarding noise emissions... even supposedly cheap ones.
Even if you don’t want to believe it, acoustic air pollution is increasing more and more, and those units are also among the causes.
Then may I assume that, for example, you completely give up your own car? You gladly forbid moped riders from practicing their hobby, ban skateboarding altogether, and simply forgo every barbecue in your future garden? Let’s keep things in perspective!
I’ve already heard devices from, for example, Waterkotte, which were hardly audible... so better to read with a clear mind and not look for the hair in the soup.
You can also install an Ochsner instead; then you’ll just have the "noise" inside, instead of outside ;)
My mind is working perfectly today; thanks ;)
