markharro Posted January 13 Share Posted January 13 I read about this issue on a passive house blog. We will have our system put in in a few months and the flow and return pipes will go through a ground floor bedroom ceiling. Will there be any noise issues? If so how to mitigate? I think you can get special pipe fittings with rubber gaskets? Would those be worthwhile? thanks Link to comment Share on other sites More sharing options...
Conor Posted January 13 Share Posted January 13 Use plastic pipes and lag. Don't fix to the ceiling joists and have a layer of mineral wool insulation under. Won't hear anything Link to comment Share on other sites More sharing options...
JohnMo Posted January 13 Share Posted January 13 Unless you have super small piping or a huge ASHP there is no noise from piping, from what I have experienced. Link to comment Share on other sites More sharing options...
Kelvin Posted January 13 Share Posted January 13 (edited) There’s a very slight hum at the manifold with ours. The pumps are near silent. I’m very pleased with how quiet it is as the plant room backs onto the study. The ASHP is louder than I was expecting but it is running in floor drying mode currently.

ReedRichards Posted January 13 Share Posted January 13 When my flow and return pipes were first installed above the kitchen they were quite noisy, almost a resonance. But after they were insulated that noise ceased. Link to comment Share on other sites More sharing options...
