ᐅ Is it possible to hear a floor heating system?

Yesterday, the walls and roof were filled with insulation (something like Isofloc). Our underfloor heating system is installed in the floor and has been running for a few days now, warming the screed.
(Just to give you an idea of how new everything is.)
This morning, there is a soft but distinct rushing sound coming from there.

Could that be water flowing in the pipes? ... I hope not 😱

Were the circuits properly vented? A slight flow noise very close by can be normal, but you need to have your ear near the manifold for that.
If you hear something while just standing in the room, it’s too loud.
Possibly, the circulation pump is running at full capacity.
I would rather suspect insufficient venting.

Hello,
underfloor heating should operate silently, unless you listen directly at the radiator/manifold valves. Could the circulation pump be running at the highest setting?

Best regards,

Andreas

Yes, I have tried to find the source of the noise. So far, without success.
It is possible that there is still air in the pipes... (the initial runs are still ongoing)

My main question is:
Are there underfloor heating systems that make noise inside the pipes? (I assume not, but I am not certain)

Where exactly is “there”?

As mentioned here before, if anything, the noise is a slight rushing sound from the HVAC system.

So, ours is absolutely silent. I mean the pipes in the floor.
The only audible sounds are the thermostats occasionally making a "click" noise.
