ᐅ Installation of Heat Pump/Heating System – Before or After the Screed?

Hello everyone,

my heating engineer can’t really decide on a preferred option. That’s why I’m asking you about your experiences:
When was/is the heat pump/heating system installed at your place? Before or after the screed? What are the advantages and disadvantages of each option?

Thank you all 🙂

Since the screed needs to dry shortly after it has been installed: before the screed.

With us, it was also installed before the screed. But on a special "pedestal" to presumably prevent any sound or vibration transmission.
When the screed is poured, the heating has to start immediately to aid drying.

Yes, there is basically only one answer: The floor screed must be heated beforehand to dry faster, and it does not become cheaper if you have to acquire other equipment for this.

So, you place the heat pump directly on the bare concrete floor and then pour the screed around it?

You can also install the heat pump shortly after the screed is laid, but before the drying process begins. Usually, there is some time before the drying starts.

That’s exactly how it is done in our case as well.
