Installing underfloor heating by milling

Hello everyone,
we want to install underfloor heating afterward in a basement room of our house. The entire basement is insulated in terms of both walls and floor.
I came across the possibility on the internet to install a water-based underfloor heating system afterward by milling the screed.

I have now inquired with several heating engineers in my area, and not a single one offers the system with screed milling.
The common opinion was always that it is better to install a wall or ceiling heating. But since children play on the floor, underfloor heating would actually make more sense.

So the question is whether anyone in this forum has already gained experience with the subsequent milling of the screed and the installation of underfloor heating?

If you invest two or three hours and take a big sledgehammer in your hand, you can quickly dispose of the screed and install a proper underfloor heating system. Then the question of how milling works doesn't even arise. Even though I've only read good things about it online, I currently prefer to remove the screed and install a conventional underfloor heating system.

I had it done, the milling. I bought a mid-terrace house from a developer who, for various reasons, refused to install underfloor heating in the screed on the upper floor. So I had no choice but to have it done afterward. It cost 3000 euros for about 60 sqm. It makes a lot of noise but thanks to good extraction, there's little dust. It's done quickly, took half a day.

Works great. I'm glad about it? In the Netherlands, this is done frequently. If you live somewhat close to the border, have a look under "infrezen vloerverwarming" or "inslijpen vloerverwarming."

If you find a company (wherever), make sure that the disposal of the milled material is discussed. A lot is really cut out there. And disposal is expensive because it's construction debris and not household waste.

I don't think the idea with the blanket is so wrong, as long as the floor is insulated. Then the temperature evens out for the most part anyway. Playing children prefer carpet over tiles under their bottoms anyway. Just lay out a play rug and heat from above.
