ᐅ Installing Underfloor Heating in Wood Flooring?

Like many others, we are switching our heating system from an oil burner to a heat pump.
In the newly renovated upper floor, we have underfloor heating, which we find very comfortable.
However, in the main living floor, there are still traditional radiators (installed only 4 to 5 years ago).

The living room has solid oak parquet flooring, 20 millimeters thick (about 0.8 inches), also nearly new.

For an energy-efficient conversion to underfloor heating, I’m considering how to do this smartly.
To save space, there is the complex method of milling channels into the floor for the pipes.
Now I’m wondering if this “milling method” could perhaps be done even more easily in wood.

I assume this is nonsense because wood is a good insulator and the pipes should naturally transfer heat sideways.
Normally, the pipes are embedded in a cement screed, but I’m not sure if grooves milled into wood would work for underfloor heating, since the pipes would presumably need to be embedded there as well.
Above that would be oak parquet again, but obviously much thinner (there are versions at 8 millimeters thickness (about 0.3 inches), like the ones we have under the roof).
I guess it would be too much wood with too little mineral material—a combination of two materials that don’t really go well together anyway.

But I haven’t fully worked this out yet and would appreciate any ideas on this.

Yep. It is. For so many reasons that it would take a whole book to list them all. Even if the hardwood floor is that nice, I would start by running the heat pump with radiators. That works well and you only need to adjust the radiators.
