This means that theoretically you should insulate pipes to a depth of 1.5 m, but in practice I think that is enough to isolate less, likely to 1m depth max. Of course, all parts of the pipes that come from the soil should be well insulated, and separated each one of other.
For this purpose, Styrofoam or similar can be used ...

I agree that the pipes should be as deep as is reasonably possible. And I also agree that they should be below the frost line.
Where I live, the frost line used to be 18 inches (about 0.5 meter), but now it has been re-defined as 9 inches (about 0.25 meter). So, compared to some other parts of the world, it doesen't' get very cold here.
You didn't mention where you live in your post Nikolai, but a frost line of 1.5 meters means that you must live pretty far North or South, or at a very high altitude.
Where do you live?
There is another reason why running pipes deep would be a good idea, and that is that they draw in heat in a circular pattern. So if they were deeper, there would be more area in the circular pattern to draw from.
