I’d stump up the extra for Rehau in slab piping.
The Europeans are the experts at it. For 25sqm, the price difference between Rehau and generic Pex isn’t going to be much.
From speaking to my installer, he advised if the pipes are too close to the top of the slab, it won’t heat up properly.
So make sure the pipes is ~50mm below the top of the slab.
There’s no better heating IMO but it does cost more to run than hydronic panels.
