Solid wood parquet on underfloor heating

Sure, but wouldn't you also say that the process is more complicated with glued-down planks? After all, the glue holds over the entire surface, meaning you either have to "scrape out" the entire plank piece by piece or at least destroy an adjacent one to get a starting point from the long side underneath the plank, and then you have to remove glue residues from the floor to get it as even as possible.
With floating floors, you simply cut the connection to the other planks and just lift them out.

With glued floors, it is actually easier in the end. The floor is firmly glued down. Sure, you have to scrape a bit. But you don't have to replace the entire plank, just what is damaged.
Floating floors are always a pain when you have to replace a floating plank. And gluing it to the subfloor is the same as with the glued variant—with the downside that in the long run it looks worse because everything moves around the glued plank if need be. Additionally, you probably won't get the correct height—the floating installation still has the impact sound insulation underneath.

P.S. In the last 25 years of working with parquet, I've never had to replace anything. Despite a big dog, three children, and parquet in the kitchen. So it's more of a theoretical topic anyway.

Ok, I hadn’t thought of just replacing a small piece yet. And I probably underestimated the "adhesive strength" of parquet glue. I only know from reports that it’s a real hassle. By gluing in, I didn’t mean fully covering the surface, but as described in my previous post.

For what reasons? I don't understand. I only see the floor layer saying "I don't feel like doing it."

Quite possible, but for the bedrooms I have decided on floating installation anyway. We might renovate one of the rooms in a few years. Besides, then we won't have any fumes from the adhesive there. That's certainly the weakest argument, but it suits us that way. For the living room, however, I have decided on the glued version if possible based on the subfloor. Only if that's not possible, then floating there too. At least now he knows my customer's wish.

In the meantime, the floor has been completely laid and in hindsight, I am also glad that I had it glued down at least on the ground floor. On the upper floor, we had it laid floating. The springy and somewhat spongy feeling when walking over it takes some getting used to. I also have the feeling that in some areas of the rooms it varies slightly in firmness. But now it is as it is. It is to be expected that the planks give a bit when walking on them. I don't know if the floor underneath is completely level, but it was additionally leveled. Hopefully, this does not harm the parquet. The parquet is relatively dry. But I think that is due to the natural oil. According to the description, it is supposed to preserve the natural character of the wood. The floor was treated with parquet soap, but unfortunately, in some places you can see the round streaks from the floor cleaning machine when looking against the light. However, I think these can be removed again. I am supposed to always use the parquet soap when mopping the floor damp. What do you actually think of spray mop vacuum cleaners? In your opinion, can they be used on parquet?

What do you actually think about wet vacuum cleaners? In your opinion, can they be used on parquet?

Normally, vacuuming is enough for parquet. Wiping over it with a damp cloth once a quarter (unless you make a mess) is sufficient.

that's practical, ... in a few years you can give competent advice here on the differences ;)

I don't find treating parquet difficult (because in my experience you rarely have to do anything), but I haven't found a really good solution yet.
My wife uses a "care product" that goes into the water while mopping and is supposed to clean and finish at the same time.
I suspect that it is a version of soft soap, which, I believe, has been used for hundreds of years. Soft soap contains fats in addition to soap, which "oil" the wood surface.

What I find lacking in this method is the removal of dirt. When mopping, it is practically just spread around again. ... for a while that may be okay, but for hundreds of years? :rolleyes:
