Wood-look tiles - What do you think of these tiles?

In our well-insulated semi-detached house from 2013 (approx. 1,000m³ gas per year), the underfloor heating is already warm.

But I don't understand the whining about cold floors - please put on slippers again!
Then the socks will last longer too.

Who do you mean by whining? For my part, I am not whining.
For example, I don’t understand how you can have a "nicely warm underfloor heating" in a well-insulated new building.
At what flow temperatures is the water pumped into the heating circuits?
Your gas consumption corresponds to about 7,600 kWh – not much for the cold region. How large is your semi-detached house/final energy demand?

I agree with Cascada. In our home, the areas with tiles are noticeably cooler than the areas where we have vinyl. The tiles have not really become warm in the 1.5 years we have lived in the house. But the coldest day so far has only been -6°C. They are not unpleasantly cold, but also far from cozy warm.

Who do you mean by whining? As for me, I don’t whine. For example, I don’t understand how you can have a "nice warm underfloor heating" in a well-insulated new building. At what supply temperatures is the water pumped into the heating circuits? Your gas consumption corresponds to about 7600 kWh - not much for the cold region.

The "whining" should be seen with a Because you often read that people complain about cold tiles - I personally can’t understand that because I always wear Birkenstocks. My wife, however, is different again.

“My” semi-detached house (is rented) and built in 2013, 150m² living space + basement and ground floor/upper floor/attic. In Nuremberg we have so-called "H-Gas" with a higher calorific value. The consumption therefore corresponds more to 10-11,000 kWh, I don’t have the exact number in mind. Furthermore, there are only 2 of us and we have a solar system for domestic hot water. The underfloor heating is definitely mixed down and not operated with the supply temperature of the radiators, but how high it is now... no idea. I estimate 40-45 degrees. Not comparable to a heat pump with a supply of 30 degrees, of course.

Our tiles with underfloor heating in the new building basically do not get warm (so they feel cool, however, I walk around without slippers and it is not uncomfortable for me. My little daughter even prefers to walk barefoot. But you notice a big difference when you enter the stairs with the same tiles, but without underfloor heating: those are then clearly much colder.

@ SirSydom: not only your wife is different - all women But with gas and the associated higher flow temperatures that can be the case. But it's bad for the veins and varicose veins But then theoretically a larger installation spacing must be present. With 10cm installation spacing and 45 degrees flow temperature, otherwise you have a few 30 degrees in the room in the new building...
