Carpet in the bedroom despite underfloor heating?

How was the calculation done? What about the others here who have carpet... what are your experiences like?

u-wert.net calculates that.

I can't quite follow your calculation so spontaneously, but that doesn't have to mean anything. Also, I think it's not very helpful at first to throw a lot of numbers with many decimal places into the room. :P

For the questioner, maybe the following helps. To have a warm room, heat must enter the room, which happens via the underfloor heating. The following relationship applies:
Heat (in watts) = heat transfer area (in m²) * heat transfer coefficient (in W/m²/K) * temperature difference (in K).

The heat transfer coefficient is called the U-value. The area for underfloor heating is practically the living area of the room. The temperature difference is the difference between the room temperature and the underfloor heating flow temperature.

For floor coverings, transmission resistances are now given. This is nothing other than the reciprocal of the U-value, hence the unit K m²/W. The greater the transmission resistance, the worse.

Why is it worse? To introduce the required heat output (watts), practically only the temperature difference can be varied. The area is fixed. A low heat transfer coefficient (high resistance) must be compensated by a higher temperature difference. This necessitates a higher flow temperature, which in turn reduces the efficiency of a modern heating system (heat pump).

How many euros per month this will be afterwards is for others to calculate. I would be relaxed about it.

Where is the carpet supposed to be laid?

In the bedroom, in my opinion, that wouldn’t be so dramatic. The carpet feels warm but doesn’t necessarily make the bedroom warm. That’s exactly what you want in the bedroom, isn’t it?

My parents have full underfloor heating in the house and only tiles in the kitchen/entrance area, the rest is also carpet (Vorwerk). The house is warm, it is very comfortable for the feet and even after many years it still looks great.

Therefore, we will also lay carpet in the bedroom/dressing room and guest room.

As for the dust issue: the amount is not dependent on the flooring. With carpet, it is just in the fibers, with smooth surfaces it flies around. Regular proper cleaning is necessary in all cases.

Hello,

should be used for the bedroom, dressing room and other rooms. Thanks for the Erfahrungsberichte. We are taking the risk now
