ᐅ Carpet over underfloor heating?

We are currently considering installing carpet instead of hardwood flooring on the upper floor of our planned house. However, there are warnings about using carpet together with underfloor heating due to carpet’s poor thermal conductivity. Does anyone have experience with this and can offer advice?

Regards.

By *whom* are you being warned?

Good morning,

I thought so.

When purchasing carpet, you need to make sure it is suitable for underfloor heating; there is nothing else to consider.

If necessary, you should also inform your planner about this – roughly, carpet has a similar thermal resistance coefficient to hardwood flooring:

Carpets: 0.07 – 0.17 m²K/W (0.4 – 1.0 ft²·°F·hr/BTU)
Needlefelt: 0.12 m²K/W (0.7 ft²·°F·hr/BTU)

Engineered wood flooring: 0.03 – 0.15 m²K/W (0.17 – 0.86 ft²·°F·hr/BTU)
Strip parquet (oak): 0.08 m²K/W (0.46 ft²·°F·hr/BTU)

If you hadn’t planned very thin hardwood flooring before and are now using the 2 kg/m² (4.1 lbs/ft²) rubberized stick-on carpet, it probably won’t make much difference after all.

Thanks for the answers. It seems I was probably stressing over nothing. However, I will bring it up with the architect again.

Best regards.
