Floor tiles for energy-efficient living


At 51.5 percent, heating is the largest consumer of energy in the household; followed by the car with 31.4 percent.

The remaining consumption is divided as follows:

  • 1.04% lighting
  • 8,1% cooking
  • 8.0% hot water

Although every measure that reduces energy consumption is important, the topic of energy efficiency in heating is particularly appropriate. In addition to modern heating systems, floor and wall coverings make an important contribution. The combination of underfloor heating with ceramic floor tiles has the highest energy efficiency and achieves savings of up to 30 percent. This savings potential also applies to the installation of a wall surface heating with a tile wall cladding.

No invention of the modern age

The numerous advantages of ceramic tiles were already exploited by the Romans. The old Romans heated their bathhouses via underfloor and wall heaters, which produced a healthy and pleasant radiant heat. The same basic principle was used as it is today in modern underfloor heating systems. The energy used for the central kiln was wood, which produced about 250° C hot air during combustion. This warm air rose above the clay pipes laid throughout the building and heated the rooms lined with ceramic tiles.

Thermal resistance of floor tiles highest

An important point in choosing flooring in combination with underfloor heating is the thermal resistance, which is calculated from the thermal conductivity and the thickness of the material. The lower this value, the more the flooring increases the efficiency of the heating. To calculate the thermal resistance (R), the thickness of the floor covering (d) is divided by its thermal conductivity (?).

Tiles have the lowest heat transfer coefficient (m² K / W) of all materials and are therefore best suited as flooring.

  • Ceramic tiles - 0.012 m² K / W
  • Marble - 0.014 m² K / W
  • Laminate 9 mm - 0.044 m² K / W
  • Parquet - 0.10 - 0.15 m² K / W
  • Carpets 4.5 mm - 0.12 m² K / W
  • Cork floor - 0.13 m² K / W

If the underfloor heating additionally serves as passive room cooling during the hot months, floor tiles also show the best results here.

The advantages of tiles for wall and floor

Floor tiles are attractive and wonderful design elements, as the exciting range of tile-kemmler.de proves. But these are just two of the many arguments in favor of ceramic tiles:

  • Durable and robust
  • Hygienic
  • Save the sun's heat in winter
  • Cooling effect in summer
  • Easy care
  • High energy efficiency

Therefore, it makes sense to learn early about the many possibilities of saving energy by laying ceramic floor and wall tiles.
