Underfloor heating

Our planks are very well suited for underfloor heating and we recommend installing it as a comfortable and durable solution. 


About 80% of our projects are established with underfloor heating and we have years of experience with underfloor heating under solid floors. It is an unproblematic solution, provided you adhere to the conditions described below. 

If you need any additional advice about Dinesen floors, you are very welcome to contact us. To order and purchase products in the maintenance series, please go to our webshop.


  • Will underfloor heating result in more cracks and similar damages?

    If the air humidity is kept between 30 and 60% RH, underfloor heating will not result in cracks etc. If the surface temperature of the floor exceeds 27 °C, it will bring the air humidity under 30%, which may deplete the wood and cause cracks. Low air humidity and inadequate care and maintenance can cause minor cracks.

  • Does underfloor heating mean larger contraction gaps?

    Wood will always strive for an equilibrium moisture level in relation to the air in the environment. Dinesen floors have been dried to 8-10%, and regardless of underfloor heating, they will contract in the winter, when the air humidity is low. With an interior air humidity between 40 and 45% RH, the wood will adapt to a moisture content of 8% wood humidity. If the air humidity drops to 30% RH, the wood will adapt to 6%, which means that it contracts. The underfloor heating does not in itself lead to larger contraction gaps. The higher the surface temperature, the larger the contraction gaps. You should expect the planks to contract by an average of approximately 1% in width, cf.

  • Does underfloor heating cause more warping?

    With seasonal variations, floor planks will warp slightly. That is the nature of wood; it occurs regardless of underfloor heating and is of no concern. Significant warping only occurs if there are problems with humidity levels in the building, or if the construction humidity has not been fully eliminated before the floor planks were installed.

  • Is it possible to achieve a sufficiently high room temperature through thick, solid wooden planks?

    A room temperature of approximately 20 °C is easily achievable. Of course, this requires that the building is correctly insulated, and that you follow the advice and recommendations in Dinesen’s instructions. In older buildings with inadequate insulation, it will often be necessary to have a supplementary heat source.

  • Does underfloor heating make the wood creak?

    If you follow Dinesen’s recommendations for temperature and air humidity, underfloor heating will not make the floors creaky. Creaking often occurs because the joists are too wet, the joists are placed too far apart or the blocking up of the joists is not good enough. However, large variations in temperature or air humidity can temporarily cause individual planks to creak slightly
