Underfloor heating for real wood flooring
Engineered real wood floors can generally be laid over underfloor heating, but only over hot water underfloor heating systems and not over electric heating systems.
It takes time for the heat from the subfloor to reach the room because of the insulating properties of wood.
The so-called thermal resistance of wood must not exceed 0.15 qm K/W, which corresponds to a maximum board thickness of 22 mm.
Low swelling and low shrinkage wood species such as oak are suitable for laying over underfloor heating.
Our multi-layer engineered wood flooring is up to 15mm thick and, thanks to its multi-layer structure, will move less than solid parquet when temperature and humidity changes. This minimises the formation of gaps.

The floating installation of our real wood flooring over underfloor heating impedes the flow of heat, because if the flooring is not firmly glued to the subfloor, air pockets are created which greatly reduce the heat transfer between the heating screed and the flooring. This increases energy consumption as the heat output of the heating system is reduced.
The heating behaviour determines whether a parquet floor feels comfortable on a hot water underfloor heating system.
The surface temperature of the wood must not exceed 25 degrees Celsius.
A cooled room needs time to warm up under these conditions, but the flow temperature should not be increased to avoid minor damage to the parquet. Wood should not be exposed to excessive climatic fluctuations – so the underfloor heating should not be turned up and down all the time.
If these conditions are met, there is nothing to stop a real wood floor being laid over underfloor heating, but you should always be aware of the formation of joints, as the humidity on a heated floor surface is always lower than the air in the room. A humidifier can be used to compensate for the dry air in the room.
