The advantages of parquet with underfloor heating
Underfloor heating and parquet flooring - is that even possible? We'll tell you what you need to know.
There are few things nicer than coming home after a long walk in the woods and feeling a cozy, warm floor under your feet. More and more people want underfloor heating. However, this type of heating not only ensures a pleasant living climate, underfloor heating also helps to save energy. A parquet floor over your underfloor heating provides additional living comfort and natural coziness in all rooms. If you're wondering whether a real wood floor and underfloor heating are a good match, we can give you the green light. Our modern engineered parquet is suitable for installation over underfloor heating. This has even been confirmed by extensive scientific research by the Fraunhofer Institute. Incidentally, the same also applies to underfloor cooling under your floor covering.
Which parquet is suitable for laying over underfloor heating?
Thanks to modern manufacturing processes, you can have more and more types of wood laid over underfloor heating. Our multi-layer parquet even has such favorable heat transfer resistances that no wood species has to be excluded. Even wood species such as beech are approved for use on underfloor heating at HARO. A wooden floor also saves energy, as the heating can be switched on later and switched off earlier, as wood dissipates its own body heat less effectively and the floor feels inherently warmer. In general, the radiant heat of underfloor or wall heating is also considered to be healthier and more pleasant because, for example, the (cold vs. warm) air currents of convection heating stir up dust and dry out the mucous membranes.
As our entire parquet range is suitable for installation over underfloor heating, you don't have to limit yourself when it comes to designing your home. Our extensive selection of parquet flooring is guaranteed to have the right floor for every taste. So in addition to warm feet, a trendy look is also guaranteed.
You get the greatest advantage from multi-layer parquet and the associated crosswise gluing of the layers. Multi-layer parquet also offers a conditionally higher dimensional stability with regard to joints and deformations.
For the love of nature
With underfloor heating, you not only ensure pleasant warmth in all rooms, but also protect the environment by using energy efficiently. Compared to conventional heating, the room temperature can be kept around 3 °C lower with underfloor heating without you noticing any difference. You can imagine how much energy you save each year. Nature and your wallet will be happy in equal measure.
You are already demonstrating environmental awareness with your choice of multilayer parquet. Because in contrast to solid wood flooring, modern prefabricated parquet uses far less valuable natural raw materials. From one cubic metre of oak wood, approx. 115m² of multilayer parquet can be produced, but only approx. 35m² of solid parquet.

How to install your underfloor heating under parquet
Now it's getting serious! We'll tell you how to install the heating under your parquet. Suitable systems for installation under HARO parquet are hot water, infrared, panel heating systems made from prefabricated elements and electric underfloor heating systems (excluding night storage heating systems).
The screed for your underfloor heating must be prepared professionally. To ensure that the screed dries properly, the respective drying times should be observed. These are generally at least 21 days for cement screed and at least 7 days for calcium sulphate screed (anhydrite). This is followed by functional heating, which lasts at least 7 days in each case, and the ready-to-cover heating with a duration of at least 7, but usually 14 days. In total, this results in a drying time of at least 35 days for cement screeds and 21 days for calcium sulphate.
The heating process is started at a temperature of 25 °C. The flow temperature is then increased by 10 °C every day until 55 °C or the intended maximum flow temperature is reached. Heating now continues for 11 days at 55 °C or the intended maximum flow temperature without night setback. After this, reverse gear is engaged and heating is reduced by 10 °C daily until the initial 25 °C is reached again.
The screed must now be checked for residual moisture using a CM device. If the measured values are less than or equal to 1.8 CM % for cement screed and also less than or equal to 0.3 CM % for calcium sulphate screed (anhydrite), the floor is ready for covering and the parquet can be laid.
If the floor is not yet ready for covering, please be patient for a few more days and continue to heat the floor at maximum flow temperature. If dummy joints and cracks appear in the screed, these must be filled with a two-component synthetic resin - regardless of whether your parquet is laid floating or fully bonded.
When the screed is completely dry, your beautiful new parquet can finally be laid on the floor. The surface temperature of the screed should be at least 15°C, the room temperature 18°C and the relative humidity a maximum of 65%. Once your parquet has been laid, this climate must be maintained for a further five days.
From now on, you can enjoy the pleasant warmth of your underfloor heating and the elegant look of your parquet.
Summer can come
There's hardly anyone who doesn't enjoy the soothing warmth of summer. But let's be honest, when it's really hot outside, cooling from below can't hurt. Why not try underfloor cooling? In summer, your underfloor heating - as long as it is operated with water - can also provide refreshing cooling. This only requires a few additional or functionally enhanced components
Our HARO brand floors are easily suitable for installation on underfloor cooling. To prevent condensation from forming on the surface of your new parquet, all you need is a dew point monitor integrated into the cooling system control unit. And then you can enjoy cool temperatures in all rooms during the summer months.
Whether underfloor cooling or heating, our "Made in Germany" brand parquet can easily be combined with both. It doesn't matter which wood your heart beats for.
Fancy some high-quality design variety?
All our modern parquet floors can be laid floating or glued down over underfloor heating. Simply decide which parquet suits your personal style best.
