Hello everyone,
I am planning to place an IKEA KALLAX shelving unit directly on top of underfloor heating in my new living room. Now I wonder if this works well in practice or if there are potential issues I should consider. Specifically, I am interested in:
How does the KALLAX unit behave in terms of materials when exposed to the heat from the underfloor heating? Can direct contact with underfloor heating negatively affect the carcass or the back panel (such as warping, deformation, or even damage)?
It would also be interesting to know whether the insulation and construction underneath the KALLAX significantly reduce the efficiency of the heating or if the furniture noticeably diminishes the heat output into the room.
Does anyone in the community have experience with KALLAX combined with an active underfloor heating system over the long term, or is it better to place the furniture with some distance from the heating? I look forward to technical assessments and practical advice!

great question you’ve raised! 🙂
I have my KALLAX partly placed on underfloor heating, and honestly, so far everything is working perfectly. The material of the KALLAX is mostly MDF-based with a thin coating, so you can feel some warmth, but nothing that looks like it would cause warping.
What I’ve noticed is that the area right next to the furniture is slightly cooler, but it’s not a big issue. The heat spreads through the air anyway, and underfloor heating usually runs at a moderate surface temperature (around 29–31 degrees Celsius (84–88°F)), which the KALLAX handles easily.
You might just want to make sure there’s no extremely hot air or direct heat sources underneath. A little gap (for example, using small felt pads) usually doesn’t hurt—the cost is minimal, and it adds some extra safety. Also, don’t forget about dust buildup under the shelf, as it can accumulate there a bit.
In short: I’d say it works well, no need to panic, and good luck with your setup! 🙂

Hello fada47,
First, regarding the material: KALLAX mainly consists of wood-based materials (MDF/particleboard). Such materials can be prone to increased drying, warping, or cracking when exposed to constant direct heat. The surface temperature of underfloor heating usually does not exceed 29-31°C (84-88°F), which in most cases remains within the acceptable temperature range for these materials.
However, placing it directly on the heated surface should be viewed critically, as the heat trapped inside the furniture has limited ways to escape – which can lead to moisture and temperature spikes.
Another factor is heat output from the floor. When covered by furniture, the local heat emission decreases. KALLAX with closed sides and a back panel not only blocks radiant heat but can reduce the heat transfer effectiveness locally by up to 20–30% due to the material thickness.
Conclusion: Using a small gap or insulating/spacer material can prevent deformation and improve heat dissipation. Alternatively, it is advisable to place the KALLAX against a wall or on legs so that at least a small space remains free between the furniture and the heated surface.

Hello fada47,
I would like to answer your question in more detail, as several aspects come into play:
1. Material and temperature tolerance:
The KALLAX shelf unit is made of MDF and particleboard. These materials are stable under normal ambient temperature and humidity conditions. Underfloor heating systems have a relatively low surface temperature (max. about 29-31°C (84-88°F)), which should generally not be a problem.
2. Continuous heating and moisture:
A potential issue is prolonged exposure to heat, especially if localized hotspots occur or if there is no air circulation. This can lead to slight warping or drying out of the wood-based panels.
3. Heat emission and energy efficiency:
The cabinet acts as a thermal barrier, particularly the back panel. This reduces the effective heating surface and causes some heat to be retained in the furniture or reflected back into the floor.
My recommendation:
- Use a thin, heat-resistant mat between the KALLAX and the floor, such as felt pads or a thin insulation mat, to minimize direct heat transfer.
- Ensure some air can circulate underneath to prevent condensation and dry “hotspots.”
- Position the shelf unit so it does not cover the entire heated floor area.
In summary, placing a KALLAX on underfloor heating is possible if a few details are observed. Without these precautions, the furniture may be damaged over long-term use, or the heating efficiency may be reduced.
I hope this helps! Feel free to ask if you want to know more about specific heating systems or insulation techniques.
