Most Dubai homes do not have underfloor heating. We live in a hot climate; nobody is heating their feet in July. But a small and growing number of villas, particularly the larger ones in Emirates Hills, Al Barari, and some of the newer Marina developments, do include UFH in bathrooms, kitchens, and occasionally living spaces.
If you have it, or are thinking about it, the floor you choose matters. Here is what we have learned the hard way.
Compatibility is not optional
Engineered wood is fine on UFH but only with the right system, the right adhesive, and the right acclimatisation. Solid oak is not safe at all; the timber moves too much across the seasons and will eventually cup or split.
SPC is compatible with UFH up to a surface temperature of about 28 degrees Celsius. Most domestic UFH systems run between 22 and 27 degrees, so you are fine. Push past 28 and the SPC core can warp, the lock joints can fail, and the manufacturer warranty quietly stops covering you.
LVT depends entirely on the brand. Some are rated to 27, some to 28, a few not at all. Always ask for the specific UFH rating, in writing, before you order.
The bit that catches people out
You cannot turn UFH on for the first time the day after the floor is installed. The system has to be ramped up over a fortnight, in small increments, to let the subfloor dry out and the timber or composite settle without shock. We have seen brand new floors lift completely because the homeowner cranked the heat to 25 on day one.
The right sequence is roughly this: install the floor, leave the UFH off for 48 hours, then bring it up by no more than 2 degrees per day to your target. Down-ramp the same way at the end of the season.
One more thing
Underlay choice matters here as much as the floor itself. A standard 2 mm foam underlay does not conduct heat well; it acts as an insulator between your UFH and your feet, which defeats the point. For UFH installations, use a specific thermally conductive underlay rated for the purpose. Costs marginally more, works dramatically better.
If any of this sounds vague when a contractor describes your project to you, push back. UFH compatibility is the single most common reason a flooring install fails in the first year, and almost every failure is avoidable.
