How it works

Three minutes, no tools

No installation, no electrician, nothing drilled. Take it with you when you move.

Lay the underlay
Step 1

Lay the underlay

It arrives rolled. Unroll it where your rug lies: flat, dry floor of any kind, tiles, wood or stone.

Put your rug on top
Step 2

Put your rug on top

Made to the exact size of your rug, so the edges line up and nothing shows. The room looks exactly as before.

Plug in and feel it
Step 3

Plug in and feel it

Any ordinary socket, switch on the cord. Warm in 5–10 minutes, about 40 °C on the surface.

Layers of the Quentex underlay: felt, graphene film, insulation
Under your rug

Your rug, now warm

A 1 cm heated layer made to the exact size of your rug. Nobody sees it; everybody feels it.

≋

Graphene film inside

Turns electricity into far-infrared warmth evenly over the whole surface. No wires to overheat, no fan, no noise.

▭

Felt on top, insulation below

Felt protects the film and spreads the warmth; the insulating base sends it up into your rug, not into the tiles.

✓

CE certified

Tested to EN 60335 (electrical safety), EN 55014 (EMC) and RoHS in an accredited laboratory.

Our honest promise

Why we don’t promise
to heat your room

Portuguese homes lose heat fast: single glazing, uninsulated walls, tiled floors. Heating all that air is a losing battle. So we don’t fight it. We warm you.

01

Radiant, not convective

Infrared warmth goes straight to your feet and body, like winter sun on your skin, instead of heating the air first.

02

Warmth where you live

Cold tiles drain body heat all day. A warm rug by the sofa, the bed or the desk changes how the whole house feels.

03

Honest numbers

About 40 °C on the surface. 520–832 W, €0.09–0.14 an hour at full power. Nothing promised beyond what physics delivers.

Beside the bed

Beside the bed

Warm feet first thing on a January morning, before the house has woken up.

The pets’ favourite spot

The pets’ favourite spot

Cats and dogs find the warm rug before you do. Keep the cord out of reach of teeth.

Evenings on the floor

Evenings on the floor

A book, a tea, a warm rug, and no space heater humming in the corner.

Home office

A heated rug under the desk beats heating the whole room for eight hours. Office chairs are fine.

Rented apartments

Nothing to drill, nothing to explain to your landlord. Take it with you when you move.

Kids’ play floor

Children live on the floor. A gentle 40 °C keeps them there all winter.

Know before you buy

What will it really cost?

Pick your room and size, set your hours. The plan is to scale; the bill is at full power on Portuguese tariffs.

6 h a day

0.17 €/kWh is a typical Portuguese simple tariff with VAT. An optional plug-in thermostat (sold separately) lowers real consumption.

Common questions

Asked honestly, answered honestly

Will it heat my whole room?
No, and we say so before you buy. In a Portuguese home with single glazing and bare walls, nothing under 1 kW raises the air temperature in a way you would notice. The rug warms you: your feet, your body, a zone of about 1–1.5 m around it. The floor stops draining your heat, and that is what changes how the house feels.
Which rug goes on top?
Your own ordinary rug: wool, cotton, jute, low or medium pile. We make the heated underlay to the exact size of the rug, so nothing shows around it. Avoid rugs with a rubber or foam backing: they hold the warmth back. The rug in our photos is not included.
What does it cost to run?
At full power and 0.17 €/kWh: about €0.09 an hour for 155 × 230 (520 W), €0.13 for 180 × 250 (780 W) and €0.14 for 200 × 300 (832 W). Six hours a day for a month is €16–25. Try your own numbers in the calculator.
Can it stay on overnight?
Yes. It is built for continuous use and the surface stays around 40 °C, warm to the palm, never hot. If you go away for several days, pull the plug. Never cover it with a mattress, a duvet or piles of cushions: trapped heat damages the film.
Can furniture stand on it?
A desk with an office chair on castors, yes: that is one of the reasons it exists. A sofa or a table on wide feet, yes. Wardrobes, ladders and anything heavy on thin pointed legs, no: point pressure crushes the layers.
Is it safe with children and pets?
The surface is about 40 °C and the rug is CE certified for electrical safety (EN 60335), EMC and RoHS. Children under 8, and anyone who feels heat less well, should use it under supervision. With pets the rug is not the risk, a chewed cord is: run the cord where they cannot reach it.
How is it made and delivered?
We assemble every rug to order in Cascais: felt, graphene film, insulation, edges, cord, then an electrical test. It takes 3–4 weeks, and it travels rolled; the delivery cost depends on the destination and is confirmed with your order. Details: delivery and returns.
How do I pay?
Send the order request. We reply with the delivery date and a secure Stripe payment link, paid by card, Apple Pay or Google Pay. Nothing is charged before you pay that link.
What happens in summer?
Roll it, never fold it, keeping the roll at least 20 cm across, and store it dry. A sharp fold breaks the film along that line.
My rug is a different size. Can you make it?
Yes. Your rug is another size? We make the underlay to its exact measurements, at about 260 W per square metre of film. Write the size in the order form and we reply with the price.
