FAQ

It works through a glass resistance with nanoparticles, coupled to a natural stone. The heat is stored in the stone and radiated into the room, being controlled by a thermostat.

It provides thermal comfort, doesn’t dry the air, is energy-efficient, easy to use, eco-friendly, and has high durability with a 10-year warranty.

Yes. Our radiators are safe for environments with children. They reach temperatures that do not cause burns with brief contact and can be installed in higher positions, out of children’s reach. They emit no gases and do not dry the air, making them a healthy and risk-free option for the whole family.

It’s simple: fixing the radiator and thermostat on the wall, electrical connection, and programming. It takes between 45 and 75 minutes.

It can be used in any room, from small bathrooms to large living rooms, adapting to different types of housing.

The radiators last for decades. We offer a 10-year warranty on production errors, and many customers report continuous use for over 20 years.

Yes. You can choose from various types of stone, finishes, colors, paints, textures, and other aesthetic details.

The average cost ranges between €50 and €70, depending on the location and the number of radiators. It includes materials and labor.

Yes. We deliver and install throughout the country and in parts of Spain. We have teams of sales managers for technical and commercial support.

Small: 375W (60x40cm) | Medium: 650W (100x40cm) | Large: 900W (100x50cm)

Not necessarily. With the right equipment, it is possible to locate and repair faults locally without breaking the entire floor.

Yes. We have several options with white or black mirrors.

he underfloor heating has water-proof protection. The cables are resistant, but the thermostats may be affected. A technical inspection is recommended.

Yes! The system can be installed during renovations. It’s important to assess the type of existing flooring and the insulation of the house to ensure optimal performance.

Yes, electric underfloor heating can work as a primary or supplementary system, for example, together with natural stone heating or a radiant block built into the wall.

Yes! We offer smart thermostats that allow you to control the temperature remotely through a mobile app.

Yes. The system allows individual control per room, providing greater comfort and energy efficiency.

No. When installed with good insulation and programmable thermostats, consumption is efficient and can be more economical than traditional systems.

Yes, electric underfloor heating is fully compatible with photovoltaic systems, allowing you to maximise solar energy use and reduce costs.

Don’t worry! Our system is designed to make both maintenance and possible repairs easy. In the event of a failure, the issue can be located and resolved precisely, without having to lift the entire floor. We also offer specialised technical support to ensure a quick and hassle-free service.

With proper installation, the system — especially the components under the floor — can last over 30 years without maintenance.

Yes. Heat is distributed evenly and safely, with no exposed parts or risk of burns.

Absolutely! One of the main benefits of underfloor heating is consistent thermal comfort — perfect for walking barefoot all year round.

A radiant block is ideal for spaces where constant comfort is desired with minimal temperature variation, such as bedrooms or living rooms. It’s also a great choice for energy-efficient homes.

Yes, it can be controlled via home automation systems using compatible thermostats, allowing remote management and better efficiency.

No. The design is compact and discreet. It is installed inside the wall without compromising interior design.

On average, it starts to release comfortable heat 30 to 60 minutes after being switched on and continues to heat even after being turned off thanks to its thermal inertia.

Yes, as long as the installed power matches the size and insulation of the room, it can serve as the main heating system.

No. The stones used are carefully selected for their thermal resistance and are perfectly suited for electric heating elements. Additionally, professional installation ensures a safe and long-lasting setup. Even so, if heat damage occurs, Duo-Thermo’s warranty covers this within the specified terms.

No. With regular use, the stone retains its original appearance. A simple wipe with a damp cloth is enough to keep it looking beautiful.

Yes, the system is electric and compatible with solar energy, allowing for eco-friendly and cost-effective heating.

Yes, although it requires technical assistance to ensure the electrical installation and mounting are done correctly in the new location.

Yes, we offer dedicated models with dual function — they heat the space and also serve as stylish towel warmers.
