Frenquently asked questions 

Underfloor heating is the only air-conditioning systema recommended by the WHO. It is characterized by being the most efficient and economical for heating and cooling single-family home, residential buildings, renovations, industry, offices, agriculture and livestock.
It consists of a closed system of pipes evenly distributed over the entire surface of the floor, through which water circulates at a low temperature to achieve a pleasant and homogeneous temperature, both in summer and winter. It does not dry out the interior of the house, does not produce draughts and does not take up wall space.

In homes: both individual and communal in new construction or renovation. In buildings: offices, factories, nursing homes, hospitals, kindergartens, schools, universities, churches, industrial buildings, museums, animal kennels, dog kennels, hangars, hotels, stores, etc.

Sports facilities: gyms, sports centres, pools, high-performance centers, tennis and paddle courts, soccer fields, yoga rooms, meditation, pilates, common areas, locker rooms, etc.

Outdoors: access ramps, pedestrian areas, in parking lots, passageways, and stairways as anti-ice systems, animal shelters, sidewalks, etc.

The main advantages are: healthy, invisible, safe, comfortable, reliable and clean. Without forgetting its high level of efficiency due to its high inertia, which allows it to be kept in operation for a longer period of time with hardly any need for energy input.

One of the main advantages of underfloor heating system is the savings on your energy bill, which can be between 10% to 60 % in comparison to other heating systems, working at a temperature around 35 °C, while other systems such as radiators require 65-75 °C . So you can save on your bills with underfloor heating!

Which is better, underfloor heating or radiators?

Both heating systems require some work for installation, but a radiator heating system is less demanding than an underfloor heating system. However, the latter provides us with considerable energy savings in the bill, a homogeneous distribution of heat, without leaving any element in sight, allowing us to divide the heating into rooms and also being able to regulate each of them independently. 

Underfloor heating maintains the natural humidity in the room, preventing the generation of dust and dust mites, while radiators tend to reduce not only the humidity but also the oxygen level.

Yes, it is possible and it is the perfect combination to enjoy maximum comfort all year round. With the same polythermal system you will be able to regulate the temperature of each room both in summer and winter.

Within the underfloor heating systems, there is the electric floor and water underfloor heating, as the system par excellence due to all its advantages.

The electric underfloor heating has a conductor cable that is distributed throughout the room homogeneously, working as its name indicates with the electricity supply. To provide us adequate comfort, the electrical power you need will be high, so the expense will also be.

On the other hand, the underfloor heating by waterworks is hot or cold water which circulates through a closed circuit of pipes that is under the pavement. This modality of air conditioning is the one that presents the most benefits for its efficiency and well-being, the only heating system recommended by the who because it does not generate currents, maintains environmental humidity, prevents the transmission of air particles, and provides a homogeneous temperature that generates the best feel-good feeling, working with such low temperatures and having so much inertia, the savings will be considerable, even more, if we combine both sustainable and efficient energy generators..

The underfloor heating system consists of a network of pipes installed under the floor in any room, on top of a layer of mortar that helps the circulation of hot or cold water covering the surface area, causing a temperature suitable throughout the year.

Once we have decided on an efficient and quality heating system, we must decide on the floor. In this section, if you have always dreamed of but you think it is not compatible with underfloor heating, do not worry, because all types of flooring are compatible with this heating system,
But we must differentiate between some types of flooring and others, since, depending on the thermal resistance of each one, the performance will vary. We find the petrified screeds as the most suitable for installation on a radiant floor due to their low thermal resistance. On the other hand, the thicker the wood floor, the greater the thickness, the greater the resistance, and the lower the performance of the installation
