A simple Google search quickly reveals a some controversy or at least some degree of confusion among users, about the benefits and advantages underfloor heating compared to the limitations of one of the preferred heating systems in Nordic countries, such as Sweden or Denmark. We refer to underfloor heating electric , an air conditioning option that is already the one preferred by many of our fellow professionals; architects, builders and different technicians of the industry.
Although the concept and design of heating systems electric underfloor heating can cover sheets and sheets of information, we do want to clarify some points that should to be understood compared to other systems that with a cost similar have significant shortcomings.

It is when people do not experience a sensation of heat or cold, there is a balance; that is, when the conditions humidity, temperature and air movements are favorable to the activity that we practice, be it resting at home or be working in our office.
To clarify a bit the comfort concept heat, we can deduce that it is the sensation of “comfort temperature” , which perceives the human body, is not the one that can be measured with a thermometer that will measure the ambient temperature in a space, but the arithmetic mean between room temperature and room temperature average of the surfaces surrounding the body.
This allows us to verify that the human body perceives a sensation of comfort , with a temperature in the environment of 19 °C, when in reality they would be necessary 21 °C to obtain the same comfort through other heating systems (radiators, hot air, etc.). Here This is where the main advantage of the floors comes in. radiant .
To clarify a bit more. In the next image we can appreciate the behavior of the different temperatures – stratification – within a room and the convection and radiation currents of each of the systems (Also more information here). Where the “ideal heating” is the figure 1.
Undoubtedly, underfloor heating is the that has the behavior that most resembles the "ideal heating".
Although technique and technology advance day by day, in terms general we can identify and distinguish three main types:
Possibly the type of heating on soil that more people know and that we will have seen in a way of coil when they place it. the system of
Here, it is electricity that is responsible for heating the system that is below the pavement, which transmits and produces heat in the room.
An example of the component parts:
We can say that this system is the most modern, where the heat is transmitted by filaments of fiberglass carbons installed under the floor.
In view of the different types of underfloor heating there are two important points to remember:
We must also remember that before proceeding to any installation, always ask a professional sector to answer any questions.
Which flooring is best for a house with radiant?
Actually, you can use both ceramic floor tiles and wood laminates. Strictly ceramic floors always have better performance compared to the typical wooden platform since They have a better conductivity coefficient. In the case of use pavements and wooden floors will have to have special features. It is best to ask in store and see the technical characteristics of the product.
When we talk about markets and competition, the environment becomes becomes rare and acts a kind of "anything goes" in which they put hoaxes and false beliefs in circulation with the aim of push—or sink—products and services over the world of slab or radiant floors.
Advantages of shaped underfloor heating direct:
In the case of this type of heating , and in especially the electric underfloor heating , it happened something similar and erroneous ideas were created that were They became myths. However, professionals air conditioning and energy efficiency sector have spoken. Together with them, we will dismantle the 4 most extended and we will see its advantages .
The advantage of underfloor heating is based on the distribution of heat from bottom to top, emulating the ideal heating (increasingly, upwards) achieving very significant energy savings.
Of the following two graphs we identified; the first is the relation of costs and investment compared to other systems and the second, the percentage savings in consumption compared to other teams:
It is very possible that when thinking about an installation of radiant floors in greater surface we associate higher energy expenditure. However, the reality is far from of this approach. In this process almost the Half of the energy is emitted in the form of radiant heat from low temperature, which is distributed evenly uniform . In addition, if we use equipment of aerothermal energy also help save.
Savings come precisely from low-cost issuance temperature and the proportion of the body surface emitter, which achieves an optimal sensation of warmth and comfort using much less energy and therefore cutting the invoice up to 20%. (See article on tips to save heating electricity from here, with more than 30 tips)
A priori, it may seem that opting for this system in instead of other heating systems is to choose the option with the highest cost. However, the proven savings energy that we pointed out in the previous point makes us pay off the investment year after year year thanks to the cut in our bills.
We must remember that the implementation is simple, although we could say that one of the disadvantages of the soil radiant is that you have to be very precise in the dimensions of concreting in the slabs and precautions with the timely reconsideration of the partition.
But realistically, this is actually transferable to any work and operation on a work, being professionals at work is a must.
Nothing could be further from the truth!... And it is that among the advantages and disadvantages underfloor heating premium plus its usefulness and efficiency, moreover, it is the only recommended by the World Health Organization (WHO).
It has been believed that by radiating heat from the pavement, the radiant heating could be detrimental to the system circulatory system (favoring the appearance of varicose veins), but it It is true that it is innocuous if it is well regulated; that is, if not exceeds 24°C or 25°C. On the other hand, thanks to the uniform convection of the heat ,
Specialist technicians and installers ensure that the Installation of this heating system is not complex, it is adapts to any type of floor (parquet, marble, ceramics…) and can be placed quickly without specific work.
The companies that market it offer a wide range of cable and mesh solutions that adapt to any area, also including alternatives to not increase the height of the ground.
As we have seen, information is essential. That's why, when choosing a heating system for our home it is recommended that we let ourselves be advised by experts in air conditioning, who will know how to assess the technical requirements of our home to achieve the greatest comfort with the minimal expense.
