The work force of the radiant floor must belong to a high range, so that the heating level is much more efficient. Going through the shopping lists, you will find products with a power of 100, 150, 450, 2,000 and even 4,000 watts. Of course, this decision depends on the size of the room or corridor of the house that we want to heat.

In addition, this specification necessarily leads us to ask ourselves other types of questions such as the required current input, which is generally a maximum of 240 volts. In the same way, its energy classification must be known, which will help us to know if it is an environmentally friendly product, and it is therefore recommended that it be an A+++ efficiency. This is how you can save up to 40% energy.


It is important that you check if the selected radiant floor incorporates a thermostat. This device, although it can probably influence how much the product costs, is considered a long-term investment, since it will help you control the operation of the heating in a simple way.

The quality indicators to specify in this device would then be, first of all, its size, which must be compact and light for correct handling and installation.

Frequently asked questions

Q1: How to purge underfloor heating?

The first thing you have to do is check if your model incorporates an automated purging mechanism. In this case, you will only have to turn said key and wait for the process to be carried out. With regard to floors that do not incorporate this system, then you will need to perform the purge manually.

To do this, you must open the valves one by one, wait for all the air to come out, activate the pump at a pressure of at least three bars and, when the water comes out, then the purge will be finished. This may take approximately five minutes.

Q2: How to clean underfloor heating?

You must remember that this connection system is located under the ground, so it does not require special care. What you can do is check both the status of the valves and the thermostat, being necessary to seek the help of an expert to carry out a thorough maintenance of these parts.

With regard to the surface of laminate, parquet, tile, wood or other material that covers the heating system, you can clean it according to your own needs. This means that you will have to sweep, vacuum or mop with a specialized cleaning product.

Q3: Can I install underfloor heating without a thermostat?

When it comes to underfloor heating, the recommendation is to accompany it with at least one thermostat, since, in this way, once the resistances or probes have heated up, you can adjust said temperature. In this way, it will be possible to maintain warmth throughout the day if you wish. In addition, you can install a thermostat in each room, in order to adjust different heat levels, according to the needs of each space.

Q4: What spends more, underfloor heating or radiators?

Radiant floors are definitely the most economical option with regard to energy consumption, since they work through a low temperature circuit that ranges between 30 and 45°. This means that they consume up to 20% less compared to traditional cut radiators, which require between 80 and 85° of temperature to offer efficient performance, but with higher consumption.

Q5: Is underfloor heating compatible with parquet?

Parquet is a type of wood with a series of natural properties, capable of achieving optimal thermal insulation, which is quite flattering to make the most of the temperature generated by the set of probes that make up the underfloor heating.

In this way, by using said material as a coating, you will not only considerably reduce heat loss and achieve a homogeneous spread of heat, but you will also be saving energy and, therefore, lowering costs in monthly electricity billing.

Q6: How to regulate Uponor underfloor heating?

The regulation of the temperature of the radiant floor through this wireless technology is very simple, being only necessary to link your smartphone through an Uponor application, in order to be able to control the programming of the on, off and adjust the different temperature levels remotely and from the comfort of your mobile.

Of course, this technology is applied to the thermostat, which is in charge of carrying out these functions manually. Some models even incorporate a remote control, so you can carry out this procedure by pressing a couple of buttons, from any angle in the room.

Q7: Which is better, underfloor heating by water or electric?

Both types of flooring offer effective and safe operation, with some distinctive differences between them that do not make them better or worse than one another. The radiant water heating system has lower energy consumption, but requires more accessories at the time of installation, which means a greater investment than installing an electric floor. The latter is cheap and quick to assemble. However, its power consumption can be a bit high.

Q8: What is underfloor heating?

When we talk about cooling radiant floors, we are not only referring to a heating mechanism, but to a more complex and comprehensive system, capable of air conditioning the different rooms of your home. This means that you have at your disposal equipment that adapts to any season of the year, since you can adjust it so that it radiates heat in winter and cold in summer.

Q9: How does gas underfloor heating work?

Gas radiant floors work based on a work cycle combined with an electrical system. In this way, once the current is produced, it is immediately transformed to a high voltage range and then passes to a low voltage. During this process of changing the voltage, up to 50% of energy is lost, which registers only 25% of the consumption of the primary start-up in each user’s meter, being a very economical option.

Q10: What is more convenient, underfloor heating or aerothermal?

The main function of underfloor heating is to provide the necessary heat to set the different rooms in your home, so they are suitable for the winter season. Likewise, other models serve as air conditioners, providing a little more versatility.

For its part, the aerothermal system works with the help of a heat pump to provide you with a heating mode and a cooling mode, being possible to connect it to some type of heat generator to produce hot water. Both options are recommended, but finally the selection of the product depends on your needs.

Q11: Which is better, underfloor heating or wall heating?

Perhaps at first glance you might think that a radiant floor generates a much higher level of heat than a simple radiant wall, since the latter occupies a much smaller space when installed.

Recent studies have concluded that the installation of only 20% of the radiant slab on a wall in the room emits the same range of heat as installing 100% of the product on the floor of the same room. In this way, when mounting on the wall you will be saving work time and money.
