Underfloor heating (Radiant heating more specifically) is a solution more and more used in new homes, so the energy resources, more and more scarce and expensive, can be effectively used.
It was an invention of the ancient Romans, who made convey hot air under the floors to keep the spa warm and welcoming. Today this system has reached a fully mature technology with a superior efficiency to the traditional radiators present in most of our homes.
The operation is allowed by a coil of tubes in which water flows at a temperature of about 30 ° -40 ° (the heaters have a normal temperature of 70 ° -80 °) These tubes are connected to the boiler that heats the fluid. The slab in the inner part, in contact with the structure, houses an insulator which does not allow the passage of heat toward the lower floor but only to the environment to be heated.
An Underfloor heating has as greater advantages the minimum heat loss and a constant heating over the entire surface to be heated, while the main disadvantage is the higher construction costs of the pavement.
It is a cost which can be 50% greater than the one of a typical radiators system, but the advantages are: more space in the apartment, lower energy consumption, constant and balanced heat all over the space.
A room with no radiators on walls looks larger and less dense and it’s also easier to decorate. Moreover, underfloor heating can help to reduce the humidity content of a room and that can be especially beneficial for those suffering from asthma who can endure the problems caused by dust mites, which thrive in humid environments.
Underfloor heating Advantages
- Lower temperature (30° -40 °) with associated energy savingsPotential in applying solar panels straight to heating
- The great possibility of using condensing boilers instead of compensation ones
- Uniform and constant temperature
- Larger surface area available due to the absence of radiators
- Reduction of convective motion that moves dust
- Absence of hot air at the top and air at the ankles level
- No more dust combustion
- Adaptable technology for summer cooling
Underfloor heating Disadvantages
- Greater realization cost compare to the traditional systems
- Slowness in bringing to room temperature the space to be heated
