Innovative heating system: radiant panels
An innovative system to heat our indoor environments is represented by the so-called "radiant". The "mission" at the base of its operation is easily summarized: to maximize the surface area of the heat emission, reducing the operating temperature of the system. For this, the radiating system is composed of pipes inside which water is circulated to the average temperature that can go from 30 to 40 ° C, which are "spread out" over large surfaces radians. The material they are made of the tubes can be polyethylene, polybutylene, polypropylene, or copper, and the geometry of the laying to be preferred is that defined "spiral" or "spiral" in which the circuit of water flow is parallel to that in output of the same.
Underfloor heating systems
There are several ways of implementing a radiant panel system, linked to the type of structural support that can be used: floor, wall, ceiling.
or implants are the most common in the floor, in which the circuit can be allocated to both under the support layer (substrate), either drowned in the same or in a leveling layer between a double layer of separation. A floor system ensures optimal level of BIOCOMFORT thermal: the heat is evenly distributed over the entire surface without leaving gaps, thermal as in the case of traditional systems punctiform such as traditional radiators; allows a great saving of energy and therefore economic: the low operating temperatures considerably reduce the cost for heating in winter, does not involve any constraint for furniture, keeping in mind, however, that it would be advisable to prefer natural flooring (eg cooked) and avoid "choke" insulating materials (eg rugs or carpets).
In the plant or wall pipes are housed in the outer wall, directly attached to the insulating elements and covered with cement plaster on which we will proceed with the work of finishing. The radiating surface required by the system to the wall is directly linked to the design temperature (greater than in the case of the floor); generally quantifiable equal to 1/2 or 1/3 of the entire floor area. This type of system than the floor is easier installation, provides a higher level of thermal comfort, requires a speed-up load, lower and conversely presents major constraints for the layout of the furniture. An interesting variant of the radiating system wall is constituted by the so-called "radiant baseboard". In this case, the water is circulated within microtubes copper places inside a support aesthetically similar to a traditional baseboard, and the heat produced, licking the support wall, as this will be, transferred slowly to the environment internal. Due to its ease of installation, rapid and non-invasive, this type of system is highly suitable for retrofitting.
The plant or ceiling, in its most common version, is composed of modules of metal or plasterboard inside which are housed the pipes. The modules are fixed directly to the insulating elements using special clips and are joined together by the pipes themselves. A more advanced version of this type of system is constituted by the so-called radiant fed by an external burner. The radiant ceiling system presents no practical constraint, and, spreading heat by radiation, it is not absolutely correct to think that its location at the top espleti not function well in their "heating". For this reason it is highly used in very large environments such as industrial warehouses and the like. The only disadvantage is the operating temperature of which can never be too high for the health of the users concerned parties.
A radiant system, regardless of where it will be located, is an advantageous system for the heating of all those environments, especially of long permanence, practical and economical, especially if powered by solar thermal and / or condensing boiler.
