How do Radiators work?
  • The heat source heats up the water in the boiler.
  • From there, the water travels to the radiators and transfers its heat to the radiator material, which is usually metal, a good conductor of heat.
  • The radiator then transfers its heat to the air, and that’s where convection comes into play. Thermal convection is based on the natural law that hot air rises and cold air drops.
  • As the radiator warms the air around it, that warmed air rises and flows into the room.
  • At the same time, the cold room air drops to the floor and is drawn toward the bottom of the radiator, where it becomes heated.
  • This hot-and-cold rotation naturally heats the room without the need for circulation fans or other mechanical means.
  • All standard hot water radiators have an inflow pipe and an outflow pipe, and many have some kind of temperature control for adjusting the flow of hot water through the radiator and thus the heat it puts out.
  • Radiators require a flow temperature of around 80°C flow and 70°C return.
  • Feel comfort by controlling the temperature of each radiator with a Thermostatic Head.
Advantages of heating with radiators
  • Radiators are appreciated for their simplicity and their relatively unmatched ability to evenly warm up spaces.
  • As the radiator has evolved, it has taken on a variety of shapes and sizes, and now has a design value on top of its practicality.
  • One of the safest types of heaters, radiators do not require any other materials like wood, coal or oil for continued use, unlike gas heaters, for instance, that must be used in well-ventilated areas.
  • Radiators maintain their heat well and although they are more efficient when uncovered, many people use them as an extra way to dry clothing especially wet towels and bathroom mats.
  • Radiators are convenient as they can be easily switched on and off (now even remotely by mobile phone!)  and only turned on in the rooms of your home that you use.
  • Faster Heating
  • Easily switched on and off
  • Only Turned on in the rooms of your home that you use
  • Variety of Shapes and Sizes
  • Design Value

Aluminum Radiators, FARAL, Italy



  • TROPICAL represents the perfect synthesis of FARAL radiators!
  • TROPICAL was the first die-cast aluminum radiator in the world and, like any self-respecting record, it was a model to imitate for many others.
  • This only information may be enough to communicate this product’s prestige and importance, but its success shall also be conferred to the ease of installation and the thermal performances!



  • ALLIANCE: aluminum and technology combined to create harmony and comfort.
  • A synthesis of design, functionality and performance.
  • Its surfaces, which are tip-rounded, make ALLIANCE the most aesthetically appreciated radiator.


Height = 146 cm


  • Tropical+ is equipped with optimum fluid dynamic geometry which directs the flow of hot air output, in the most effective way.
  • The high thermal efficiency combined with a modern aesthetic, allows Tropical+ to make every room unique and moreover it can be perfectly combined the classic Tropical.
  • Radiators are assembled from 2 to 6 elements.
Aluminum Towel Warmers, NEXT HEAT, Italy

Piping (between the manifold panel and the radiators), Valsir, Italy
  • Heat performance
    • The presence of the aluminum layer, its thickness and position, result in excellent heat conductivity characteristics.
    • With Mixal®pipes it is possible to carry out floor heating systems with higher heat outputs.
    • In fact, the greater conductance generates higher temperatures on the pipe surface as compared with all-plastic pipes (PE-X and PERT) and this advantage is reflected, for example in the possibility of obtaining relatively low supply temperatures.
    • The greater performance of Mixal®pipes compared with all-plastic pipes means greater system output at equal flow conditions. An example: the 16×2 Mixal® pipe has the same thermal output as the 17×2 PE-X pipe.
  • Mechanical behavior
    • The mechanical characteristics of the Mixal® pipes make them ideal for use in floor heating systems. The bending radius corresponds to 2.5 times the pipe diameter and the circular section at the bend remains constant.
    • The pipe, once bent, remains in the desired position like a metal pipe; hence the use of anchor clips is not required as with all-plastic pipes.
  • Barrier against oxygen and UV rays
    • The inner layer in aluminum acts as a perfect barrier against the passage of gaseous molecules thus avoiding the danger of corrosion due to oxygen infiltration and damage caused by exposure to UV rays
