OLD SYSTEMS

The old realizations of years ' 50 and ' 60 previewed use it of a tube in low-carbon steel that came drowned in the solai to heat. Not previewing moreover some type of isolation towards the bottom and the external walls, systems with a most remarkable thermal inertia were obtained, of difficult management and with skin temperatures on the pavements beyond the limits of the comfort, poichè elevating (around to the 70°C was demanded one temperature of exercise of the termovettore fluid much). That was often cause of circolatori problems, capogiri, nonchè probable concomitant cause of the insorgence of varicose veins.

The new systems in commerce preview instead use it of materials of new conception, with a system called "to isolated floating pavement" towards the bottom and the walls. That has concurred of having a temperature of exercise of the inferior termovettore fluid to the 40°C, with a remarkable energetic saving, and obtaining a flexible system to medium inertia.
