3. Low-inertia residential

systems

RENOVA system, bonded

The bonded RENOVA System is designed for radiant systems

with low-thickness screed and thus low thermal inertia.

Created specifically for renovations, with applications over

existing floor coverings, its use is also being extended to

new housing, particularly in low-energy-consumption homes,

precisely because of its low thermal inertia (see the introductory

section "Underfloor Radiant Systems").

The system is realised through the combination of the special

RENOVA panel with special high mechanical resistance screeds,

for which the panel has been specially designed and for which

Wavin Italia SpA has carried out a series of tests with reference

to the Technical Construction Standards of the Ministerial

Decree 14 January 2008.

This combination allows extremely reduced thicknesses above

the pipe (10 mm) providing the system a number of advantages:

•

Low system thickness: 31 mm + covering;

•

Economical realisation: the low thickness allows

installation over the existing floor, avoiding demolitions;

•

Low thermal inertia: thanks to the reduced thickness,

the system comes up to full capacity quickly, making the

system particularly suitable both for heating and cooling.

•

Energy savings: thanks to the low thermal inertia, but also

to the use of standard 17-mm pipe, for which the system

was designed, one avoids the higher power consumption

of the circulators due to the typical pressure losses that

would otherwise occur in smaller diameter pipes.
