ECOFLOOR TECH panel is combined with a
PE-RT14x2 pipe. With it it it is possible to realize
longer circuits compared to low thickness radiant
systems using 10 mm tubes reducing the number
of connections to the collector and therefore the
costs of the system.
LONGER CIRCUITS WITH PE-RT PIPE 14x2 mm

27. Low thickness: Advantages
● Quick heating when starting
(only 1 hr compared to 5 hr in traditional systems)
● Better response to thermoregulation
● High performance due to high conductivity and low thickness
● -3°C supply temperature compared to traditional systems
● Better heat diffusion because the self-levelling screed adheres well

28. Faster construction sites
● Light and small panels
● Highly footfall resistant shell
● No need of anti-shrinkage nets
● Absence of joints and crack-resistant mesh
● Quick drying and start-up within a few days (4 days or as recommended)
● 40% Cost savings compared with a “dry” radiant system

31. PRE-CONDITIONS
Make sure that the following conditions are met before proceeding:
● Internal plaster is finished
● Structural height has been verified
● Electric and hydraulic sistema are finished
● Niches to place the manifolds have been made

32. PRE-CONDITIONS
The support surface must be:
● Flat
● Load-bearing
● Stable and compact
● Clean

33. Possible support / subgrade
● Cement-based screed
The substrate must be dimensionally stable and mechanically resistant according to the
intended use of the floor. The surface must be cleaned of dust, dirt and grease and any
cracks must be compensated to restore integrity and flatness.
● Lightened pre-screed
It must be stable, compact and with good compressive strength.
● Existing ceramic or stone cladding
Check, by tapping, that the covering is well fixed: any detached tiles must be removed
and the flatness of the support must be restored.
● Wooden, PVC, linoleum, rubber or other cladding
These coatings are not suitable to receive the ECOFLOOR TECH radiant system so they
should be removed together with the adhesive residues up to the support layer.
● Acoustic insulation
In this case, contact the technical office of the acoustic insulation manufacturer to know
the characteristics of the insulation or the minimum thickness required for the
self-levelling screed

34. Insulation panels laying
● Observe all safety instructions
● Make sure that air temperature is between +5 and +30°C
● Shake the canister vigorously in order to completely mix the content
● Use a dispensing gun and screw the adhesive canister onto it
● To optimize the foam, moisten the substrate with water mist.
● Proceed with the application of the adhesive using the dispensing gun

35. Insulation panels laying
● Apply the adhesive on panel lower surface taking care to make curbs
● Immediately press the panels down firmly
● After hardening, remove any excess foam

36. Distribution manifold

42. PLANNING

43. Planning: Heating load
Design and construction of a radiant system depends on following data:
● Available surface
● Customer needs
● Building and architectural requirements
● Building’s heating / cooling load
Without heating / cooling load information, the systems are sized with a
fixed heating load of 70 W/m2
.

44. Planning: Manifold position
● Manifold position
● Number of manifolds (also depending on
control system)
LR =AF/ T
AF =100 m2
T= 0,1 m
Lr=100/0,1=1000 m
Medium circuits length LC
=75 m
N° circuits 1000/75= 13
N° outlets = 13 + term. + dehum.
Prefer a barycentric position

45. Planning: Manifold position
The manifold position depends on the cabinet size, too

46. Air handling

47. Air handling
In accordance with EN 1264 the cooling flow temperature must not be more than 1 K
lower than the dew temperature calculated for the ambient conditions. (Example room
temperature of 26°C, relative humidity 50%: dew temperature is 14.8°C and flow
temperature cannot be lower than 13.8°C).

27 °C 55% 17,2 °C 16,2 °C
27 °C 60% 18,6 °C 17,6 °C
Low R.H. values allow to obtain higher performances from the radiant system
but require more energy

48. Air handling
The surface temperature must always be higher than the dew temperature.
medium air temperature
difference ∆ΘH
nominal temperature
difference

49. Air handling
● Set the flow temperature to have a surface temperature 2°C higher than
the corresponding dew temperature
● Size the dehumidifier for a dehumidification capacity equal to the latent
design load
● Use a control system that starts the dehumidifier when the design R.H.
threshold value is exceeded
● Use a control system that raises the supply temperature to the radiant
system when the design R.H. threshold value is exceeded.
Take these precautions to prevent surface condensation

50. Dehumidifiers
● Direct expansion systems with hydronic integration
● Air handling with sole circulation
● Neutral or cooled air supply
● Ductable or built-in version
● Management through system climate control

● All connections have the same diameter Ø
125 mm.
The number of ducts must vary according to the air flow rate in order
to maintain the speed below 4 m/s.
Inlet plenum

111. Components
● Designed to to adapt to different
architectural requirements
● pre-cut connections on the bottom and on
the side
● Telescopic extension to adapt the plenum
to different false ceiling heights
Outlet plenum
The grid can be placed:
● directly on the unit’s plenum
● on the unit’s plenum through the
telescopic extension
● on a second plenum a bit far
from the unit through flexible
ducts ø200mm

112. Components
● Half-hard duct in expanded cross-linked PE
● Antibacterial and anti-mould treatment
● Resistant and insulated
● Less pressure drops

117. Mechanical ventilation + heating/cooling
VMC Clima

118. Air systems + ventilation
● Heating & cooling with ducted fan coil units
● Mechanical ventilation with an independent ventilation unit
● Autonomous air distribution ducts with independent regulation
IRIS CN
Altair

119. Advantages
● Fan-coil unit size selected according to heat demand
● Ventilation unit selected according to air exchange need
● Independent calibration
● 2 separate units work and are controlled independently
● Aesthetic: There is only one inlet air terminal in the room

120. Is that possible?
Mixed inlet air terminal Ventilation + Heating/ cooling
HEATING/COOLING inlets Ø 125 mm
with regulation rings
VENTILATION inlets Ø 75 mm
with calibration diaphgram

121. Mixed inlet air terminals
● Plenum in insulated PVC
● Pre-assembled connecting collars
● Wall mounted linear diffusers
● Ceiling mounted linear diffusers
● Double row swivel fins vents
