- Introduction
SpeedUp™ and
SpeedUp Eco™
Heating systems
Dry installation and fast reacting wet screed
underfloor heating with low construction height
and weight, and quick response time.
Wherever a low construction floor is required to
save on headroom, or a screed floor is unsuitable,
the SpeedUp™ dry installation is a suitable
alternative. It also suitable for wet screed where
the floor level in heated rooms must stay the
same as in any adjoining unheated room.
SpeedUp™ solves individual heating problems.
The SpeedUp™ underfloor heating systems are
universal and optimum for all new and old
buildings. They are particularly suitable for
retrofitting in restoration work, extensions, and
for use in dry and timber installations.
The individual heat panels are only 30 mm thick
and are prefabricated. In contrast to steel
(thermal conductivity 45 W/mK) the aluminium
covering all heat panels is a very good conductor
of heat (thermal conductivity 200 W/mK) so that
the heat is distributed equally and fast over the
entire area.
The pipes are 100% impervious to air so that over
the mid and long term the metal parts of the
heating system cannot suffer from corrosion.
Heat exchangers are not required.
Dry screed (20-25 mm) as well as engineered
flooring and laminates are suitable for load
bearing. Wherever floor height is a problem,
Danfoss Strongboard (5 mm) load bearing panels
offer the opportunity to lay tiles straight onto
SpeedUp™. In contrast to traditional underfloor
heating systems, a very thin layer of liquid screed
can be applied to SpeedUp™, saving mass, weight
and height.
The system is able to react very quickly to
temperature changes and is adjustable like light.
The whole system is available from one source.
Heat output is achieved quickly.
The extremely low flow temperatures are energy
efficient which makes the system ideally suited
for condensing boilers, heat pumps and solar
energy.
Via accessories (mixing shunts, RTB valves) the
system can be connected to existing heating
systems.

System parts
For planning and construction legal requirements
and regulations have to be followed.
For dry underfloor heating EN 1264 is applicable.
Three Danfoss basic constructions are possible
under EN 13813 'Screed in the Building Industry'.

Thermal
resistance (R)
(m K/W)
* When ground water table is ≤ 5 m this value should be raised !
The Danfoss SpeedUp™ system parts are made of
compression resistant polystyrene EPS DEO 240
kPa or of wood fibre 140 kPa. The wood fibre load
bearing panels serve as thermal and sound
insulation.
To achieve optimum lateral heat transfer (edge/
outside wall much heat - inner area less heat) the
heat panels have pre-formed pipe channels with
two distances. The edge zone can be covered by
EZ-Panels with pipe distances of 12.5 cm and in
the comfort zone CZ-Panels with pipe distances
of 25cm are installed. Both systems are pre-channelled and are covered with heat conducting
aluminium sheet for optimum heat distribution.
The aluminium pipe channels are omega shaped
so that the pipes easily snap in when installed but
cannot ‘spring’ out afterwards. The channels are
beaded at the ends to avoid damage to the
composite pipe during and after installation.
The 1 m long and 0.5 m wide system panels are
pre-scored with the heating plates already cut in
the appropriate places so that the panels can be
snapped over the knee without tools, thus
avoiding unnecessary breaks (this does not apply
to SpeedUp Eco™ panels).

This way the system can be adapted to any room
dimensions, even the most awkward corners can
be fully covered.
Together with the two different panel types there
are matching 25 cm header panels, EZ and CZ, to
allow the pipe to return. The header panel CO
allows the cross over between 12.5 cm and 25 cm
pipe distances. Panels for flow and return pipes
CZ and EZ without aluminium plates make it
possible to take supply and returns through
unheated rooms and rooms with low temperature requirement without losing heat. Remaining
areas or areas in front of manifold require blank
panels BP. These are pre-scored as well.
Speedup Eco™ makes up the system with
additional 12.5 cm wide and 1 m long flow and
return panels with routed pipe channels and 90°
curve panels (to allow change of direction in the
flow and return area).
Support battens for stabilisation and sound
insulation as well as load bearing steel sheets
(stabilisation in front of manifold) and heating
aluminium plates (for header panels) complete
the system.

Substrate requirements
Tolerance levels

Levelling of substrate
(Danfoss recommends)
The following reqirements have to be met when
installing Danfoss SpeedUp™ heating systems:
The substrate must be dry and firm, it must be
Group Reference 0.1 m 1 m 4 m 10 m 15 m
Finished floors but subject to more stringent

requirements. e.g. self-levelling fillers
The system panels must lie fully flat on the
surface since load bearing steel plates in dry
installations cannot compensate for unevenness.
If the prerequisites are not met, levelling and
adjustments have to be undertaken dependent
on the deviation and surface (see table).

Greater installation height with unevenness or
many pipe channels may require levelling and
build up of extra height with screed on insulation. The screed will achieve the necessary
evenness and will make further measures
unneccessary. It is also possible to add further
height using commercial insulation material.

10-50 mm for
small objects with

Cover service
channels over 3
cm and construction over 11 cm
with screed on

Unevenness of up to 3 mm is not a problem. Thin
wood fibre insulation or moisture barriers (e.g.
Gefitas/Firma Gefinex) eliminate this problem.
Unevenness of up to 10 mm can be eliminated
with self-leveling compound. Greater height
differences can be overcome with bonded dry
levelling compound (e.g. Danfoss dry levelling
compound). Before installing the compound on
the suspended floor the prepared area should be
lined to protect against any compound falling
through. As a rule the thickness of the levelling
compound is between a minimum of 10 mm and
a maximum of 60 mm. It is advisable to read the
manufacturer information. A finishing board is
used to make the compound safe to walk on. The
use of additional insulation with Danfoss dry
levelling compound makes the installation of the
board unnecessary. The additional insulation can
be installed directly on the leveling compound. It
is always advisable to follow the manufacturer
information when installing dry screed panels If
there is residual moisture in the building, a 0.2
mm PE foil will prevent the rising of the moisture
VGCTA302 © Danfoss 09/2009
into the building. Length of foil overlap by 20 cm,
at the edge up to floor level. Floors between
storeys don’t need a moisture seal since there is
no residual moisture. Suspended floors should
not have any lining since moisture could be
trapped and cause lasting damage. In accordance
with EN 13967 constructions on ground floors
must be protected against any moisture entering
the floor. In the absence of a lining, bitumen or
synthetic lining can be used; the floor will need
levelling afterwards. Such measures may have to
be decided by the builder.
For floors with greater exposure to humidity e.g.
bathrooms or entrance halls, dry screed panels
such as Fermacell will need a thick coating or a
sealing system before tiling. For shower rooms
and washrooms with floor drains in public and
commercial premises, Fermacell screed panels
are not suitable.
For wet areas, Fermacell Powerpanel SE can serve
as an alternative.

- Floor Construction
Separation of pipe from
load bearing layer
Low surface weight
Level free surface
SpeedUp™ is the Danfoss underfloor heating
system, where pipes are integrated into the
system panels and decoupled from the load
bearing layer.
The relatively light weight of dry screed makes
the whole construction light weight, which is an
advantage as well as essential in restoration of
older buildings, where floors are of lower load
bearing construction.
Danfoss Strongboards provide a unique solution
for level free floors.
With a thickness of only 5 mm the Strongboard
for Tiles and Laminates provides sufficient
stability as a load bearing layer to comply with
the demands of EN 1991 (Actions of structures).
The Strongboard for Carpet and Synthetics
provides the same stability, but with a thickness
of 10 mm.
Danfoss Strongboards are made of recycled
materials mixed with shreds of aluminium, which
ensure good heat transfer through the Strongboard to floor finish.
This means that the joints of the load bearing
panels do not have to be taken into consideration
when planning the heating circuit.
Where Strongboard for Tiles and Laminates does
not have a completely smooth surface, the
Strongboard for Carpet and Synthetics can serve
as a smooth surface for floor finishes like carpet,
linoleum, vinyl etc. A smooth surface can
therefore be achieved with only 10 mm instead of
the 20 mm or more that dry or wet screed
requires.
Danfoss Strongboards can be used as a replacement for the Fermacell 20 mm or 25 mm panels.
Basic construction
Danfoss Strongboards gives you the possibility to have almost level free floor surfaces
- no matter which floor finish you choose.
