Surface heating and cooling:
comfortable and economical
The times when energy was wasted carelessly are over. Nowadays the maxim is
“Save energy”. Not only because of the
continuously rising cost for oil and gas,
but also to avoid environmental pollution.
This is why the surface heating and to an
increasing extent the surface cooling are
becoming more and more important when
choosing the heating/cooling system for
new buildings as well as for renovation
projects. Comfort temperatures cannot
only be achieved economically during
heating periods but also during periods
of alternate heating and cooling. Energy
savings result from the fact that the heat in
a surface heating system spreads evenly
and that the flow temperature of the heating and cooling water does not differ that
much from the room temperature (during
heating periods approx. 35°C instead of
70°C and during cooling periods not below
16°C).
Another advantage which, when combined
with a modern heating and cooling generator, e.g. a low temperature or gross calorific boiler, heat pumps or cooled water
from a well, reflects in the energy consumption. A further energy saving is made
as temperatures can be reduced from the
normal 22°C to 20°C without loosing the
“comfort” feeling.
Moreover, surface heating stirs up less
dust than radiator systems and dry floors
prevent the build-up of germs, mites and
fungus which can cause allergies.
Surface heating and cooling system
“Cofloor”:
practical and functional
With the surface heating/cooling system
“Cofloor”, Oventrop offers the specialist
trade not only products of first class quality but also all components required for the
economical installation of various laying
systems.
circuit at the distributor/collector is functioning correctly. This can only be achieved
through hydronic balancing, i.e. the distribution of mass flow according to the heat
demand of the whole system.
Oventrop offers a wide-ranging complete
programme of valves and controls, suitable
for any surface heating system.
This includes base mats, a tacker system (base mat rolls and folded boards), a
clamping rail system, a dry-build system,
edge isolating strips, stainless steel distributors/collectors, components for regulation and hydronic balancing, cabinets,
pipes etc., all complying with standards,
coordinated and in accordance with the latest technical developments.
Regarding the heating pipes, the user may
chose the PE-Xc pipe “Copex”, the composition pipe “Copipe” or the PE-RT pipe
“Copert”. All pipes can be laid fast and easily by only one person.
The composition pipe “Copipe” is also
suitable for supply pipes and for the connection to heating or cooling generators
and distributors/collectors.
As is generally known, a surface heating
system only works perfectly if hydronic
balancing of the mass flow in the supply
pipes and heating circuits was carried out
correctly. A main factor for a trouble-free
operation of surface heating and cooling
systems is to ensure that the central flow
temperature control in front of the distributor/collector and also the automatic individual room temperature control of each

“Cofloor” base mat system
for heating/cooling
1 The Oventrop base mat system “Cofloor”
with its coordinated components allows a
fast laying of the pipes by only one person.
The Oventrop base mats NP-35 and NP-11
are a suitable thermal and sound insulation
made of expanded polystyrene, thermal
conductivity group 040, covered with a
polystyrene foil, building material class B 2,
which is laid directly onto concrete screed
or, if required, onto the additional insulation.
The special grid pattern (50 mm between
the nodules) is suitable for 14 or 16 mm PEXc pipes “Copex”, PE-RT pipes “Copert”
and composition pipes “Copipe”.
The handy base mats have practically no
wastage. They can be laid economically
and easily in any room whether it is small
with many angles or with a large surface
area.
Laying base mats in larger rooms starts in
a corner opposite the entrance door. The
outer rows of the base mats are connected
like a press button closure. At the end of
the room the base mats can be cut to size
as required. Any off cuts can be used in the
same order.
By using the polyethylene foil of the edge
isolating strip and the overlap of the base
mat, the floor surface is completely covered
and ready for the concrete or liquid screed
to be laid.
Therefore a sound bridge to the raw concrete flooring is avoided.
1
Several types of base mats are available
with varying thickness of insulation: NP-35,
NP-11 and the foil base mat NP-R (without
thermal insulation made of polystyrene).
2 The nodules of the polystyrene foil (NP-35
and NP-11) are filled with polystyrene foam.
This increases the firmness of the nodules
for the pipe fixing and secures the heating
or cooling pipes firmly.
Improved sound insulation of the base
mat with a thickness of 35-2 mm:
28 dB

Examples of installation
1 The handy base mats NP-35 (illustr.) and
NP-11 are thermal and sound insulated.
If required, additional insulation has to be
considered, see notes on page 20.
2 The systematic laying begins by placing
the edge isolating strip along the walls.
The edge isolating strip has an additional
bonded foil, allowing a sufficient sealing of
the surface for use with concrete or liquid
screed.
3 The tight fitting of the base mats at the
edges is ensured through a continued
grooved edging. Like a press button closure, the overlap is pressed onto the first
row of nodules of the adjoining mat and
thus closes the area off completely (most
important when using liquid screed).
1
2
4 The strong structure of the nodules and
the clear grid pattern of 50 mm allow a
clean and simple fitting of the pipes by only
one person with the calculated distance of
the pipes being maintained.
5 The coil unwinder allows and easy and
clean laying of the pipes on the mats.
6 In doorways and passages, an expansion
strip separates individual floor areas from
each other. A slit corrugated pipe sleeve
protects the pipes where they cross over.
7 Having submitted the surface heating
pipes to a pressure test, concrete can be
laid.

“Cofloor” tacker system and clamping rail system
for folded board or base mat roll
for heating/cooling
1 The economical Oventrop “Cofloor”
tacker and clamping rail systems for folded
board and base mat roll consist of a folded
board 2 x 1 m or a base mat roll 10 x 1 m
for use with concrete or anhydrite liquid
screed. The folded board and base mat roll
are made of expanded polystyrene and are
laminated with a tissue foil with an imprinted laying screen (screen distance 50 mm).
One longitudinal edge of the folded board
and of the base mat roll has a foil overlap
and the opposite edge is equipped with an
adhesive tape preventing the penetration
of humidity into the underlying insulation
when applying concrete or anhydrite liquid
screed.
The folded board and base mat roll are
classed in the thermal conductivity group
045 and 040 for 30-2 mm, building material class B 2 according to DIN 4102 with a
maximum load of 4 kN/m² and 5 kN/m² for
30-2 mm.
The 14, 16 or 17 mm Oventrop PE-Xc
plastic pipes “Copex”, PE-RT plastic pipes
“Copert” as well as the composition pipes
“Copipe” are fixed onto the folded board
or base mat roll with tacker hooks or selfadhesive clamping rails made of polypropylene.
The folded boards and base mat rolls are
laid directly onto the concrete screed or, if
required, onto the additional insulation.
The Oventrop folded boards or base mat
rolls are laid in the same manner as the
base mats, starting in a corner of the room
opposite the entrance door. Off cuts can be
used in the same order which leaves minimum wastage.
1
The “Cofloor” folded boards, base mat
rolls, tacker hocks or clamping rails allow
an economical, quick and simple laying of
all components.
The imprinted laying screen makes it easy
to lay the pipes either in a spiral or serpentine pattern.
The tissue foil ensures a secure fixing of the
tacker hooks and/or the clean fitting of the
self-adhesive clamping rails.

2,3 Due to the imprinted 50 mm laying
screen on the foil, Oventrop folded boards
or base mat rolls reflect a clean and orderly
picture of the pipework with 14, 16 or 17
mm PE-Xc pipes “Copex”, PE-RT pipes
“Copert” or composition pipes “Copipe”.
The clear lines of the laying screen make it
very easy to tack the pipes in a straight line
with the handy Oventrop tacker machine.

Examples of installation
1 Laying of the “Cofloor” system “folded
board” starts at the edge isolating strip
at the right hand side wall in the relevant
room. The 100 x 200 cm folded board with
the reinforced tissue foil allows a fast laying of the base. If required, an additional
insulation should be considered (see page
20 for further details).
2 If liquid screed is to be used, then the
edge isolating strip must be additionally
sealed (e.g. using a tape gun with selfadhesive tape).
3 One longitudinal edge of the folded board
and of the base mat roll has a foil overlap
and the opposite edge is equipped with
an adhesive tape which is covered with a
plastic strip.

4 Laying the base mat roll (10 x 1 m). Material and process are identical to those
used for the folded boards.
5 By using the Oventrop tacker machine,
laying can be carried out economically
by one single person. The 50 mm laying
screen imprinted on the foil, helps to fit the
pipes in clear and straight lines. The stability and strength of the tacker hooks and
tissue foil ensure that the pipes are fixed
securely.
6,7 The “Cofloor” clamping rail system
(length = 1 m) with a self-adhesive strip for
14 and 16 mm pipes, allows a clean and
fast pipe fixing without damaging the tissue
foil. This also means that it is an additional
advantage when using liquid screed.

“Cofloor” dry-build system for heating/cooling
Accessories
1 Apart from the base mat system and the
tacker system where wet concrete is used,
Oventrop offers the “Cofloor” dry-build system. The components of the dry-build system are suitable for renovating old buildings
as well as for new buildings. The Oventrop
dry-build surface heating/cooling system
can be combined with standard dry flooring
elements (such as Fermacell boards) but
also with normal concrete or liquid screed.
The “Cofloor” dry-build basic element consists of 25 mm thick polystyrene foam.
It serves as thermal insulation and at the
same time as carrier for the individual drybuild heat/cooling conducting strips. The
specific order of the grooves of the basic
element allows the Oventrop 14 x 2 mm
composition pipe “Copipe” to be laid either
in a spiral or serpentine pattern.
Other patterns are also possible.
Oventrop recommends using the composition pipe “Copipe” as it has a lower expansion coefficient than the PE-Xc/PE-RT
plastic pipes. A quiet operation within the
heat/cooling conducting strips is therefore
certain.
The strips made of galvanised sheet steel
with a thickness of 0.4-0.5 mm are the optimum heat/cooling conductor into the dry
flooring elements or the concrete or liquid
screed.
The practical pre-punched breaks points of
the strips (998 mm long) allow an optimum
placement in any room.
Advantages:
-the installation of the Oventrop dry-build
system “Cofloor” is without wastage and
can be carried out by only one person
-overall height is reduced compared to wet
screeds
-optimum heating/cooling output via the
galvanised steel sheet strips and elbows
-no delay in the building progress when
dry flooring elements are installed
-no warm up period is to be observed with
dry flooring elements
-the floor can be walked on immediately
after installation

“Cofloor” dry-build system for heating/cooling
with laminate flooring as layer for load distribution
1 The Oventrop “Cofloor” dry-build system
is not only suitable for use with standard
dry flooring elements (t = 25 mm); it can
also be used in direct conjunction with
heavy duty laminate flooring as autonomous layer for load distribution (for serpentine patterned layout). The requirements
according to DIN 18560-2 “Constructional
requirements” have to be fulfilled.
Due to the lightweight construction of the
system, the dry-build elements have to be
bonded onto the bare floor.
The instructions of the laminate manufacturers must be observed.

“Cofloor” dry-build system for heating/cooling
Wet-build system
The large wall surfaces of a room are ideal
for the installation of a heating or cooling system with composition pipes (e.g.
“Copipe”).
Wall heating or cooling systems are low
temperature systems. The temperature
of the heating medium or coolant is only
slightly above or below the room temperature and most of the energy is radiated.
With the Oventrop “Cofloor” wet-build wall
heating and cooling system, the pipes are
fixed under plaster.
With a wet-build system, the pipes are fixed
directly onto the wall or, if necessary, onto
an additional insulation layer, using selfadhesive, extendable polypropylene clamping rails and suitable wall fixings. This type
of construction is covered with suitable wall
plaster and then with the chosen wall finish, i.e. wall paper, structural plaster, paint,
tiles etc.

A plaster reinforcement may be necessary,
depending on the plastering system used.
It has to be carried out in accordance with
the manufacturer’s instructions. Plaster
re-inforcements are textile inserts made of
plastic or mineral fibres improving the tensile strength of the plaster and preventing
cracks.
Contrary to floor surfaces, wall surfaces
do not represent a direct contact surface,
so the surface temperature can be slightly
higher during heating periods. For reasons
of comfort it is, however, recommended not
to exceed an average surface temperature
of 40°C during heating periods. The maximum temperature load of the wall finish
may reduce this limit. The maximum permissible flow temperatures contained within
the instructions of the plaster manufacturers must be observed.
As with underfloor heating, an incremental
heating test has to be carried out for wall
heating/cooling systems. This will confirm
that it functions correctly but is not intended to dry the wall construction. Procedure
and documentation must be carried out in
accordance with the plaster manufacturer’s
instructions.

“Cofloor” system for wall heating and cooling
Dry-build system
The large wall surfaces of a room are ideal
for the installation of a heating or cooling system with composition pipes (e.g.
“Copipe”).
Wall heating or cooling systems are low
temperature systems. The temperature
of the heating medium or coolant is only
slightly above or below the room temperature and most of the energy is radiated.
With the Oventrop “Cofloor” dry-build wall
heating and cooling system, the pipes with
the conducting strips and elbows are integrated in the thermal insulation. Due to
the large-surface covering of the dry-build
elements, the conducting strips allow a
transmission of the heat into the room via
the wall finish.
The dry-build elements serve as insulation
and carrier for the conducting strips and
elbows. The pre-punched break points of
the strips allow an optimum covering of the
wall surfaces.

Dry-build element
Dry-build board
Wall finish
Provided that no additional insulation is
required, the dry-build elements are fixed
directly onto the wall between wood battens for plaster work. If an additional insulation layer is required, it has to be fixed
firmly onto the bare wall.
The wall is normally covered with dry-build
boards with a thickness of 12.5 cm which
are fixed onto the battens. The dry-build
boards are covered with the required wall
finish (wall paper, structural plaster, paint,
tiles, etc.).
The dry-build wall heating and cooling systems reduces the time of construction.
Due to the dry-build system, no humidity
penetrates the wall.
1
Contrary to floor surfaces, wall surfaces
do not represent a direct contact surface,
so the surface temperature can be slightly
higher during heating periods. For reasons
of comfort it is, however, recommended not
to exceed an average surface temperature
of 40°C during heating periods. The maximum temperature load of the wall finish
may reduce this limit. The maximum permissible flow temperatures contained within
the instructions of the dry-build board
manufacturers must be observed.
As with underfloor heating, an incremental
heating test has to be carried out for wall
heating/cooling systems. This will confirm
that it functions correctly but is not intended to dry the wall construction. Procedure
and documentation must be carried out in
accordance with the dry-build board manufacturer’s instructions.

Dry-build system
1 Installation of the wood battens as support
Fix the first layer of battens horizontally
onto the wall at floor level and the second
approx. 20-25 cm above the bare floor so
that the pipes are not damaged when fixing
the skirting boards e.g. Fix the next batten
layers horizontally with a distance of 50 cm
(corresponds to the width of the dry-build
elements). Fix the dry-build elements onto
the wall using a suitable adhesive. Finally
push in the conducting strips and elbows.
2 Feed composition pipe “Copipe” from the
supply of the distributor to the wall heating/
cooling system. Starting from the bottom,
press the pipe into the strips in a horizontal
serpentine pattern.
(Laying distance depending on the model is
12.5 or 25 cm.)

As for the distributor/collector, item no.
140 43, the calculated flow rate is set at the
handwheel of the flow measuring and
regulating device. The set value can be
read off the viewing glass with scale
(0-5 l/min.). Each heating/cooling circuit
can be isolated without modification of the
set flow rate which means that the set flow
rate is re-stored after reopening an isolated
heating/cooling circuit. The functions “setting” and “isolation” are thus autonomous.

stem of the regulating insert. A reproducible
presetting is possible.
Oventrop offers a calculation programme
for the design of a surface heating system
with composition pipe “Copipe”. The valve
inserts M 30 x 1.5 in the return collector which are convertible to thermostatic

stem of the regulating insert. A reproducible
presetting is possible.
Oventrop offers a calculation programme
for the design of a surface heating system
with composition pipe “Copipe”.
The valve inserts M 30 x 1.5 in the return
collector which are convertible to thermostatic operation allow the individual room
temperature control prescribed in the
Energy Saving Directive. The Oventrop
electrothermal actuators and room thermostats or thermostats with remote control
which are available as accessories, are
used for this purpose.

Hydronic balancing of the heating circuits
Regulation with flow measuring and regulating device
As with any heating system, a hydronic
balance according to DIN 18380 is also
required for the surface heating system.
Regulation of the surface heating circuit is
carried out at:
Stainless steel distributor/collector
“Multidis SF”, item no. 140 43 52 to
140 43 62,
via the flow measuring and regulating devices at the flow distributor.
Setting is carried out whilst the circulation
pump is in operation.

All valves of the heating circuit are to be
fully open.
1Lift the locking ring until it clicks into
position.
2Wind up locking cap.
3Set the calculated flow rate by turning the
red handwheel of the first flow measuring
and regulating device.
The set value can be read off at the red
indicator ring inside the viewing glass.
The scale shows values between 0 and
5 l/min. Carry out setting of all heating
circuits.
The first values are checked and
readjusted if required.
4With the setting being completed, close
locking cap until stop. Protect setting of
the flow measuring and regulating de vices by pushing the locking ring down
until it clicks into position.
Isolation and opening
Each heating circuit can be isolated without modification of the set flow rate which
means that the set flow rate is restored
after reopening an isolated heating/cooling
circuit. The functions “setting” and “isolation” are thus autonomous.
1 Isolation:
The heating circuit is closed by turning the
red handwheel clockwise until stop.
2 Opening:
Turn the red handwheel anticlockwise until
stop. The flow measuring and regulating
device is opened and the set flow rate is
restored.

Brass distributor/collector “Multidis SFI“ for
industrial surface heating and cooling systems
Surface heating and cooling systems for
commercial and industrial buildings are
becoming more and more important. The
ceiling heights of these buildings are usually very high and therefore an even and
economical distribution of the required temperature is needed. Utilising the large surface area together with a favourable vertical
temperature profile fulfils this demand.
The integration of the surface heating
system within the ground floor allows an
interior design that is free and flexible.
Conventional visible heating systems have
to be cleaned and serviced regularly, but
industrial surface heating systems do no
require individual maintenance. Surface
heating in commercial and industrial buildings is therefore a heat distribution system
which is economical and energy efficient
and with technical effort it can also be used
for cooling.
1 The brass distributors/collectors “Multidis SFI” allow a central distribution of the
heating or cooling water to the different
circuits of an industrial surface heating/
cooling system. It is recommended to equip
the distributors/collectors with ball valves
DN 50. They allow the isolation of the supply and return pipe, e.g. for maintenance
work. Consoles with pipe clamps (including
sound insulation supports) allow a fixing of
the distributor/collector onto the wall.
The ball valve at the flow distributor and the
regulating valve at the return collector allow
the isolation of each heating circuit.

2 Summary with system components
Five different distributor modules with two
to six heating circuit connections allow an
individual combination of up to 20 circuits.
The individual modules are interconnected
with flat seals. The distributor/collector
ends are closed with plugs.
3 PE-Xc plastic pipes “Copex” sized 20 x 2mm
and 26 x 3 mm can be connected to the
heating circuit connections of the brass
distributor/collector “Multidis SFI” with corresponding compression fittings. The pipes
are made of cross-linked polyethylene and
are oxygen tight according to DIN 4726.

The sheltered oxygen barrier protects the
PE-Xc plastic pipes “Copex” against damages on site.
4 Hydronic balancing of the individual surface heating circuits has to be carried out in
accordance with the VOB DIN 18380 standard. Regulation is carried out at the regulating valves integrated in the return collector of the “Multidis SFI”.

Flow temperature control of surface heating systems
Control unit “Regufloor H” and
boiler connection system “Regumat F-130”
Economy and comfort of a surface heating
system can only be achieved if the correctly
calculated pipe layout and floor construction
is adhered to. Moreover, a temperature and
flow control of the heating medium adapted
to the surface heating must be taken into
consideration.
The main points of the regulation are the
provision of a permissible flow temperature
of the heating medium (this should be
separate from the boiler regulation) and the
distribution of mass flow in the individual
heating circuits of the stainless steel distributor/collector.
1 Control unit “Regufloor H”
Fixed value control unit for the connection
to the stainless steel distributors/collectors
“Multidis SF” for surface heating which also
supply a radiator circuit. The unit regulates
the flow temperature of the heating medium
to a constant value (fixed value control) by
adding some of the return flow water of the
collector with a temperature controller with
contact sensor and a three-way valve.

The medium in the heating circuits of the
surface heating system is circulated by an
electronically controlled pump. To protect
the surface heating against overheating, for
instance in case of failure of the temperature
controller, the control unit is equipped with a
module which switches the pump off.
1
2 The advantage of the control unit
“Regufloor H” is the facility to integrate
the flow tem-perature control of a surface
heating into the heating circuit of a radiator
system. The illustration displays the
connection to the supply and return of the
radiator system.
3 Flow temperature control can be carried
out directly at the heating generator by using
the Oventrop boiler connection system
“Regumat F-130”. Flow temperature control
is carried out by a temperature controller
with immersion sensor and a three-way
valve.
By using this solution, the whole circuit of
a heating system can be operated with the
flow temperature adapted to the surface
heating.

Weather guided flow temperature control
of surface heating systems
Control unit “Regufloor HW”
1 The “Regufloor HW” unit is used in
surface heating systems to control the
flow. Regulation of the flow temperature
is weather guided, i.e. it depends on the
outside temperature up to an adjustable
maximum. This way, the maximum permissible flow temperature (e.g. 45°C) for the
surface heating can be maintained.
The heating circuit controller “Regtronic
RH-B“ of the “Regufloor HW“ controls the
position of the three-way diverting valve
via an electromotive actuator and thus the
flow temperature. This is dependent on
the temperature measured by the outdoor
sensor and the set heating curve of the
heating circuit controller. The pump control
is also weather guided, i.e. it is switched on
during heat demand and operation of frost
protection.
Individual time profiles for switching from
day- to night time operation can be programmed for each day (Mo-Su).
Some installations may call for the control
of further functions. The heating circuit
controller “Regtronic RH-B” offers a free
choice of additional functions (e.g. potable
hot water preparation, re-loading, solid fuel
boiler, circulation, thermal disinfection etc.).

Flow temperature control of surface heating systems
Control unit “Regufloor HX“ with system separation
Years of experience have shown that unfavourable conditions in surface heating
systems with plastic pipes may lead to corrosion problems caused by a penetration of
oxygen.
In pure radiator systems, such corrosion
problems normally do not entail problems
as they may deposit in a number of stabilization zones.
In surface and especially underfloor heating
systems, such deposits could impair the
flow behaviour in the underfloor circuit. Malfunctions or even a breakdown of the circuit
could be a result.
1 The heat exchanger of the control unit
“Regufloor HX” divides the system into a
primary and secondary circuit. The primary
circuit is the heating system and the secondary circuit is the surface heating circuit.
This way, surface heating circuits with pipes
without oxygen barrier can be connected.
These can be found in old installations or,
system related, in new installations. Due to
the separation, a penetration of oxygen from
the surface heating circuit into the boiler
circuit is avoided. The other way round, a
penetration of possible corrosion products
from the boiler circuit into the surface heating circuit and thus a silting-up of the pipes
is also avoided.
1
The regulating valve on the primary side
serves to control the set flow temperature.
The temperature is detected with the help of
an immersion sensor on the secondary side.
The Grundfos pump “ALPHA” electronically
controls the pump output according to the
current heating water demand. Due to its
bronze body, the pump is corrosion resistant.

“Cofloor” system extension for surface cooling
Control unit “Regufloor HC” for
alternate operation of heating and cooling
for all laying systems
The systems “Base mat”, “Tacker”, “Drybuild” and “Clamping rail” are also suitable to generate a comfortable room
temperature on warmer days of the year,
when cooling water rather than heating
water is fed through the pipework. The
term “thermal comfort” for room cooling
is explained further in DIN 1946 part 2. It
is also described as soft or quiet cooling.
This cooling system is not accompanied by
draughts, high air movements, dust generation or high noise levels typical of the
classic air cooling methods. In addition, the
energy exchange between humans and a
cooling surface is through radiation, which
is similar to the thermal balance of human
beings.
1 If the system is operated alternately with
heating or cooling water, then the permitted flow temperature must be checked
for the surface heating as well as for the
surface cooling operation. Oventrop offers
the control unit “Regufloor HC” for this
purpose, which will keep the temperature
of the medium at a constant set value even
during cooling operation by mixing some
return flow water. The three-way valve is
operated here by an electromotive actuator 24 V (0-10 V) which receives its signals
for heating and cooling from an electronic
room thermostat.
2 The flow temperature regulating set for
outside temperature guided heating and
cooling via the corresponding surface heating and cooling systems enables an automatic changeover from heating to cooling
for each application.

and timed function via two PI controllers
and preset parameters for an easy initial
operation. The remote control can be used
for certain applications (remote control of
the operating mode, correction of the nominal values and setting of the clock).

calculates the dew point of the air humidity.
In connection with the controller heating/
cooling, it avoids condensation of the pipework and chilled surfaces.

1 The changeover from heating to cooling is
carried out via the controller heating/cooling. It is, amongst others, connected to the
outdoor sensor, the flow temperature sensor as well as the room humidity measuring
transducer. The required room temperature
is calculated with the help of the measured
values of these system components and is
controlled via the electromotive actuator.
The controller heating/cooling also transmits the operating mode “changeover from
heating or cooling” to the electrothermal
actuator for the integration of the heating or
cooling generator.
Heating cicuit regulation of surface heating systems
Actuators and room thermostats
Wireless controls
The Energy Saving Directive calls for a central flow temperature control of the heating
medium (e.g. via the control unit “Regufloor”) and for an individual selfacting room
temperature control e.g. with room thermostats and actuators.
Such regulating systems even out any temperature differences (e.g. short opening of
a window).
The Oventrop room thermostats and actuators fulfil these requirements. Wired and
wireless devices are available for this purpose. The wired items are regulating components which work as two point (opened/
closed) or proportional (0-10 V) actuators.

the cabinet (see illustr. 3) are connected to
the receiver. Apart from being suitable for
new buildings, existing buildings can also
be upgraded with the wireless temperature
control.
It is also possible to switch from heating to
cooling operation.
5,6 For a wired individual room temperature control, Oventrop offers proportional
actuators (0-10 V) which work with a 24 V
supply voltage. The nominal value range of
the electronic room thermostat can be limited by use of the hidden limiting elements.
The proportional actuator has the facility to
reverse the actuation. This feature is
necessary for surface cooling.

Double regulating and commissioning valves for hydronic balancing
Heat meter connection set
If the room temperature in partial areas of
the heating system is reduced, it must be
ensured that the other areas are not underor oversupplied. This condition is governed
by the pressure drops in the pipe system
and the installed valves and can only be
determined by a heat demand and pipework calculation. Oventrop offers relevant
calculation programmes which amongst
other, will deliver the settings of the valves
for hydronic balancing not only for the
regulation of mass flow to the stainless
steel distributors/collectors but also of the
individual heating circuits connected to the
stainless steel distributors/collectors.

Differential pressure regulators for hydronic balancing
Heat meter connection set
In addition to the manual hydronic balancing of the distributors/collectors by using
the double regulating and commissioning valves, a hydronic balance during low
demand periods can also be achieved
with the help of the automatic differential
pressure regulators “Hycocon DTZ”. This
ensures that the valves of the individual
heating circuits are protected from unacceptably high differential pressure.
Illustration:

heating combination of a low

“Hycocon DTZ”
1 Example of a two pipe heating system
with radiators and surface heating areas
connected to the risers. A differential pressure regulator “Hycocon DTZ” is installed
in front of every surface heating area. The
regulator has to be set to a nominal value
to be determined (e.g. 150 mbar). The regulator will maintain a constant differential
pressure between supply and return within
a necessary proportional band.
2 The installation of an automatic differential pressure regulator “Hycocon DTZ”
allows that the distributor units can operate
independently. The permissible differential
pressure between supply and return can be
set and locked at the “Hycocon DTZ”.
A change in the system pressure has therefore no influence on the heating circuits of
the distributor units of the surface heating.
A manual balance is not required.

The “Unibox TSH” / “Unibox T” /
“Unibox E T” / “Unibox E TC” allows the
control of the room temperature via the surface heating system. It is used in combination with a low temperature heating system
with a maximum flow temperature of 55°C.
The “Unibox RTL” / “Unibox E RTL”
allows the temperature limitation of heating
surfaces with return temperature limiter.
The room temperature is still controlled via
the radiator. Installation is carried out in
combination with a radiator heating with a
maximum flow temperature of 70°C.
The “Unibox plus” / “Unibox E plus” /
“Unibox vario” / “Unibox E vario” allows
the individual room temperature control
with thermostatic valve and the temperature limitation of heating surfaces with
return temperature limiter.
As for the “Unibox RTL”, installation is
carried out in combination with a radiator
heating with a maximum flow temperature
of 70°C.
Wrong
Installation and assembly:
For a simple installation of the pipes in the
wall, Oventrop offers a pipe conduit unit
sized to the depth of the “Unibox”/
“Unibox E”.
Installation may be carried out easily.
The pipe conduit unit and the installation
set are fixed in the wall (see illustr. 1 installation sketch). The heating pipes are laid
according to the installation instructions.

Important:
The “Unibox” always has to be installed
behind the surface heating circuit, i.e.
in the return pipe. The direction of flow
has to be observed (illustr. 2).
Return
Supply
Application:
The different models of the “Unibox” are
suitable for the operation of a surface heating system in rooms with a heating surface
up to 20 m². They are designed for the connection of one heating circuit. When using
pipes with an inner diameter of 12 mm, a
length of 100 m must not be exceeded.
It is to be observed that the supply and
return pipe are laid alternately side by side
(see e.g. the spiral laying in the installation
sketches pages 2, 3 and 4). A constant
heating of the floor is thus guaranteed.
Surface heating

For the connection to the valve, Oventrop
offers suitable compression fittings. The
pipe conduit unit is closed and plastered.
The fixing channel is closed with the cover
plate. Control is carried out via the thermostat which is easily accessible. Care should
be taken that the thermostat is not influenced by other heat sources.

- Do not install near other heat sources,
e.g. additional radiators (illustr. 3).
- Protect thermostat from direct sunlight
(illustr. 4).
- Do not install at a location exposed to

Example of installation for two surface
heating circuits:
In case of heating surfaces exceeding 20 m²
and a pipe length of more than 100 m
per heating circuit, it is recommended to
connect two heating circuits of the same
size to the “Unibox” (illustr. 5). The installation is then carried out by use of the Oventrop “h” fitting, item no. 102 87 50 and the
fitting item no. 101 63 04 or the Duo connection piece.

Section of the system:__________________________________________________________________________________
Requirements
Before laying the screed, plaster or levelling compound, tightness of the heating/cooling circuits of the surface heating/cooling system is tested by carrying out a water pressure test. Contrary to the VOB C (DIN 18 380 standard), the test pressure
must be at least for 4 bar and not more than 6 bar. This pressure must be maintained throughout the laying of the screed/
plaster*.
The test pressure is carried out section by section after having flushed the individual heating circuits. It must be ensured
that the succeeding sections of the system are protected from excess pressure (if necessary, by main isolation device in
front of the distributor/collector).
Alternatively, the tightness can also be tested by carrying out a pressure test with compressed air. Here, the maximum test
pressure amounts to 3 bar.

Requirements
An incremental heating process must be carried out in order to check the function of the heated floor construction. It serves the installer as documented evidence for the realization of a flawless installation. When using concrete screed, the
construction work should only be continued 21 days after having laid the screed and 7 days after having laid calcium sulphate screed (or according to the manufacturer’s indications).
According to EN 1264-4 a flow temperature between 20°C and 25°C must be maintained for at least 3 days. After that,
the maximum design temperature has to be maintained for at least 4 days. Manufacturer indications (e.g. for liquid screed)
deviating from the standard or this record must be observed and be recorded.

Attention
Depending on the heating capacity of the heat generator, the incremental heating process may possibly have to be carried out
section by section. In this case, all heating circuits of one screed field have to be heated at the same time.
The incremental heating process does not guarantee that the screed is dry enough to start flooring work.

Requirements
An incremental heating process must be carried out in order to check the function of the heated or cooled floor, wall or
ceiling construction.
Incremental heating of dry-build systems is only started after all filling and adhesive bonding work has been completed.
The filler and bonding agent have to be cured. The instructions of the manufacturers must be observed.
The maximum design flow temperature (in general up to 45°C) has to be maintained for one day.
Where there is a risk of frost, the system has to remain in operation. Manufacturer indications deviating from the standard
or this record must be observed and be recorded.

same time.
When switching off the underfloor heating after the heating up period, the screed has to be protected from draught
and a quick cooling down until it has cooled down completely.

Requirements
An incremental heating process must be carried out in order to check the function of the heated construction. Before
starting the incremental heating process, the waiting period according to the indications of the levelling compound/screed
manufacturer must be observed (at least 2 days). In general, a flow temperature of 25°C has to be maintained for 1 day.
After that, the maximum design temperature (in general up to 45°C) has to be maintained for at least 1 day. Where there
is a risk of frost, the system has to remain in operation. Indications of the levelling compound/screed manufacturer (e.g.
waiting periods, temperatures) deviating from the standard or this record must be observed and be recorded.

Attention
The incremental heating process does not guarantee that the levelling compound/screed is dry enough to start flooring work.
This has to be decided by the flooring company. When switching off the underfloor heating after the heating up period, the
heating surface has to be protected from draught and a quick cooling down until is has cooled down completely.

Oventrop electrothermal actuators are used for
heating, ventilation and air-conditioning. The
actuators serve to control the room
temperature and can be used e. g. with
conventional radiators, radiators with
integrated distributor, distributors for surface
heating, radiant ceiling panels, chilled ceiling
systems and induction air systems in
combination with two point room thermostats.
Further applications in bivalent heating
installations.
For zone and room temperature control.
Connecting cable 1 m.
With First-Open function (except for actuators
"opened with current off") and stroke index.
Simple plug-in connection with valve adapter.
Actuators can be installed in any position.
As for the model with auxiliary switch, a pump
can e. g. be switched via the integrated volt
free contact. Due to their construction, the
electrothermal actuators are secured against
overvoltage which could occur when switching
on neon tubes. A varistor is thus not necessary.
Is required in combination with room
thermostats to protect chilled ceilings against
condensation.
An actuator interrupting the cooling water flow
is for instance activated in conjunction with the
"Regufloor HC".

Application:
The regulating set with "Tri-D TR" three-way
diverting valve is required for the control of the
flow temperature of a surface heating system,
for instance in combined radiator/surface
2013
heating systems. The required flow rate is set
at the temperature controller. The electric pipe
contact safety switch switches the pump off as
soon as the set flow temperature is exceeded.
Depending on the setting of the temperature
controller, the three-way diverting valve divides
the flow volume into a return flow and a bypass
flow. The check valve installed in the bypass
prevents a wrong flow against the three-way
diverting valve.

1 The almost ideal “temperature profile”
from floor to ceiling.
Compared to other heating systems, the
surface heating can be referred to as the
heating system with the ideal temperature
profile. Depending on its usage, the hot
water surface heating system offers the
advantage that an energy saving of 6 to
12% may be achieved due to the lower
temperature of the heating medium and the
lower room temperature.
2 As system supplier of the surface heating
and cooling system “Cofloor”, Oventrop
offers high quality system solution guaranteeing maximum benefit for the installation
and the later comfort. This does, at the
same time, mean an obligation to observe a
multitude of rules and standards.
3, 4 Working supports
Oventrop supports its partners regarding
planning, calculation, completion and
regulation. Current information material
like catalogues, technical data sheets and
