In the GasSolarUnit a gas condensing
boiler is integrated in a hot water
storage tank.
The domestic hot water storage tank is
filled with storage water which is not
pressurised. The storage water is
heated by the condensing boiler via a
stainless steel corrugated pipe heat
exchanger. Alternatively, the storage
tank can also be heated using solar
energy.
For heating the domestic hot water
there is a stainless steel corrugated
pipe heat exchanger over the full depth
of the water on the inside of the
storage tank. The large heat
exchanger surface area means that
correspondingly large volumes of
domestic hot water can be heated in
a short time period.
The storage tank is therefore always
operating as a stratified storage tank.
This increases the storage tank
potential considerably and ensures
optimum use, particularly when using
solar energy utilisation.
Even without the use of solar energy
utilisation, the stratified storage
concept permits the preparation of
even larger volumes of hot water.
The integrated condensing boiler has a
fully-electronic digital control system.
This provides weather-dependent
control of the feed temperature.
It controls the storage tank
temperature and contains individuallyadjustable time programs for the
heating and for hot water preparation.

In the midst, not just a
spectator
The compact layout means that the
required floor area and installation
costs are kept to a minimum.
A floor area of just 59 x 61 cm
(0.36 m2) or 79 x 79 cm (0.62 m2) can
accommodate the complete gas
condensing boiler with hot water
storage tank and solar storage tank.
Since the unit does not need to be
wall-mounted, and is entirely mounted
flat on the floor, installation is child's
play. Noise transmission from the unit
to the building is therefore effectively
prevented.
Innovative down to the last detail.
The heart:
The gas condensing boiler
The aluminium boiler body of the gas
condensing boiler is a true innovation.
It is flat and round and has a centrally
arranged combustion chamber. The
flue gas is directed
in a spiral around
the burner chamber
and then drawn
away upwards.
The condensate
produced by
cooling the flue
gases is collected in the boiler body
and is drained from the tank via a
plastic tube.
The gas burner: variable,
quiet and efficient
The high-efficiency surface burner
fitted ensures optimum and toxic-free
combustion. This burner operates in a
fully modulating mode i.e. it matches
its output directly to the demand.
The output ranges:
■ 4 to 20 kW in the GSU 320
■ 4 to 20 kW in the GSU 520S
■ 6.5 to 30 kW in the GSU 530S
■ 8 to 35 kW in the GSU 535
The burner operates extremely quietly.

It thinks for you The electronic control
system
2. Theta 23R
The control management of the ROTEX
GasSolarUnit is performed by a fullyelectronic digital control system. There
are two different versions:
- Alpha+ 23R
- Theta 23R
1. Alpha+ 23R
The digital control system Alpha+ 23R
has a clear four digit display which is
integrated in the upper section of the
ROTEX GasSolarUnit.
All the fundamental functions are
selected using two rotary switches.
The values can be adjusted simply
using push-buttons.
The Alpha+ 23R has three time
programs for the control of the heating
circuit and the hot water preparation.
The time controls are preprogrammed;
one of these can be adapted to the
individual wishes of the user. In
addition, the Alpha+ control system is
prepared for controlling an additional
mixed circuit.
The heating water temperature is
automatically adjusted according to
outside temperature. The control
system itself senses winter and
summer and switches the heating
system on or off as required.
The fully-electronic digital control
system Theta 23R meets the highest of
demands. The display shows values
and parameters in clear text. The main
operating element is a rotary switch
with which the operating modes, time
programs and operating parameters
can be set and quickly and simply
altered.
Fundamental system parameters can
be viewed and adapted by the heating
engineer.
The heating water temperature is
automatically adjusted according to
outside temperature. The control
system itself senses winter and
summer and switches on or off the
heating system as required.
The Theta 23R has individually
adaptable time programs for simple
control of the heating circuit and hot
water preparation. It can also be used
to control an additional mixed heating
circuit. This requires that only the
mixer, pump and sensor are plugged
into the control housing. It is also
possible to connect an additional
circulation pump.
The Theta 23R control system can be
extended by room controllers and
thermostats which conveniently
control and monitor the heating
system.
[5]
Air in – flue gas out
The heat stays inside
The GasSolarUnit is operated in room
air independent mode as standard.
The burner draws the necessary
combustion air directly from the
outside through an installation shaft or
a double-walled flue gas duct.
The storage tank is a twin layer
structure made entirely from plastic.
The space between the internal and
external tank is filled with expanded
foam and is extremely heat insulating.
This high level of insulation ensures
low overall heat losses for the ROTEX
GasSolarUnit.
Advantages of room air independent
mode:
■ The boiler room does not need a
ventilation opening to the outside
and thus does not get cold
■ Lower energy consumption.
■ Dust, solvents, detergents etc. are
not drawn in by the burner. This
means that the room can also be
used as a laundry, workshop or
similar application
■ Also possible in roof space siting
■ Additional energy savings due to
the flue pipe preheating the
combustion air
Hot water, as much as you
want – as often as you want
The domestic hot water is contained in
a stainless steel corrugated pipe which
extends in a spiral from bottom to top
of the storage tank
which is filled with
unpressurised water. The
fresh water which is
drawn in is heated in the
flow principle.
This type of water
direction creates stable,
clearly defined
temperature stratification.
Corrosion resistance, low
tendency to calcification
and, above all, optimum
water hygiene characterise this type of
heating. The large storage tank
capacity ensures that the SolarUnit
always provides sufficient hot water.
This provides the highest levels of
water comfort. And when you heat the
GasSolarUnit with solar energy, hot
water is available practically cost-free
throughout the summer – you can then
"enjoy saving energy".
Water hygiene is our
principle
The structure of the ROTEX GasSolarUnit ensures that it has optimum
inherent water-hygienic properties
since the water to be heated is
directed and heated through a piped
system.
The water volume in the domestic
hot water heat exchanger is just
19/24 litres, and thus amounts to only
a fraction of the volume of water in
normal storage tanks.
Low flow sections or sections that are
not heated properly on
the hot water side are
completely eliminated
using the ROTEX GasSolarUnit. The domestic
hot water is entirely
contained in a piping
system so that the
deposits such as
sediment, rust or other
deposits which can arise
in large volume tanks are
not produced. Water that
is charged first is also the
first to be removed (first in first out
principle).
The outstanding hygienic advantages
of this type of hot water storage tank
have been confirmed
in extensive tests
performed at the
Institute of Hygiene
at the University of
Tübingen.
Keyword: Legionella
[6]
Legionella bacteria
There are about 35 types of
Legionella. At least 17 of these
produce illness.
The main consequences are:
Pontiac fever: flu-like symptoms
which subside after a few days.
Legionnaire's disease: severe
bacterial lung infection.
In 15 to 20 percent of the cases the
infection leads to death.
Systematic heating.
Systematic condensing
technology
Comparison with
conventional heating
technology
Modern condensing technology
converts the fuel used into usable heat
virtually without loss.
This is both good for the environment
and your wallet, since lower energy
consumption means lower heating
costs, less use of energy resources and
a reduction in CO2 emissions. During
this process, flue gases are cooled to
the extent that the steam they contain
is condensed. The energy created is
used as heat for heating.
Existing older heating systems use a
lot of primary energy as a result of
their low levels of efficiency.
Low temperature boilers, which are
still being installed, waste valuable
energy.
The resulting CO2 emissions and
energy costs are correspondingly high.
Just by using a condensing boiler you
can save a considerable amount of
energy.
Extensive use of solar energy for
heating and hot water production
provides an additional renewable
contribution.
If the remaining fuel is, for example,
20 % biogenic then the consumption
of primary energy is reduced by
approx. 64 % to just 36 % compared
to a conventional existing system.
The CO2 emission is reduced in the
same ratio.
In this example, from over 8 t
CO2/year, more than 5 t CO2/year are
saved.

Integrated solar energy utilisation
for heating and hot water.
As much sun as possible –
just enough gas to meet the
need.
The ROTEX GasSolarUnit (GSU 520 S/
GSU 530 S) not only uses the power of
the sun for domestic hot water heating
but also for supporting the heating
system effectively.
If you decide not to incorporate a solar
installation at this time, the solar
support system of the ROTEX GasSolarUnit can easily be retrofitted.
If the sunshine is insufficient, or if the
GasSolarUnit does not need any more
heat, the feed pump switches off and
the entire Solar System drains into
the storage tank. The addition of
antifreeze is not necessary because if
the installation is not in use, the
collector surfaces are not filled with
water - another environmental
advantage!

Economical and effective
Since the system is unpressurised, the
components that would otherwise be
required, such as an expansion vessel,
pressure relief valve and heat
exchanger, are not required.
This not only saves money when
purchasing the installation, but also
increases security of operation.
Good for the environment

beneficial for the environment:
■ Lowest possible environmental

The domestic water heat exchanger,
made of stainless steel corrugated
pipe, extends over the entire depth of
the storage tank. The fresh water is
fed in at the lowest point of the
storage tank. From here it is directed
upwards in the stainless steel
corrugated pipe which acts as a heat
exchanger, in a spiral manner.
It is continuously heated as it passes
through the storage tank. This
arrangement produces defined
temperature statification with the hot
water preparation.

This stable temperature stratification
is a significant prerequisite for highly
effective utilisation of solar energy.
This always removes the coldest water
in the storage tank from the lowest
point of the tank, transports it to the
solar collectors on the roof and then
feeds it back into the storage tank via
a special stratifying charging system.
This permits optimum energy
exploitation in solar energy utilisation.

GSU 320 – Highest possible
hot water comfort
GSU 535 – Hot water with
no boundaries
The GSU 320 offers the maximum
output in the smallest space. It uses
the total tank volume of approx. 280 l
for heat storage and can thus
accommodate high demands for hot
water without any problems.
The GSU 535 is the ideal solution for
installations for high levels of heat and
hot water demand.
Here again solar energy utilisation
can be used for the preparation of hot
water. The GSU 320 is fitted with all
the connections required for solar
heating. Especially with the system for
ensuring optimum temperature
stratification in the storage tank.
[ 10 ]
Several units can be combined
together for this application. This adds
the resulting heat
output for heating and
for hot water output.
In this way, a system
comprising several
GSU 535 units can be
the economical,
efficient and waterhygienic perfect
solution for hotels, old

This means that the total heat
capacity of ca. 300/500 litres of
storage tank water is available for hot
water preparation, the hot water output is thus at a maximum.
When hot water is drawn off, using
the GSU 320 and GSU 535, a distinct
temperature stratification is produced,
and this maximises the volume of hot
water that can be removed.

Explanation: The specific water flow as defined in EN 625 is the domestic hot water flow which the GasSolarUnit can supply at an average temperature increase of 30 K
with two successive withdrawals of water of ten minutes duration each, assuming a charging temperature of 65 °C. An interval of 20 minutes is normally assumed
between the withdrawals. The GasSolarUnit acheives these values even with shorter intervals.

ROTEX EcoHybrid® –
the complete heating system.
What is EcoHybrid®?
The word "hybrid" originates from
Greek and means "mixed, from two
different origins".
A hybrid heating system allows the
different types of energy to work
together, such as heat pumps and solar
energy, but also allows other types of
energy to be integrated, such as oil,
gas, pellet, or even log burning boilers.
This means you are equipped to face
any contingencies in the future.
Consistent use of renewable
energies and efficiency that is
practically impossible to surpass.
