OCHSNER Heat pumps
FOR YOU AND YOUR
ENVIRONMENT
page 2
The choice of the right heating system for one’s own home is an important decision
lasting for decades. The most important requirements for a heating system are: highest
efficiency and thus lowest heating costs, comfort, operational safety, the best possible
environment protection and long life.
FOR THE ENVIRONMENT AND YOUR POCKET
Heat pumps use the sun’s energy stored in the air, in water or the
ground. Whoever decides on a heat pump not only saves CO2,
but also has less to worry about increasing oil or gas prices or fear
of problems in supply.
YOUR DECISION TODAY ALREADY AFFECTS THE
AMOUNT OF YOUR BUILDING COSTS
The efficiency values of an OCHSNER heat pump help you
to already reduce the total costs of your building and/or system
engineering. With a high-efficiency OCHSNER heat pump you
are fulfilling the regulations for residential construction as well as
the relevant Standards. This is achieved even without investing in
heat insulation or system engineering.
THE RIGHT CHOICE AND THE SAFEST INVESTMENT
Investing in a high-quality heat pump system these days increases the value of your building and guarantees immediately high
return in the form of running cost savings.
Additionally, the installation of a heat pump system is subsidised
in many areas. Information can be found at www.ochsner.com.
A heat pump gives you independence, needs little maintenance,
and is clean and non-odorous. Fuel storage rooms, chimney
sweeps or boiler servicing is unnecessary.
FOR NEW BUILDINGS AND HEAT SYSTEM
RENOVATION
Heat pumps are suitable both for new buildings and for their
renovation. It is of no importance whether your building has
under-floor heating or radiators – many years ago OCHSNER
was the first manufacturer to bring out a heat pump range up to
65°C flow temperature. This has now even been increased to
68°C. Thus, existing heating systems can also be operated with
conventional radiators.
HEAT PUMP WITH OWN-GENERATED ENERGY
Using an OCHSNER heat pump you can use the electricity from
your own photovoltaic system as the priority energy for space
heating and hot water. The input into the grid will only take place
once the whole storage tank is heated up.
OCHSNER heating systems leave nothing to be desired

OCHSNER IS ERP READY
The ErP ready Symbol shows that OCHSNER is already meeting the requirements of obligatory labelling according to the
Eco-Design Directive - valid from September 2015 onwards.
OCHSNER’s cutting-edge technology in the heat pump and storage tank field is thus today providing solutions for tomorrow’s
demands. Using OCHSNER heat pumps, you can achieve COPs
which no other heating system can provide.
COMPLETE PRODUCT RANGE – FOR HEATING,
COOLING AND HOT WATER
OCHSNER supplies a complete product range from 2 to 1,000
kW for heat sources air, ground or water. OCHSNER heat pumps
can be equipped with the additional active cooling function – by
reversing the refrigerant circuit, resulting in a quiet and pleasant
room conditioning without draughts by means of the existing
heat distribution system (e.g. wall heating, under-floor heating or
special convectors). Hot water can be heated either in connection with the heating heat pump or by using the hot water heat
pump of the EUROPA Series.
MUCH MORE THAN JUST A HEATER
The demands on a modern heating system are numerous and
varied. Alongside the basic functions such as heating, cooling (optional) and hot water heating, OCHSNER provides the
opportunity of heating your swimming pool, of integrating your
photovoltaic system in the heat pump, internet connection,
building management system, bivalent operation with other heat
generators and much more. The modern OCHSNER OTE control
makes it possible.

OCHSNER IS SMARTGRID READY
By means of the SmartGrid functionality, the favourable tariffs of
future electricity networks can be used for heat pump operation.
These tariffs result from the electricity surpluses which naturally
accompany the generation of electricity from renewable energy
sources such as wind and solar. Smartgrids serve as peak compensators; Smartgrid-capable heat pumps switch on only when
surplus electricity is available at a favourable tariff, and store this
energy in the form of hot water.
CONFIRMED EFFICIENCY AND PROVEN QUALITY
OCHSNER
Heat pumps of the GMLW Series have been achieving efficiency records, peak values for noiselessness and ensuring lowest
heating costs. OCHSNER is also ahead in terms of energy
efficiency with ground heat sources. Look out for the ehpa-seal
of quality when buying a heat pump. Only those heat pumps that
have been tested under strict test conditions by independent
institutes and whose manufacturers fulfil the requirements as far
as service and documentation have the right to carry this seal.
By-the-way, OCHSNER heat pumps are manufactured exclusively
in Austria using the highest quality components.
With the power of natural heat sources
HOW A HEAT PUMP
WORKS
HOW DOES A HEAT PUMP WORK?
The heat pump converts low temperature heat into heat of
higher temperature – even in Winter at well below 0°C. This
takes place in a closed circuit process through continuous
changing of the aggregate condition of the refrigerant (1=evaporation, 2=compression, 3=condensation, 4=pressure release.)
SELECT THE SYSTEM MOST SUITABLE FOR YOU
OCHSNER stands for quality – this you can put your trust in.
High investment in Research and Development, long-term
experience and components of the highest value make this
possible. However, the system can only be perfect if it has been
planned correctly to your requirements and wishes. This includes
the selection of the correct heat source and also the right heat
pump product for your system. Please read more on this on the
following pages.
The heat pump uses the sun’s energy stored in Mother Nature’s
heat sources and releases this plus the drive energy in the form
of useful heat to the heating and warm water circuits.

THE HEAT PUMP AS ENERGY MULTIPLIER
A heat pump’s coefficient of performance (COP) indicates how much useful energy is supplied from one
unit of drive energy. A COP of 4 means that 4 kW heating energy can be produced with 1 kW
of electricity. 3 kW are provided free-of-charge from the sun and the environment.

Energy supplies - direct from nature
THE HEAT SOURCES
5 to
65 kW
AIR
GROUND HEAT
Due to the further development of the horizontal-split system
technology, OCHSNER has made the use of air as a heat source
economical as well. Air is available everywhere and in unlimited
supply.
The ground is a free-of-charge and abundant heat store and thus
represents an ideal heat source.
Using flat plate collectors, stored solar energy is mainly used
– constantly and completely independent of the time of day or
night. If installed correctly, sufficient source energy is available
even in the deepest of winters.
This system is also especially suitable for the renovation of
heating systems in existing buildings, where retroactive
installations in the ground are mostly undesirable or too costly.
Due to OCHSNER’s technical innovation, the heat source air
can be efficiently used, even at low outside temperatures. High
operational safety and low noise levels especially characterise
this product.
The heat source air is also ideally suited for use in bivalent operated systems as well.
ACTIVE COOLING
During active cooling operation, the warmth from inside the building is exhausted to the air by means of the external evaporator–
which then technically becomes a condenser. Active cooling is
possible with all Models in the GMLW- and ELW-Series
page 6
5 to
18 kW
DIRECT EXPANSION
Using direct expansion systems (also known as direct
evaporation), you can achieve the lowest operating costs of all
known ground collector systems known today. They use up to
4/5 free environmental energy!
The chlorine-free and ozone-neutral refrigerant in the heat pump
circuit extracts the heat direct from the ground by means of the
double-walled, seamless tubes of the flat-plate collector (copper
with PE-protective sheath). This takes place via the direct evaporation of the refrigerant in the flat-plate collector.

99 kW
5 to

WATER
GROUND HEAT –
BRINE
If ground water is available at a reasonable depth and in sufficient
quantity, one can reach the highest seasonal performance
factors. A constant temperature of 8 – 12°C guarantees an
optimum heating operation.
Using this system, the ground heat is extracted by means of a
brine circuit and then transferred to the heat pump.
Two wells are necessary for this: a source well and a sink
well. The sink well should be located at least 15 metres from the
source well in the direction of the ground water flow.
• If the garden area is sufficient, flat-plate collectors are the
least expensive solution. The area to be laid is dependent upon
the type of construction and the insulation properties of the
house as well as the composition of the soil.
The amount of ground water necessary for 1 kW heating performance is around 250 litres per hour. The yield is to be established by means of a continuous pump test. Certain limiting values
for the contents of the water must not be exceeded or fallen
below. Therefore, a water analysis is to be carried out. Approval
from the water authorities is often necessary.
ACTIVE OR PASSIVE COOLING
Water as a heat sink is also suitable both for active as well as
passive cooling of the building.
Brine ground collectors can be laid in three ways:
• As an alternative, spirally formed deep-trench collectors can
be installed as they require somewhat less area.
• Ground probes can also be inserted in the ground by means
of deep drilling. These will normally be placed at around 100
metres depth each and are ideally suitable for buildings with
little ground space. Approval from the water authorities is
necessary.
ACTIVE COOLING
During active cooling operation in summer, heat is “pumped” out
of the living areas and into the ground by means of the existing
heating system. In active cooling operation, the maximum cooling
performance is fully available, even after week-long heat waves.

are, with regard to energy efficiency, noise development and
operational safety, the ideal solution for highest demands. In the
split appliances of the GMLW Series, the air heat exchanger is
mounted horizontally (Horizontal split evaporator).
The increased energy efficiency is the result of the optimum
evaporator construction – for instance the large heat exchanger
area and the slow-running fans. This outdoor unit is connected by
connection pipework to the heat pump which is installed
protected in the building.
CUTTING EDGE CONTROL TECHNOLOGY
The OCHSNER OTE interior climate manager (see page 24)
provides highest comfort levels, maximum energy efficiency and

are also available with cooling function.
The OCHSNER GMLW Series is distinguished by highest efficiency, long working life
and especially silent running.

OCHSNER Horizontal Split System – GMLW Series
HEAT SOURCE AIR USED
WITH HIGH EFFICIENCY
The high-efficiency horizontal split evaporator extracts the
necessary amount of warmth from the outside air, whereby an
optimised, automatic de-icing system keeps the evaporator, if
required, ice-free without using much energy. Our horizontal split
evaporators are manufactured in exclusive housings.
Here, OCHSNER grants a 10-year guarantee against rusting
through.
Due to the sizing and optimum appliance construction, a maximum of warmth is absorbed from the air. Even at extreme temperatures below zero. No other appliance on the market offers
such large heat exchanger areas! Low-speed special fans provide
whisper-quiet operation with the highest energy efficiency.
Furthermore, a continuous stage evaporator output adjustment
and also the heat pump performance is achieved by the fully-modulating fan operation.
A further advantage of the split evaporator’s horizontal construction is that the exhaust air is blow upwards – thus causing no cold,
unpleasant draughts towards the neighbours or into one’s own
garden.
The heat pump installation, with its core element, the compressor, takes place protected from the elements in the building. The
installation of the evaporator is in the free air from which it takes
its warmth without losses.
The connection of the externally installed evaporator to the internally installed heat pump is very simply carried out by means of
insulated copper pipes and a wiring harness. These are normally
laid under the surface of the ground in a duct and are thus, even
retroactively (heating system renovation) installed without any
problem. In order to maximise operational safety in extreme
weather conditions, “Thermodynamic de-icing“, “Anti-Bloc“ and
“inverted operation” were developed.
CONFIRMED TOP VALUES
The Golf (GMLW) plus heat pump, along with the OCHSNER split
evaporator achieved a COP of 4.4* and holds the ehpa seal of
quality (see www.wpz.ch). Furthermore, this series achieved the
lowest noise levels and are thus the quietest air/split heat pumps
on the market.
SOUND REDUCTION BY MEANS OF
FLUSTER-MANAGEMENT
Thanks to the new, unique and patented Fluster-Management,
the noise emission of the Ochsner VHS-M evaporator is reduced
to an absolute minimum. Thus, they are hardly heard any more,
even during operation.
SILENT MODE
In silent mode, the speed of the fan is reduced, dependent on
the outside air temperature, by a fixed proportional function.
This is to ensure that, for example, in the summer in hot water or
pool heater operation, the already extremely low noise emission
is reduced once again. This feature is supplied as standard by
Ochsner.
SUPER SILENT PACKAGE
The Super Silent Package is available as an option for all Models
in the GMLW Series and is recommended for especially sensitive
conditions. The constructive optimisation, derived from the
aerospace industry, results in an additional noise reduction
of -3 dB(A).
*Peak value – measured on a GMLW 14 plus Model at 2°C outside temperature and a water temperature
of 35°C to the relevant testing Standard EN 14511.

Heat source ground
UNLIMITED ENERGY
FROM THE GROUND
When using the heat source ground, flat-plate collectors or ground probes extract the
sun’s energy stored in the ground.
Depending on the heat carrier medium in the ground collector,
a differentiation is made between the systems brine and direct
expansion.
This leads to even higher operational safety due to fewer
components, as well as better efficiencies and thus lower
running costs.
In the direct expansion system, standard flat-plate collectors
are used. The brine circuit, consisting of circulation pump, heat
exchanger and expansion vessel, which is necessary for brine
systems, can be dispensed with.
OCHSNER was a pioneer in the introduction of this technology
30 years ago. Thousands of installed systems that have been
running fault-free for decades are proof of this competence and
experience.

HEAT SOURCE WATER
HIGHEST PERFORMANCE
WITH THE POWER OF
WATER
Using ground water as the heat source, heat pumps reach their highest COPs.
Ground water has a more or less constant temperature between 8 and 12°C
throughout the year.
Thus, the temperature level, compared with other heat sources,
must be raised less in order to be used for heating purposes.
The use of ground water as heat source for the heat pump must
be approved by the water authority. When applying for a permit,
the well-driller, the drilling company or your OCHSNER system
partner will be glad to be of assistance.
Sufficient quantities of water
Several prerequisites must be fulfilled in order to be able to use
ground water as a heat source:
Source and sink wells

In order to extend the working life of the heat pump compressor,
OCHSNER recommends the use of special heat pump separating
tanks. These are ideally tailored to the heat pump due to their
large connection dimensions.
HEAT PUMP FRESH WATER MODULES
Heat pump fresh water modules are to be treated as identical to
the Unifresh® as far as functionality is concerned as, here as well,

OCHSNER
STRENGTH
FROM
TRADITION
The economical use of limited, non-renewable
resources and the reduction of emissions have
to be our common target. OCHSNER has the
vision of using environmental energy to
contribute to tackling our communal national
and global energy future.
COMMITTED TO
PROGRESS
The OCHSNER Wärmepumpen GmbH was founded in 1978 and since the beginning has been characterised by energy consciousness, pioneer spirit and innovation. As one of the first manufacturers in Europe, OCHSNER began the first industrial production of heat
pumps and is today internationally ranked as one of the technology leaders in the industry. Manufacturing takes place exclusively in
Austria.
The original OCHSNER company was founded as early as 1872 in Silesia. The manufacturing program was limited at first to appliances
and pumps. From 1946 to 1992, the Linz factory was known for its technical achievements in the field of process pumps and compressors. Notable customers included international plant construction companies as well as the US-Navy and NASA. The compressor
production program comprised both piston and screw compressors up to 500 kW.
Since 1992, the OCHSNER company has been concentrating exclusively on the heat pump sector. Karl Ochsner heads the company as Managing Director together with his father, Karl Sr. OCHSNER is in the meantime celebrating its 143rd anniversary.
