TABLE OF CONTENTS
The desire for warmth in our homes is as strong today as it always has been. However, these days, when we consider heating issues, we take into account
the effect on the environment as well as how economic a particular system may be.
The development of modern heat pump technology proves that both can make ideal partners. Heat pumps cleverly exploit latent energy in air, water and in
the ground and convert his energy into heat.
This form of energy utilisation is particularly responsible because it yields benefit from the environment without destroying it.
Mature technology for optimum convenience
For more than 20 years, STIEBEL ELTRON has been investing time and effort in the development
of highly efficient heat pumps. Today, you can reap the benefit by investing in reliable and fully
developed technology, which offers you every available convenience. In the shape of a range of
heat pumps for almost every conceivable demand in the field of heating technology combining
comfort and economy.
Heat pumps protect the environment whilst saving you money. The ratio of heating energy gained
to energy spent speaks for itself: 1 kWh electrical power can yield - subject to energy source - up to
5 kWh useful energy – from the air, from groundwater or the ground of your property itself.
In other words, energy that doesn’t cost you a penny to produce, which also protects the
We are responsible
As manufacturers of products for the heating, ventilation, air conditioning and DHW sector, we feel a responsibility towards protecting the environment.
Apart from seeking to meet our customers’ demands, it is our ambition to translate the high quality standards we apply to our products in the most
environmentally responsible way, using innovative and alternative technologies. Our heat pumps are part of the STIEBEL ELTRON modular design range,
an important part of our strategy towards achieving our stated goal.
Time for contemplation
It seems that we have forgotten how to handle the treasures of this world with care. We are only stewards or guardians of the world for future generations.
Reduce emissions, protect resources
The combustion of fossil fuels such as natural gas or fuel oil create emissions, amongst them, carbon dioxide, which is partially responsible for environmental
damage. The substantial increase in other combustion residues also gives rise to concern, as the global warming it causes disturbs the sensitive climatic
Heat pump technology makes an important contribution to environmental protection.
A simple principle - as yet unbeaten
Comparable to the principle of a refrigerator, the heat pump function is simplicity itself: It withdraws latent energy
from the air, water or ground and transfers it to the heating system. This free environmental energy is initially
routed to the heat exchanger (evaporator) of the heat pump. The evaporator contains the liquid refrigerant
(process medium), which absorbs the heat from the energy source and, in the process, evaporates. The
compressor pulls the gaseous process medium inside where it is compressed. As pressure rises, the
temperature increases. A second heat exchanger (condenser) then ensures that the heat is transferred to the
heating circuit. The expansion valve finally provides the pressure reduction, and the cycle starts again.
That’s how free energy from the environment is converted into useful heat.

Summer or winter – inside or out
Suitable control units and solar buffers enable an optimum combination with a solar heating system. This utilises
free environmental energy at every level.
The WPL utilises ambient air down to –20 °C, to provide comfortable heat and hot water with a flow temperature
up to 60 °C. The WPL is easily installed, not only indoors, but also outside, making it particularly suitable for
modernising older properties. The galvanised casing is tough enough to resist even the hardest weather conditions
and other environmental influences. The “old” boiler room can surely be put to better use. How about a new hobby

• Use with under floor heating or radiator systems: Low temperature heating systems offer higher performance
• For complete heating water provision up to + 60 °C, even at – 20 °C outside temperature
• Simple installation, a good idea even in modernisation projects
Economical and efficient high performance - all year round
Innovative and convenient: The WPF compact heat pump
Compact WPF 5..13 SOL heat pumps represent an intelligent system which utilises free energy from the
environment and additional solar energy for the production of domestic hot water (DHW) and to backup central
heating. Thanks to its outstanding sound insulation, it does not need to be banished to the cellar, but can be
installed in a hobby or utility room instead. The new high performance refrigerant, R410A, also makes no demands
on ventilation. The WPF models already include almost all functional elements for your heating system. The
attractively designed casing houses the diverter valve for DHW loading, the immersion heater element, the WPM
control unit and much more.

• Four sizes for detached and two-family homes
• Energy source: Ground. Application range: – 5 °C to + 20 °C brine temperature
• Suitable for well installations, ground collectors/ground probes
• High annual performance factor
• Low installation costs
• Including integral solar and heating system controller
• Extremely quiet operation
Your choice: Ground probe or ground collector
Whether ground probe or ground collector – the decision is subject only to the size of your property and the ground
For smaller properties, ground probes, which penetrate the earth to a depth of 100 m, are more suitable. The
ground collector simply requires more space - because it is laid at a depth of 1.2 to 1.5 m. A detached house with a
heat demand of approx. 8 kW requires a collector area of approx. 250 m2
How it works:
Inside the evaporator, the brine (anti-freeze/water mixture) heated under ground, transfers heating energy to the refrigerant. This causes the refrigerant to
evaporate, the compressor increases the pressure and thereby the temperature, enabling a second heat exchanger to transfer heat to the heating water.
This liquefies the refrigerant again, and pressure is reduced by the expansion valve. This transfers 75 % of the heating energy from the ground into the

Optimum utilisation of groundwater energy
The four sizes of WPF heating system heat pumps cover every demand for detached and two-family homes. The
WPF delivers exemplary performance - not only in brine/water, but also in water/water operations. Pre-requisites
for the water/water operation are two wells (delivery and return wells) and groundwater in adequate quantity and
quality. This energy is transferred to the heating water via the heat exchanger and is utilised to optimum benefit.
Subject to heat demand, the heating water can be raised to between 15 °C and 60 °C. The groundwater inlet
temperature range lies between +7 °C and +20 °C. In our latitudes, the groundwater temperature remains
relatively constant, even in harsh winters.
The integral heat pump regulator enables a solar heating system to be connected to the heat pump for DHW
loading. The SOL version loads the SBK 600/150 solar combination cylinder, thereby providing optimum utilisation
of solar energy for DHW loading and central heating. Combined with a solar heating system from STIEBEL
ELTRON, they create an unbeatable team which further reduces energy costs.

The four sizes of WPF heating system heat pumps cover every demand for detached and two-family homes. The WPF delivers
exemplary performance - not only in brine/water, but also in water/water operations. Pre-requisites for the water/water operation are
two wells (delivery and return wells) and groundwater in adequate quantity and quality. This energy is transferred to the heating water
via the heat exchanger and is utilised to optimum benefit.
How it works:
The water/water heat pump requires two well holes (delivery and return well). Warm groundwater is extracted from the delivery well and cooled down as low
as 5 °C. Afterwards it is reintroduced into the groundwater via the return well. The energy extracted from the groundwater (up to 80 %) can cover nearly
100 % of your heating requirements for a full 12 months of the year.

More output: WPF..M modular versions
More output: WPF..M modular versions
WPF..M systems are extremely flexible. Subject to requirements, they can be used as water/water or as brine/water heat pumps.
Three basic models with a rated output of 10, 13 and 18 kW (brine operation) reliably supply living space with free energy from the
environment and efficient heat – for central heating and DHW alike. Combining up to six heat pumps and two controllers can achieve
an output of approx. 100 kW. The WPF..M series is based on a modular design, which is flexible enough to meet a variety of
performance needs, and can be matched to the most wide ranging requirements. For example, these heat pumps can also be used
for heating swimming pool water. As an alternative, the compact WPF series offers just the right package for use in conventional
detached or two-family homes (see pages 8–11). Naturally, both systems can be used in water/water or in brine/water operations.
