“Dismantling”.
Operating principle of heat
pumps
Heat pumps operate on the principle of a refrigerator:
the same technology, only with the opposite eect. The
refrigerator extracts heat from foods, which is released
into the room through ns on the back.
The heat pump extracts heat from our environment:
air, earth or ground water. The extracted heat is con-
ditioned in the unit and supplied to the heating water.
Even when it is extremely cold outside, the heat pump
draws enough heat to heat a house.
Example: drawing of a brine/water heat pump with oor
heating:
4⁄4= usable energy
ca. 3⁄4= environmental energy
ca. 1⁄4= external electrical energy
Area of utilization
Taking into consideration the ambient conditions, limits
of application and the applicable regulations, every he-
at pump can be utilized in new or existing heating sys-
tems.
Overview “Technical data/scope of delivery”.

683050003aUK – We reserve the right to modify technical specifications without prior notice. © Novelan
Heat quantity recording
In addition to the proof of the unit’s eciency,
EEWaermeGalso meets the demand for a heat quantity
recording (hereafter refered to as HQR). The HQR is
mandatory with air/water heat pumps. With brine/
water and water/water heat pumps, a HQR may only
be set up when a forward ow temperature of ≥ 35 °C
has been reached. The HQR must record the total warm
energy release (heating and hot water) in the building.
In heat pumps with heat quantity recording, the analysis
is conducted by the regulator. The regulator displays
the thermal energy that is exchanged from the heating
system in kWh.
NOTICE.
Variant models are available, either with or wit-
hout heat quantity recording.
Operation
Your decision to purchase a heat pump or a heat pump
system is a long-term contribution to protecting the en-
vironment through low emissions and reduced primary
energy use.
You can operate and control the heat pump system wi-
th the control element of the heating and heat pump re-
gulator.
NOTICE.
Make sure that the control settings are correct.
Operating manual of the heating and heat
pump regulator.
To ensure that your heat pump or heat pump system
operates eciently and ecologically, the following are
especially important:
€ENERGY SAVING TIP
Avoid unnecessarily high ow temperatures.
A lower ow temperature on the hot water side
increases the eciency of the system.
€ENERGY SAVING TIP
When letting in fresh air, do not leave windows
open for an extended period in order to save
energy and reduce your heating costs.
Cooling function
The cooling function is available only for heat pumps
with the model designator K.
It is not possible to retrot heat pumps for cooling wi-
thout this designator. For the model designator, please
refer to the purchase documents. It is also on the rating
plate attached to the outside of the unit.
The cooling function is based on the principle of passive
cooling. An existing low temperature level is mixed to a
temperature above the dew point and transferred to the
heating medium by means of a heat exchanger. The he-
at pump remains switched o during cooling; only the
circulating pumps for the heating circuit and the heat
source are in operation.
The cooling power depends on the heat source tem-
perature, which varies seasonally. For example, if the
ground stored more heat toward the end of the sum-
mer, the cooling power of a brine/water pump is redu-
ced.
The eectiveness of passive cooling is generally not
comparable to that of an air conditioning system.
NOTICE.
The use of the passive cooling function requires
oor or wall heating.
THE ROOM THERMOSTAT FOR THE COOLING
FUNCTION
The room thermostat is used to switch the cooling func-
tion on and o:

UTILIZATION OF THE COOLING FUNCTION
The heating and heat pump regulation program acti-
vates the cooling function only if the following condi-
tions are fullled:
•Heat pump model must have integrated cooling
function.
•Room thermostat for the cooling function must
be switched on.
•Temperature of the heat source must be ≥ +5 °C.
•Heat pump must not currently be occupied with
“heating” or “water heating”.
If the heat pump regulation program sends the
command “water heating” to the heat pump, the
cooling function of the heat pump automatically
stops as long as the water is heating.
•The “Automatic” setting must be selected on the
control element under “Operating mode: coo-
ling”.
•The outdoor temperature release set on the con-
trol element must be exceeded.
Operating manual of the heating and heat
pump regulator.
The cooling function can be used in two variants:
Variant 1:
Manual switching from heating to cooling ope-
ration (and vice versa). This variant operates at a
pre-set forward ow temperature.
Operating manual of the heating and heat
pump regulator.
Variant 2:
Automatic switching from heating to cooling
operation (and vice versa). This variant can ope-
rate using a cooling curve.
NOTICE.
Variant 2 is possible only if a Comfort board
(available at extra charge) is built into the hea-
ting and heat pump regulator.
Comfort board operating manual.
Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and household cleaning products.
Do not use cleaning or care products that contain ab-
rasives, acids and/or chlorine. Such products would de-
stroy the surfaces and could also damage the technical
components of the unit.
Maintenance of the unit
The cooling circuit of the heat pump requires no regu-
lar maintenance.
According to EU regulation (EC) 842/2006 of May 17,
2006, leak inspections and maintenance of a log book
are required by law for certain heat pumps!
The criteria for conducting leak inspections and
maintaining a log book are based on the hermetic
impermeability of the cooling circuit and the refrigerant
capacity of the heat pump! No log book is required for
heat pumps with a refrigerant capacity of < 3kg. With
all other heat pumps, the log book is included with all
other delivered materials.
Log book for heat pumps, Section “Information
on use of the log book”.
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps,
lters, dirt traps) should be inspected as well as cleaned
as needed - at the very least annually - by a qualied
heating or cooling system technician.
It is a good idea to have a maintenance contract with
a heating installation company. The company will con-
duct the required maintenance at regular intervals.
CLEANING AND RINSING OF UNIT COMPONENTS
CAUTION!
Unit components may be cleaned and rinsed
only by customer service personnel autho-
rized by the manufacturer. Use only liquids
recommended by the manufacturer.
Rinsing of the liqueer with chemical clea-
ning agents must be followed by neutraliza-
tion of residue and intensive rinsing with wa-
ter. Always observe the technical data of the
manufacturer of the heat exchanger.

advances, but all these technical renements require
the system to be operated with correctly lled heating
water. The heating water not only aects the eciency
of the system, but also the life of the heat generator and
the heating components of a system.
The guide values of VDI 2035 Part I and Part II must
therefore be complied with as minimum requirements
for proper operation of the systems. Our practical
experience has shown that the safest and most trouble-
free running of the systems is achieved with so-called
low-salt operation.
VDI 2035 Part I gives important information and
recommendations regarding scaling and its prevention
in heating and domestic hot water heating systems.
VDI 2035 Part II primarily deals with the requirements for
reducing heating water corrosion in hot water heating
systems.
PRINCIPLES OF PART I AND PART II
The occurrence of scaling and corrosion damage in hot
water heating systems is low, if
- proper planning and commissioning is carried out
- the system is closed in corrosion terms
- adequately dimensioned pressurising is integrated
- the guide values for the heating water are complied
with
- and regular servicing and maintenance are carried out.
A system log should be kept, in which the relevant
planning data is entered (VDI 2035).
DAMAGE THAT CAN OCCUR IN CASE OF NON
COMPLIANCE
- Malfunctions and the failure of components (e.g.
pumps, valves)
- Internal and external leaks (e.g. from heat exchangers)
- Cross-section reduction and blockaging of components
(e.g. heat exchanger, pipes, pumps)
- Material fatigue
- Gas bubbles and gas cushion formation (cavitation)
- Negative eect on heat transfer (formation of coatings,
deposits) and associated noises (e.g. boiling noises,
ow noises)
LIMESCALE  THE ENERGY KILLER
Filling with untreated drinking water inevitably
leads to the precipitation of all calcium as scale. The
consequence: limescale deposits form on the heat

RINSING AND FILLING THE HEAT SOURCE
Contamination and deposits in the heat source can cau-
se malfunctions.
Rinse heat source system thoroughly…
Thoroughly mix the anti-freeze agent, available as
an accessory, with water at the required ratio. Add
only anti-freeze mixed with water to the heat sour-
ce…
ATTENTION
The concentration of anti-freeze in the water
must be at the level specied for your model.

WATER QUALITY OF THE FILL AND ADDITIONAL
WATER IN HOT WATER HEATING SYSTEMS
ACCORDING TO VDI 2035 PART I AND II
Use of modern, energy-ecient heat pump systems
is becoming increasingly widespread. Their ingenious
technology enables these systems to achieve very good
eciencies. The decreasing space available for heat
generators has led to the development of compact
units with increasingly smaller cross-sections and high
capacities. This means the complexity of the systems
and the material diversity are also increasing, which
plays an important role especially in their corrosion
behaviour. Novelan ensures continuous technological

ON THE SAFE SIDE WITH LOWSALT OPERATION
The problems listed above do not occur at all with
low-salt operation, as neither corrosive salts such as
sulphates, chlorides and nitrates nor alkalising sodium
hydrogen carbonate are in the heating water. The
corrosive properties of deionised water are very low
and in addition, fur cannot form in the boiler. This is the
ideal approach for closed heating circuits, in particular,
because low oxygen input into the heating circuit can
also be tolerated.
In general, when the system is lled with deionised
water, the pH value sets itself within the ideal range
due to “self-alkalinisation”. If necessary, a pH value of 8.2
can be very easily alkalised by adding chemicals. In this
way, optimum protection of the entire heating system is
achieved.
MONITORING
Analytical recording and monitoring of the relevant
water values and the added active conditioning
substances is of decisive importance. Therefore, they
should be monitored regularly using appropriate water
test equipment.
Rinse heating circuit system thoroughly…
ATTENTION
Do not exceed a pressure of 2.5 bar when rin-
sing the unit. The drain line of the heating cir-
cuit safety valve must be closed before rinsing
and lling.
NOTICE.
Rinse heat pump and heating circuit for about 5
minutes.
Fill heating circuit.
CLEANING AND RINSING OF UNIT COMPONENTS
ATTENTION
Unit components may be cleaned and rinsed
only by customer service personnel authorized
by the manufacturer. Use only liquids recom-
mended by the manufacturer.
Rinsing of the liqueer with chemical cleaning
agents must be followed by neutralization of re-
sidue and intensive rinsing with water. Always
observe the technical data of the manufacturer
of the heat exchanger.
transfer surfaces of the heating. The eciency falls and
the energy costs rise. A rule of thumb is that 1 millimetre
of limescale deposit causes an energy loss of 10%. In
extreme cases it can even cause damage to the heat
exchangers.
WATER SOFTENING TO VDI 2035  PART I
If the water is softened before the heating is lled,
in accordance with the VDI 2035 guidelines, no scale
can form. This eectively and permanently prevents
limescale deposits and the resulting negative eects on
the entire heating system.
CORROSION  AN UNDERESTIMATED PROBLEM
VDI 2035, Part II, deals with the problem of corrosion.
Softening the heating water can prove to be insucient.
The pH value can signicantly exceed the limit of 10. pH
values higher than 11 can set in, which even damage
rubber seals. The VDI 2035, Part 1 guidelines are fullled,
however, VDI 2035, Part 2 suggests a pH value between
8.2 and maximum 10.
If aluminium materials are used, which is the case in
many modern heating systems, a pH value of 8.5 must
not be exceeded, because otherwise there is a threat
of corrosion – and aluminium is attacked without the
presence of oxygen. Therefore, apart from softening
the heating ll and additional water, the heating water
should also be appropriately conditioned. This is the
only way to comply with the VDI 2035 requirements and
the recommendations and installation instructions of
the heat pump manufacturer.
Part 2 of VDI 2035 also points out the reduction in total
salt content (conductivity). The risk of corrosion is far
lower if deionised water is used than is the case if the
system is operated with salty, i.e. softened water.
Even if the water has been softened beforehand, it
contains dissolved, corrosion-promoting salts, which act
as electrolytes due to the use of dierent materials in
the heating system and therefore accelerate corrosion
processes. This can ultimately result in pitting.
Contamination and deposits in the heating circuit can
cause malfunctions
RINSE, FILL AND BLEED THE HEATING CIRCUIT
