system
The ground as a heat source
Flat-plate collectors or geothermal probes extract heat from the
ground. The primary circuit (brine) transfers this heat to the cooling
circuit of the heat pump. There, the higher temperature level required
for the heating system is achieved.
Water as a heat source (well circuit)
The water circulating in the well circuit transfers the heat to the primary
circuit (brine). From here, heat is transferred in the same way as heat
extracted from the ground. For this reason, many brine/water heat
pumps can be converted to a water/water heat pump with a conversion
kit.
Yielding heat with geothermal collectors/geothermal probes
Yielding heat with geothermal collectors
The amount of energy that can be extracted from the ground depends
on various factors.
■ According to current knowledge, ground rich in clay with plenty of
water is a particularly good heat source.
Experience has shown that a specific heat extraction (cooling
capacity) of qE = 10 to 35 W/m2 ground area can be assumed as
annual average for operation all the year round (mono-mode) (see
also chapter "Design information").
■ The energy extraction rate for very sandy soil is lower. If in doubt,
an expert opinion should be sought.
Increasing solar irradiation and precipitation during the second half of
the heating season regenerate the cooled-down ground ensuring that
the ground "energy store" will again be available for heating purposes
during the forthcoming heating season.
Generally, the following must be observed:
■ Deep-rooted plants should not be located in the vicinity of the brine
pipes.
■ Never seal the surfaces above the geothermal collector. Sealing the
surfaces prevents the ground from being regenerated.

Yielding heat with geothermal probes
Under standard hydro geological conditions, an average extraction
capacity of 50 W/m probe length can be assumed for geothermal probe
systems (according to VDI 4640).
Boreholes:
■ Boreholes to a depth < 100 m are subject to approval from your local
water board.
■ Boreholes to a depth > 100 m must be approved by your local mining
board.
Drilling contractors certified according to the DVGW Code of Practice
W 120 should be engaged to carry out the drilling work. Viessmann
recommends the work to be carried out by the geothermal energy
department of Viessmann Deutschland GmbH (see "Manufacturer's
addresses" in the appendix).
Operating modes
The operating mode of heat pumps depends largely on the selected
or existing heat distribution system.
Subject to the individual model, Viessmann heat pumps reach a flow
temperature of up to 65 ºC. At higher flow temperatures or at very low
outside temperatures an additional heat source (mono-energetic or
dual mode operation) may be required to cover the heat load.
In a new build, any heat distribution system can usually be selected.
However, high seasonal performance factors can only be achieved in
heat pumps in conjunction with a heat distribution system with low flow
temperatures (max. 35 °C).
Mono-mode operation
In mono-mode operation, the heat pump alone covers the entire heat
load of a building to EN 12831. This operating mode requires that the
heat distribution system is designed for a flow temperature below the
max. flow temperature of the heat pump.
When sizing the heat pump, allowances must be made to cover power-
OFF periods and special tariffs provided by the power supply utility.
Dual mode operation
In dual mode operation, the heat pump system is supplemented during
heating operation by an additional heat source, e.g. an oil/gas boiler.
This heat source is controlled by the heat pump control unit.
Mono-energetic operation
Dual mode operation, where the additional heat source and the com-
pressor are operated electrically. An additional heat source could be
an instantaneous heating water heater in the secondary circuit.
In typical system configurations, the heating output of the heat pump
is designed for approx. 70 to 85 % of the maximum required heat load
of the building (in accordance with EN 12831). The heat pump covers
approx. 92 to 98 % of the annual heat load.

Cover ratio of the heat pump in % of the annual heat load (heating only)
of a standardised domestic building, subject to the heat pump heating
output in mono-energetic operation
Due to the low investment costs for the heat pump, compared to mono-
mode operation, operating a heat pump in mono-energetic mode offers
economic advantages, particularly in new builds.
Dual mode parallel operation
Subject to the outside temperature and heat load, the heat pump con-
trol unit starts the second heat source in addition to the heat pump.
In typical system configurations, the heating output of the heat pump
is designed for approx. 50 to 70 % of the maximum required heat load
of the building in accordance with DIN EN 12831. The heat pump cov-
ers approx. 85 to 92 % of the annual heat load.
Dual mode alternative operation
Above a certain outside temperature (dual mode temperature), the
heat pump covers the entire heat supply of the building. Below the dual
mode temperature, the heat pump switches off and the additional heat
source (oil/gas boiler) takes over the sole heat provision for the build-
ing. The changeover between the heat pump and additional heat
source is controlled by the heat pump control unit.
The dual mode alternative operating mode is particularly suitable for
existing buildings with conventional heat distribution and transfer sys-
tems (radiators).

ADual mode parallel operation
BDual mode alternative operation
Due to the lower investment costs for the entire heat pump system, the
dual mode operation is particularly suitable for existing boiler systems
in renovated buildings.
Note
With dual mode parallel operation, the heat source (ground) must be
sized, due to the longer running times (compared to dual mode alter-
native operation) so it can cover the entire output demand of the
building.
Power supply tariffs
Most power supply utilities offer special tariffs to enable the cost-effec-
tive operation of heat pumps.
Providing these special tariffs enables the power supply utility to tem-
porarily interrupt the power supply to heat pumps during peak times.
In mono mode operation, the power supply may be blocked for a max-
imum of 3 x 2 hours within a 24-hour period.In underfloor heating sys-
tems, the power-OFF periods have no noticeable effect on the room
temperature due to system inertia. With other systems, power-OFF
periods can be bridged by using heating water buffer cylinders.
The power supply to dual mode heat pump systems can be blocked
for a maximum of 1110 hours within the heating season. During such
times, the additional heat source can meet the entire heat demand of
the building.
Note
The ON periods between two power-OFF periods must not be shorter
than the previous power-OFF period.
There are no special tariffs available for uninterrupted power supply.
In this case, the heat pump power consumption is billed together with
the domestic or commercial power consumption.
Drying buildings (higher heat demand)
Subject to construction (e.g. monolithic), new buildings contain large
amounts of water held in tile or cement screeds, plaster finish etc.
This bound moisture must be evaporated through heating to prevent
damage to the building. This requires a higher heat demand compared
to the conventional heating of a building.
The heat pump with the primary source is not designed for the higher
heat demand required in such cases. This demand must be covered
by drying equipment provided on site or by an additional instantaneous
heating water heater (accessory).
Principles (cont.)
6VIESMANN VITOCAL 200-G

5442 496 GB

Screed drying
Top covers (such as tiles, parquet etc.) permit only minor residual
moisture in the screed prior to their application.
Screed drying also requires a higher heat demand. Air/water and brine/
water heat pumps cover this higher heat demand through a booster
heater designed for screed drying, e.g. an instantaneous heating water
heater.
In water/water heat pumps, it is generally sufficient to increase the
pump rate to cover the higher heat demand.
Coefficient of performance and seasonal performance factor
To assess the efficiency of the electrically operated compression heat
pumps, the EN 14511 standard specifies the coefficient of perform-
ance and performance factor parameters.
Coefficient of performance
The coefficient of performance ∊ is the ratio of the current heating out-
put to the effective power consumption of the appliance.
∊=PH
PE
PHHeat (W) per unit of time transferred by the heat pump to the heat-
ing water
PEAverage power consumption of the appliance within a specific
period, incl. power consumption for control unit, compressor, fuel
supply equipment and defrosting (W)
Modern heat pumps have a coefficient of performance between 3.5
and 5.5, i.e. a coefficient of performance 4 means that four times more
heat is available than the electrical energy consumed. The vast major-
ity of the heating energy originates from the heat source (air, ground,
groundwater).
Operating point
The coefficient of performance is measured at fixed operating points.
The operating point is specified by the inlet temperature of the heat
source (air A, brine B, water W) in the heat pump and the heating water
outlet temperature (secondary circuit flow temperature).
Example:
■ Air/water heat pumps
A2/W35: Air intake temperature 2 °C, heating water outlet temper-
ature 35 °C
■ Brine/water heat pumps
B0/W35: Brine inlet temperature 0 °C, heating water outlet temper-
ature 35 °C
■ Water/water heat pumps
W10/W35: Water inlet temperature 10 °C, heating water outlet tem-
perature 35 °C
The lower the temperature differential between the inlet and the outlet
temperature, the higher the coefficient of performance. To increase the
coefficient of performance, it is best to opt for the lowest possible flow
temperature, e.g. 35 ºC, with an underfloor heating system, as the inlet
temperature is subject to the ambient conditions.
Seasonal performance factor
The seasonal performance factor β is the ratio of the annual volume
of heat provided by the heat pump system to the overall electrical
power drawn by the heat pump system over the same period. This
includes the amounts of power used by pumps, control units etc.
β = QHP
WEL
QHP The amount of heat (kWh) delivered by the heat pump over the
course of a year
WEL The total electrical power (kWh) supplied to the heat pump sys-
tem during a year
1.2 Cooling
Utilisation of the primary source
Brine/water and water/water heat pumps can, during spring, summer
or autumn, utilise the temperature level of what is used as heat source
in winter as a heat sink, i.e. to cool the building with natural cooling.
In some heat pumps, the simultaneous operation of the compressor
enables active cooling, which uses the refrigerating capacity of the
compressor.
The heat generated is dissipated via the primary source (or a con-
sumer).
Underground temperatures are relatively constant all the year round.
In undisturbed ground, it is assumed that from a depth of 5 m, there
are only minor temperature fluctuations of ±1.5 K around an average
temperature of 10 °C.

Temperature progress in undisturbed ground subject to depth and time
of year
On hot days, buildings heat up through high outside temperatures and
solar irradiation. With the appropriate accessories, brine/water heat
pumps can use the low temperatures underground to dissipate heat
from the building to the ground via the primary circuit.
The heat exchanger connected in series separates the system. In
summer, the temperature level of the heat source (brine) is approx. 12
to 8 °C.
"Natural cooling"/"Active cooling"
Natural cooling is a very efficient cooling function, as cooling only
requires the operation of two heating circuit pumps. For this function,
the heat pump compressor stays off. During natural cooling operation,
the heat pump will only be started to produce DHW.
Natural cooling is possible with the following systems:
■ Underfloor heating systems
■ Fan convectors
■ Chilled ceilings
■ Concrete core tempering
The ambient air can only be dehumidified in conjunction with the nat-
ural cooling function if fan convectors are connected (condensate drain
required).
Cooling capacity
The capability of the natural cooling function cannot generally be com-
pared with that of air conditioning systems or chillers. The cooling
capacity depends on the heat source temperature, which itself is sub-
ject to seasonal fluctuations. Experience has shown that the cooling
capacity is higher at the beginning of summer than at the end.
In active cooling mode, the heat pump operates like a chiller and cools
the building with the available cooling capacity. The constant cooling
capacity available is subject to the output size of the heat pump.
With active cooling, the cooling capacity is significantly higher than with
natural cooling.
Regeneration of the ground
In heating mode, the heap pump extracts heat energy from the ground.
At the end of the heating season, the temperature near the geothermal
probe/collector is around freezing. By the start of the next heating sea-
son, the ground will be sufficiently regenerated. Natural cooling accel-
erates this process by extracting heat from the building and transfer-
ring it to the ground. The average brine temperature may increase
subject to the heat ingress into the ground probe during summer. This
has positive effects on the seasonal performance factor of the heat
pump.
1.3 Noise development
Sound
Human beings are capable of hearing sounds in the pressure range
from 20 ∙ 10–6 Pa (hearing threshold) to 20 Pa (1 to 1 million). The pain
threshold is at around 60 Pa.
Changes in air pressure are perceived provided they take place at a
rate of between 20 and 20,000 times per second (20 Hz to
20,000 Hz).

AStructure-borne noise
BAirborne noise
Structure-borne noise, liquid-borne noise
Mechanical vibrations present in equipment, such as machine and
building components as well as in liquids, are transmitted through them
and radiated out by them at different points as airborne noise.
Airborne noise
Sound sources (equipment in which vibrations are present) create
mechanical vibrations in the air that propagate in wave form and are
audible to the human ear at different levels.
Sound power level and sound pressure level
ASource of sound (heat pump)
Emission site
Measured variable: Sound power level LW
BLocation of incoming sound emission
Immission site
Measured variable: Sound pressure level LP
Sound power level LW
This describes the entire sound emissions in all directions emanating
from the heat pump. It does not depend on the surrounding conditions
(reflections) and is a value that can be used for direct comparisons of
sound sources (heat pumps).
Sound pressure level LP
The sound pressure level is a measure to assist orientation regarding
the volume of noise perceived by the ear at a specific location. The
sound pressure level is largely defined by the distance and the char-
acteristics of the surroundings and is thus dependent upon the meas-
uring location (often at a distance of 1 m). Standard measuring micro-
phones measure the sound pressure directly.
The sound pressure level is the variable that is used to assess imis-
sions from individual systems.
