1.4 Energy-efficient use of the heat
pump
By operating this heat pump, you are helping to protect the en-
vironment. A prerequisite for energy-efficient operation is the
correct design of the heat source system and heating system.
It is particularly important for the efficiency of a heat pump to
keep the temperature difference between heating water and
heat source as small as possible. For this reason, it is advisable
to design the heat source and heating system very carefully. A
temperaturedifference of approximately one Kelvin (1 °C) in-
creases the power consumption by around 2.5 %. When de-
signing the heating system, it should be borne in mind that spe-
cial consumers such as domestic hot water preparation should
also be taken into consideration and dimensioned for low tem-
peratures. Underfloor heating systems (panel heating) are
optimally suited for heat pump use on account of the low flow
temperatures (30 °C to 40 °C).
It is important to ensure that the heat exchangers are not con-
taminated during operation, as this increases the temperature
difference, which in turn reduces the COP.
When set correctly, the heat pump manager is also an essential
factor in the energy-efficient use of the heat pump. Further in-
formation can be found in the heat pump manager operating
instructions.
2 Intended use of the heat
pump

2.1 Area of application

The air-to-water heat pump is intended exclusively for heating
or, depending on the device, also cooling heating water. It can
be used in new or existing heating systems.
The heat pump is suitable for mono energy and bivalent opera-
tion.
During continuous operation, proper defrosting of the evapora-
tor must be guaranteed by maintaining a heating water return
temperature of more than 18 °C.
The heat pump is not designed for the increased heat con-
sumption required when a building is being dried out. For this
reason, the additional heat consumption should be met using
special devices provided by the customer. For drying out a
building in autumn or winter, it is advisable to install a second
heat generator (e.g. an electric heating element available as an
accessory).
NOTE
The device is not suitable for operation with a frequency
converter.

2.2 Operating principle

Heating
Surrounding air is drawn in by the fan and fed through the evap-
orator (heat exchanger). The evaporator cools the air, i.e. ex-
tracts heat from it. This extracted heat is then transferred to the
working medium (refrigerant) in the evaporator.
The heat is brought to a higher temperature level by increasing
its pressure with the aid of an electrically driven compressor. It
is then transferred to the heating water via the liquefier (heat
exchanger).
Electrical energy is used to raise the temperature of the heat
from the environment to a higher level. Because the energy ex-
tracted from the air is transferred to the heating water, this type
of device is referred to as an air-to-water heat pump.
The main components of an air-to-water heat pump are the
evaporator, fan and expansion valve, as well as the low-noise
compressor, liquefier and the electrical control system.
At low ambient temperatures, humidity accumulates on the
evaporator in the form of frost, reducing the transfer of heat.
Uneven accumulation during this process does not indicate a
fault. The evaporator is defrosted automatically by the heat
pump as required. Under certain atmospheric conditions,
steam may be emitted from the air outlet.
