Operating principle of heat
pumps
Heat pumps operate on the same principle as a
refrigerator: same technology, only with reversed
benets. 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 conditioned
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
approx. 3/4= environmental energy
approx. 1⁄4= external electrical
energy
Area of utilisation
Taking into consideration the ambient conditions, limits
of application and the applicable regulations, every heat
pump can be utilised in new or existing heating systems.

Heat metering
In addition to proof of the unit’s efciency, the
EEWaermeG also requires heat metering (hereafter
referred to as HQR). Heat metering is mandatory for
air/water heat pumps. Heat metering for brine/water
and water/water heat pumps only have to be installed
for a ow temperature ≥ 35 °C. The heat metering must
record the total thermal energy released (heating and
domestic hot water) in the building. In heat pumps with
heat metering, the analysis is carried out by the regulator.
The regulator displays the thermal energy discharged in
the heating system in kWh.
Operation
Your decision to purchase a heat pump or a heat
pump system is a long-term contribution to protecting
the environment through low emissions and reduced
primary energy use.
To ensure that your heat pump or heat pump system
operates ef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 efciency of the system.
€ENERGY SAVING TIP
Preferably use purge ventilation. Compared to
continuously open windows, it is better to air
rooms by fully opening windows for a short
period, two to three times a day (so-called
“rapid” or “purge” ventilation); this reduces
energy consumption and your heating bill.
You can operate and control the heat pump system
with the control element of the heating and heat pump
regulator.
NOTE.
Make sure that the control settings are correct.
Operating manual of the heating and heat pump
regulator.
Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and standard cleaning products.
Do not use cleaning or care products that contain
abrasives, acids and/or chlorine. Such products would
destroy 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 regular
maintenance.
According to EU regulation (EC) 842/2006 of May 17,
2006, leak inspections and maintenance of a log book
are required 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 and cleaned
as needed - at the very least annually - by qualied
personnel (heating or cooling system tters).
It is best to arrange a maintenance agreement with a
heating installation company. The company will arrange
for the required maintenance at regular intervals.

of the buffer tank is calculated based on the following
formula:
VBuffer tank = minimum ow rate of heat circuit volume ow / hour
10
For the minimum ow rate of the heat circuit
volume ow, see overview “Technical data/
Scope of delivery”, “Heating circuit” section.
DOMESTIC WATER HEATING
The domestic water heating with the heat pump requires
an additional hot water circuit, parallel to the heating
circuit. When installing, make sure that the domestic hot
water charge is not fed through the buffer tank of the
heating circuit.
“Hydraulic connection” instructions.
DOMESTIC HOT WATER TANK
If the heat pump is to be used for domestic water
heating, you must integrate special domestic hot water
tanks in the heat pump system. Choose a storage volume
so that the required quantity of hot water is available
even during a power cut.
NOTE:
The heat exchanger surface of the domestic hot
water tank must be dimensioned so that the
heating capacity of the heat pump is transferred
with minimum spread.
We offer a variety of domestic hot water tanks for you
to choose from. They are optimised for use with your
heat pump.
