How heat pumps work
Heat pumps operate on the same principle as a refrigerator:
the same technology, only with reversed benefits. The
refrigerator extracts heat from food, It discharges this heat
into the room through fins at its rear.
The heat pump extracts heat from our environment:
from the air, earth or groundwater. The extracted heat is
conditioned in the unit and passed on to the heating water.
Even when it is extremely cold outside, the heat pump
draws enough heat to heat a house.

Area of use
Taking into consideration the ambient conditions, limits of
use and the relevant regulations, any heat pump can be used
in new or existing heating systems.
“Technical data /scope of supply” overview.
Heat metering
In addition to proof of the unit's efficiency, the EEWaermeG
(German law promoting renewable energy for heating) also
requires heat metering (hereinafter referred to as WME).
Heat metering is mandatory for air/water heat pumps. Heat
metering for brine/water and water/water heat pumps only
has to be installed for a flow temperature ≥35 °C. The heat
metering must record the total thermal energy output
(heating and hot water) to the building. In heat pumps with
heat metering, the evaluation is carried out by the controller.
The controller displays the thermal energy output into 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.
You use the control element of the heating and heat pump
controller to operate and control the heat pump system.
NOTE.
Make sure that the controller settings are correct.

To ensure that your heat pump or heat pump system
operates efficiently and ecologically, please pay particular
attention to the following:
€
ENERGY SAVING TIP
Avoid unnecessarily high flow temperatures.
The lower the flow temperature on the heating
water side the more efficient the system.
€
ENERGY SAVING TIP
Preferably use purge ventilation. Compared to con-
tinuously open windows, it is better to air rooms
by fully opening windows for a short period, two
to three times a day (so-called “purge” ventilation);
this reduces energy consumption and your heating
bill.
