Operating principle of heat
pumps
Heat pumps operate on the principle of a refrigerator:
the same technology, only with the opposite effect. The
refrigerator extracts heat from foods, which is released
into the room through fins on the back.
The heat pump extracts heat from our environment: air,
earth or 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.

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.
Overview “Technical data / scope of delivery”.
Heat quantity recording
In addition to verification of the unit's efficiency,
EEWaermeG also meets the demand for a heat quantity
recording (hereafter referred to as HQR). The HQR
is mandatory with air/water heat pumps. With brine/
water and water/water heat pumps, an HQR may only
be set up when a forward flow 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.
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 with
the control element of the heating and heat pump regu-
lator.
NOTICE
Make sure that the control settings are correct.

To ensure that your heat pump or heat pump system op-
erates efficiently and ecologically, the following are espe-
cially important:
€
ENERGY SAVING TIP
Avoid unnecessarily high flow temperatures.
The lower the flow temperature on the hot wa-
ter side, the more efficient the system.
€
ENERGY SAVING TIP
Do not leave windows open continuously;
ventilate by opening windows wide for a
short time as this saves energy and reduc‑
es your heating costs.
