Running costs
5. Running costs
In the first two heating seasons, higher running costs are
to be expected (up to 50% more, depending on residual
moisture in the building).
5.1 Flow temperatures
For optimum operation of your heat pump, you should aim
for the lowest possible heating flow temperatures (and also
DHW temperatures). The maximum system temperature
for your heat pump should be restricted to max. 55°C.
Note
Increasing the room temperature by 1°C results in
an increase in consumption of 5-7%.
5.2 Ventilation
Impact ventilation should be carried out according to user
requirements, especially during the heating season. Impact
ventilation is considerably more energy efficient than per -
manent ventilation, and therefore saves money.
»
Avoid permanent ventilation.
5.3 Heating setback program
Note
From an energy efficiency point of view, using a
time program to reduce the heating flow temper -
ature is not recommended for low temperature
heating systems (such as underfloor heating), es -
pecially with air/water heat pumps. These systems
are slow to respond and, due to the additional sys-
tem output required after the end of the setback
phase, it is possible that the second heat generator
(boiler, electric immersion heater) will cut in. This
can lead to higher running costs.
6. Maintenance and care
Material damage
Maintenance work on electrical components of the
heat pump may only be carried out by qualified
contractors.
Note
In many places, national and regional regulations
stipulate an annual leakage test on the refrigerant
circuit.
»
Ensure that the refrigerant circuit of your heat
pump is tested for leaks once a year.
»
In doing so, observe all national and regional
rules and regulations (e.g. Regulation (EU)
No 517/2014, AS 2022 162 or SI 2021/543).
»
Ensure year-round access to the soldered
joints in the refrigerant circuit.
»
Ensure that the leakage tests carried out are
recorded in the service book provided.
WARNING
The following maintenance work may be carried
out only by OCHSNER Customer Service or by an
authorised OCHSNER Customer Service partner:
- Maintenance work not described in the section
on appliance maintenance
- Maintenance work on the refrigeration technol-
ogy
WARNING: Electrocution
For maintenance work, cut off the power supply to
the indoor and outdoor units of your heat pump.
WARNING
Never use a potential ignition source when search-
ing for leaks in the refrigerant circuit.
Caution: Sound emissions
When the casing is open, the running compressor
may cause increased sound emissions.

6.1 General
We recommend arranging for OCHSNER Customer Ser-
vice to inspect and if necessary service the heat pump
once a year. We draw your attention to the fact that statu-
tory regulations require the system user to regularly check
their heating system.
The refrigerants used in OCHSNER heat pumps are
non-flammable, non-toxic and ozone neutral. Heat pumps
are classed as refrigeration equipment and are subject to
national and regional rules and regulations (e.g. Regulation
(EU) No 517/2014 and SI 2021/543).
OCHSNER Customer Service will be pleased to help in
carrying out maintenance and testing, in particular as re-
quired by these regulations. You can find more information
at www.ochsner.com.
We recommend testing the heating water system pressure
and correcting it if necessary (pressure too high/low).
