Fig. 3.1 Filling level of the brine expansion tank
It is normal for the filling level of the brine to fall a little
in the first month after the start-up of the system. The
filling level can also vary depending on the temperature
of the heat source. However it should never sink so far
that it is no longer visible in the expansion tank.
a
Caution!
Danger of damage
The brine circuit of your heat pump sys-
tem must only be filled by authorised
technical personnel.
Check the filling level of the brine circuit
at regular intervals and inform your ex-
pert technician company if the filling
level in the brine expansion tank is too
low.
3.4.3 Accumulation of condensate (condensation
water)
The evaporator, the brine pumps and the pipes in the
heat source circuit, as well as some components in the
coolant circuit, are insulated in the interior of the heat
pump, so that no condensate can accumulate. If a small
amount of condensate does form, it falls into the con-
densate pan. The condensate pan is located on the in-
side, in the lower part of the heat pump. As a result of
the heat generated inside the heat pump, the conden-
sate in the condensate pan evaporates. Small amounts
of the accumulating condensate can be drained off
under the heat pump. In small amounts, accumulating
condensate should not be seen as a fault in the heat
pump.
3.5 Energy
saving
tips
Below you will find important tips to help you operate
your heat pump system in an energy and cost-saving
manner.
3.5.1
General energy saving tips
You can even save energy by your general behaviour:
— Ventilate correctly:
Do not leave windows or French windows tilted open,
but rather open the windows wide 3 or 4 times a day
for 15 minutes and turn down the thermostatic valves
or room thermostats while ventilating.
— Do not block the radiators to ensure that heated air
can circulate in the room.
— Use a ventilation system with heat recovery.
The optimum exchange of air in the building is always
guaranteed by the use of a ventilation system with
heat recovery (windows no longer need to be opened
for ventilation purposes). If necessary, the air flow can
be matched to your individual requirements with the
ventilation unit's remote control.
— Check that windows and doors are airtight: Keep shut-
ters and blinds closed at night, so that as little heat as
possible is lost.
— If a VR 90 remote control unit is installed as an acces-
sory, do not obstruct it with furniture, etc., so that it
can measure the circulating room air unhindered.
— Think when using water, for example, take a shower
instead of a bath, promptly renew the seals on drip-
ping taps.
3.5.2 Economising by the correct use of the
control system
Further economies can be made by the correct use of
the control system on your heat pump.
The heat pump control system helps you to make sav-
ings by:
— Correct selection of the heating flow temperature:
Your heat pump controls the heating flow tempera-
ture depending on the room temperature you have
set. Therefore select a room temperature that is just
sufficient for your comfort, for example 20 °C. Every
degree over and above that means an increase in en-
ergy consumption of around 6 % per annum.
