NIBE™ VVM 325Chapter 3 | Indoor module's design8

General pipe connections
Pipe installation must be carried out in accordance with
current norms and directives.
VVM 325 together with air/water heat pumps F2030-
7/F2030-9 or F2040-8/F2040-12 make up a complete
installation for heating and hot water.
The system requires a low-temperature design of the
radiator circuit. At lowest dimensioned outdoor tem-
perature (DUT) the highest recommended temperat-
ures are 55 °C on the flow line and 45 °C on the return
line, but VVM 325 can handle up to 65 °C.
Overflow water from the safety valve goes via overflow
cups to a drain so that hot water splashes cannot cause
injury. The entire length of the overflow water pipe
must be inclined to prevent water pockets and must
also be frost proof.
NIBE recommends installing VVM 325 as close to the
heat pump as possible for optimum comfort. For further
information about the location of different compon-
ents, see section "Installation alternatives" in this
manual.
NOTE
Any high points in the climate system, must
be equipped with air vents.
NOTE
The pipe systems need to be flushed out be-
fore the indoor module is connected so that
any debris cannot damage component parts.
NOTE
Switch (SF1) must not be moved to "" or " "
until VVM 325 has been filled with water.
Otherwise the temperature limiter, thermostat
and the immersion heater etc can be dam-
aged.
Boiler and radiator volumes
H
VVM 325 is equipped with a
pressure expansion vessel of
10 Iitres.
The initial pressure of the
pressure expansion vessel
must be dimensioned accord-
ing to the maximum height
(H) between the vessel and
the highest positioned radiat-
or, see figure. An initial pres-
sure of 0.5 bar (5 mvp) means
a maximum permitted height
difference of 5 m.
The maximum system volume
excluding the boiler is 220
litres at the above pre-pres-
sure.
System diagram
VVM 325 consists of water heater with charge coil, ex-
pansion vessel, safety valve, filler valve, immersion
heater, circulation pumps, buffer vessel and control
system. VVM 325 is connected to the climate system.
VVM 325 is designed for connection and communica-
tion with F2030/F2040, which together make up a
complete heating installation.
When it is cold outdoors F2030/F2040 works with VVM
325 and if the outdoor air temperature falls below the
heat pump stop temperature, all heating is carried out
by VVM 325.

VVM 325 can be connected to extra water heater, see
below.
Further option information is available at www.nibe.eu
and in the respective assembly instructions for the ac-
cessories used. See page 69 for a list of the accessories
that can be used with VVM 325.
Extra hot water heaters
The indoor module can be supplemented with an
electric water heater, if a hot tub or other significant
consumer of hot water is installed. A mixing valve is
then installed on outgoing hot water from the heater.
Water heater with immersion heater
If it is possible to use a water heater with an immersion
heater, NIBE COMPACT or EMINENT type water heaters
can be used.
If the valve connector is to be installed externally,
moved out or separated, it must be replaced with a
separable connector Ø 22 mm.
