Nibe S2125 Manuel utilisateur

NIBE S2125 is an intelligent, inverter-controlled

air/water pump. With NIBE indoor modules, it forms

a very efficient climate system for your home. NIBE

S2125 provides optimised savings as it automatically

adapts to your home’s output requirements all year

around.

The NIBE S2125 has an optimised seasonal perform-

ance factor*, which results in low operating costs

and high-performance hot water. The working area

gives a supply temperature of up to 75°C. At an

outdoor temperature down towards –25°C, it still

delivers up to 65°C, while the noise level stays low.

Available in two power sizes, 8 and 12.

Together with the NIBE S-series indoor module with

built-in wifi connection and the possibility of wireless

accessories, the S-series is a natural part of your

connected home. Smart technology adjusts the in-

door climate automatically while you’re in complete

control from your phone or tablet. Giving high com-

fort and low energy consumption, while doing nature

a favour at the same time.

• Optimised seasonal performance factor* and low

operating costs.

• Working range up to 75°C supply temperature and

65°C at an outdoor temperature of –25°C.

• New design for low noise level.

*The NIBE S2125 has a rating of SCOP of 5.0 (Average climate,

35/55 °C) and SCOP of >4.1 (Cold climate, 35/55 °C) in accordance

with European standard EN 14825:2018, i.e. the standard for de-

termining the reference seasonal effect level, SCOP. Applies to

S2125 -8 and -12.

Installation method

S2125 – a part of your climate system where S2125 is

intended to be combined with one of the indoor modules

VVM or the control modules SMO.

Together with an indoor module, S2125 creates a com-

plete heating/cooling and hot water unit. Our flexible

indoor modules provide efficient heating and high hot

water performance. VVM indoor modules are complete

with a smart and user-friendly control system, hot water

heater, additional heat, self-regulating circulation pump,

etc.

The control modules, SMO, offer a flexible system

solution that can be easily customised. For systems

with SMO, different components such as water heaters,

additional heat and other accessories can be selected

to suit the installation’s requirements.

There is a wide range of system solutions and accessor-

ies for NIBE's indoor modules and control modules.

Transport

S2125 must be transported and stored vertically.

Ensure that the heat pump cannot fall over during

transport.

Check that the heat pump has not been damaged during

transport.

Installation and

positioning

• Place the heat pump in a suitable location outdoors

to prevent any risk of the refrigerant flowing in through

ventilation openings, doors or similar openings in the

event of a leak. It must also not constitute a hazard

to people or property in any other way.

• If the heat pump is placed in a location where any re-

frigerant leak could accumulate, for example below

ground level (in a dip or low-lying recess), the installa-

tion must satisfy the same requirements that apply

for gas detection and the ventilation of engineering

rooms. Requirements regarding sources of ignition

must be applied where appropriate.

• Place S2125 outdoors on a solid level base that can

take the weight, preferably a concrete foundation. If

concrete slabs are used they must rest on asphalt or

shingle.

• The lower edge of the evaporator must not be lower

than the level of the average local snow depth. The

base should be at least 70 mm tall.

•S2125 should not be positioned next to noise-sensitive

walls, for example, next to a bedroom.

• Also ensure that the placement does not inconveni-

ence the neighbours.

• S2125 must not be placed so that recirculation of the

outdoor air is possible. Recirculation entails reduced

power and impaired efficiency.

• The evaporator must be sheltered from direct wind / ,

which negatively affects the defrosting function. Place

S2125 protected from wind / against the evaporator.

•Small amounts of condensation water, as well as melt

water from defrosting, may be produced. Condensa-

tion water must be led off to a drain or equivalent.

• Care must be exercised so that the heat pump is not

scratched during installation.

Do not place S2125 directly on the lawn or other non

If there is a risk of snow slip from roof, a protective roof

or cover must be erected to protect the heat pump,

pipes and wiring.

LIFT FROM THE STREET TO THE SET UP

LOCATION

If the base allows, the simplest thing is to use a pallet

truck to move the S2125 to the set up location.

The centre of gravity is offset to one side (see print on

the packaging).

LEK

C:a 180 kg

Approx. 180 kg

If S2125 needs to be transported across soft ground,

such as a lawn, we recommend using a crane truck that

can lift it to the installation location. When S2125 is lifted

with a crane, the packaging must be untouched.

If a crane vehicle cannot be used the S2125 can be

transported on an extended sack truck. S2125 must be

taken from its heaviest side and two people are required

to lift S2125.

LIFT FROM THE PALLET TO FINAL

POSITIONING

Before lifting remove the packaging and the securing

strap to the pallet.

Place lifting straps around each machine foot. Lifting

from the pallet to the base requires four persons, one

for each lifting strap.

Supplied components

Local differences in the enclosed kit may occur. See

relevant installer manual for more information.

Installation area

The distance between S2125 and the house wall must

be at least 350 mm, but not more than 500 mm in loca-

tions that are exposed to the wind. The free space above

S2125 must be at least 1,000 mm. The free space in

front must be at least 1,000 mm for any future servicing.

Inspection of the

installation

Current regulations require the heating installation to be

inspected before it is commissioned. The inspection

must be carried out by a suitably qualified person and

should be documented. The above applies to closed

heating systems.

If the heat pump is replaced, the installation must be

inspected again.

Condensation water

trough

The condensate drain pan collects and leads away the

condensation water.

It is important for the heat pump’s function that the

condensation water is led away and that the outlet for

the condensation water pipe is positioned so as to pre-

vent damage to the building. Condensation run-off

should be checked regularly, especially during the au-

tumn. Clean if necessary.

Pipe with heating cable for draining the condensate drip

tray is not included. To ensure the function, the access-

ory KVR 11 should be used.

• The condensation water (up to 50 litres/24 hrs) that

collects in the trough should be routed away by a pipe

to an appropriate drain, it is recommended that the

shortest outdoor stretch possible is used.

• The section of the pipe that can be affected by frost

must be heated by the heating cable to prevent

freezing.

Pipe with heating cable for draining the condensation

water trough is not included.

To ensure the function, the accessory KVR 11 should

be used.

• Route the pipe downward from S2125.

• The outlet of the condensation water pipe must be at

a depth that is frost free or alternatively indoors (with

reservation for local ordinances and regulations).

• Use a water trap for installations where air circulation

may occur in the condensation water pipe.

• The insulation must seal against the bottom of the

condensation water trough.
