Top technology for top performance
The Vitocal 300-A is the first air/water heat
pump with digital scroll technology and an
electronic bi-flow expansion valve. This
means it achieves an extremely high
Coefficient of Performance of 3.5 (air 2 °C/
water 35 °C) and therefore high seasonal
performance factors too. What's more, it
accounts for the particularly reliable heat
supply of the Vitocal 300-A, as well as
providing significantly lower running costs.
RCD: Always as much heat as you need
RCD stands for Refrigerant Cycle Diagnostic
system. This is responsible for permanently
monitoring the heat demand and the output
made available by the Vitocal 300-A. It
uses this information to match the two and
can therefore achieve the highest level of
efficiency at every operating point.
Not only quiet at night
Particularly quiet operation is ensured by a
radial fan with variable speed control and a
reduced fan speed for night operation.
Everything you need
Every household has different heat demands
and the conditions for installing a heat pump
vary. The range of accessories for the Vitocal
300-A is suitably flexible and comprehensive.
Subject to demand, the heat pump can be
supplied fully equipped. This means the
heating circuit pump, expansion vessel and
safety equipment have already been fully
fitted. Even the modular electric instantaneous
heater can be easily integrated. In conclusion,
Viessmann has the complete product range to
meet the demands of any installation you
require – inside or out.
Monitor and control from wherever
you are
With the new control unit in the Vitocal 300-A,
you can simply connect your heat pump to the
Vitocom 100. This gives you the option of
conveniently operating your heating system
via your mobile phone if you wish.
Cooling – no problem
Thanks to its reversible operation, the
Vitocal 300-A can also be used for cooling.
Convectors or surface cooling systems with
a cooling capacity of up to 8.6 kW give you
the flexibility to make your living area even
more pleasant.

Vitocal 300-AHeat pumps
Vitocal 300-A is
certified in accordance
with the EHPA heat
pump quality seal and
NF-PAC.

You'll really appreciate the Vitocal 300 -A for its quiet
operation. This is achieved by a special radial fan with
variable speed control, and the reduced fan speed during
night operation.
Take advantage of these benefits
Reversible air/water heat pump for heating and cooling for installation
inside and outside
Variable output control from 3.0 to 8.6 kW
High COP value (COP = Coefficient of Performance) in accordance with EN 14511:
3.5 (air 2 °C/water 35 °C)
4.4 (air 7 °C/water 35 °C)
Maximum flow temperature: up to 60 °C
Low operating noise through radial fan and reduced fan speed during
night operation
Efficient defrosting through circuit reversal
Heat pump control unit for remote control and monitoring
Particularly quiet, outdoor silent version available
230 V single phase unit
Easy to operate Vitotronic 200 heat pump control
Technology that interacts perfectly – the RCD system, the
digital scroll technology and the electronic bi-flow expansion
valve guarantee the highest level of efficiency at every
operating point.

Ideal for modernisation
With the Vitocal 350-A air/water heat pump,
modernising is easy. The additional vapour
injection in the compression process (EVI
cycle) enables flow temperatures up to 65 °C.
That makes it an ideal choice where older
heating systems with radiators are installed.
The heat pump draws its energy from the
ambient air without needing to drill boreholes
for geothermal probes.
High DHW convenience
Subject to model type, a higher flow
temperature enables a water temperature of
up to 55°C inside the DHW cylinder. This allows
the Vitocal 350-A to deliver a particularly high
DHW convenience. The Vitocal 350-A
achieves the high flow temperature of 65 °C
even at outside temperatures of -10°C.
RCD guarantees efficient operation
RCD stands for Refrigerant Cycle Diagnostic
system. In the Vitocal 350-A, it is responsible
for permanently monitoring the refrigerant
circuit. This, in conjunction with the electronic
expansion valve (EEV) ensures the highest
efficiency at every operating point. Alongside
this, important operating parameters are
saved and called up, when required, for
diagnosis, optimisation, energy statements
and to calculate the seasonal efficiency.
Vitocal 350-A is tested
in accordance with
the EHPA heat pump
quality seal.

The Compliant scroll compressor will win you over with its
inner values of reliability, safety and quietness.
Take advantage of these benefits
400 V three phase air/water heat pump, mono-mode with a heating output of
10.6 to 18.5 kW for heating and DHW heating
