CIAO X ,

THE COMFORT
YOU DESERVE.

CIAO, ONE OF THE BEST-SELLING
WALL-HUNG BOILERS IN THE BERETTA
PORTFOLIO EVER, HAS NOW BEEN
COMPLETELY REDESIGNED, RESULTING IN
A NEW CONDENSING RANGE WITH MANY
INNOVATIVE FEATURES AND ADVANTAGES:
CIAO X

The new Beretta range retains the distinguishing

features of its predecessor in terms of reliability
and user-friendliness, while adding many
important and innovative ones: from the new

primar y heat-exchanger in stainless steel, to the
new touchpad interface up to the hydraulic DIN
connections.

With CIAO X Beretta enhances the research of
higher comfort and innovation in the respect of
the environment, which has always represented
one of the assets of the brand, since its origins.

This renewed energy consciousness translates

into high efficiency, low consumption and a high
modulation ratio (1:8), that combined with the
flexibility of installation, compact size and low
weight, allow to place CIAO X at the top of its
category.

But what’s more, CIAO X thinks ahead for future
generations. The new range can already process
a mixture of hydrogen up to 20%, the sustainable
energy source that will be the real ecological
turning point in the coming years.

THE RANGE

Ciao X comes in a complete range of 5 models, to satisfy all heating requirements:

• CIAO X 25 C (combi models, with dedicated codes for natural gas and LPG)

• CIAO X 30 C (combi model)

• CIAO X 15 R (heating only model)

• CIAO X 25 R (heating only model)

The compact size and low weight of CIAO X, allow it to be installed anywhere in the house,

even in a kitchen cupboard. The product is also suitable for recessed installation in a box or
for outdoor installation in partially protected places.

CONTROL YOUR
COMFORT BY
A TOUCH

One of the main distinguishing characteristics of the new

CIAO X is the digital touchpad interface, combining

innovative design and features with user-friendliness.

By a simple touch on 7 points of the panel, it is possible to

access in an intuitive way all the settings and parameters of

the boiler and the system.

Each touch activates a buzzer, that generates an acoustic

feedback as a confirmation of the operation.

The LCD display communicates with the user and installer

through icons, without using texts, so as to allow an

immediate understanding of the displayed function.

EVERYWHERE CIAO X

CIAO X features a modern and linear design, which

blends easily into any setting.

The compact dimensions and low weight allow the

product to be easily installed anywhere, not only inside

the house, but also recessed in box or outdoors, in a

partially protected space. CIAO X is therefore also ideal

for the replacement of old boilers, both with DIN or with

TECHNOLOGY AND
ENERGY-SAVING
HAND-IN-HAND

NEW CONDENSING HEAT
E X C H A N G E R

CIAO X features a high efficiency condensing heat exchanger in

stainless steel, compact and robust. It is made of a coiled smooth tube

with a large section, ensuring optimized efficiency of the combustion

and cleanness over time. The stainless-steel quality provides high

resistance to corrosion, deriving from acid condensate. The large

section of the tube and its geometry as a unique coil ensure a constant

flow and prevent intrinsically from clogging. The frontal access to heat

exchanger enables ease of maintenance and cleaning of the combustion

chamber.

NEW FUNCTIONS
FOR A HIGHER DHW COMFORT

In the combi models, the high-performance plate heat exchanger,

developed by Beretta, connected to the primary circuit of the hot water,

allows to warm up the DHW in an instantaneous way, without the need

of any external tank.

The new optimized heat-exchanger has been conceived to obtain the

best performance and maximum comfort for the end-user in terms

of temperature stability and reduced waiting times. These pluses,

which place the product at the top of its category, translate finally into

respect for the environment, saving water and energy.

PRE-HEATING AND ITS EVOLUTION INTO SMART PRE-HEATING

have been conceived in order to further save water and gas

consumption. They allow, in fact, to keep warm the water inside the

new high efficiency plate heat exchanger, produced in our plants, to

reduce waiting time.

This feature makes CIAO X ideal for installation indoor, even for

replacement in a kitchen.

A GREEN FUTURE
STARTING TODAY

CIAO X is born now, thinking of tomorrow. The new

condensing range, in fact, is designed to operate with

mixtures of natural gas and hydrogen - up to 20% - in

line with the environmental sustainability objectives and the

decarbonisation process started by the European Union.

HYDROGEN, THE SUSTAINABLE ENERGY
SOURCE OF THE FUTURE

THE CYCLE OF HYDROGEN USE

Hydrogen is a safe and clean gas, available in huge

quantities in nature. Mixed with natural gas up to a ratio

of 20 to 80%, hydrogen allows to generate heat and hot

water, helping to minimise polluting emissions. From the

combustion of oxygen and hydrogen, and in the amount

of the latter, water vapour is generated: in this way

hydrogen turns back to water, its most common source,

and reintroduced into nature.

WITH CIAO X FOR A HEALTHY LIVING

Beretta, always engaged in designing solutions

for heating and DHW comfort in the respect of the

environment, enhances with CIAO X the research of

efficiency in the conscious use of energy sources and

water. The new range is the result of the development of

innovative technologies and functions that allow energy

saving, to ensure a “green” comfort.

CIAO X modern technology and the possibility to

remotely control it by the end-user imply a benefit for the

environment that translates into cost savings for the

user.
