EOLO Extra kW HP
Wall-hung condensing boiler designed for high temperature systems
The continuous investment of Immergas in projecting and
manufacturing domestic use gas boilers, the constant research for
low environmental impact solutions and the always new requests
from the market’s side, gave birth to EOLO Extra kW HP boilers.
HP range boilers distinguish for the ability to achieve high efficiency
and respond to the installation requirements of new construction
buildings. In particular, they satisfy the specific exigencies of high
temperature heating systems, still being able to benefit from
condensing boilers combustion efficiency.
HIGH EFFICIENCY AND LOW CONSUMPTIONS
The technology characterizing EOLO Extra kW HP boilers allows
to accomplish the best comfort optimizing the efficiency and
reducing gas consumption to the minimum. Thanks to a special
combustion system, compared to traditional appliances, HP range
boilers greatly exploit the combustion generated heat with great
advantages in terms of performances. The nominal outputs of
24 and 30 kW fully suit the home wellness and sanitary comfort
necessities of the most demanding users.
EASY INSTALLATION
The compact dimensions of EOLO Extra kW HP
boilers consent to easily install them in your home,
even inside the kitchen cupboards, or to locate
them outdoor in a protected place, for example
under a balcony. The boiler installation features a
simple connection to the condensate drain (e.g. to
the kitchen sink siphon), while the use of the proper
plastic flue system allows for an easy evacuation of
the combustion products in any installation situation
(roof, wall or relined chimneys).
REMOTE THERMOREGULATION:
A COMFORT CHOICE
The appliance can be remotely controlled using the
CAR remote control (as option), allowing a better
climatic regulation of the room temperatures. In fact,
it substitutes the boiler control board carrying out
all its functions. This last aspect results particularly
useful when the boiler is installed outdoor, allowing
to manage the appliance staying comfortably inside
your home. HP boilers can be also combined with
other Immergas thermoregulation range devices.

MORE ENERGY WITH THE HEAT
RECUPERATOR
Peculiar characteristic of EOLO Extra kW HP boilers is the
use of a special heat recuperator positioned at the bottom
of the combustion chamber; this solution allows to transfer
further energy to the system, otherwise dispersed by the
combustion products.
The combustion products heat is given to the system
through a copper primary exchanger. The return circuit gets
preheated by the outlet flues, inside the heat recuperator.
The condensate deriving from it is evacuated by the proper
boiler siphon, without interesting the primary exchanger. All
EOLO Extra kW HP boilers must be installed in high
temperature systems with heating bodies such as
radiators or air convectors.

GUARANTEED SANITARY COMFORT
The sanitary hot water production makes use of an accurately
dimensioned heat exchanger to optimize performances over
time. EOLO Extra kW HP boilers are equipped with a 16
plate heat exchanger for the 24 kW model and with a 22
plate one for the 30 kW model.
OUTDOOR APPROVED
The IPX5D electric protection, along with the
possibility to install a -15 °C anti freeze protection
kit, make HP range boilers suitable for outdoor
installation in a partially protected place.

EOLO Extra kW HP boilers can be combined to the 5 typologies
of Immergas DIM (Multisystem Distribution Manifolds).
During the life of a boiler, performance is influenced by external factors, e.g. water hardness, atmospheric agents, system limiting, etc. The published
data refers to new products correctly installed and used, in accordance with local regulations. N.B. We recommend regular periodic maintenance of the
appliance.
