The Modena HE range
sets a new standard
for the domestic boiler
market. It is the smallest,
lightest and quietest
boiler in its class and
comes with a choice of a
5 or 2 year full parts and
labour manufacturer’s
warranty*.
NOx Class 5+ and
SEDBUK A ratings
demonstrate the
Modena’s outstanding
energy efficiency
standards to provide
what every customer
wants – an exceptionally
reliable boiler that
combines high
performance with
lower fuel bills.
At just 600mm high
the Modena can be
sited in the most
awkward of spaces; a
liftweight of between
28kg and 31.5kg allows
for one-man installation
and an operating noise
level of less than
40dB means it can
hardly be heard.

Essential to the boiler’s operation is the
availability of fresh, clean air and the ability
to dispose of combustion products. This is
achieved through the installation of a flue
which provides ducts to the outside of the
premises.
To optimise safety and performance, Ferroli
flues must always be used with Ferroli
boilers. Ferroli has a comprehensive range
of accessories to suit complex installations
and to enable the extension of flue lengths.

Condensing terminal positions: if the flue is to
be terminated at low level then the potential
effect of the plume must be considered.
The plume should not be directed:
– across a frequently used access route
– towards a window
– across a neighbouring property

Install energy efficient appliances
and products throughout the home
Homeowners will save money on fuel bills
when replacing older boilers with a new high
efficiency condensing appliance because new
boilers adjust automatically to ensure optimum
efficiency from the energy being used.
Choose the right type of boiler for
the size of the property
For larger homes, open vent or system boilers
combined with storage cylinders are one of the
most cost-effective ways of producing a larger
amount of domestic hot water. Combi boilers,
on the other hand, provide a highly efficient and
effective solution for smaller households as they
only heat water on demand, meaning energy
is not wasted on heating water that is surplus
to requirements. A correctly sized system is
always important for energy efficiency. A system
should be able to suit the needs of a household
without the need for regular overrides of the
programmed timings.
Heating homes and hot water efficiently, cost
effectively and in a sustainable way is high
on everyone’s agenda in the current climate.
Choosing the right products is a good start
but it is also about the way we use the
energy we generate and, more importantly,
the way we retain it.
