Beretta MYNUTE BOILER GREEN range complies with the European ErP
regulations, which came into force on 26.09.2015.
From that date onwards, a new energy labelling was implemented for
appliances and systems producing heating and domestic hot water and a
series of efficiency and emissions constraints automatically excluded the less
performing classes of appliances. The new ErP regulations aim to help the EU
countries to reach by 2020 the “20-20-20” target, meaning a 20% reduction
of gas emissions; a 20% increase in the use of renewable energies; a 20%
reduction in global energy consumptions.

Saving energy, saving money
The new energy labelling, that according to the ErP
directive was implemented in September 2015 for
appliances and systems producing heating and
domestic hot water, means that all boilers and heating
systems are labelled in the same way as “white
goods”, like washing machines and refrigerators.
The energy labelling enables the end-users to make
realistic comparisons among different products. By
choosing high efficiency products, the end-users
can lower their energy bills, helping to safeguard the
environment.

High performance through user-friendly controls
The MYNUTE BOILER GREEN control panel,
located under a hinged flap, is simple and
user-friendly. Two ergonomic knobs allow to
easily control all the boiler functions. The central
heating knob activates also the S.A.R.A.
function. The white backlight digital display
on the control panel provides the end-user
immediately with all information about the
boiler status. The system filling through the
practical filling tap can be easily checked
on the hydrometer on the control panel.

A cascade of hot water
MYNUTE BOILER GREEN can immediately
supply up to 141/183 litres DHW in 10
minutes (with ΔT = 30°C), thanks to the
built-in stainless steel tank with 45/60
litres capacity. The DHW tank is equipped
with a magnesium anode to offer protection
against stray currents and, thanks to
the wide flange, the tank can be easily
inspected. In order to save gas consumption,
a highly protective insulation of the tank
prevents water cooling, while minimizing
the burner ignitions (to recover the DHW
tank temperature). MYNUTE BOILER GREEN
features also the DHW expansion vessel and
is suitable for DHW recirculation (through
optional kit).

Highest reliability
MYNUTE BOILER GREEN is provided with
the most innovative safety devices: control
systems that check the flame presence, the
correct flue evacuation, the temperatures
and the pressures. Besides,
it features a circulation pump and a threeway valve with anti-blocking cycles that
ensure efficiency and operation: in case of
inactivity of the boiler components, being
the boiler installed and electrically fed, the
blocking of the components is avoided.
The boiler allows the climatic
thermoregulation, that can be activated
through the external probe (available as
option) for a high comfort inside the house;
besides it is suitable for connection with the
Beretta remote control panel (available as
option) for the control and check of the boiler
status from remote.

S.A.R.A. system: comfort and saving
MYNUTE BOILER GREEN models are
equipped with the Beretta patented S.A.R.A.
System (Automatic Temperature Control),
which can be enabled by moving the
temperature control knob of the central
heating circuit to the “AUTO” sector
(between 55°C and 65°C). The S.A.R.A
system achieves the best compromise
between the average temperature of the
radiators and the quickness in reaching the
required room temperature, while providing
energy and money saving.
When there is a demand for heating, the
appliance will automatically raise the heating
flow temperature twice, by 5°C every 20
minutes, in order to heat the home more
quickly. When the heating request has been
satisfied (see diagram), the appliance will
swich off automatically till the next heating
request. At that point the boiler will start
again at the previously set flow temperature.
Range Rated
Heating flow T
The term “Range Rated” identifies a product
homologated at different levels of heat input
and provided with a special feature allowing
to precisely adapt the maximum power of
the boiler to the thermal needs of the central
heating system.
With MYNUTE BOILER GREEN, Beretta offers
the possibility to set the power of your boiler
according to the real energy requests of the
building through a simple operation during
the installation. The fan revolutions number
(r.p.m.) will only have to be adjusted and the
new set power will be written on a label on
the boiler.
Thanks to the “Range Rated” certification,
MYNUTE BOILER GREEN operation can be
optimized, avoiding any gas waste and
reducing wear and tear on boiler
components.

Condensing heat-exchanger
The Beretta condensing heat exchanger is
manufactured in a single aluminium pipe,
without weldings.
The high thermal conductivity of the
aluminium allows a more uniform
temperature distribution so that no hot spots
are present: this translates in a longer life
span of the exchanger.
Moreover, the aluminium is very resistant
against the corrosion.
The single-pipe layout (in-series circuit)
offers a wide section for the water passage,
with the consequent advantage of having
low head losses while preventing the deposit
both of limescale and impurities.
Flue collector with flue
gas analisys and
condensate drain
The condensing heat-exchanger allows to
recover a large part of the latent heat of the
gas flues, reducing in this way much of the
heat losses.
