Unrivaled corrosion-resistance
Stainless steel offers unparalleled resistance
to corrosion and the additives used in heating
systems. The grade of steel used is highly
resistant to the acidity of the condensates,
even when traces of sulphur are present in
the natural gas or propane used.
High efficiency
Advanced design of the Prestige® gas flue
tubes ensures optimum heat exchange and
therefore energy conversion
The Prestige® achieves exceptional efficiency
that remains stable throughout its service life.
Reduced maintenance
The Prestige® heat exchanger is self-clean-
ing: the condensates flow along the flue
tubes and continuously clean any combustion
residues.
The boiler continues to operate at high ef-
ficiency and maintenance is limited to routine
annual service calls.
Optimum water volume for
more stable operation
A proportionally larger volume of water sur-
rounds the flue tubes in the Prestige® stain-
less steel heat exchanger compared to rival
designs. This larger volume of water stabilises
the boiler temperature and minimises any risk
of overheating.
At the core of the Prestige® is our
proven stainless steel heat
exchanger, developed and improved
after intensive research and field
experience. ACV is able to apply
know-how from the use of stain-
less steel for heating and hot-water
production applications gained from
over 85 years of manufacturing
experience.
Stainless steel heat exchanger and
advanced high modulation burner
ACV BG 2000-M
modulating (ratio
1:6) gas DuoNit
burner, compatible
with both natural
gas and propane:
Pre-mix air/gas
burner, safe and
silent in operation,
which restricts NOx
emissions to below
40 mg / kWh
Combustion gases
flow vertically into
the heat exchanger
flue tubes and con-
dense in the lower
section, drawing
off all of the energy
created by combus-
tion and giving the
Prestige its excep-
tionally high level of
efficiency.
