Technical Data
The Ferroli Econcept 51A has been designed for high efficiencies
and very low emissions. The boiler has achieved 4 star efficiency
(EU Directive 92/42 EEC) and Class 5 for NOx
emissions (EU Directive EN 297/A5).
The Econcept 51A is equipped with Ferroli’s
patented premix ceramic reverse micro flame
burner. This burner is the key to the low
emissions and is designed to eliminate the effects of thermal
expansion of the burners.
The high efficiency heat exchanger is manufactured with 16mm
water ways to eliminate debris-related
corrosion and hot spots. The material
chosen for construction is aluminium silica
alloy which has been specifically formulated
for condensing boiler applications.
A key feature of the Econcept 51A is the inbuilt boiler pump and
the provision for an optional inbuilt DHW pump. The DHW control
is performed by the on-board controller (see page 4).

The ENERGY TOP W series boilers are wall-hung heat generators for
inside or outside installation, central heating only, featuring a premix
burner, condensing operation with very high efficiency and very low
polluting emissions. They consequently ensure high energy savings
and are environmentally-friendly (4 star energy rating according to
Directive 92/42 EEC, Class 5 emissions according to EN 297/A5).
Wall-hung structure with removable jacket split in 3 sections, for easy
access to the inner components. Possible installation as standard
outdoor in partially protected places, with temperatures untill to
-5°C, without using the additional frost protection kit. The cascaded
connection of multiple generators can be carried out using dedicated
cascade flues and hydraulic collective manifold.
The appliances are factory configured for operation on natural gas and
can be converted to LPG using the appropriate conversion kit available
upon demand.

The Ferroli Energy Top has been designed for high efficiencies
and very low emissions. The boiler has achieved 4 star efficiency
(EU Directive 92/42 EEC) and Class 5 for NOx emissions (EU
Directive EN 297/A5).
The Energy Top range is equipped with an
air/gas premix metal fibre burner complete
with variable speed fan. This burner is the
key to the low emissions and is designed to
eliminate the effects of thermal expansion.
The high efficiency heat exchanger is
manufactured with 31mm water ways to eliminate debris-related
corrosion and hot spots. The material chosen
for construction is aluminium silica alloy
which has been specifically formulated for
condensing boiler applications. The design
of the heat exchanger allows for a maximum
temperature difference across the flow and
return of 40ºC.
The range consists of two models, Energy
Top W80 and Energy Top W125.
