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).
