4 Energy-saving boiler
This boiler handles all the functionalities that one may expect of a
condensing boiler. Cutting edge technologies have been used not
only in its exceptionally economic design in terms of finance and
energy, and therefore also of environmental protection, but have also
been applied to provide maximum comfort: heating for the whole
house, hot water, incredibly simple to use and trouble-free operation
thanks to its reduced noise level.
The floor-standing gas condensing boiler is not content with using the
heat contained in the exhaust gases (perceptible) but also takes
advantage of latent heat (hidden). This energy is extracted from the
steam produced during the combustion process and is not exploited
by conventional boilers. The exhaust gases are here cooled in the
boiler in such a way that the steam condenses and the additional heat
from the exhaust gases is introduced into the heating system. A
special algorithm (Active Condens System) optimises the flow and
return temperature to the boiler during the tank loading phase, thanks
to a modulation of the circulating pump activated by rotation. The
boiler's efficiency is thus always optimum and the drinking water
draw-off capacity is increased.
The boiler meets the requirements of the German Decree on energy
savings (Energie-EinsparVerordnung, EnEV) and offers truly
exceptional value for money.
