Viessmann heating equipment: Committed to the environment
Condensing technology offers the greatest potential for conserving fossil fuels in the heating sector.
A crucial element of the EC Directive
regarding "integrated pollution prevention and
control" (IPPC Directive) of 30th October 1996
is the stipulation to apply the "best available
technology" (BAT) in all new systems, and
since 2007, also in all existing systems.
Viessmann feels a traditional obligation to
the basic requirement of using the best
technology available while aiming to protect
the environment to the best of its ability.
As the generation of heating energy
accounts for 40 percent of all European
energy consumption, the best technology
available for this has a significant influence on
resources and environmental protection.
The following examples reflect this:
Condensing technology offers the
greatest energy utilisation
Condensing technology for oil and gas
currently offers the highest energy utilisation
with seasonal efficiencies (to DIN) of up to
98 percent. Compared to other technologies
for generating heat, this substantially reduces
the consumption of fossil fuels. In this
process, additional heat is obtained from the
flue gas through condensation. This makes
particularly high demands of the heating
surface material and design. All Viessmann
condensing boilers for gas or oil are therefore
equipped with stainless steel heating
surfaces/heat exchangers.
Fossil oil and gas may only be available for a
limited time now, but Viessmann condensing
technology is futureproof, because bio-oil and
biogas from sustainable materials can
gradually replace crude oil and natural gas.
Today, all Viessmann condensing boilers are
already prepared for admixtures of bio-oil
and biogas.
Weather Compensation – Great for gas bills
With the increasing cost of fuel, boiler
efficiency is becoming more and more
important. The only way to improve the
efficiency of a good quality condensing boiler
is to add weather compensation controls.
The Vitodens 100-W range are designed to
work with optional weather compensation
controls, to achieve additional fuel savings
of up to 12% – meaning huge savings every
year, for a small initial outlay (System models
must be installed as a 4-pipe system).
The controls work by monitoring the outside
air temperature and adjusting the heating
water from the boiler to suit. Lower flow and
return temperatures mean that the boiler can
condense more. This proactive mechanism
means that the boiler burns as much fuel as it
needs – but no more – to achieve the desired
room temperature.
People inside the building will experience a
constant temperature and won't even notice
that the temperature outside has changed –
but they will notice a significant reduction of
their gas bills!
Good news for architects and specifiers –
the weather compensation feature adds 3%
to the boiler's SEDBUK efficiency when using
SAP (Standard Assessmant Procedure).
