High Eciency and
Environmentally Friendly
As fuel costs soar, home heating
eciency is on the mind of virtually
every homeowner.
All Ultra boilers feature a high
AFUE eciency level. This is one of
the highest eciency levels in the
industry, and when the Ultra is used
in low temperature applications such
as radiant heating, it can achieve even
higher eciencies.
The Ultra boiler is designed to
be environmentally friendly and
exceeds the highest North American
environmental air-quality standards.
In fact, it provides cleaner combustion
for low NOx applications allowing for
a reduction in green house gases.
While fuel eciency and the
environment are highly important
factors, here's another-the Ultra
system comes from Weil-McLain,
America's acknowledged leader in
boiler quality and reliability.
For well over a century, Weil-McLain
has been single-minded in its pursuit
of continual breakthrough innovation,
backed by a solid commitment to
provide the best customer service
and support.
The innovative Ultra Series 4, coupled
with the industry's greatest reputation
for quality, provides todays most
comforting combination.
How high heating costs fall to Ultra
technology
For gas fi
red appliances, Ultra
boilers employ an advanced
mono-block aluminum heat exchanger
that transfers heat faster than
conventional materials.
Ultra's unique electronic sensor and
control system allows key functions
like the modulation of firing rates up
or down, as conditions both inside and
outside the home fluctuate.
Unlike most other systems that
merely turn o or on at a single preset
indoor temperature, Ultra senses
precisely how much heat needs to be
produced at any given instant and
adjusts itself accordingly.
The result? Far greater fuel
eciency and far less wear and
tear on critical parts.
