EXTENDED
A great boiler, and an even better value!
The new X-2 boiler is designed to provide reliable, efficient heat
and to exceed the expectation of what a value-priced boiler
should be. Equipped with the same cast iron heat exchanger
as the IQ Series gas boilers, it provides comparible efficiencies
(84% AFUE). The X-2 isn’t a stripped-down boiler…far from it
actually. It comes equipped with many standard features found
on more expensive boilers. Equipment, such as a Low Water Cut-
Off safety device can be built into the X-2 at the factory, saving
time and money over having your heating contractor install it as
an add-on later.
The “heart” of the matter
A cast iron heat exchanger is at the heart of every X-2 boiler.
Crafted at a foundry in Zanesville, Ohio it is
comprised of 100% recycled material and designed
for years of reliable home comfort. Each cast iron
heat exchanger is water and pressure tested prior to assembly
in the finished boiler.
Built to last, made in America
When it comes to home heating, every BTU is precious. U.S.
Boiler Company understands, and takes energy efficiency
seriously. From thick insulated plates and seamless corners in
the burner base to the insulated steel jacket, the X-2 is designed
to keep heat where it belongs…in the heating system. The
boilers themselves are built in Lancaster, PA. Every component
is subject to strict standards of quality control and performance
verification used throughout the manufacturing process.
You’re covered…
A limited lifetime heat exchanger warranty,
plus a one-year manufacturer’s parts
warranty are included. For long-term
protection, the U.S. Boiler
Extended Warranty Plan is
also available. It offers parts
and labor protection for either
5 or 10 years from the date of
installation.
