 The best boiler for most homes
No matter how efficient a boiler is, if it doesn’t
operate efficiently in a home’s heating system,
it’s not an efficient installation. IQ gas boilers are
designed to handle the high water-volume systems
which are present in most homes. They have also
been designed to operate at lower
temperatures than conventional cast
iron gas boilers. This means that the
boiler doesn’t need to fire at a high
rate to maintain home heating comfort,
which translates into greater system efficiency and
lower heating bills.
 Built to save, 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, every IQ boiler is
designed from the ground up to keep heat in the
heating system.
The cast iron heat exchanger is the heart of these
boilers. It is manufactured in Zanesville, Ohio
and is designed for years of reliable service. Each
heat exchanger is water and pressure tested prior
to assembly. The boilers themselves are built in
Lancaster, PA. Every component used in the IQ
family of boilers is subject to strict standards of
quality control and performance verification which
are used throughout the manufacturing process.
