 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.
 The “heart” of the matter
A cast iron heat exchanger is at the heart of every
IQ 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 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 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.
