Product Overview

Did you know?
Our heat exchanger has a proven track record of over 20 years
in customer satisfaction with over 1.5 million boilers installed
and counting.
2-in-1 Heat Exchanger
A reliable coppertube/aluminum block
heat exchanger paired with an advanced
control that automatically regulates the capacity
of the boiler to maximize efficiency
without compromising comfort.
Easy Service and Maintenance
Unparalleled reliability through simplicity.
Since the Challenger contains fewer internal
parts, the unit is much easier to install,
maintain and service.
Fully Condensing (Combi)
Our combi unit condenses in both space
heating and domestic hot water modes,
resulting in higher efficiency.
Smaller Footprint
The Challenger was designed to fit into the
smallest of spaces. Taking up less than 3ft,
the Challenger can fit in a small storage
area or utility closet. But with an attractive
enclosure and whisper quiet operation,
why hide it at all?
