High Efficiency Space Heating and Domestic Hot Water in a Compact Package
The Challenger Combination Boiler features a unique “Two in One” heat exchanger that provides both space heating and domestic hot water. The Challenger Combination Boiler is designed to fit the needs of today’s energy efficient homes with inputs of 85, 105, and 125 MBH. The Challenger is not only energy efficient with an AFUE of 94%, but space efficient as well.

As a combination boiler, the Challenger eliminates the need for a separate domestic hot water tank. The unique heat exchanger in the Challenger heats domestic hot water directly, allowing the boiler to condense in the DHW mode and eliminating a separate heat exchanger and three-way valve.
