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.

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, eliminating a separate heat exchanger and three-way valve.
