Triangle Tube is best known for two things: feats of hydronic innovation and incredibly efficient products. The Challenger Combi Boiler brings tankless water heating to the compact, high-efficiency Challenger series of boilers. Triangle Tube retained the low NOx, low noise design of the original Challenger and added on board domestic hot water production for even greater value. The condensing technology behind Challenger Combi boilers will capture and reuse gaseous heat that escapes traditional boilers. A unique cast-aluminum heat exchanger with copper waterways is the heart of the Challenger Combi. This blend of materials provides efficient heating and exceptional durability. Vertical flueways mean that you'll enjoy those benefits in a compact design. Indeed, the Challenger Solo has incredibly low profile and mounts conveniently on your wall. The Challenger is perfect for closet installations or just saving space in traditional installations, and it includes a bracket to simplify piping wherever you install it. If you have three cubic feet of space, you have room for heating for your home and domestic water supply. The ease-of-installation means that there is more reason than ever to add a high-efficiency Challenger Combi boiler to your system.
Intelligent DHW Control
The Challenger Combi can be set in ECO-mode. In this mode, it will learn what times of day have the highest hot water demands. The Combi will then maintain a minimum heat exchanger temperature at those times for instantaneous hot water even at high volume times.
Outdoor Reset Control
All Challenger Combi boilers include an outdoor reset sensor and outdoor reset control. This allows your boiler to regulate the temperature of your home based on the temperature outdoors which saves energy without sacrificing comfort.
Precision Through Sensors
The outdoor temperature is not the only temperature monitored by the Challenger. Sensors at the boiler supply and return also measure temperature and relay that information to your boiler so it can further refine its output and guarantee comfort and efficiency.
The Challenger can make fine adjustments to heating output because of its modulating burner. This burner allows minute, incremental changes in heat production to guarantee that you aren't using more energy than you need to be.
Dual Purpose Waterways
With a Challenger Combi, your domestic hot water is heated directly in the waterways of the heat exchanger. This eliminates the need for a secondary heat exchanger and additional equipment that is typical in other combination boilers. This also guarantees the full benefit of the condensing technology is applied to your DHW production.
The CC 125 is a sealed combustion hot water boiler and it vents conveniently through your wall. Challenger Solo boilers support concentric venting which reduces the number of vent pipes from two to one and further reduces the space necessary to install a Challenger.
