ABH XL Gas Fired Water Heaters are provided as complete packaged water heating solutions inclusive of The Brain® Digital Recirculation Valve (DRV) for hot water system water temperature control. ABH assemblies are designed and built to meet the exact requirements of the installation site; all systems are shipped ready to set in place with minimal assembly.
ABH XL deploys a multiple pass condensing technology so that energy and heat from the combustion process is fully optimized by the unit’s heat exchanger. This innovative design maximizes the condensing condition across a broader operational range than traditional water heating technologies to deliver operating efficiencies as high as 99.8%.
ABH XL combustion efficiency is maximized by a unique, patented cold-water injection system (CWIS) in the storage tank ensures that the cold or system return water entering the heat exchanger is at the lowest possible temperature.
