ABH Gas Fired Water Heaters are provided as complete rack mounted 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 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 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.
