ASCEND^® On-Demand Gas Fired Water Heaters are provided as complete packaged water heating solution with The Brain^® Digital Recirculation Valve (DRV) “on-board” for hot water system water temperature control.

With the DRV on board, ASCEND^® on-demand water heaters provide the world’s first fully integrated, single footprint, tankless hot water generation and water temperature control solution compliant with ASSE 1017.

The on-board BRAIN^® delivers precise temperature control while ensuring water that reaches the heater is brought above legionella survival temperatures.

The ASCEND^® 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%.
