Model C 1210 ES NG is the highest performance, fully condensing natural gas tankless water heater from Bosch. Unlike traditional non-condensing models, condensing technology captures heat from the exhaust gas and uses it to preheat the incoming cold water. This increases efficiency and reduces emissions - well ahead of the 2012 Low NOX emissions standards set by SCAQMD (California's South Coast Air Quality Management District). Perfect for residential or commercial applications, the unit offers a 12.1 gpm hot water capacity at 35 degree F rise and features electronic ignition and patented burner design.
