Product description

Bosch C1210ESC Tankless Water HeaterThe Bosch C 1210 ESC Condensing tankless water heater is the highest performance, fully condensing gas tankless water heater from Bosch. This 225,000 BTU heater is designed for commerical applications and can deliver hot water up to 180 degrees F with a 12.1 GPM flow rate.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 -- South Coast Air Quality Management District).This heater features an electronic ignition system and can vent through either 3 inch or 4 inch diameter PVC vent pipe either through the side wall or up through the roof. A concentric venting option is available.This heater comes with built-in freeze protection and a water filter that is externally accessible, but does not come with a PRV.The Bosch Therm C1210 ESC is the direct replacement for the Bosch GWH C 920 ESC.

  • ASME certified
  • Up to 98% thermal efficiency
  • 225,000 BTU maximum input
  • 12.1 gallons per minute capacity at 35F degree rise
