Bosch Greentherm C 1050 ES LP 10.5 GPM 199000 BTU Condensing Propane Gas
Condensing tankless water heater is a top performance, fully condensing gas tankless water heater from Bosch. This 199,000 BTU heater is designed for residential applications and can deliver hot water up to 140 degrees F with a 10.5 GPM flow rate.
This Energy Star approved tankless water heater qualifies for the 2013 Federal Tax Credit and can produce enough hot water for 2-3 major applications in most homes.
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. Two concentric venting options are available including a polypropylene concentric up-and-out side-wall venting option for single units. Two to four units can now be exhausted through a single 6" polypropylene vent pipe.
The Bosch Greentherm model C 1050 ES has an Energy Factor up to 0.94 and is equipped with an automated and fully modulating bypass for unsurpassed DHW temperature stability.
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 Greentherm C1050ES is the direct replacement for the Bosch Therm C1050ES and the Bosch GWH C 800 ES.
