Bosch Thermotechnology North America now offers a condensing product line that meets new Ultra Low NOx requirements ahead of a mandated 2012 date for the marketplace.

Bosch Therm tankless models C 1210 ESC, C 1210 ES, C1050 ES and C 950 ES are currently the only condensing tankless product series on the market that meet the new, more strict NOx requirements passed by utility regulatory agencies in California and Vermont, the company says. Effective 2012, the new regulations require water-heating units to limit noxious gas displacement in the heating process to less than 14 ng of NOx per joule of energy consumed. The Bosch line meets this requirement, the company says.

The units use a unique design that produces a lower flame temperature from the burner, and a wide flame pattern versus a segmented burner assembly and diluted air used in the heating process, the company says. Combined with condensing technology, which captures exhaust gases to preheat incoming cold water, these models offer an attractive tankless water heating option that meets future code requirements today while offering optimal efficiency.

The complete Bosch Therm line features models with updated software that delivers performance-enhancing features including a minimum activation flow rate of 0.5 gallons per minute (GPM) and the ability on many models to cascade up-to-24 units for larger commercial applications. The Bosch Therm line includes Energy Star rated models, powered by natural gas or propane, which have an industry-best 15-year warranty.
