Meeting the ultra low NOx requirements of California and Vermont, Therm models C 1210 ESC, C 1210 ES, C 1050 ES, and C 950 ES are condensing tankless water heaters. According to the manufacturer, 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. 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, says the company. The complete 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 Therm line includes Energy Star®-rated models, powered by natural gas or propane, which have a 15-year warranty.
