The Therm C 1050 ES tankless water heater has had an efficiency increase of 2 percent made to it; increasing its total energy factor (EF) to 0.94. Also, the C 1050 ES, along with three other Therm models — C 1210 ESC, C 1210 ES, and the new C 950 ES — meet the new, stricter, Low NOx requirement passed by utility regulatory agencies in California and Vermont. Therm units include a design using a wide flame pattern and secondary dilution air that results in a lower flame temperature during the heating process. According to the manufacturer, combined with condensing technology, which utilizes a secondary heat exchanger to capture more heat from the exhaust for preheating incoming cold water, these models offer an attractive tankless water heating option that meets future code requirements today while offering optimal efficiency. The Therm line features models with updated software that delivers performance-enhancing features including a minimum activation flow rate of 0.5 gallons per minute 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.
