Bosch Therm Units meet low NOx - Gas Tankless Water Heaters
Bosch Thermotechnology North America, a leading provider of energy efficient water heaters, heating and air conditioning comfort systems as well as high quality solar thermal systems for commercial and residential use, announced today the following Therm tankless products from Bosch meet recently enacted Low emission (NOx) requirements passed by utility regulatory agencies in California and Vermont: Therm C 1210 ES/ESC; C 1050 ESC; 950 ES; 940 ES/ESO and 830 ES. All models offer NOx emissions of 14 ng/J or 20 ppm or less. California and Vermont are currently the first two states to enact the 14 ng/J or 20-ppm NOx level.
In accordance with the new guidelines as published in new Air Quality Management District (AQMD) ordinances, the following Bosch models will no longer be sold nor allowed for installation in areas that are subject to these AQMD ordinances: Therm 520 PN/HN; 330 PN, and 660 EF/EFO. AQMD’s are regulatory agencies supported by state government to help control and preserve air quality standards for a given area.
Therm units from Bosch include a unique design using a wide flame pattern and secondary dilution air that results in a lower flame temperature during the heating process. 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 complete Therm line from Bosch features models with updated software that delivers performance-enhancing characteristics 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 an industry best 15-year warranty.
HVAC & plumbing professionals and affected homeowners in California and Vermont are encouraged to check with local regulatory agencies to ensure compliance of all tankless units with the new low NOx requirements.
