TANKLESS REPORT
Tankless is more: Exploring the benefits
P
hc News offers its tankless report, a compilation of information from the major tankless manufacturers in the industry. Tankless’ growth — even in this market — can be attributed to
many factors, “While the federal tax credit incentives have been reduced drastically from previous levels, there are still a number of factors that are positively affecting growth. Local utility rebates, increased interest in energy efficiency and more efficient product development all contribute to the current growth rate,” said David Chisolm, A. O. Smith brand manager. The manufacturers appear in no particular order. ;

Company History: Noritz America was established in California in 2002. Today, Noritz has corporate offices in five U.S. locations: Fountain Valley, Calif.; Dallas; Marietta, Ga.; Hawthorne, N.Y.; and Elk Grove Village, Ill. All five sites include showroom, training and technical- support facilities. In 2010, the facility in Marietta (Atlanta) underwent an expansion to include a showroom. Company News: The tankless
market is continuing the trend towards higher-efficiency, PVC- vented, condensing water heaters. Condensing tankless water heaters
Company History: Navien America, Inc., is a technology innovator of the condensing tankless gas water heater offering the highest efficiency on the market. The company was established to open new markets in the United States and Canada for parent company KD Navien. Navien America takes pride in providing high-quality and innovative products that are environmentally friendly, energy efficient, and offer high-tech comfort and convenience to its customers — products it describes as “the ultimate in energy efficiency with high-tech comfort.” Navien America is an official ENERGY STAR® partner of the Residential Water Heater Program. Company News: Navien America, Inc.’s ultra-condensing
All Navien units include a free intelligent remote control system to easily operate its systems.
Offering a maximum input of 180,000 Btu per hour and using state-of- the-art condensing technology, the NRC98 has an Energy Factor of approximately 0.93, or nearly 10 points higher than that of a comparable,
use a secondary heat exchanger to boost efficiency by capturing more heat from combustion gases as they escape up the flue. This heat-absorption process, in turn, cools these gases enough to permit venting with less costly, more installer-friendly PVC piping, rather than Category III Stainless Steel. Greater energy savings have played an important, but still
conventional tankless model and over 30 points more than the EF for a standard gas-fired storage water heater. Available late spring, the NRC98 will be ENERGY STAR®-qualified.
tankless gas water heater models offer the highest thermal efficiency ratings in the industry. Sales of company’s tankless gas water heaters and combination gas boiler/water heater units have tripled in the United States in the past several years alongside the expansion of Navien America into a new 130,000- square-foot corporate office and training facility in Irvine, Calif. In addition to the corporate location they also opened a new training facility and showroom in Cherry Hill, N.J. Tankless Forecast: The tankless water heater market
continues to expand rapidly. The tankless market is approaching one million units a year; this is against a back drop of about total market of eight million water heaters sold yearly in the Unites States. The tankless water heater market keeps taking share from the tank market because tankless water heaters make greater economic sense.

secondary role in the rising profile of condensing tankless water heaters, which offer efficiency gains of approximately 10 to 15 percentage points over conventional units — from percentages in the low to mid-’80s to around 95%. Like their conventional counterparts, all condensing units carry the ENERGY STAR label. Tankless Forecast: Studies show that water heating can
account for up to 25% of the energy consumed in a home. Choosing a tankless water heater can drastically reduce this large piece of the household energy pie, while saving space and meeting all of a household’s hot water needs. Tankless FAQ: Can I use the existing gas service when
replacing a tank water heater with a tankless unit? No, not generally. The energy savings found with tankless
heaters is due to the on-demand technology and fully modulating gas valves. Gas is burned only when hot water is required, and the tankless unit uses only the exact amount of gas required for the demand. This can save between 30 percent and 50 percent on water heating energy use. However, when the tankless equipment is firing, it typically requires more gas than a tank-type heater would for the identical demand. This, in turn, usually requires upsizing the gas service. Gas-line sizing charts must therefore be referenced.
Company News: Bosch’s focus is on serving our customers with high efficiency products for room climate and water heating that include leading technologies like geothermal heat pump, air-to-water heat pump water heaters and gas condensing water heating technology. Bosch enhances the quality of life by providing solutions,
which are both innovative and beneficial. Bosch is celebrating its 125th anniversary in 2011. Additional information can be accessed at
www.bosch.com and
www.125.bosch.com. Tankless Forecast:Very strong growth on condensing high
efficiency technology is expected to surpass the non- condensing segment by mid-2013; moderate growth on hybrid solutions. • The main driver for Bosch installers is with retrofit business.
Bosch sees commercial as an ideal segment for its growing product portfolio with good opportunities, however residential installations are the bulk of today’s business. • Solar Thermal Systems: The federal, state and local
incentives are a positive driving force in the residential segment. Commercial is the main driver for Bosch Solar Thermal at the moment with large scale projects to be announced very soon.
