EPA Announces New Energy Star Requirements for Dishwashers and Furnaces

Monday, July 25th, 2011

New Energy Star requirements for dishwashers and furnaces will go into effect early next year, the EPA announced last week.

Effective Jan. 20, 2012, Energy Star will require both standard-sized and compact residential dishwashers to be between 10% and 30% more energy efficient than conventional models, and about 8% more efficient than current Energy Star models, to qualify.

In addition, beginning Feb. 1, 2012, contractors and consumers will be able to identify Energy Star-qualified furnaces appropriate for particular climate zones:
–The furnaces that meet the new requirements for the southern half of the country will be labeled with a specific U.S. South Energy Star mark and will be up to 12% more energy efficient than baseline units.
–Qualified furnaces in the northern half of the U.S. and Canada will bear the standard Energy Star logo and will be up to 16% more energy efficient than baseline models.

The new requirements for residential dishwashers and furnaces are among 20 revisions to product requirements expected to be completed this year.

Tankless Water Heater Manufacturers A.O. Smith, Takagi Join Forces

Wednesday, June 16th, 2010

Jan.16 — Tankless water heater manufacturer A.O. Smith announced a joint venture with Japanese manufacturer Takagi in which A.O. Smith will manufacture, market, and distribute Takagi tankless units in North America.

As part of the deal, A.O. Smith will take over management of Takagi’s existing North American sales and distribution. The company plans to continue to offer existing and new products under the Takagi name as well as that of A.O. Smith and its wholesale brands, said A.O. Smith vice president of marketing Mike Parker in a conference call with the media.

According to Ajita Rejendra, president of A.O. Smith, the partnership will combine the leading-edge technological expertise of Takagi, which recently unveiled its second generation condensing tankless water heaters, with A.O. Smith’s national branding, marketing, customer relations, and distribution strength.  “Our objective is to be the market leader in North American, and the Takagi brand plays a big role in that,” he said. “This arrangement changes everything.”

The deal is expected to close in the third quarter. –Katy Tomasulo

American Hometec, A.O. Smith, and Rheem Unveil New Efficient Water Heater Offerings

Thursday, April 29th, 2010
American Hometec C-10

American Hometec C10

For green-built homes and remodels, high-efficiency water heaters are one of the most common upgrades, especially in light of recent tax and rebate incentives. Most of the time, this means going tankless, but lately also has included a new crop of high-efficiency “hybrid” tank models. In recent weeks, several new technologies landed on our desks.

American Hometec is touting the coil-less technology of its new C10 electric tankless water heater. The first of its kind in the U.S., according to the company, the technology heats water indirectly with quartz tubes; because electric components are not in direct contact with the water, lime-scale buildup is eliminated, according to the firm, increasing durability and helping to maintain the unit’s 95% to 98% efficiency over the long-term.

Three capacity settings—4.2 kW, 6.4 kW, and 8.5 kW—allow one unit to accommodate multiple needs; it has a rise of .4 – 1.3 gpm. The C10 is the first in a line of coil-less electric and Energy Star-certified gas models that will be rolled out this year.

A.O. Smith Voltex

Manufacturer A.O. Smith entered the hybrid water heater market this week with the introduction of Voltex. Similar to recently introduced hybrid technologies from GE and Rheem, Voltex uses heat pump technology to pull heat from the air and transfer it to water in the tank. It has three operating mode to accommodate varying levels of demand. The Energy Star-rated electric unit uses half the energy of a standard tank-type heater, the company says.

Rheem HP-50 and HP-40

Rheem HP-50 and HP-40

Finally, Rheem, which introduced a 50-gallon hybrid water heater last year, expanded its offerings with the HP-40, a 40-gallon model aimed at smaller households with low hot-water demand. The Energy Star-rated unit has an energy factor of 2.0, more than twice the efficiency of a traditional storage unit. –Katy Tomasulo

‘Cash for Caulkers’ Would Provide Rebates for Energy-Efficient Building Products, Retrofits

Wednesday, March 3rd, 2010

President Obama announced March 2 details on “Homestar,” a Cash for Clunkers-like rebate program designed to entice Americans to make their houses more energy efficient. The administration hopes the incentives will boost demand for building products such as insulation, efficient windows, and roofing in the same way car sales skyrocketed last year when consumers were offered rebates for trading in their gas-guzzling autos for more fuel-friendly models.

As outlined in the proposal, dubbed “Cash for Caulkers,” homeowners could be eligible for up to $3,000 in point-of-sale rebates for purchases of efficient product upgrades or whole-house audits/retrofits. Energy efficiency contractors and suppliers would market the rebates, provide them directly to consumers, and then be reimbursed by the federal government.

Under the first level of rebates, Silver Star, consumers would be eligible for up to $1,500 for a variety of home upgrades, including adding insulation, sealing leaky ducts, and replacing inefficient water heaters, HVAC units, windows, roofing, and doors. There would be a maximum rebate of $3,000 per home.

The more comprehensive Gold Star level would provide a $3,000 rebate to consumers for a whole-house energy audit and subsequent retrofit tailored to achieve a 20% energy savings. Additional rebates would be available for savings above 20%.

Administration officials are still working with Congress on details, including how long the program will run, but the White House expects Homestar to create “tens of thousands” of jobs, cut energy bills for families by $200 to $500 per year, and reduce the nation’s dependence on oil.

In a statement, the NAHB acknowledged the program’s economic possibilities: “This has the potential to be a real shot in the arm for the home building industry,” said association chairman Bob Jones. “It will help put America back to work, and it will help families save on monthly energy bills.”

Masco Home Services president Larry Laseter, one of three manufacturers who joined Obama at the event, urged Congress to approve the program. “We applaud the efforts of the administration to introduce a jobs creations program that is truly a win-win-win,” said Laseter. “The Homestar program will put our nation’s skilled construction force back to work, benefit homeowners through comfort and energy-efficient improvements to their existing homes, and result in long term energy efficiency gains.”

The National Lumber and Building Material Dealers Association was more cautious, telling Building Products’ sister publication ProSales it will be working closely with the White House, the DOE, and Congress to help ensure the program does not put small and large independent dealers at a disadvantage versus big-box retailers. The NAHB also expressed that equal access for all will be essential to the program’s success.
