New Efficiency Standards for Hot Water Heaters

The National Association of Home Builders has condensed the DOE page on the new Efficiency Standards for Hot Water Heaters. The good news is if you buy the unit, you can install it, until existing stocks are used up. There are also some alternatives in specifying and installation you can consider.

Elec DHWNew residential water heater energy-efficiency standards that go into effect April 16 will require changes to the installation of many residential water heaters. Most water heaters with a capacity of 55 gallons or less will require more installation space, and those larger than 55 gallons in capacity will see additional, more significant changes. However, products manufactured before April 16 can still be bought and installed after the changeover date.

These new efficiency standards will require much higher Energy Factor (EF) ratings for larger water heaters, making a huge impact, especially on how these types of water heaters are manufactured, distributed, installed and/or vented.

PV DHWThe more common-sized water heaters of 55 gallons or less will likely be larger by roughly 2 inches in height and diameter to account for the additional insulation needed to meet the new standard. This may require builders to account for the increased size in their design.

It is expected that replacement water heaters installed in closets will present the biggest problems: They may require installing an applicance with reduced water capacity, selecting a much taller tank of the same diameter or a switching to a tankless water heater if space does not allow for a simple change-out.

As more information is available from manufacturers and the federal Department of Energy, NAHB will update this page.  Continue Reading

The First Clothes Dryers to Earn the Energy Star Label Now Available Nationwide

ES DryerEnergy Star Press Release Date: 02/10/2015

WASHINGTON –The U.S. Environmental Protection Agency (EPA) announced today that Energy Star certified clothes dryers are now available nationwide through major retailers. At least 45 models of dryers earning the Energy Star label, including Whirlpool, Maytag, Kenmore, LG, and Safemate, are at least 20 percent more efficient and now available at prices comparable to standard dryers. 

“Dryers are one of the most common household appliances and the biggest energy users,” said U.S. EPA Administrator Gina McCarthy. “EPA’s Energy Star certified clothes dryers offer Americans an opportunity to save energy and do their part to combat climate change. By working with industry, we are bringing innovative technology to market that’s good for the planet.”

Clothes dryers consume more energy than any other appliance in the home, and 80 percent of American homes have dryers. But unlike clothes washers, which have seen a 70 percent drop in energy use since 1990, the energy efficiency of most dryers has not improved. If all residential clothes dryers sold in the U.S. were Energy Star certified, Americans could save $1.5 billion each year in utility costs and prevent greenhouse gas emissions equal to the electricity use from more than 1.3 million homes.

The efficiency specifications were developed with extensive input from manufacturers, retailers, the U.S. Department of Energy, and environmental groups. Manufacturers meet the specification requirements by incorporating advanced sensors that more effectively detect when clothes are dry and stop the dryer.

Energy Star certified dryers include gas, electric and compact models. The Energy Star label can also be found on dryers that feature new advanced heat pump technology and are 40 percent more efficient than conventional models. Heat pump dryers recapture the hot air used by the dryer and pump it back into the drum. By re-using most of the heat, a heat pump dryer is more efficient and avoids the need for ducts.
