Super-Efficient Dryers

Cycling into higher energy savings

Northwest consumers own six million electric clothes dryers, the largest energy-consuming standard appliance in most homes. Transforming these to more efficient heat pump clothes dryers represents a potential of 180 average megawatts (aMW) of energy savings for the region.

NEEA works with manufacturers to influence product design and minimize risk for its utility partners by conducting laboratory tests of new products before they are widely distributed in the market, and supporting manufacturers and retailers as they deploy tested products into the market. NEEA also works at the federal level to influence more stringent federal test protocols and more stringent
efficiency standards.

Now that these energy-efficient products are in the market, NEEA works with its partners to increase product availability and drive demand for heat pump clothes dryers.

  • Establishing the Market Baseline for Super-Efficient Clothes Dryers
    This report estimates the market baseline for the Super-Efficient Dryer Initiative in the absence of a NEEA initiative or the influence of a local utility program. According to the report, the average final estimate of the market adoption for super-efficient dryers is zero percent in 2015, and 31 percent by 2035. Adoption in the early years of the initiative will be slow, but would increase by 2020.

  • NEEA Clothes Dryer Field Study
    In 2013, NEEA studied the household laundry process in 50 homes. The purpose of the study was to understand the nature of household laundry loads, the number of laundry loads and laundry cycles (not the same thing) per year, and the energy use and operating characteristics of newer model clothes dryers. The participating homes for this focused study were chosen from the larger regional group of Residential Building Stock Assessment (RBSA) participants. The data has been used to support proposed changes to the federal test procedures for clothes dryers, and to support the development of NEEA’s residential clothes dryer initiative. The core field study protocols are now being used nationally and regionally to further support test procedure development and the NEEA clothes dryer initiative.

  • Emerging Technology Dryer Testing
    The Northwest Energy Efficiency Alliance (NEEA) contracted Ecova to conduct laboratory testing of the 2013 Environmental Protection Agency Emerging Technology Awardee for clothes dryers. The purpose was to determine if the dryer's success meeting the Emerging Technology specification would translate into success with the recent Energy Star specification, and how the dryer would perform when drying heavier weight test cloths more similar to "real world" conditions. The results show that as currently configured, the clothes dryer would not result in significant energy savings unless run times were extended well beyond typical consumer expectations. This does not invalidate the Emerging Technology award status but does raise the question if utilities should use this first efficient US dryer as a basis for incentive programs.

Heat Pump Clothes Dryers FAQ

NEEA works with manufacturers to support developing, testing and introducing new heat pump dryers with the potential to save enough energy to power 130,000 homes each year. We continue to work with the region plus national/international manufacturers to develop and test heat pump products to deliver even more energy savings for the Northwest.
