complete and can be implemented as

new federal minimum standard 5

years later. “Tier 2” Heat Pump Dryers

Flow Bins (CFM)

Typical DOE 2005 and 2011

Air flow rates are lower Questions

• What is the real world vent rate?

• How does this impact drying time?

• Does this make them similar in

performance to HP dryers?

24% of ducts had

substantial air flow

Summary and Comparison Table

19

NEEA Study Summary

Energy use was higher than expected More loads per year DOE = 283/yr

NEEA = 337/yr

Longer run times (min) DOE = 27 min

NEEA = 58 min

Ventilation Rate Impact Negligible

Considerable Variability Between models

Owner behavior

Types of laundry loads

Auto termination doesn’t always work well

Consumer Behavior Medium heat is most common

Many selected “Extra Dry”

124% as many dryer loads as washer loads

Developing a Qualified Products List

Utility Wants Energy Star Alignment w/D2

Additional Data (Cycle time, Heavy Load)

Real World Validation (field studies)

Consumer Preferences and Settings

Manufacturer Wants $$$$ incentive commitment

Marketing and consumer education

3rd party validation

28

Potential Market Support for Dryer*

Early-stage incentives* $400/unit x 100,000 = $40 million

Mid-stage incentives* $300/unit x 200,000/yr = $60 million/yr

Duration ~ 2-5 years

Late-stage incentives $150/unit x 1,000,000/yr = $150 million/yr

Duration ~2-10 years

* Assumes unit provides 400kWh/yr savings compared to electric resistance

Values are estimates reflective of similar types of efficiency investments and

participation by NW, CA, and NY utilities.

** Assumes broader nation wide incentive programs.
