When we talk about residential energy efficiency, heating, cooling and insulation usually come to mind. Yet sitting in every home’s utility room is one of the single most power hungry appliances in your house- the conventional clothes dryer. 

How much energy??

A standard electric dryer uses roughly 4,000 to 5,000 watts, meaning the typical load of laundry uses 3-5 kilowatt-hours (kWh) of electricity per load. With electricity prices sitting at roughly $.20/kWh, that’s $.60 to $1.00 per load. For the typical family running six loads a week, that adds up to 1,200 kWh annually, or $240. That’s roughly equal to the electricity required to power two full-sized refrigerators for an entire year. 

Improving Safety

Beyond the direct electricity consumption, conventional vented dryers also blast hundreds of cubic feet of conditioned indoor air outside per minute, forcing your heating system to work harder to replace it. Those same vent ducts also create serious home safety risks. Dryers result in thousands of home fires each year, with trapped lint being the main ignition source. As lint accumulates in duct transitions, accordion folds, elbows, and exterior wall flaps, the restricted airflow causes temperatures to spike, often resulting in fire. Preventing both energy waste and reducing fire risk requires constant vigilance, like cleaning the lint filter before every load, choosing metal ducting over flexible accordion ducting, and keeping exterior exhaust flaps clear.

Two approaches to saving energy

For households looking to lower energy bills and eliminate venting and fire risks altogether, heat pump dryers offer a major step forward. A heat pump dryer operates much like a built-in dehumidifier. It warms the air to draw moisture out of clothes, cools that air to condense the water away, and reheats the dry air to continue the cycle. This reduces energy use by 50 to 60% versus the conventional electric clothes dryer.

Major manufacturers like GE, LG and Samsung now offer full-size heat pump models, including all in one washer/dryer combinations like the GE Profile UltraFast and LG WashCombo. These units wash and dry full loads in roughly two hours, and eliminate the need to transfer wet clothes between machines. Because heat pump dryers use significantly less power than conventional dryers, these full size units plug directly into standard 120 volt outlets and require no external venting. And for those replacing gas dryers, this 120 volt plug and play setup avoids the added expense of installing a dedicated high voltage outlet.

And for no cost at all, simple air drying remains the best option. Using an outdoor clothesline or indoor drying rack requires no electricity and eliminates heat-related clothes shrinkage and garment breakdown. Even the half step of air drying a portion of your weekly laundry while saving the dryer for heavy towels can yield significant savings on your electric bill. 

While washers and dryers rarely drive home efficiency conversations, their impact on monthly energy bills is significant. Making thoughtful adjustments to how you dry clothes and the equipment you use pays immediate dividends in lower utility bills and reduced energy waste.
