Good to know
The EPA figure includes the electricity to heat the wash water with an electric water heater, at 295 loads a year. With a gas water heater, your electric cost is lower. Washing in cold water saves the most.

Water use

3,452 gallons a year at 295 loads, per the EPA test. Integrated water factor 2.6 gallons per cycle per cu ft (federal maximum 4.7; lower is better).

We show water in gallons only. Water and sewer rates vary too much by town for a fair national dollar figure.
