How many kilowatts are used to heat an average washing machine load?

Question

I'm trying to figure out how much energy I have saved using only cold water on my last 20 large loads of laundry. I can't figure this out because all of the statistics I've seen only shows me per year. Example: http://michaelbluejay.com/electricity/laundry.html

Any help would be great it's for an environmental science presentation.

Answer 1

if the rating of the heater is, say 2kW, and it heats the water for say 15 minutes, that would be 0.5 kWh (kilowatt.hours) per load.

Answer 2

who knows!
