My washer and dryer energy usage measurements

Since getting my new smart meter I've been tracking daily electric consumption and a pattern has started to emerge.

I average 25 kwh/day right now doing nothing special. If I heat with the heat pump it adds 20 kwh If I do a load of laundry in the dryer it adds 5 kwh. If I do 2 loads it add 10 kwh. So I'm updating my laundry spreadsheet to show dryer is using 5 kwh per load. It does have a sensor so it's just an estimate and small loads will take less time but I tend to load it right up. This means I save about 40 cents each time I hang the laundry on the line.

Laundry wise things are staying pretty stable. In 14 months it's been 313 cold loads and 42 hot loads. 263 loads in the dryer and 20 partial/tumble drys.

my clothesline has saved me $23.87 since that time and using cold water has saved me $18.32

I will say I miss summer time though. Yesterdays towels were still quite damp after 6 hours in the shade/wind/sun since the sun is low enough half my clothes line is shaded this time of year...
