I am trying to calculate the running cost of my clothes dryer and have bought myself an energy meter to check its usage.
I plugged the meter in, reset it, and then turned it over to the aggregate kWh mode and did a single drying session with wet clothes from the washing machine.
After the load had finished the meter read 1.828 kWh and the total time was 1h 13m.
So as I understand it, a single load used 1.828 kWh, and as we are doing about 7 loads per week that would be a total of 665 kWh / year. At the current rate of 33c per kWh the annual running cost is therefore about $219.
Now this to me is a bit strange as just about every website I have seen says that dryers should be costing upwards of $400 per annum for this kind of usage. In addition, my dryer is only a 2 out of 5 stars for energy efficiency.
Can anyone see a problem with my math or logic?
