What does it really cost to run appliances?
The GENLESS website (run by the NZ Government) has a wealth of information to help you work out how much electricity your appliances are using.
Using the governments previous Energywise website, the following shows the cost of using appliances for 1 month (assuming power cost of 26c / kW)
6kW heatpump used for 1 hour each day for 1 month = $8.31
12 place dishwasher used once each day for 1 month = $6.17
6kg washing machine doing 1 cold wash each day for 1 month = $1.12
(note: a hot wash can use 10 times more electricity than a cold wash).
250 litre Fridge/Freezer running continuously for 1 month = $6.97
150 litre Chest Freezer running continuously for 1 month = $5.70
40 inch TV running for 5 hours each day for 1 month = $2.24
4kg Dryer used for 1 load each day for 1 month = $23.42 (= 78c per use)
