Electricity bill very high due to hot water system - What to do?
I've recently changed homes. The first bill came in and the electricity read is 516.23 kWh(A) for the month for just myself.
Apparently this is more than a 5 person household uses.
I'm not doing anything crazy with the electricity, I have an energy efficient fridge, an old washing machine and dryer, and use an aircon unit.
I notice from looking at Energy Australia where it shows every half hour of usage there's a big spike when I shower, as well as a smaller spike at mid day and about 2am when I am not using any water, and some peaks when I must be washing the dishes.
It must be the hot water unit.
What can I do about this, if anything?
Obviously using the hot water is a part of life so I'm not going to sacrifice that, but is there any suggestions?
The bill is $140 and I haven't even been home during the day.
