"Your hot shower or bath uses 15-30% of your household’s total energy, second
only to the heating and cooling of air.
More than half of all Australian households rely on electric water heaters with
a storage tank. These act like thermal batteries and often store more energy
than a home battery. Traditionally, these heaters operated during off-peak
hours overnight when power demand was low. This practice also helps maintain
stability for coal power stations.
But there’s a better option: cheap heating at daytime. More than 40% of
freestanding Australian houses now have solar. Switching water heaters to
charge during the day can soak up solar power going to waste – known as
curtailment – and make sure electricity supply and demand match.
In our new real world trial, we put this technique to the test and found it
works."
