With the rising cost of energy, every dollar saved
counts. In Hawaiʻi, about 40% of our energy costs
go to water heating, so following a few simple
habits can keep your hard-earned money where it
should be…in your wallet!
The less you use, the less you
pay.
Wash laundry with cold water, take short
showers, and set your dishwasher to cold
rinse.
Adjust your water heater.
Set the internal thermostat to 120°F to
avoid standby heat loss, which wastes
energy. If you have a timer function,
schedule shutdowns when you don’t need hot
water, saving you even more.
Maintain your water heater.
Regular tune-ups can extend the life and
efficiency of your water heater and avoid
early replacement. When it’s time to
upgrade or replace it, make sure to choose
the most efficient model for your home.
These steps alone can help you save as much as 15%
on your hot water costs, and new water heater
models tout up to 70% efficiency! So whether
you’re maintaining or replacing, check out Hawaii
