6. Lower Your Water Heater Temperature
There's nothing like the feeling of a nice hot shower, but lowering your water heater by just 10° F can save up to 12% on
your bill. Heaters should be set anywhere from 120° to 125°, which is still plenty hot when you need to relax.
Cost: A few minutes in your utility room
Savings: $30 or more per year on gas, oil, electricity or propane
