Check out your water heater’s temperature setting and lower it to 120°F. Water heaters are extremely inefficient, and the higher the temperature setting, the more energy they waste.
Water heaters typically account for about 13% of a household’s utility expenses. If you lower your water heater setting from 150°F to 120°F, you could reduce its energy demand by up to 15%.
You can also try a tankless water heater, it only heats the water that you are using, instead of constantly heating and reheating water in a tank type water heater. The tankless water heaters can be up to 105% efficient, where as most tank type water heaters are only around 75% efficient.
