• Only run automatic dishwashers when completely full, the dishwasher uses the same amount of water and electricity whether it is full or just has a few cups in it.
• First and foremost, have your furnace and gas appliances serviced annually by a qualified contractor to ensure safety and maximum energy-efficiency. As you "tighten up" your home for energy-efficiency, you may even want to install a carbon monoxide detector for added safety.
• Set water heater temperature at 120 degrees and install water-flow restrictors in showerheads and faucets. Water-saving showerheads and faucet aerators save up to 50% on your hot water use. Simply unscrew the old one and screw on the new one.
• Flushing your water heater tank every year or so is a wise precaution which could extend the life of your tank by preventing the build-up of sediment. (However, if your tank hasn't been flushed for over five years, flushing it now and disrupting the sediment could actually expose a leak.)
