Reduce Your Hot Water Bill. It's more than the water heater:
- Fix leaky pipes and faucets. Just a measly drop per second from a dripping faucet adds up to 200 gallons a month! That's five tankfuls of hot water from an average residential water heater.
- Practice faucet control. Don't let hot water run before you get in the shower or while you're shaving.
- Install low-flow showerheads. Available at home improvement stores and plumbing supply dealers, these economical energy savers quickly pay for themselves. With better models, you can't tell that there's less water coming out of the showerhead.
- Insulate hot water pipes. Installing pre-cut foam pipe insulation on all hot water lines can save five to 10 percent on water heating costs.
- Wash clothes in cold water whenever possible.
- Wrap the water heater. A water heater insulation wrap will cut down on standby losses from the tank. Do not install insulation on top of a natural gas water heater-just the sides.
