Water heating is the second largest energy expense in most households, accounting for around 12 percent of your power bill.
If your water heater is more than 10 years old, consider replacing it with a new model to save energy and money on electric bills.
Electric vs. Natural Gas
Which is right for your home?
With gas water heater installation, the exhaust must be vented through an opening called a flu. That means installing PVC tubing through your home and out the roof. With an electric water heater, a special outlet or bare wiring is installed — no holes in your roof.
Gas water heaters need at least 6-18″ of ventilation around all sides and top, which means you can’t install the tank in a small closet or crawlspace. An electric tank can be confined in spaces without fear of gas buildup or an explosion.
Because electric water heaters use fewer parts, and those parts are subjected to less direct heat, they can last years beyond the lifespan of a gas water heater.
Electric water heaters cost less than gas heaters of the same size.
Other tips to save
  • A 10-minute shower uses about 25 gallons of water. Using a low-flow showerhead for your shower can save about five gallons of water over a typical bath. A low-flow showerhead can also save up to $145 per year on electricity.
  • Wrap your water heater and pipes with insulation. Be sure to follow the manufacturer’s instructions to ensure safety.
  • Lower your water heater thermostat to 120°F.
