Ways to save in Seattle

  • Replace before it fails so you are not paying emergency rates.
  • Right-size the tank; oversizing wastes standby energy every day for a decade.
  • Check federal, state and utility rebates for heat pump water heaters — they can cover $500 to $2,000.
  • Stay with your existing fuel type unless energy math clearly favors switching.
  • Buy the unit yourself during a sale and pay only for installation labor.
