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.
