DIY vs. hiring a pro

An electric tank swap is within reach for an experienced DIYer. Gas units involve combustion venting and carbon monoxide risk, and most jurisdictions require a permit and inspection either way.
Ways to save
Practical levers that lower the bill without cutting quality.
- 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.
Questions to ask your contractor
- 01Is haul-away of the old unit and the permit included?
- 02Does the install need an expansion tank or a code-required pan?
- 03Will my current gas line or electrical service handle this unit?
- 04What is the first-hour rating, not just the tank size?
- 05What are the separate tank and labor warranties?
- 06How long will we be without hot water?
