How Water Heater Costs Break Down
Water heater costs depend on whether you need a repair, a like-for-like replacement, or an upgrade to a different type. Each scenario has a very different price range.
Repair vs. Replace: The 50% Rule
If a repair costs more than 50% of a new water heater and your unit is past half its expected lifespan, replacement is usually the better investment. Tank water heaters last 8–12 years; tankless units last 15–20 years.
Water Heater Types Compared
- Standard tank (gas or electric): $1,200–$3,500 installed. Most affordable upfront. 8–12 year lifespan. Electric tanks are cheapest but cost more to operate.
- Tankless (gas): $2,500–$5,500 installed. Saves $100–$200/year on energy. Unlimited hot water. 15–20 year lifespan. May require gas line and venting upgrades.
- Heat pump water heater: $3,000–$6,000 installed. Uses 60–70% less energy than electric tanks. Qualifies for a $2,000 federal tax credit. Best choice for homes with electric water heating.
Hidden Costs to Watch For
The unit price is only part of the total cost. Installation adds $500–$2,000+ depending on complexity. Common extras include: new water lines ($100–$400), expansion tank ($40–$100, now code-required in many areas), permit ($25–$200), and haul-away of the old unit ($25–$100).

Should I repair or replace my water heater?

Is a tankless water heater worth it?
Tankless water heaters cost more upfront ($2,500–$5,500 vs $1,200–$3,500 for tank) but last twice as long and save $100–$200/year on energy. They pay for themselves in 8–12 years.
Does a heat pump water heater save money?
