Cost to run
Yearly running cost — what most cost guides skip
Install price is only half the story. Over 10 years, the fuel bill often outweighs the price difference between models. National operating-cost estimates below (FTC EnergyGuide):
| Type | Per year | 10-year fuel |
|---|---|---|
Heat pump water heaterCheapest to run Cheapest to run — pulls heat from the air, ~3–4× more efficient than resistance. | $130 | $1,300 |
Gas tankless On-demand gas; no standby loss, so cheaper to run than a gas tank. | $270 | $2,700 |
Gas storage tank Low running cost where natural gas is cheap; some standby heat loss. | $330 | $3,300 |
Electric tankless On-demand electric; needs a heavy electrical service upgrade. | $500 | $5,000 |
Electric storage tankThis page Cheapest to buy, most expensive to run at national electricity prices. | $570 | $5,700 |

Rebates & tax credits
The federal 25C tax credit for high-efficiency water heaters ended December 31, 2025 and is not available for 2026 installs. Many gas and water utilities still offer their own rebates on ENERGY STAR condensing gas tanks — check your provider and the DSIRE database — and the lower running cost adds up over the tank's life.

Why tank water heater replacement quotes vary — and how to compare them fairly
Two contractors can price the same job thousands apart. Almost always it's the scope each assumed — here's what drives the gap and how to close it.
Why a quote looks high (or low)
- Fuel type and first-hour/GPM sizing change the equipment cost.
- Removal and disposal of the old unit is sometimes a hidden add-on.
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
Get an apples-to-apples bid
- Decide tank vs. tankless first, then compare like models.
- For tankless, ask if the gas line or electrical panel needs upgrading.
- Confirm old-unit removal and disposal are in the price.
- Match the first-hour rating / GPM to your household size.

- 3For tankless: does my gas line or electrical panel need an upgrade?
- 4What's the first-hour rating / GPM, and is it sized for my household?
- 5What does the warranty cover, and who handles warranty service?

What affects tank water heater replacement cost the most?
Replacing a standard storage-tank water heater, including the unit and installation. What moves the price most: equipment or material grade, your home's size and complexity, local labor rates, and the hot climate zone.
Tank or tankless — and what should you budget?
Tank, tankless or heat-pump — the format you pick shapes the bill today and the utility bill for years after. Our editors weigh the trade-offs.
The simple-swap case
A matching tank replacement skips every costly upgrade that comes with changing formats. Same footprint, same connections, same vent, so labor stays low and the crew is usually gone by midday. It's the obvious answer when the budget is thin and the old setup was never the problem.
The heat-pump case
A heat-pump (hybrid) water heater costs the most upfront but slashes operating cost and earns the strongest utility rebates where offered — the long-run winner where the install location suits it.
The tankless case
Going tankless means paying more at install — often for a resized gas line or a dedicated electrical circuit — in exchange for hot water that never runs dry and a unit that outlives two conventional tanks. Dropping the standby loss of a constantly reheated reservoir trims the monthly bill on top of that. It fits a full house that isn't selling anytime soon.
Start from how long you'll own the house. A short stay or a tight budget points to a tank, a full household settling in leans tankless, and if the monthly bill is what you're minimizing, the heat-pump's efficiency and rebates pull ahead.
