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.

An aging tank tends to give out in winter, when it's working hardest against cold incoming water — and that's exactly when replacement costs the most. Get ahead of it.
Why tank water heater replacement quotes vary — and how to compare them fairly
When two quotes for one project diverge by thousands, the cause is usually what each one includes, not markup — here's how to read the difference.
Why a quote looks high (or low)
- Fuel type and first-hour/GPM sizing change the equipment cost.
- Tank vs. tankless is a different job — tankless often needs gas-line or electrical-panel upgrades.
- Removal and disposal of the old unit is sometimes a hidden add-on.
Get an apples-to-apples bid
- Ask whether code upgrades (expansion tank, venting) are included.
- For tankless, ask if the gas line or electrical panel needs upgrading.
- Decide tank vs. tankless first, then compare like models.
- Match the first-hour rating / GPM to your household size.
Questions to ask Sumter Water Heaters pros
A fair comparison starts with identical questions. Ask each contractor the following before anything gets signed.
- 1Will the new unit meet current code (expansion tank, venting, seismic straps, drain pan)?
- 2Is removal and disposal of the old heater included in the price?
- 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?

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 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.
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 simple-swap case
If your current tank suits your household and the budget is tight, a like-for-like tank replacement is the cheapest, fastest job — no gas-line or panel upgrades, done in a morning.
The cheapest to install and the cheapest to run are rarely the same unit. Tanks win the first, heat-pumps win the second where the install spot allows, and tankless sits between them — trading a higher upfront number for a supply that never quits.
