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.

Wait for a winter failure and you're paying rush rates on a unit already past 10 years, when the cold incoming water finally does it in. Replace it on your own schedule in spring or fall and you avoid that premium entirely.
Why tank water heater replacement quotes vary — and how to compare them fairly
Two bids for the “same” job can differ by thousands. Usually it's scope, not greed — here's what moves the number and how to get an apples-to-apples comparison.
Why a quote looks high (or low)
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
- Removal and disposal of the old unit is sometimes a hidden add-on.
- Tank vs. tankless is a different job — tankless often needs gas-line or electrical-panel upgrades.
Get an apples-to-apples bid
- Match the first-hour rating / GPM to your household size.
- For tankless, ask if the gas line or electrical panel needs upgrading.
- Ask whether code upgrades (expansion tank, venting) are included.
- Decide tank vs. tankless first, then compare like models.
Questions to ask Reston Water Heaters pros
Comparing quotes is only fair when they cover the same scope. Ask every bidder these before you sign.
- 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?
The format choice drives both upfront cost and lifetime value. How our editors think about it.
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 tankless case
Tankless costs more upfront and may need a gas-line or electrical upgrade, but it lasts longer, never runs out of hot water and trims standby energy loss — strongest for larger households planning to stay put.
There's no universally "best" water heater — only the one that fits your budget and timeline. Tight budget, go tank; want endless hot water, go tankless; optimizing for the lowest bill, go heat-pump.
