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 tanklessThis page 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 tank 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 tankless units ended December 31, 2025 and is not available for 2026 installs. A condensing gas ENERGY STAR unit (UEF ≥0.95) still runs cheapest and may earn a utility rebate — check your gas utility and the DSIRE database.

Why tankless water heater installation 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)
- 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.
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
Get an apples-to-apples bid
- 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.
- Decide tank vs. tankless first, then compare like models.
Questions to ask Bel Air South Water Heaters pros

- 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?

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 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.
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 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.
Think of it as three different bets: tank is the safe, cheap one; tankless bets on convenience; heat-pump bets on the lowest operating cost and the best rebates. Pick the bet that matches your plans.
