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.
Cheapest time for tank water heater replacement in San Antonio
Winter is when tanks fail most, because cold incoming water and heavy demand push an aging unit past its limit — right when everyone needs an emergency replacement at emergency prices. Swap it proactively in a slower month instead.
Why tank water heater replacement quotes vary — and how to compare them fairly
One bid high, one low, same house? The variable is scope. Here's what pushes the figure up or down and how to get quotes you can actually compare.
Why a quote looks high (or low)
- 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.
- 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.
- Confirm old-unit removal and disposal are in the price.
- For tankless, ask if the gas line or electrical panel needs upgrading.
- Ask whether code upgrades (expansion tank, venting) are included.
Questions to ask San Antonio Water Heaters pros

- 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?

In plain terms, 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 tankless case
The tankless premium buys longevity and endless supply: nothing sitting hot around the clock, a lifespan roughly double a tank's, and no cold showers when demand spikes. The catch lives in the setup, since most retrofits need a bigger gas line or an electrical upgrade first. Larger households planning to stay put recover that cost fastest.
The simple-swap case
When money is the constraint and the existing tank has kept up with the household, dropping in the same fuel type and capacity is the least disruptive move. No venting rework, no new gas line, no panel space to find — a plumber can pull the old unit and set the new one before lunch.
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 right format depends on how long you're staying and what you're optimizing for: upfront cost favors tank, convenience favors tankless, and long-run savings favor heat-pump.
