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
A wide spread between bids rarely means someone is overcharging; it usually means they priced different work. Below is what moves the number and how to line the quotes up.
Why a quote looks high (or low)
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
- Fuel type and first-hour/GPM sizing change the equipment cost.
- Removal and disposal of the old unit is sometimes a hidden add-on.
Get an apples-to-apples bid
- Match the first-hour rating / GPM to your household size.
- Confirm old-unit removal and disposal are in the price.
- Ask whether code upgrades (expansion tank, venting) are included.
- Decide tank vs. tankless first, then compare like models.
Questions to ask Summerville Water Heaters pros
The only honest way to compare is to hold every quote to one checklist. Start with these.
- 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?

The estimate above already covers the Water Heaters permit Summerville generally requires for this job, so the $150 or so it costs won't land as a surprise.

Worth knowing first: replacing a standard storage-tank water heater, including the unit and installation. Grade of equipment and materials tops the list, followed by home size and complexity, local labor, and the hot climate zone.
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 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 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 heat-pump case
A hybrid heat-pump unit carries the steepest sticker price and draws the largest utility rebates on the market, then pays that back by pulling warmth from the surrounding air instead of generating heat — operating cost falls to a fraction of a standard electric tank's. The condition is location: it wants a roomy, temperate spot like a garage or basement to perform.
Match the format to your household and how long you'll stay. Tank for tight budgets, tankless for endless hot water, heat-pump for the lowest running cost and biggest rebates.
