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 Charleston
The failure pattern is predictable: cold water plus heavy winter demand kills aging tanks, and everyone needing emergency service pushes prices up together. Getting ahead of it in a quiet month sidesteps the rush.
Why tank water heater replacement quotes vary — and how to compare them fairly
Two contractors can price the same job thousands apart. Almost always it's the scope each assumed — here's what drives the gap and how to close it.
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.
- Tank vs. tankless is a different job — tankless often needs gas-line or electrical-panel upgrades.
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 Charleston Water Heaters pros
You can't judge bids side by side unless they cover the same ground; run through these with every pro on your list.
- 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 Charleston, this usually needs a Water Heaters permit (around $125). The estimate above already accounts for it.
What affects tank water heater replacement cost the most?
Replacing a standard storage-tank water heater, including the unit and installation. From there, a handful of specifics push the final number up or down. Your mixed climate zone plays a part, but equipment/material grade, the size and complexity of the home, and local labor rates weigh in just as heavily.
Tank or tankless — and what should you budget?
Before the brand or the size, the biggest decision in a water heater budget is the format. Here's how our editors think through 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
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 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.
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.
