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 Rockville
Why winter is expensive: it's failure season, when cold groundwater stresses old units and emergency calls flood in. A 10+ year-old tank replaced proactively, before it dies, skips that spike completely.
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
- Confirm old-unit removal and disposal are in the price.
- Ask whether code upgrades (expansion tank, venting) are included.
- Match the first-hour rating / GPM to your household size.
- For tankless, ask if the gas line or electrical panel needs upgrading.
Questions to ask Rockville 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?

What affects tank water heater replacement cost the most?
Replacing a standard storage-tank water heater, including the unit and installation. That's the baseline — the price moves from there. What moves the price most: equipment or material grade, your home's size and complexity, local labor rates, and the mixed climate zone.
Tank or tankless — and what should you budget?
Three formats, three very different cost profiles. Our editors on how to decide which one actually fits your household.
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 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.
Start from how long you'll own the house. A short stay or a tight budget points to a tank, a full household settling in leans tankless, and if the monthly bill is what you're minimizing, the heat-pump's efficiency and rebates pull ahead.
