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 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)
- Fuel type and first-hour/GPM sizing change the equipment cost.
- Removal and disposal of the old unit is sometimes a hidden add-on.
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
Get an apples-to-apples bid
- 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.
- Decide tank vs. tankless first, then compare like models.
Questions to ask Des Moines 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?

What affects tank water heater replacement cost the most?
Worth knowing first: replacing a standard storage-tank water heater, including the unit and installation. What should you watch? Equipment or material grade, the home's size and complexity, local labor rates, and your cold climate zone — in roughly that order.
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 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 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.
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.
