| tank capacity | Federal Way 2026 range |
|---|---|
| 40 gal (1–2 people) | $2,650 – $4,400 |
| 50 gal (2–4 people) | $2,900 – $4,900 |

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 runThis page 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 tank Cheapest to buy, most expensive to run at national electricity prices. | $570 | $5,700 |
Verified July 2026. Figures use FTC EnergyGuide / DOE (national average fuel prices) — your state's fuel prices move them: where electricity is cheap or gas is expensive the ranking shifts. Check current EIA residential energy prices for your state.
Rebates & tax credits
The federal 25C credit for heat-pump water heaters (up to $2,000) ended December 31, 2025 and is not available for 2026 installs. State and utility rebate programs may still cut the cost — check the DSIRE database, your state energy office, and your utility — and a heat-pump unit's very low running cost pays back over time.
Cheapest time for heat pump water heater installation in Federal Way
Tanks fail most in winter when incoming water is cold and demand is high — emergency-rate territory. Replacing a 10+ year-old unit proactively in a slow month avoids the premium.
Why heat pump water heater installation quotes vary — and how to compare them fairly
Price differences on an identical job trace back to the assumptions each contractor made; understand those and the 'expensive' bid often turns out fair.
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.
- Fuel type and first-hour/GPM sizing change the equipment cost.
Get an apples-to-apples bid
- For tankless, ask if the gas line or electrical panel needs upgrading.
- Match the first-hour rating / GPM to your household size.
- Decide tank vs. tankless first, then compare like models.
- Confirm old-unit removal and disposal are in the price.
Questions to ask Federal Way Water Heaters pros
A fair comparison starts with identical questions. Ask each contractor the following before anything gets signed.
- 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?

Most Federal Way jurisdictions require a Water Heaters permit for this work. Budget roughly $175 for the permit; it is already included in the estimate above.
What affects heat pump water heater installation cost the most?
Worth knowing first: installing a hybrid heat pump water heater — the most energy-efficient option, with the lowest operating cost. The biggest drivers are equipment/material grade, the size and complexity of your home, local labor rates, and your climate zone (mixed).
Tank or tankless — and what should you budget?
What a water heater costs to install and what it costs to run rarely move together, and the format is the lever between them. Tank, tankless, and heat-pump each strike that balance differently.
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 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 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.
Budget and time horizon settle this more than any spec sheet. A tank clears the lowest hurdle, tankless buys convenience and a longer life, and a heat-pump chases the cheapest years of operation once it has the space to run.
