Heat pump water heater installation by tank capacity: Federal Way vs Spokane

|---|---|---|
| 40 gal (1–2 people) | $2,650–$4,400 | $2,300–$3,800 |

Cheapest time for heat pump water heater installation in either city
An aging tank tends to give out in winter, when it's working hardest against cold incoming water — and that's exactly when replacement costs the most. Get ahead of it.
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 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 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 heat-pump case
For the lowest running cost of the three, the heat-pump water heater wins outright, and where utilities offer incentives the rebates behind it are the richest available. You pay for that advantage up front, and the unit needs the right home — a warm, well-ventilated area with real clearance. Wedge it into a tight closet and the savings disappear.
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.
