| flow rate (GPM) | West Palm Beach 2026 range |
|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,250 – $4,100 |
| 7–9 GPM (2–3 people, 2 baths) | $2,600 – $4,800 |

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 tanklessThis page 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 |

Rebates & tax credits
The federal 25C tax credit for high-efficiency tankless units ended December 31, 2025 and is not available for 2026 installs. A condensing gas ENERGY STAR unit (UEF ≥0.95) still runs cheapest and may earn a utility rebate — check your gas utility and the DSIRE database.

Why tankless water heater installation quotes vary — and how to compare them fairly
Big gaps between bids come down to scope far more often than greed. This breaks down the levers and how to force a like-for-like comparison.
Why a quote looks high (or low)
- 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.
- 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.
- Ask whether code upgrades (expansion tank, venting) are included.
- Confirm old-unit removal and disposal are in the price.
- Match the first-hour rating / GPM to your household size.

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 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.
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.
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.
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.
