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 |

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 Billings
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 heat pump water heater installation quotes vary — and how to compare them fairly
One bid high, one low, same house? The variable is scope. Here's what pushes the figure up or down and how to get quotes you can actually compare.
Why a quote looks high (or low)
- 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.
- Removal and disposal of the old unit is sometimes a hidden add-on.
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 Billings Water Heaters pros
Quotes only compare cleanly when every bidder is pricing the same work — put these to each of them before you commit.
- 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 heat pump water heater installation cost the most?
Installing a hybrid heat pump water heater — the most energy-efficient option, with the lowest operating cost. That's the baseline — the price moves from there. The biggest drivers are equipment/material grade, the size and complexity of your home, local labor rates, and your climate zone (cold).
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 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 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 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.
There's no universally "best" water heater — only the one that fits your budget and timeline. Tight budget, go tank; want endless hot water, go tankless; optimizing for the lowest bill, go heat-pump.
