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.
Cheapest time for tankless water heater installation in Tinley Park
Wait for a winter failure and you're paying rush rates on a unit already past 10 years, when the cold incoming water finally does it in. Replace it on your own schedule in spring or fall and you avoid that premium entirely.
Why tankless 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)
- Fuel type and first-hour/GPM sizing change the equipment cost.
- Code work (expansion tank, venting, drain pan, straps) may be excluded from a low bid.
- Tank vs. tankless is a different job — tankless often needs gas-line or electrical-panel upgrades.
Get an apples-to-apples bid
- Decide tank vs. tankless first, then compare like models.
- Match the first-hour rating / GPM to your household size.
- Ask whether code upgrades (expansion tank, venting) are included.
- For tankless, ask if the gas line or electrical panel needs upgrading.

- 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?

What affects tankless water heater installation cost the most?
Installing an on-demand tankless water heater, which heats water only as needed. From there, a handful of specifics push the final number up or down. Four things drive the number more than anything else — equipment/material grade, home size and complexity, local labor, and your cold climate zone.
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
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
Going tankless means paying more at install — often for a resized gas line or a dedicated electrical circuit — in exchange for hot water that never runs dry and a unit that outlives two conventional tanks. Dropping the standby loss of a constantly reheated reservoir trims the monthly bill on top of that. It fits a full house that isn't selling anytime soon.
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.
Think of it as three different bets: tank is the safe, cheap one; tankless bets on convenience; heat-pump bets on the lowest operating cost and the best rebates. Pick the bet that matches your plans.
