By size

Tankless water heater installation by flow rate (GPM): Champaign vs Chicago

Tankless units are sized by flow rate — gallons per minute (GPM) — rather than tank size. Add up the fixtures you'd run at once: a shower is ~2 GPM, so a larger household needs a higher-GPM unit (or two).

SizeChampaignChicago
5–7 GPM (1–2 people, 1 bath)$2,300$4,300$2,700$5,050
7–9 GPM (2–3 people, 2 baths)$2,700$4,950$3,200$5,900
9–11 GPM (3–4 people, 2–3 baths)$3,100$5,450$3,650$6,450

Editors' roundtable

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

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 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

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.

Our take

Match the format to your household and how long you'll stay. Tank for tight budgets, tankless for endless hot water, heat-pump for the lowest running cost and biggest rebates.
