Tankless water heater installation by flow rate (GPM): Ankeny vs Davenport
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).

|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,350–$4,350 | $2,250–$4,250 |

Cheapest time for tankless water heater installation in either city
Tanks fail most in winter when incoming water is cold and demand is high — emergency-rate territory. Replacing a 10+ year-old unit proactively in a slow month avoids the premium.
Tank or tankless — and what should you budget?
Fuel type and household size come after the real fork in the road: tank, tankless, or heat-pump. That single choice sets both the install bill and every hot-water bill that follows.
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 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 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.
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.
