Tankless water heater installation by flow rate (GPM): Birmingham vs Hoover

|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,150–$4,050 | $2,150–$4,050 |
| 7–9 GPM (2–3 people, 2 baths) | $2,550–$4,700 | $2,550–$4,700 |
| 9–11 GPM (3–4 people, 2–3 baths) | $2,900–$5,150 | $2,900–$5,150 |

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?
Three formats, three very different cost profiles. Our editors on how to decide which one actually fits your household.
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 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 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 cheapest to install and the cheapest to run are rarely the same unit. Tanks win the first, heat-pumps win the second where the install spot allows, and tankless sits between them — trading a higher upfront number for a supply that never quits.
