Tankless water heater installation by flow rate (GPM): Brentwood vs Brooklyn
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).
| Size | Brentwood | Brooklyn |
|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,750–$5,100 | $2,750–$5,100 |
| 7–9 GPM (2–3 people, 2 baths) | $3,200–$5,900 | $3,200–$5,900 |
| 9–11 GPM (3–4 people, 2–3 baths) | $3,700–$6,500 | $3,700–$6,500 |
| 11+ GPM (5+ people / whole-home) | $4,300–$7,100 | $4,300–$7,100 |

Cheapest time for tankless water heater installation in either city
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.
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 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.
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.
Budget and time horizon settle this more than any spec sheet. A tank clears the lowest hurdle, tankless buys convenience and a longer life, and a heat-pump chases the cheapest years of operation once it has the space to run.
