Tankless water heater installation by flow rate (GPM): Ann Arbor vs Brentwood
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 | Ann Arbor | Brentwood |
|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,400–$4,450 | $2,300–$4,200 |
| 7–9 GPM (2–3 people, 2 baths) | $2,800–$5,200 | $2,650–$4,900 |
| 9–11 GPM (3–4 people, 2–3 baths) | $3,250–$5,700 | $3,050–$5,400 |
| 11+ GPM (5+ people / whole-home) | $3,750–$6,200 | $3,550–$5,850 |

Cheapest time for tankless water heater installation in either city
The failure pattern is predictable: cold water plus heavy winter demand kills aging tanks, and everyone needing emergency service pushes prices up together. Getting ahead of it in a quiet month sidesteps the rush.
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 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
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 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.
