How much should this gap actually matter?
That 5% gap is small — for tankless water heater installation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

Tankless water heater installation by flow rate (GPM): Brentwood vs Richland

| Size | Brentwood | Richland |
|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,300–$4,200 | $2,400–$4,450 |
| 7–9 GPM (2–3 people, 2 baths) | $2,650–$4,900 | $2,800–$5,150 |
| 9–11 GPM (3–4 people, 2–3 baths) | $3,050–$5,400 | $3,200–$5,650 |

Winter is when tanks fail most, because cold incoming water and heavy demand push an aging unit past its limit — right when everyone needs an emergency replacement at emergency prices. Swap it proactively in a slower month instead.
Tank or tankless — and what should you budget?
Tank, tankless or heat-pump — the format you pick shapes the bill today and the utility bill for years after. Our editors weigh the trade-offs.
The simple-swap case
If your current tank suits your household and the budget is tight, a like-for-like tank replacement is the cheapest, fastest job — no gas-line or panel upgrades, done in a morning.
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.
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.
