Tankless water heater installation by flow rate (GPM): Arlington vs Worcester

| Size | Arlington | Worcester |
|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,750–$5,100 | $2,500–$4,650 |
| 7–9 GPM (2–3 people, 2 baths) | $3,250–$5,900 | $2,950–$5,400 |
| 9–11 GPM (3–4 people, 2–3 baths) | $3,700–$6,500 | $3,350–$5,900 |
| 11+ GPM (5+ people / whole-home) | $4,300–$7,100 | $3,900–$6,450 |

Why winter is expensive: it's failure season, when cold groundwater stresses old units and emergency calls flood in. A 10+ year-old tank replaced proactively, before it dies, skips that spike completely.
Tank or tankless — and what should you budget?
The format choice drives both upfront cost and lifetime value. How our editors think about it.
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 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 heat-pump (hybrid) water heater costs the most upfront but slashes operating cost and earns the strongest utility rebates where offered — the long-run winner where the install location suits it.
There's no universally "best" water heater — only the one that fits your budget and timeline. Tight budget, go tank; want endless hot water, go tankless; optimizing for the lowest bill, go heat-pump.
