|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,350–$4,350 | $2,750–$5,100 |

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?
Before the brand or the size, the biggest decision in a water heater budget is the format. Here's how our editors think through it.
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.
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 right format depends on how long you're staying and what you're optimizing for: upfront cost favors tank, convenience favors tankless, and long-run savings favor heat-pump.
