|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,650–$4,950 | $2,350–$4,350 |

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?
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 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 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.
