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

|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,500–$4,650 | $2,300–$4,200 |

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 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.
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.
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.
