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

Tank or tankless — and what should you budget?
Three formats, three very different cost profiles. Our editors on how to decide which one actually fits your household.
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
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
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.
