A failed water heater feels urgent, but it's rarely a same-day emergency — which matters, because urgency is exactly when quotes get padded.
Tank versus tankless
Tankless units cost more upfront but take up less space and last longer; tank units are cheaper upfront and simpler to service. Neither is universally "better" — the right call depends on your household size and hot water usage, and a good quote explains that reasoning rather than just upselling the pricier option.
What should be included
- Correct sizing — gallons for a tank unit, or gallons-per-minute for tankless — matched to your household, not just a like-for-like swap.
- Code-required updates that often come with replacement: an expansion tank, proper venting, a drip pan, and seismic strapping in areas that require it.
- Permit, which many areas require for water heater replacement.
- Warranty length for parts versus labor, since these are often different.
If you have any hot water at all, or can shower at a neighbor's or gym for a day, it's usually worth getting a second quote rather than accepting the first same-day price out of urgency.
