Full services directory How it worksFor prosAbout Get matched Call (866) 582-8523The most common water heater questions come down to five: what it costs (tank $600-$2,500 installed, tankless $1,400-$3,900, per NerdWallet), how long it lasts (roughly 10-15 years for a tank, about 20 for tankless), whether tankless pays back, whether a permit is needed, and what to do about gas safety.
This page collects the questions homeowners actually ask before spending money on a water heater. The short version of all of them: age and leak location decide repair versus replace, first hour rating decides sizing, and gas work decides who is allowed to touch it.
One theme runs through the honest answers: the pressure to upgrade is usually stronger than the case for upgrading. Tankless and heat pump units are genuinely better in specific situations. They are not universally better, and an emergency replacement is the worst moment to be sold one.
Where an answer depends on your address — permits, licensing, rebates, code requirements — we point you at the office that can actually tell you, rather than guessing. That is not evasion; a national answer to a local question is worse than no answer.
