Water heater replacement cost by type.
Installed prices for Los Gatos, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Los Gatos, where the median home was built in 1971, water heater replacement often involves updating older systems to meet current California codes. Typical installed costs range from $800–$2,000 for a tank gas unit, $900–$2,200 for tank electric, $1,500–$3,500+ for tankless, and $1,800–$4,000 for a heat pump model.

Permits are required, and seismic strapping (at upper and lower one-third points) is mandatory under state law. Expansion tanks are needed on closed plumbing systems per the California Plumbing Code.

Seismic strapping compliance
