Water heater installation cost by job.
Installed-labor pricing for Danville, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Danville, CA, a typical water heater installation costs between $800 and $1,800 for a standard tank unit, and $1,800 to $4,600+ for a tankless model. These prices reflect local labor rates, required permits, and compliance with the California Plumbing Code. Because most Danville homes were built around 1979, many need seismic strapping and an expansion tank, adding $100–$300 to the job. The mild Mediterranean climate means winter inlet water is moderate, so a heat-pump water heater is a strong fit for energy savings, and the federal 25C tax credit (30%, up to $2,000) applies.
