Water heater replacement cost by type.
Installed prices for Danville, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Danville, where the median home was built in 1979 and 84% of residents own their homes, water heater replacement is a common upgrade. With a median household income over $209,000, many homeowners choose heat pump water heaters to take advantage of the federal 25C tax credit (30% up to $2,000). Typical installed costs range from $800–$2,000 for a tank gas unit, $900–$2,200 for electric, $1,500–$3,500+ for tankless, and $1,800–$4,000 for a heat pump model. Danville's mild Mediterranean climate means moderate winter inlet water, so heat pumps operate efficiently year-round. All replacements must comply with the California Plumbing Code, including seismic strapping (per Health & Safety Code 19211) and an expansion tank if the system is closed. A permit is required for any water heater replacement in Danville.

Water Heater Replacement in Danville, explained.
What drives the cost in Danville?
The age of Danville’s homes (median 1979) often means older plumbing and gas lines that may need updating, adding to labor costs. Choosing a heat pump water heater qualifies for a 30% federal tax credit (up to $2,000), making it more affordable upfront despite a higher base price. Tankless units require gas line upgrades and venting, increasing installation complexity. Seismic strapping and expansion tank installation are code requirements that add $100–$300 to the total. Local permit fees also vary, typically $150–$300.
Common water heater issues in Danville
Sediment buildup

Seismic strapping compliance
California law requires strapping at the upper and lower third points; many older installations lack proper bracing and need retrofitting during replacement.
