Water heater replacement cost by type.
Installed prices for Alamo, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Alamo, California, where the median home was built in 1977 and household incomes are high, water heater replacement is a common upgrade. Local installed pricing ranges from $750–$1,850 for a tank gas unit, $850–$2,100 for tank electric, $1,400–$3,300+ for tankless, and $1,700–$3,700 for a heat pump model. Given Alamo's mild Mediterranean climate and moderate winter inlet water, a heat pump water heater is a strong fit, especially with the federal 25C tax credit covering 30% of the cost up to $2,000. Permits are required under the California Plumbing Code, and seismic strapping is mandatory per state law. Homeowners should expect to pay for an expansion tank if the system is closed.
