Water heater replacement cost by type.
Installed prices for National City, adjusted for local labor. Larger tanks and code upgrades move the number up.
In National City, California, where the median home was built in 1968, many water heaters are reaching the end of their lifespan. Replacing an aging unit is a common home improvement, with local installed prices ranging from $750–$1,900 for a tank gas heater, $850–$2,100 for tank electric, $1,450–$3,300+ for tankless, and $1,700–$3,800 for a heat pump model. Given California's moderate climate and the federal 25C tax credit (30%, up to $2,000) for heat pump units, many homeowners find a heat pump water heater a strong fit. However, local codes require permits, seismic strapping, and often an expansion tank, which adds to the cost. With a homeownership rate of only 30.7%, many residents rent, but homeowners should plan for these requirements.
