Water heater replacement cost by type.
Installed prices for Gilroy, adjusted for local labor. Larger tanks and code upgrades move the number up.
In Gilroy, where the median home was built in 1990, many water heaters are reaching the end of their 10-15 year lifespan. Replacing a unit involves local permitting, seismic strapping per California law, and an expansion tank if your plumbing system is closed. With mild Mediterranean winters and moderate inlet water temperatures, 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. Typical installed prices range from $900–$2,200 for a tank gas model, $1,000–$2,400 for tank electric, $1,650–$3,900+ for tankless, and $2,000–$4,400 for a heat pump unit.
