Water heater replacement cost by type.
Installed prices for San Ramon, adjusted for local labor. Larger tanks and code upgrades move the number up.
In San Ramon, where the median home was built in 1993, many water heaters are reaching the end of their 10-15 year lifespan. With a Mediterranean climate and moderate winter inlet water temperatures, tank and tankless units perform well, but heat pump water heaters are increasingly recommended for energy savings. Local installed prices for a standard tank gas replacement range from $900 to $2,200, while tankless models run $1,650 to $3,900 or more. Permits are required, and California law mandates seismic strapping and often an expansion tank on closed systems, adding to the overall cost.
