Water heater installation cost by job.
Installed-labor pricing for Foster City, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Foster City, a typical water heater installation ranges from $800 to $1,800 for a standard tank unit, while tankless installations run $1,800 to $4,600 or more, plus $300 to $1,000 for a new gas line. Because the median home was built in 1976, many homes have older plumbing and gas lines that may need upgrades. California requires permits, seismic strapping, and often an expansion tank, which adds to the cost. Given Foster City's mild climate and mostly gas water heating, a heat-pump water heater is recommended for energy savings, and the federal 25C tax credit (30%, up to $2,000) can offset the higher upfront cost.
