Water heater installation cost by job.
Installed-labor pricing for Wauwatosa, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Wauwatosa typically ranges from $800 to $1,800 for a standard tank unit and $1,800 to $4,600+ for a tankless system. With a median home age of 73 years, many homes may need updates to meet Wisconsin's plumbing code (SPS 382-387), which requires expansion tanks on closed systems.
