Water heater installation cost by job.
Installed-labor pricing for Huntsville, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Huntsville, AL, water heater installation costs typically range from $900 to $2,000 for a standard tank unit and $2,000 to $5,000+ for a tankless system. With a median home built in 1983, many homes may need updates to meet current code, including expansion tanks on closed systems.
