Water heater installation cost by job.
Installed-labor pricing for Denton, adjusted for local rates. Relocations and gas-line upgrades add to the base.
Water heater installation in Denton, Texas typically costs between $900 and $2,000 for a standard tank unit, and $2,000 to $5,100+ for a tankless system. Denton's median home was built in 1992, so many homes may need updates to gas lines or venting. Texas law requires a licensed plumber and a permit for water heater replacement, and expansion tanks are required on closed systems. With hot summers and moderate winter inlet water, a mixed-climate unit is recommended. The federal 25C tax credit offers 30% back (up to $2,000) for qualifying heat pump water heaters, but Texas has not launched state rebates as of mid-2026.
