Water heater installation cost by job.
Installed-labor pricing for San Juan, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In San Juan, Texas, where the median home was built around 2001, many homeowners are considering water heater replacement as units approach 20 years old. Typical installed costs for a standard tank water heater range from $750 to $1,650, while tankless installations run $1,650 to $4,100 or more, depending on gas line work. Texas law requires a licensed plumber and a permit with inspection for any water heater replacement—DIY installations are not permitted.

Local codes follow either UPC or IPC, and expansion tanks are required on closed systems.
