Water heater installation cost by job.
Installed-labor pricing for San Angelo, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In San Angelo, Texas, water heater installation costs typically range from $800 to $1,750 for a standard tank unit and $1,750 to $4,400+ for a tankless system, plus $300–$1,000 for a new gas line if needed. With a median home built in 1976, many homes may require updates to meet current codes, such as an expansion tank on closed systems. Texas law requires a licensed plumber and a permit with inspection for replacement, so DIY installation is not allowed. The humid subtropical climate and moderate winter inlet water temperatures make a mixed unit type a practical choice. Federal tax credits (30% up to $2,000) apply for qualifying heat pump water heaters, but local utility rebates are limited.
