Water heater installation cost by job.
Installed-labor pricing for Mission, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Mission, Texas, water heater installation costs typically range from $750 to $1,700 for a standard tank unit and $1,700 to $4,200+ for a tankless system, plus $275 to $950 for a new gas line if needed. With a median home age of 27 years, many homes may require updates to meet current code, including an expansion tank on closed systems. Texas law requires a licensed plumber and a permit with inspection for any water heater replacement, so DIY installation is not permitted. The humid subtropical climate and moderate winter inlet water temperatures make a standard tank or tankless water heater a suitable choice for most homes.

Gas Line Upgrades for Tankless Units
Tankless water heaters often require a larger gas line, adding $275–$950 to the project cost.
What to Expect During Installation
A licensed plumber will first obtain the required permit from the city. The job typically takes 4–8 hours, including removing the old unit, installing the new water heater, and connecting gas or electrical lines. After installation, the plumber will schedule an inspection to ensure code compliance.
