Water heater installation cost by job.
Installed-labor pricing for Granbury, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Granbury, Texas, water heater installation costs typically range from $650 to $1,500 for a standard tank unit and $1,500 to $3,700+ for a tankless system, plus $250–$850 for a new gas line if needed. With a median home age of 24 years, many homes may need updates to meet current code, which requires a permit and inspection for all replacements. The local humid subtropical climate and moderate winter inlet temperatures make a mixed water heating approach suitable, though a heat pump unit could qualify for the federal 25C tax credit (30% up to $2,000). Labor costs reflect the need for a licensed plumber, as DIY installations are not permitted under Texas law.

Water Heater Installation in Granbury, explained.
What influences your installation cost?
In Granbury, the main price drivers are the unit type (tank vs. tankless), fuel source (gas line work adds $250–$850), and the need for code upgrades like an expansion tank on closed systems. Permit fees and inspection costs are included in most quotes. Older homes may require additional piping or venting modifications, which can raise the total. Local labor rates and the plumber's experience also affect pricing.
Common water heater installation issues in Granbury
Permit and inspection requirements
Texas law requires a licensed plumber to pull a permit and schedule an inspection for any water heater replacement. Skipping this step can lead to fines and issues when selling the home.
Expansion tank needed on closed systems
If your home has a closed water system (e.g., check valve or pressure-reducing valve), a thermal expansion tank is required by code to prevent pressure buildup.
Gas line capacity for tankless units
Upgrading to a tankless water heater often requires a larger gas line to supply sufficient BTUs. This can add $250–$850 to the installation cost.
