What Affects Your Water Heater Installation Cost in Keller
The final price depends on the unit type (standard tank vs. tankless), with tankless systems costing more due to higher equipment and labor. Adding a new gas line, if needed, runs $300–$1,000. Permit fees and inspection requirements add a modest amount. The age of your home may also affect labor if existing connections need updating. Choosing a heat pump water heater could qualify for the federal 25C tax credit (30%, up to $2,000), but Texas has not yet launched statewide rebate programs.
