Fuel type conversion: Switching from electric to gas or vice versa requires new gas lines or electrical circuits, adding $500–$1,500 to the project.
Code upgrades: Dallas building codes may require an expansion tank, updated gas connectors, or an upgraded drain pan. A licensed plumber handles these automatically.
Location: Water heaters in tight attic spaces or closets take longer to replace than those in a garage or utility room.
Brand and efficiency: Premium brands like Rinnai and Navien cost more upfront but offer longer warranties and better energy efficiency.
