How Long Does Water Heater Installation Really Take
Homeowners often picture installation as a quick swap, old tank out, new tank in. The reality involves a few more steps, and knowing them ahead of time helps you plan your day.
Standard Tank Swap: 2 to 4 Hours
A straightforward same size, same fuel type replacement in a closet or garage typically takes 2 to 4 hours, including draining and removing the old unit, setting the new one, connecting water lines, and testing for leaks.
Attic Installations Take Longer
Common throughout Houston, attic installs add time for safe access, maneuvering the tank through tight spaces, and confirming the drain pan and overflow line meet current code. Plan on 4 to 6 hours for an attic swap.
Switching Fuel Type or Adding a Gas Line Adds a Day
Going from electric to gas, or running a new gas line where none existed, usually requires a permit and city inspection, which can push the full project across two visits rather than one, even though the actual hands on work might only take a few extra hours.
