Water heaters in Fairfax homes
Utility gas heats 54%, above the Virginia figure of 32% of homes. That ranks 11th highest of the 35 Virginia cities we profile. Water heaters usually use the same fuel as the furnace, which decides venting and gas line work on a replacement.
With 38% of homes built before 1980, many water heaters sit in tight basements or closets that were sized for smaller tanks, so measure before ordering a replacement.
In Virginia: Older homes in Northern Virginia, Richmond and Hampton Roads have galvanized lines and cast iron drains.
