Water heaters in El Cajon homes
Utility gas heats 51%, below the California figure of 62% of homes. That ranks 9th lowest of the 151 California cities we profile. Water heaters usually use the same fuel as the furnace, which decides venting and gas line work on a replacement.
With 59% 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.
