San Diego Water Heater Cost
Last verified: November 11, 2026
San Diego water heater cost depends mostly on the type you choose and the extra work your home needs, and this page shows both with every figure sourced. One local fact frames the choice: SDG&E delivers both electricity and natural gas here, through 1.49 million electric meters and 905,000 gas meters (SDG&E, accessed Nov 11, 2026), so gas versus electric is a choice between two services from the same utility.
Installed price ranges by type
