Electric vs. Gas Water Heaters: Costs and Efficiency
Electric and gas water heaters can both deliver reliable hot water, but they often differ in upfront cost, day-to-day operating expenses, and overall efficiency. The “better” option depends largely on local energy prices (electricity vs. natural gas or propane), your household’s hot-water demand, and whether you’re replacing an existing unit or installing one for the first time.
Below is a practical comparison of cost and efficiency, along with common scenarios that tend to favor one fuel type over the other.
Efficiency: how much energy becomes hot water
Water heater efficiency is typically measured by how effectively the heater converts energy into usable heat. In broad terms, modern electric water heaters (including heat-pump models) can be highly efficient, while gas units vary depending on the type.
Conventional gas tank models often operate with lower efficien ... Read more »
