1 An electric water heater can cost $400-$3,000 or more for complete installation of a conventional storage-tank model and $1,800-$4,500 or more for a tankless model (including a 220V/240V outlet). 2  Electric water heaters typically cost less than gas units but are more expensive to operate.
It calculated average one-time costs (purchase plus installation) and annual operating costs based on average utility rates for both types. The installation estimates: $865 for a 50-gallon storage-tank heater and $1,470 to $2,500 for a gas-fueled, tankless water heater.To see how a tankless investment might pay off, take the median, or $2,000, as the average installed cost, plus a few hundred more to disconnect and remove the existing conventional tank.ost homes have a storage tank for hot water â 50 gallons or more that's regularly reheated and ready to use 24 hours a day. The compact alternative, often billed as the more efficient European system, is a tankless, or on-demand water heater.
