The standards on residential water heater efficiency, which are required by Congress, have not been updated in 13 years. Water heating is responsible for roughly 13% of both annual residential energy use and consumer utility costs, the DOE said.

    I doubt the energy savings would cover the cost difference in my case, and even if it did it’s worth a little extra to never run out of hot water.

    I’ll stick with the tankless.

      its somewhere like 3x more efficient, and for environmental standards, I’m sorry but your personal preference shouldn’t really matter. 3x is 3x

        Storage water heaters can also capture off peak or curtailed energy (acting as 6-12kWh of diurnal storage), so they are more than 3x better in terms of emissions.
