The fix: GO TANKLESS Although tankless and tank-style water heaters both operate at roughly 82% thermal efficiency when their burners are on, tank-style water heaters lose so much heat during standby mode that their actual efficiency averages 63%. If you install a tankiess model and use the same number of gallons of hot water, you could save that 19% difference. But here's the catch: Because there's no threat of running out of hot water with a tankiess heater, some people who've installed them start using more hot water, wiping out any savings. Used with restraint, however, tankiess models can be more efficient than tank-style water heaters and save money.
