That's a common myth. How do I know? My whole house electricity monitor checks the usage 86.4 million times a day. I have used my Wi-Fi monitor to check exactly how much it costs to keep water hot in an empty house vice an occupied one.
Think about it for a moment, it costs the same to heat water no matter what, the only energy a tankless saves is standby loss. An average couple will uses 13.00 to 16.00 per month for a tanked heater. Standby losses run about 2.00 a month.
Edit to clarify: Obviously I speak of an electric home.
For a gas home, where natural gas is almost completely consumed by the hwh, a tankless makes no economic sense at all. The meter fees for the gas line far exceed the total consumption costs for a tanked or tankless heater. Sure, if you have a gas heater pool or just like gas then cost isn't relevant.
