In the Villages, the tankless heater is outside, where it starts quite hot already from the sun heating it for free. Plus any leaks do not flood the house.
Tankless water heaters can be 24%-34% more efficient for households using 41 gallons of hot water or less daily, and 8%-14% more efficient for those using around 86 gallons daily.

Tankless water heaters are fine if they are installed with a new house. But, the question was about replacing an electric tank type water heater with a tankless heater (Post No. 19). Usually, this does not make sense, especially for an all-electric house. The house electrical system was not designed to accomodate an electric tankless water heater. So, you need to hire an electrician as to install a new high amp circuit and to run it to the water heater location. And, sometimes, the electrical panel will not even accommodate the high amp circuit breaker, so you need to upgrade the panel. In most cases, it makes more sense to just replace the existing tank type water heater with another tank type unit.
