Another plus is that tankless water heaters are supposed to be one of the longest lasting appliances - 20 years.

I've never had a modern style tankless.
When we lived off base in Japan ~1983, we had a tank for heating oil, and the water heater used that oil and was "instant". You could take a shower forever and the water never got cold and it was HOT. I loved it and would be happy to have one again.

Our current electric water heater needs to be replaced. I suspect the bottom is full of sediment and the whole thing is probably coated with minerals from our hard water.
