A tankless water heater is a drop in replacement for a traditional water heater.

Your contractor messes with it for a day and that evening you are taking a warm shower just like you did the night before.

This is what drop in means.

But if you were to go around selling people this drop in tankless water heater 150 years ago before homes had the required electricity, you would rightfully be called a liar.
