There are 2 advantages only, one is space saving. They can be hung on
the wall and do not take up floor space, next is you do not have to
heat the water stored in the tank. They are much more efficient.
Unless you want to rewire, repipe, and reflue your entire house, they
will still be placed in a central location and 1 unit will feed the
entire house/building. No matter what, you will still have the heat
loss in the standing water in the pipes, just no heat loss from water
stored in the tank. Basicly you will just heat the water to be used,
thus the savings.

Been there, done that.....

I would think that a big reason for putting in a tankless heater is that
it
is smaller and therefore capable of
bieng installed closer to the long run sink and thus giving less warmup
time/loss.
and thus is a convenience even more than an energy saving.

Keep the potential noise problem in mind. The tankless heater probably
requires a forced air vent. Also, they can't be installed just anywhere in
the house since they need air, exhaust and a gas supply or heavy-duty
electric service plus the plumbing.

I'm living in a new house with two forced air tank type gas water heaters.
The one in the laundry area is fine; but the one in a small utility closet
next to the upstairs bathroom lets you know when it's running. The fan
noise doesn't make it through the bedroom walls thanks to good insulation.
Yes, I avoided a 50 foot hot water pipe run and long waits to get hot water,
but the noise is more than I expected.
