Sounds like another satisfied tankless customer.

There's nothing wrong with tankless as long as they are sized for the
application.


I'd say even if they're sized right, the fact that in most cases
you'll never recover the increased upfront costs of the unit
and installation are something that's wrong with them. That cost
can include running a larger gas service. The OP might run into
that if he tries to put in a larger one. And the alleged savings
in operating costs, I think in many cases are overstated.




As with most things, people buy the wrong thing then complain about the
item as a whole. "Those things don't work" instead of "I got the wrong
model".

A tankless heater designed for a single faucet isn't going to perform well
for an entire house.

I don't and won't have one, for a variety of reasons, starting
with cost.

I looked at tankless models when we built our house. We didn't have gas
available and electric models would have required major electrical supply
upgrades. We have relatively cold well water so we would have needed a
large model. And, as you say, they're kind of expensive.

There you go.


However, I have used tankless heaters at many cabins and cottages and they
perform very well when sized correctly. Best part is the hot water never
runs out.


That is an advantage. How much it matters, depends on your situation.
For me, running out is not a problem with my tank type. On the flip
side, when my power goes out, I still have hot water, while with most
tankless, you don't.
