That's amazing. I mean, I haven't seen/heard of a tanked hotwater heater in my country in decades, outside of increasingly infrequent rooftop solar heated tanks.

We've got instant gas, but I suppose most are electric now. Been running for decades with only needing to be adjusted between summer and winter temps sometimes.

Tanks are just... Useless. Takes up space with no benefit. Tanks use more power or gas. They fail more often (despite your personal experience).

If your tankless system is lasting less than 20 years, you're doing something wrong. If your tankless isn't giving steady water temp nonstop, you're doing something wrong. I mean, those are two of the main benefits they have over tanks. That, and cheaper to run.

Their only advantage is they're cheap to buy and cheap to install.

It's the cheap boots issue.

You save money up front and so you waste money long term.

Or, you buy good boots that last.
