I have tankless point of use water heaters. I am �wondering how long
they last.

Like my gas tankless the coils are known to last 30 years, its just
finned copper pipe, there is no reason for them not to last as long as
home copper piping.

modern tankless with no pilot light, have complex flame sensors
igniters, and monitors.

once a part fails, if its no longer available you are stuck, plus the
heat exchangers can clog from sediment.

do not assume a tankless is forever, after all how many newer products
really last?
