All that, PLUS you can't get 140 degree water out of them in the winter.

tankless are a bad idea for most people, they have so many trade offs
and by the time you pay for the install its a loser.

Talkin stupid again, mine is 8 yrs old, it paid for itself in 4, to
bad you couldnt afford one or even a new condensing unit on your
recent replacement. So you still have an inefficent new junk unit.

high initial install costs, needing LARGE gas supply line, possibly a
upgraded flue, typical gas hot water tanks about 40K BTU tankless to
supply a comparable sized family over 100,000 BTUs. delay when turning
on hot water till burner gets going, waste of water and sewer...
tricle uses oif water may result in cold water, theres a minimum flow
to activate burner. current tankless with no pilot are as or more
complex as a 96% efficent furnace requiring perodic pro service and
possible flushing of sediment from heat exchanger. many tankless
require line voltage to operate. power failure means noi hot water at
all.

the federal government cost comparison website says tankless save
little money because of high upfront costs.
