there's probably not a lot of room for a greywater heat exchanger either.
the one gary reysa and i are working on would be about 3' diameter x 6' tall,
with the greywater i/o near the top. if the 4" x 100' black corrugated
drainpipe spiral were flat (eg hung under a basement ceiling), it would be
about 7' in diameter.

that could increase the capacity with good final temperature regulation,
compared to putting the tankless after the tank :-)
