Quite common to see them used where needed in better quality construction.
but for it to do any good, each
plumbing run would have to have one and it would require a pump to run
continuously.
Not necessarily. Some of them run by gravity ("thermosyphon"). Cold water is
heavier than hot. They work the same as the old "gravity" hydronic heating
systes.
Happy New Year,
