I saw a few side comments about this issue, but would like to explore it in more detail.

Makes a case for using a HWH as the sole source for DHW as well as for radiant heating.
FWIW, I would be considering an open system (unless there was a compelling reason not to -- just starting to learn about radiant), with an over-joist flooring. The 1200 sq. ft. house has wood floors, is somewhat insulated (brought "to code" via our utility's insulation subsidy program), and is located in the Pacific NW near Puget Sound (it rarely gets extremely cold here).
Our HWH is probably dying. It is no spring chicken, and I want to be prepared with a choice for a replacement HWH if the nipple breaks off when attempting to replace a dip tube that is broken.
Anyway, thoughts about HWH vs. boiler, especially considering that link above, are appreciated.
