I've had this setup for many years and never understood why it is set up this way. I get "heat ghosting" on the cold water supply side. interested in hearing thoughts about it.
Thanks

    You might could benefit from a "heat trap" on the cold side (or even on both sides), but the experts will know for sure.

    I am trying to understand your piping. There are several ideas that are good and others that make no sense when you have this situation. You have a tankless coil and a separate water heater. Are they piped together or is the tankless coil abandoned?

    There is another problem with your wood stove boiler and using the boiler circulator. If the water temperature is below the minimum DHW temperature, the control stops the circulator in order to offer priority to the DHW. You clearly do not need that and should have a comprehensive rewiring of the controls to save on oil and optimize the wood fuel for both heat and DHW.

    After you make that expensive repair and you still have the same problem, What will you check next?

    It’s not abandoned, but not sure it’s plumbed correctly.

    So your photographs are not easy to follow the piping design, since all the pipes are covered with dark insulation. Perhaps you cold draw a diagram of the piping. show all the components in question. Show the heating pipes in green. Show the hot water pipes in red and the cold water pipes in blue. Something like this
    You can draw on paper if easier
