Seasonal timing
First frost usually arrives around October 25, later than most of the region, and that date is a reasonable marker for having the boiler and its hot-water priority checked together.

On a combined system the boiler splits its output between space heat and the indirect tank. If the priority control isn't switching properly, both suffer, and a technician can verify the sequence rather than assume the tank is undersized.
It does. The internal coil scales over time and the anode rod depletes, both of which a technician checks during a normal service call.
No. Air in the loop, a closed balancing valve or a failed circulator all produce the same symptom, and a technician is the right person to open and purge a loop rather than a homeowner working on live piping.
Newer installs run lower water temperatures and modulate output, while a 1970s boiler tends to fire flat out and cycle. That difference shows up in comfort as much as in fuel use.
