Nobody else mentione this, so I thought I should. What you are
talking about is a potential BOMB! You absolutely must have
proper safety controls on it so the boiler cannot ever get
overheated. (I'm not sure how you do this on a wood-heated
boiler.) For gas or oil, you just cut the burner off if the
circulator pump quits. You might actually have to have some
sort of fire-putter-outer in case of electrical outage, pump
motor failure, etc. If the worst happens, you may have to just
let the water out, and melt the boiler.

Remember this thing is making hot water, not steam, nor is it new
technology. They were using hot water radiators in the grade school
when I was in the first grade for God's sake, and the school was an
old building even then.

You can control pressure in the boiler with a pressure relief valve,
just like they always have.

The only other controls you need are the chimney damper and the air
inlet doors to control the draft.

If you are worried about the make up water just mount a "make up" tank
above the boiler.
