Are you somehow giving the measured efficiency or the rated one?
Anyone know if there is an innate difference in the efficiency of hot
air furnace vs. a hot water furnace?

What is a hot water furnace? Most houses using hydronic heating have
boilers.

Doesn't confuse me. Most "boilers" in residential heating don't come
very close to boiling.


Proper terminology. Furnaces heat air. Boilers heat water. If
everyone uses the proper terms, especially on a home repair group, it
avoids confusion.

There are some specialized units that use hot water to heat the air,
thus they are a hot water furnace, but the end product is heated air.
Water is just the heat source.
