in an airplane hanger?? Nice graphs. Makes you wonder what every one else's product curve would look like if you tested with returns that low.

Water at 140, 160 doesn't look anywhere near as impressive.

Mod/Cons

My theory is that condensing boilers are actually primarily modulating boilers designed to handle condensation. Condensing flue gasses helps, but the modulation is the important feature as I see things. It does appear to take quite a bit to make the KN condense.

Call me a skeptic

Iron...........Condensation........sounds like a very defined life cycle to me. I know, I know, I've read the logic behind the innovative use of iron in a condensing appliance but it just seems like........why. Efficiency isn't any better than a stainless boiler and it would seem that there would be less margin for error. But hey, what do I know. I'm sure that someone making a lot more dough than me designed it.
