in the first post....

So tell me, why so keyed up on work related issues on a Sunday and on Christmas Eve no less? :)

Take a break! Be good to yourself.

As The Harvard Rule of Arts and Sciences says:

"Under the most stringently controlled conditions of temperature, pressure, humidity and other variables, the organism will do as it damned well pleases."

Would a steam coil and hot water coil be the same size if 212 degree water were used in the hot water coil? I would think the steam coil would be smaller as the latent heat (960 Btu's) would be a factor. Our engineer tells me that is not the case. He says 212 degrees is 212 degrees and that is all that counts. He also says that a steam coil with a trap that has failed open will put out the same amount of heat as one with a properly operating trap.

What is more confusing is why on a 90 plus condensing boiler do you have to measure the output condesate to get a accurate measument of the heat output in order to account fot the 960 btu extra output that cannot be measured with a stack temp reading.
