: We have a boiler running at 75% eff. and are concidering a boiler that runs at 84% eff. Would this shopw up at the gas bill as a 10% savings?

Unless you've got an accurate steam meter (rare - most places won't spend the money on them) on these boilers, it'll be really hard to tell what's happening. Process loads & conditions can change, and building heating is affected by degree days, sun load, etc. Is there anything actually WRONG with the older boiler? Is it worn out? If it's just a case of a unit with a few years on it, you could likely get a good payback on doing some burner & control work on the boiler itself, and going over the distribution system and points of use. I've seen plants where they could have spent 10% of what they laid out on a new boiler to solve their problems.
