I 've read a little bit of it, and it echoes some of the ideas I've been using over the past ten years. Know your system water temps at typical winter day loads and peak loads, size your lead condensing boiler(s) for the typical day load at condensing temps, and fill out the rest with conventional boilers. This spring was the first time I installed a hot water boiler over 280,000 input, it was those 3 staged 396,000 input Burnhams.
When going from single input, usually oversized boiler, to staged residential size boilers with good controls in churches(most of my com. wokr) I can virtually guarantee a minimum fule usage reductin of 40% and have seen around 60 to 70%.

When going from single input, usually oversized boiler, to staged residential size (noncondesing) boilers with good controls in churches(most of my com. work) I can virtually guarantee a minimum fuel usage reduction of 40% and have seen around 60 to 70%.

I'll have to read the rest tonight.

Thanks for coming up with the good stuff
