Higher pressure = better atomization of the fuel and therefore better efficiency and lower emissions (typically).
a B10-5 section with net IBR of 108k btu's would be too large a boiler for this application, correct?
the 2 supply houses tell me the B10-4 wouldnt keep up, are they that desperate for $100 more?
No they're not looking for the $100, they don't want the "I'm cold" phone call. A larger boiler never guarantees that anyway.
I'd suggest rolling with the B-10/4, it's not about the $100
Got it, thanks man~
will post pics of this project when i get it done
thnx to all for all the sound advice!
Looking forward to it, let us know how it turns out. Most important is a year from now with the fuel savings data.
