Clarification on steam boiler sizing
In sizing a steam boiler, I have calculated the EDR of all the radiators.This particular house has 58ft of 2" uninsulated main, which they dont want insulated for fear of freezing in the basement. The connected load also includes 110 ft of 1 1/4 runouts.
Should the load calculation include these piping losses, even before addition of any pickup factor?
The pickup factor in my understanding is to allow for the heating of the total load from a cold start, but this extra load is a continual load, no different than additional radiators or bare pipe used for space heating.
Where can I find equvalent EDR of 2"&1 1/4" bare iron pipe to add in the calculation.
I own all of the steam books available thru heatinghelp and cant find that particular info.
But let me take a minute to point out the quality of the books on the site. Some of the best refernce material for steam heat available. Worth every penny.
