Wet base gas steam boiler sizing and suggestions
When looking at the spec sheets of wet base oil boilers and
planning to use a gas gun, is the I=B=R sq. ft. steam the same with a gas gun
or does the boiler need to be up-sized to produce the same output?
Which gas gun is best to use with the Slant/Fin Intrepid series? I tried in a
past year to get a G-8, but it was difficult and didn't happen.
I'm uncertain of the convector EDR numbers for my exact convectors. How should
I error on the boiler sizing? I'm at about 756 sq. ft. of steam. How much
efficiency do I lose when up-sizing or can I adjust some with the gas gun?
In comparing atmospheric to wet base it seems to be only a ~2 (EI)-4(no EI)% difference. Here, I read 6-7%. I'm trying to make sure wet base is worth the trouble and expense.
Anyone know of a good person to do this job in the NYC area. This is residential, single pipe steam. The current boiler is original from about 1920.
