I assume you mean 75K BTU
You need a boiler that outputs at least 75K.

0 is much to low. I will guess you can heat your home with 50k. Adjust your program to 14 deg outside temp. It is very rare it stays below this for more than a couple hours on the very coldest days of the year. Set indoor temp at the temp you feel comfortable.

ok, to be conservative i changed it to 10 degrees.
it went down to 65k btu
anybody have any ideas why the installer of my boiler (before my time) put in a 125k btu, and all the proposals i have gotten for a new one (three) have been for about 115k?
the slant/fin heat calc was very thorough.
am i falling into some novice misconception?
as a reality check, my house is
-1700 sq ft
-100 years old
-two-layer brick 1st and 2nd floor (uninsulated)
-frame third floor and attic (heavily insulated)
-double glazed windows
-kept at about 65* avg
-uses the boiler for DHW
thanks,
kodo
