Furnace and BTU Calculations

[rudolf]

i think it was on this board but i'm not sure, that a couple of links were posted for sites where one could calculate the size of a heating unit in BTU's. the site i remember had lots of fields that you could alter for door sizes, insulation values, etc. it could have even been an excel spread sheet.

at any rate if you know of that site/program or another one of similar ilk i would appreciate a reminder of where it can be found. i tried searching the archives but came up blank .
