Calculating heat loss based on average winter fuel oil consumption: I am starting to look into Geo, and I'm trying to

I am starting to look into Geo, and I'm trying to sanity check the size of the system for Heating purposes, based on present fuel oil average usage. For reference, my pre-build room-by-room radiant heat load total was computed at approx. 35k BTUs based on a 6 degree F. outside temp., and if basement zone is added in (currently it is not hooked up), then add another 15k for a total of 50k-55k BTUs/HR (paper world). Here's how I did my calculation, please let me know if this approach is sound and also a reasonable way to sanity check paper calcs. My assumption here is that average fuel consumption per hour equates to a number of BTUs/hour, which is the heat loss. I observedusage of 150 gal per month during Dec 2010-Mar 2011, = approx. 5 gallons per day. Foroil-based systems, each gallon of fuel oil contains 139,000 BTU of energy. Myboiler has an 0.85 AFUE (efficiency) rating...
