Oh, forgot to mention, the new boiler is only consuming 400 gallons, where the old one used 900 gallons of propane.
If that trend continues, the new boiler will have paid for itself in a year and a half.
Now, that may be because I was seriously not running the old system right. But, I have talked to others around my area, and 2000 gallons a year isn't out of the question for most, so what I was getting last year, seems to be average for my area.
I also was wrong about the frost line. For footings, it's 42" to up to code, around me, the water pipes and sewers that aren't 6 feet down freeze if you don't have good snow cover in January.
I have a poorly updated blog about my house project located here:
