The prices for heating oil and propane being equal (they currently are in my area of NYS–about $1.45 per gallon on avg.), which is cheaper for home use on an annual basis?
I’m building a superinsulated house that will have hydronic radiant floor heat (so no forced-air furnaces … we’re talking a boiler or a water heater). Oil has more BTUs per gallon … but do the heating units consume that as efficiently as propane units? Will I end up using more gallons of oil in the winter or more gallons of propane?
