Let's be fair. The OP did say, the upstairs is heated with a heat pump. Being so large, it's likely relatively new, and reasonably insulated, plus, it's in Maryland. Cold, but not cold like the more northern parts of N America.
And, I just looked up a heat calculator, and his 1000 gallons of LP is about equal BTU wise to around 800 gallons of oil. 800 gallons is about the average use for a 2000sqft home in Maine. If you know the homes in Maine, they tend towards old and leaky. So, if he's got a newish, well-insulated, home with heat pump for upstairs, electric HW, etc., perhaps he is only using 1000 gallons of LP.
For comparison, my relatively new, well-insulated, triple-glazed 4000sqft home in Maine used only 700 gallons of oil last year. My new this year, avg size pellet stove, 47k btu, is heating the open-space, equal to 3000sqft. I use 1 and a half bags on a normal 40 degree-day winter day, aka avg 25 degrees. That's equal to about 4 gallons of oil. My point being, let's not crucify the OP since we don't know all the details of his mcmansion. 1000 gallons of LP is certainly possible in a well-insulated home, even if it's large.
All in all, I'd say, if you are paying only $1.80 a gallon for LP, just turn up the thermostat; however, if you are paying $2.80 or more, then you might want to consider a big pellet stove like a Harman P68 in the living space.
