Decided this year to run mostly propane heat for our house. A 2644sq ft ranch with vaulted ceiling in the living room. Running furnace off a nest thermostat and sensors. Had the furnace at 68 in the day running off a sensor in the living room and at night off a sensor in the master bedroom at 65. We have a 330 gallon propane tank and we were filling up every 4-5 weeks mostly 4 since winter dug in. So 165-200 gallons every 4 weeks. Is this sound about normal for usage for propane?
 
There's about 92000 BTU in one gallon of LP,
so your furnace will burn a gallon in 1.15 hours,
for every hour that it's burning. (92/80)
