Hi, I am trying to get an idea of reasonable propane usage. Normally we heat the house mostly with wood from our property, but we ran out of wood a little early this year and have been using the central heat more. Otherwise the propane is used for the stove/oven and hot water heater. The house is apx 3500 sq feet. Being a little short on cash and propane prices being high in the cold months, I got a delivery of 100 gallons of propane thinking that would last about 8 weeks. That was three weeks ago and our propane tank is now empty! I was shocked! Granted, I have never used the propane much for heating like I have been, but 100 gallons in three weeks!?!?! My husband thinks we have a leak, I suspect we may really be using that much to heat the house but I wanted to see what others are using?
