We have a buried 500 gallon propane tank in the backyard. Only used for heat.
We on average use half the tank in a winter season… this year will be a bit more. Hard to complains about heating a 2900 square foot house on a little more than 200 gallons of propane.
I always top the tank off in the spring, but I may be rolling the dice this year, and hope prices fall back a little towards the fall. I know if I fill it in the next month I’m going to be lying an arm and a leg
