I’ve lived here my whole life , when I was younger my family was extremely poor, and I don’t ever remember us filling our tank completely. One day our cement pad under the tank was no longer up to code and we could no longer get deliveries at all of any size, even if we scraped up enough for the 100+ gallon minimum.

If we did buy kerosene, we filled up 5 gallon canisters at the store and hand poured it in, usually 20 gallons at a time. When that wasn’t an option, we invested in a space heater, and it amazing and kept our living room at a livable temperature. Yes, it’s very inconvenient that it’s one room, but during cold snaps it is a savior. If you can’t get fuel assistance , I do recommend a space heater, but never ever leave it on when you aren’t home. Best of luck!
