How long will 5 - 10 gallons of heating oil last me if I'm only using it for the hot water in my apt?

Question

I just ran out of oil in my apartment, which I didn't realize ran the hot water heater. I cannot afford to get oil delivered until friday, but really would like to have hot water before then. I can purchase 5 or 10 gallons of heating oil from the gas station down the street, but want to be sure it will last me until at least friday. I'm not using anything else that burns oil, only the hot water heater. Any ideas? Approximations?

Answer 1

I don't think it will last that long because your pilot light runs on this too and it stays on all the time. My guess is just the innitial fire up of the heater uses quite a bit of fuel. I'd say you'd be lucky to get through til thursday.
