I am almost done with a new master bedroom suite. I just got the gas turned on today for our new gas stove that is going to heat the new room. What a great feeling! Out all day clearing snow and now sitting by my new gas stove! Anyway, my question is. Never having LP gas before, how much or approx how long does a tank of LP gas last when using a gas stove? I have dual 100 lb tanks and the addition is on the second floor at the top of a staircase, so I am anticipating the stove will not be on excessively as a lot of heat rises up there naturally. I know this is almost impossible for anyone to give a even semi-accurate answer. So lets say if I ran the stove continuousy on medium setting, how long would you guess the gas would last? (not going to run cont, as I hooked it up to a thermostat) I am just trying to "gauge" how fast these things eat up gas. Side note, In case anyone is wondering why I installed a gas stove when the cost of gas has skyrocketed. reason is we have a all electric house that I heat with coal and didnt want to have to put wall to wall baseboard heat around the room and lose my wall space. Any opinions would be great.
