Expect a propane-powered generator to burn 2-3 gallons an hour. A 500-gallon tank will power your home continuously for a week.

Besides, do Generac generators use a lot of propane?

As for another example, again depending on what you are powering and the size of your generator (let's say 20kw in this example), a propane generator may use around 2-3 gallons/hour. So, if you have a 500-gallon tank, which can only be filled to 400 gallons, then a full tank would last you around 6 to 7 days.

So anyway, how much propane does a 22kw Generac use? For example, according to Generac a 22 kilowatt generator would burn approximately 2.1 gallons per hour at ½ load and 3.6 gph at full load, while a larger 38 kilowatt unit would burn 3 gallons per hour at ½ load and 5.4 gph at full load.

Really, how long will a 100 pound propane tank run a generator?
