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?
A 100-pound tank can run a 7-kilowatt generator for 66 hours, or a 12-kilowatt generator for 36 hours. In general, generators operate between 25-75% of their capacity, so the fuel supply may last longer. A 100-pound propane tank holds approximately 23.6 gallons.
How big of a propane tank do I need for a whole house generator?
For most home usages we recommend either a 120 gallon tank for short outages (1-2 days) or a 500 gallon tank for more extended time periods (8-10 days). Here are more exact estimates based on the size of your generator and assuming an average 50% load on the generator during the outage.

A gallon of propane contains 91,502 BTU of heat energy whilst the BTU rating for appliances is in BTU per hour, based on burner size. Dividing 91,502 by the BTU per hour rating gives you the number of hours that one gallon of propane will last.
On the Generac 5875 model, for liquid propane, on full load, 2.57 gallons/ hour are used according to the spec sheet.
Just like in your home, Generac's business standby generators can run on a propane fuel tank supply. Fuel tanks can provide up to 168 hours of run time before they need to be refilled.
A pound of propane has 21,591 btu. So if you had a 21,500 btu heater it would run basically 20 hours on a true 20lb bottle. With a 30,000 btu heater you multiply 21,500x20(pounds)=430,000 and divide by your heater size of 30,000btu. Which gives you 14.34 hours if you run it at full all the time.
On average, you can expect a gasoline-powered portable generator to run about 7.5 to 12 hours continuously, a propane-powered portable generator to run for up to 8 days if continually refueled, and a standby natural gas generator to run continuously for up to 3 weeks.
Propane weighs 4.24 lbs per gallon so 100 lb capacity tank would hold 23.6 gallons.
It's clean burning too, at least when compared with gasoline. On top of this, propane generators are typically much quieter than gas generators
, which make quite a racket. For an emergency preparedness
kit, propane is valuable because you can still acquire it when there's a major power outage.
Propane Generator A 20-kilowatt generator would burn about 3.45 gallons per hour. In the United States, the average price per gallon for propane is around $2.50, as of March 2018. The cost to run a portable generator for 24 hours would be consume about 83 gallons, costing over $200.
How long will a 250 gallon propane tank last? It lasts 3 months if we dont need heat and 2 weeks when we need the heat (if it's a little cold out).
1000-gallon propane tanks The minimum distance from the opening of a building is 10 feet. The minimum distance from any source of ignition is 10 feet. The minimum distance from a property line is 10 feet.
bottle usually contains about 5 gallons of propane. This means a 40lb. bottle should have 10 gallons of propane and the generator will run for about 20 hours at a 50% load.
A 2,000 square foot home in a mild climate would require about 2 million BTUs of propane, and cost $76 per month to heat. A home in a moderate climate would require 4.0 million BTUs, and cost $152 per month. And, a home in a severe climate would need around 6.5 million BTUs, and cost around $248 per month to heat.
Because of this, it's difficult to come up with the exact lifespan of 500 gallons of propane. That said, most 500-gallon tanks can keep the average home running for a month to a few months depending on the time of year and use.
