Which is better for your home backup generator? Propane or natural gas?

Jul 15, 2022

When it comes to choosing a backup generator for your home, there are a few things you need to consider. One of the most important factors is what type of fuel the generator uses – generators can use either propane or natural gas. Both fuels have benefits and drawbacks, so which one is right for you? Here’s a look at the pros and cons of each fuel source.

Generac home generators run on either propane or natural gas. Propane has an advantage in energy density but usually costs more than natural gas. The cost of natural gas is about 40 percent of propane’s cost, which makes it the cheaper fuel for your generator. However, in many areas, natural gas is not an option or the cost of upgrading service to accommodate demand limits its appeal. Generac generators are designed to switch automatically between propane and natural gas, so you can use whichever fuel is more readily available or cost-effective at the time.

What lasts longer propane or gas generator?

Generac home standby generators are one of the most popular types of backup generators on the market. They’re reliable, efficient, and easy to use. But what kind of fuel do they use? Generac generators can run on either propane or natural gas. But which is better?

Propane has a number of advantages over natural gas. First, it’s more energy-dense, which means that in the same time period, you’ll burn more than twice as much natural gas as you would propane. That’s not to say propane costs less than natural gas. It costs more. But if running out of fuel is a concern, propane is a better choice because it will last you longer.

Second, propane is a cleaner-burning fuel than natural gas. This means that it produces fewer emissions, which is better for both the environment and your generator.

Finally, propane is easier to store than natural gas. It can be stored in storage tanks, making it easy to keep on hand in case of an emergency.

Overall, propane has many advantages over natural gas as a fuel for Generac generators. If you’re looking for a clean-burning, efficient, and easy.

Do Generac generators that run on propane also run on natural gas?

Generac home standby generators are designed to run on one fuel source. They are factory set to run on natural gas, however; at the time of installation it can be converted to propane much like a home gas stove. Generators that run on propane also tend to be little more expensive than those that run on natural gas, so it is important to consider your budget when deciding which fuel source to use. Generac generators are a great option for those who want the peace of mind of knowing their generator will work in the event of a power outage.

How long will Generac generators run on propane?

Generac home standby generators are one of the most popular choices on the market, and for good reason. They’re reliable, affordable, and easy to use. But one of the most common questions we get is, “How long will my Generac generator run on propane?” The answer, of course, depends on a number of factors, including the size of the generator and the specific model.

However, in general, a Generac generator will burn through around 2 to 3 gallons of propane an hour. So if you have a 1,000-gallon tank, you can expect your generator to run for around two weeks during an outage. Of course, this is just a general estimate, and your mileage may vary. For more specific advice, we recommend consulting your Generac dealer or authorized service provider.
