What Kind of Fuel Does a Whole House Generator Use?

what kind of fuel does a whole house generator use

Whole house generators are a great investment that can save you from losing power during a major emergency. They provide enough power to run all of your essential appliances, like air conditioners and furnaces.

There are many different kinds of fuel you can use to power your generator, including natural gas, liquid propane and diesel. Knowing what kind of fuel your generator uses can make a big difference in your preparations.

Natural Gas

The fuel your whole house generator uses is one of the most important factors to consider. Choosing the right fuel type will help you to decide which generator is best for your needs and will help ensure you have reliable power when you need it most.

Natural gas is a fossil fuel that’s formed when organic materials, like plant matter, decompose in the absence of oxygen. This creates methane (CH4) and other higher alkanes, including ethane, propane, butane, and pentane.

Chemically, natural gas is mostly methane with small amounts of other hydrocarbons and trace gases such as carbon dioxide, nitrogen, hydrogen sulfide, and helium.

Natural gas is widely available throughout most of the United States and is the cleanest burning conventional fuel, releasing far less greenhouse gas than oil and coal. It’s also a cost-effective and versatile source of energy that can be used to fuel homes, businesses and electric power plants.

Liquid Propane

If you live in an area where natural gas is available, you can connect a whole house generator to your home’s existing gas line or set up a gas line for the generator. This will give you the convenience of a constant supply and avoid any issues with power outages.

The fuel that your standby whole house generator uses is very important to its performance. Different types of fuel have different BTU levels and will produce different amounts of energy for the engine to generate.

Propane is a clean-burning fuel that can be stored in tanks ranging in capacity from 20 pounds to thousands of gallons. It is the most common fuel used in home backup generators because it provides a clean, unlimited source of heat.


When it comes to whole house generators, there are many different fuel options you can choose from. These include natural gas, liquid propane, and diesel.

When deciding which fuel is best for your home, it is important to consider a variety of factors such as where you live, how often the power goes out, and what you want to use the generator for. You also need to decide how much power you need and what your budget is.

Generally, a whole house diesel generator can be very cost-effective as they are one of the most efficient of all generators. They can reach peak performance in a shorter amount of time than other fuels and require less maintenance and replacement costs as well.

In addition, they are the safest fuel option as they are one of the least flammable and can be stored for up to 18 months. They are also easy to find and readily available at most gas stations.

If you have a whole house generator, you’ll need to know what kind of fuel it uses to power the equipment that comes with it. This is an important question to consider because different types of fuel have their own benefits and drawbacks.

In most cases, the fuel type you select depends on the location where your generator will be located and the amount of fuel you’ll need for the length of time you plan to use it. You may also need to consider your HOA restrictions and building codes if you live in a neighborhood where they’re required.

For example, natural gas is one of the most convenient fuels available. But, it can also be problematic if the gas lines in your home are damaged. This can prevent your generator from being supplied with fuel when needed.
