Natural gas generators have been around for a while, but they are just now becoming more popular.
Natural gas is cheaper than electricity and propane, so it’s no wonder that natural gas generators are starting to become the go-to source of power for people with an electric or propane generator.
In this article, we will discuss the best natural gas generator for whole house use.
Here’s a sneak peek of the top 3 natural generators reviwed in detail below.
Types of Natural Gas Generators for Whole House
There are two types of natural gas generators: engine-driven and stationary.
1. Stationary Generators
Use a combustion process to produce electricity the same way as an internal combustion engine does. This is usually done with diesel fuel, propane, and gasoline.
These types of generators do not need any outside source of power since they are self-contained.
A natural gas generator will run at a constant speed, but some models can be adjusted to produce more power when needed.
2. Engine-driven Generators
Use an engine to drive the generator head or alternator directly.
This is the most common type of natural gas generator used for home backup power because they are cheaper and easier to maintain.
The size of the generator can vary from 20 to 200 kilowatt (kW), and larger models are available for commercial use.
These generators need a constant supply of fuel, but there is an option to shut off the engine when not in use if needed.
Some natural gas generators come with gasoline or diesel engines as a backup power source when the natural gas supply is cut off.
This allows you to keep all appliances and electronics plugged in as long as your generator has a fuel source.
Natural gas generators can also include an LP (propane) backup system. If you need to switch from natural gas to propane, flip a few switches and continue using your generator as usual.
Stationary Versus Engine-driven
The main difference between stationary and engine-driven is that the latter needs gasoline or diesel constantly while the former has a self-contained system.
This means that stationary generators are more expensive, but they do not need any outside power source, which is great if you’re off the grid or your electricity gets cut off often.
Engine-driven models are cheaper and easier to maintain since there’s no engine inside them.
Sizing a Whole House Natural Gas Generator
Since generators produce electricity directly, you will need an electrician to help size the generator and wire everything in.
Suppose your home uses natural gas for heating or hot water, it’s a good idea to add that into your calculations, since all appliances using natural gas draw power from the generator when needed.
A typical house needs between 30 and 100 kilowatts (kW) of power, but it depends on appliances.
If you want to run your whole house with a natural gas generator, then make sure there’s enough fuel storage capacity for at least 30 days if needed.
If you’re running an engine-driven model as most people do, keep in mind that they need regular maintenance and servicing to keep them running smoothly.
Natural gas generators are a good option for home backup power if you live in an area with regular utility issues or lots of natural disasters.
They run on cheaper fuel than gasoline, propane, or diesel. They’re easy to maintain as long as there’s a constant fuel supply,
but stationary models are more expensive and need a professional to install them.

What to Look for When Buying a Natural Gas Generator?
When you’re looking for a whole house natural gas generator, there are several things to consider before making your purchase.
Make sure you have enough room for the generator in your garage or outside. The best spot is near a window that can be opened to allow fumes from the unit to escape without letting any air inside
2. Fuel Type
Gasoline and propane are both popular choices, but gasoline requires more maintenance, so it’s better if you go with gas unless you prefer to deal with more upkeep.
The heavier, the better when it comes to whole house natural gas generators since this means there’s a more prominent engine inside which can power up your home during an outage for more extended periods.
Depending on your needs, you may want to purchase a unit that comes with an excellent warranty for parts and labor or one that’s covered by a lifetime limited warranty on the generator itself.
This will give you some peace of mind when using it in case something goes wrong over time.
