Best Dual Fuel Generators Buying Guide
Buying a generator is not as easy as it sounds. There are so many options available, and so many things that you need to consider to ensure you buy the option that is best for you.
But there’s no need to worry because we’ve put together this handy buyer’s guide which is full of all the information you need to know about dual fuel generators.
The products we’ve looked at in this guide are some of the best available, but if you want to find out more before making a purchase, you’re in the right place.
Why buy a dual fuel generator?
You might be asking yourself ‘why should I buy a dual fuel generator?’ and we’re going to tell you why.
It might seem easier to just buy a generator that is powered by either gas or propane, but it is a much better choice to buy a dual fuel generator.
They give you so much more flexibility and are much more reliable as you can switch the fuel type depending on what you have available. This is particularly important in times of emergency.
Gasoline can, on occasion, become difficult to source, whereas propane is readily available. So by buying a dual fuel generator it allows you to switch to whichever you can get and reduces the risk of you ever being unable to power your generator.
It offers peace of mind, that in the event of an earthquake or a hurricane, which does happen fairly often in the USA, you will be able to use propane to power your generator even if there is a disruption to the gasoline supply.
You should also consider how important portability is to you. This will heavily depend on how you plan on using the device and will also probably be impacted by how powerful a generator you buy.
The majority of portable generators are smaller in size and in turn produce less power. However, the main reason you will want a portable generator is if you are using it to go camping or with an RV.
A smaller generator will be more than capable to provide power in both of these scenarios so there is no need to worry. Another reason you may want a portable generator is if you are doing work on a building site.
In this case, you will probably want a more powerful generator, which does make it more difficult to find one. However, some powerful generators do come with the ability to be made portable, but you should bear in mind that these will be more difficult to move about than smaller generators would be.
The importance of portability will depend on your situation, so you should consider all of your options before you make a purchase.
Finally, you should consider the power output of the generator. Even the smallest of generators usually have enough power to provide electricity to the majority of household appliances, however, they will be unable to power them all simultaneously.
The most popular Watts rating of the generator is probably the models that output approximately 4,000/5,000 as they offer the perfect balance between big and small.
If you only want to use the generator occasionally, for example on camping trips, a small generator will be able to do the job. However, if you want a device that will be able to supply electricity to your home in the case of a power outage, you will want a generator that exceeds 7,500 running Watts.
Similarly, if you are using a generator on a building site, a smaller generator will be able to supply energy to one power tool, but if you want to be able to operate multiple simultaneously, a more powerful generator would be more appropriate.
Frequently Asked Questions
What is a dual fuel generator?
Dual Fuel generators are the same as a normal generator, except they have the capability to be powered by either gasoline or propane. Some dual fuel generators can even be powered by diesel, however, gasoline and propane are the most common.
Dual Fuel generators are a popular choice because they give you a lot more freedom and can be more reliable.
If you are unable to source gasoline for your generator you can use propane, and vice versa. This is always good as generators are most commonly used in times of emergency, so if you are unable to get hold of the fuel that you normally use, you can easily switch to the other.
Are propane generators quieter than gas?
As dual fuel generators can be fueled by either propane or gas, it can be difficult to tell which performs quieter.
However, propane generators do tend to perform quieter than gasoline generators as they are clean burning.
So, if you want your dual fuel generator to perform quieter, it might be a better choice to use propane as the fuel rather than gasoline to fuel it.
Can a whole house generator be dual fuel?
Yes, dual fuel generators come in all different sizes, and there are many different types available that are large enough to power your whole home.
In order to power your whole home on the generator, in a power outage, you should buy a generator which exceeds 7,500W running power.
However, if you want to keep everything running in your home, bigger is better so you should buy as powerful a generator as possible for the best results.
