The Ultimate Guide To Gas Vs Propane Generator

Generators are gold during times of emergency. Gas vs propane generator is the most sought after. Selecting either a gas or a propane generator depends on what is your purpose for using it. Most of us depend on electric companies to supply us with electricity. But sometimes the electricity system fails.

This means no lights, no heat, no TV, no refrigeration, among other things. We can go without watching TV, but some other things are critical. That is why it is so important to have these power generators on standby. Even those people that live off the grid need a standby generator. The big question now is whether to go for the gas Vs propane generator. Below we look at the pros and cons of the two options.

Propane Generators

Propane generators work by transforming propane energy into electricity through combustion. Propane is a consequence of refining petroleum and processing natural gas. Propane generators are available in both portable and standby options and can be used to power machines and run appliances at home.


Using propane for energy has several advantages that are not found in other types of dual fuel generators. Propane gas burns immaculately and has a long shelf life. A 100-pound propane gas tank has a typical expiration duration of 12 years from its manufacturing date.

Once it has reached its date of expiration, it will require a replacement or an inspection to ascertain if rehabilitation is viable to give it five additional years of service.

Another advantage of buying a propane-powered generator is that in case a natural disaster strikes or of a similar occurrence, there will be no disruption in the supply. If you were using a gas generator, you would anticipate that the gas supply will be disrupted after a short time, but for propane, the supply will continue for much longer.

Moreover, propane is also stored in cylinders, which are not only easily accessible but also easily stored for a long time.

When planning for your future energy needs, it is impossible to know how long or how often you will need to utilize your generator. Your fuel might have to sit idle for many months and sometimes even years before you need it.

In case you find yourself in such a predicament, propane will prove to be more desirable compared to gasoline or diesel fuel because propane does not degenerate. It will stay safe and uncontaminated if it is stored in the original container.

It is, therefore, easy to store substantial amounts of the fuel without fearing that it is going to become contaminated, or it will deteriorate with time.

Propane is a green fuel in that it is friendly to the environment and burns quietly. Moreover, it burns cleanly, producing very low amounts of carbon monoxide. Large amounts of carbon monoxide cause death by suffocation. Large amounts of carbon monoxide are also hazardous to plants and other living things. The low amount of carbon monoxide produced by propane means less harm to the environment.

Propane storage is done in enormous containers and safe tanks that obliterate the risk of wastage or spillage when filling the tanks up or during storage. It is safer to store propane near your home compared to gasoline, which is highly flammable. Naturally, propane should be stored outside on a non-flammable and flat surface like concrete away from any source of the fire.


Propane is environmentally friendly, safe, and durable, but they also have their limitations. Propane generators are more costly than their gasoline counterparts. Propane also gives out less heat energy compared to gasoline; they can give out up to 30% less heat and are, therefore, less effective as a source of heat energy. Propane generators are usually bulky and, therefore, difficult to move compared to gasoline generators.

It is hard to detect propane in case of leakage. This is because propane is heavier than air and will sink to the lower parts. This means that you will smell leaked propane a little too late, this makes them very dangerous. If you are using the propane generator, you will need to constantly inspect the clamps, pipes, and fittings to ensure that there is no leakage.

Gas Generators

Gasoline generators are the most sought after generators because they are affordable and very effective. The internal combustion engine of the gas generator rotates an electric motor; this generates an electromagnetic induction that makes the generator to work.


The gas generator has a few advantages over its propane counterpart. The number one reason why most people prefer gasoline generators to propane generators is their affordability. It is relatively cheap to buy and install a gas generator. A basic generator that can be used at home or for camping goes for between $500 and $4000 depending on the model. You must select a model that will meet all your power needs in case of an emergency.

Gasoline generators are more effective than propane generators in putting out heat; they put out up to 30% more heat using the same amount of fuel. Except if you are in a place where propane is considerably cheaper than gas, it is more prudent to buy the gasoline generator.

Gasoline generators are also smaller in size compared to propane generators; this makes them easily portable. Gasoline generators have an in-built tank, unlike their counterpart, which has an exterior tank, thus maneuvering them is more manageable.


Without a doubt, propane-powered generators have their limitations. When left in the generator tank for a while, gasoline usually degenerates. You will be required to replace the gas to maintain good quality consistently. The fuel should be replaced every six months to ensure that it stays fresh.

Gasoline is also not as friendly to the environment as propane. When gasoline burns, it emits a lot of carbon monoxide and carbon dioxide that is toxic to the environment. This is something you should put into consideration before selecting the type of generator you want to buy.

Moreover, gas generators are not as practical as propane generators. Propane generators can be connected to a tank and be available for use at any moment. Gasoline generators, however, will require that you go to the gas station whenever a need for its use arises. In the case of an emergency, for instance, in a gas station, it will lead to disruption of services indefinitely.

Selecting a Generator    

It is wise to take into consideration the characteristic of the fuel that is important to you when you’re choosing a generator. If your budget is tight and you have no problem with having to replace your gasoline regularly, then you should go for the affordable gasoline generator.

If, on the other hand, you are looking for a generator whose fuel will not degenerate over time, and if you don’t mind paying more for a generator, then the propane generator is the best choice for you.

Other essential features that you might also need to take into consideration about gas Vs propane Generator when choosing a generator are:

  1. Automatic start: this feature will make your generator to start itself in case of a power outage automatically. This is especially important if you depend on a consistent supply of electricity to operate important machinery.
  2. Electric start: in the case that an automatic start is not available or is not that important, you can go for the electric start alternative. This will allow you to make your generator to start operating with the simple push of a button.
  3. Fuel gauge: a fuel gauge is used to show how much fuel you have in your generator at a given time. This can be handy when the blackout lasts for a long time. It will enable you to prepare in advance so that there will be no disruptions until the main electricity comes back.
  4. Having several outlets: the generator you select must have multiple outlets just in case you will need it. You may need to use it, so it is best to choose one that offers you several outlets.
  5. A console that can be removed: a removable console can be a useful safety feature. It eliminates the need for outdoor extension cables, allowing you to plug in your appliances directly.

A generator is critical, and having it ready in your home allows essential appliances to continue operating, ensures that you can cook, keeps your house warm or cool, and also keeps the lights on.

However, not all generators are the same. It is advisable to think about the features to determine the best generator for you. Propane and gasoline generators are the most common and the most sought after generators.

It is essential to consider all angles before going for either a gasoline or a propane generator. In times of disaster, gasoline may be in short supply, and it is also not practical to store gas, especially in the long term. Propane is more practical, especially in the case of an extended blackout, but it is also more expensive compared to gasoline.
