Getting electrical power for your home isn’t much of a challenging today, since there are a range of portable generators that you could use for your home and/or business. With today’s more advanced technology, there are versatile and portable generators that prove to be more efficient for your home, especially for homes located in remote areas that might not have electric connectivity.

These generators perform excellently and efficiently, making them very reliable for lighting, as well as heating homes. This means that you could light up and heat up your home using these generators that produce enough watt for all your home’s electrical needs. Basically, there are three types of portable electric generators: the single fuel generators; dual fuel or bi-fuel generators; and the tri-fuel generators.

When buying whole house generator, you need a buying guide that will help you buy the right generator that will power all your electrical appliances and home systems such as lighting and HVAC system. But first, there is the need to know all the three different types of portable generators.

What’s the Difference Between Single Fuel and Dual Fuel Generators?

First, there are four main fuels used to operate or run portable electric generators. These fuels include: gasoline; diesel; liquid propane (LP); and natural gas (NG). Now, a single fuel generator use only one of the fuels mentioned above. Most single fuel generators run on either gasoline or diesel. For example, single fuel generator that use diesel will use only that fuel type, and not any other type. The same way, a gasoline single fuel generator will only use gasoline, and not any other fuel type. In other words, you only have one choice of fuel when you buy a single fuel generator.

On the other hand, a dual fuel generator runs on two fuels types. With dual fuel generators, you can use an alternative fuel when the one that you normally use becomes scarce. For example, a dual fuel generator that runs on liquid propane gives you the chance to choose gasoline when liquid propane becomes scarce or more expensive. A tri-fuel generators use any one of three fuel types. For example, you could run them on liquid propane, gasoline or natural gas. Portable generators have indications of the fuel type(s) that you could use. This is a very vital and critical information that you will know.

Why is a Dual Fuel Portable Generator Better?

Multi fueled electric generators such as dual fuel generators have advantages over their single fuel counterparts. So, what are some of the benefits of using these types of electric generators?

First, dual fuel generators are versatile and efficient. Since they use two fuels to generate electricity, you have the chance to use a cheap alternative fuel source in case the fuel type that you normally use either becomes more expensive or scarce for any reason. Also, dual fuel generators are efficient at providing stable electric power that can power all your home’s electrical appliances and home systems for longer time. Most dual fuel generators operate on either liquid propane or natural gas. In case the propane or the gas is unavailable for some reason, you will still use the other fuel type, as an alternative fuel source.

Secondly, dual fuel generators offers you longevity in terms of electric power supply. Since dual fuel generators have two fuel storage units or tanks, you could operate your generator on one fuel, and automatically switch to the other type of fuel when the first fuel runs out. Your generator will switch to the other available fuel, thus serving you longer than a single fuel generator would.

Dual fuel generators also lets you switch between fuels during operations, thus providing you with convenience. For example, you could start your dual fuel generators on gasoline, and then switch to liquid propane later. This is an advantage that will help you utilize a fuel type that operates best under some weather conditions but don’t in others.

The versatility of these kinds of generators will set you ahead of your business competitors who might have single fuel electric generators. When one fuel type becomes scarce because of some adverse weather conditions, you still have an alternative solution to your homes or even business’ electrical power needs. Therefore, if you want reliability, versatility and efficiency as far as fuel generated electricity is concerned, then dual fuel generators are one of your best electrical power solutions.

What are some of the disadvantages of these types of electric generators?

Even though dual fuel electric generators have profound benefits as far as electrical power supply in areas cut off from the national grid are concerned, they have a few drawbacks. First, these types of generators are more expensive than their single fuel generators counterparts. And for this, reason you will have to plan and budget for you to buy the best dual fuel generator. For example, a dual fuel generator of the same size as the single fuel generator will cost more.

Also, finding the best dual fuel generator could prove to be a nerve-wrecking search since there are so many types of dual fuel electric generators that are specialized and designed differently depending on various needs. And for this reason, you will need a very detailed buying guide to help you in your search for the best and most efficient dual fuel electric generator.

Therefore, for you to buy one of these efficient and excellent portable generators, you will need to plan well and budget so that you a reliable and efficient alternative electrical power source.

Which type of fuel is more efficient?

There are four main fuel types that could be used to power electric generators. These fuel types include: gasoline; liquid propane; diesel; and natural gas. These fuels have their pros and cons.

Gasoline

Gasoline is the number one choice of most generator users. It’s readily available and also very affordable. However, this fuel has some drawbacks that make it unsuitable for use under certain weather conditions and/or beyond specific times. For example, gasoline is highly inflammable and isn’t ideal for use under very low temperatures. Also, it has a short shelf lie. This means that you can’t store it beyond a period of, say, 1 year for later use. If you don’t use fresh gasoline, the carburetor of your dual fuel generator might clog and emit very hazardous effluents. You should, therefore, keep the gasoline fresh and keep your carburetor under checks and maintenance.

Diesel

When you want higher watts of electrical power, then dual fuel generators that use diesel as one of their fuels is your solution. Diesel is a fuel that has high fuel efficiency. If your business needs 150kW of electricity or more, then you will buy a generator that operates on diesel as its fuel source. Also, diesel are less inflammable as compared to gasoline fuels. And for this reason, you could use them in areas with cold temperatures. Diesels have shelf life of 1-2 years. Also, you could use them together with fuel additives, under frigid temperatures.

Liquid propane

Liquid propane has indefinite shelf life. This means that you could leave the propane fuel inside your dual fuel generator for years and use it without any problem. Your generator will start without problems. Also, propane doesn’t clog the carburetor of your dual fuel generator. Generators which use propane are also ecofriendly since they are silent.

Enough with the praises. Propane fuels are more expensive than gasoline. Also, the installation and maintenance of generators that use propane is very complex and expensive. Also, these generators have shorter lifespan, and higher fuel consumption as compared to both gasoline and diesel dual fuel generators.

Natural gas

You probably are already using natural gas for cooking and heating your home. This gas could also be used to power up generators. This fuel type is beneficial since it’s easily obtainable and could operate even under frigid temperatures without any problems. Generators that use natural gas have higher engine life. This means that these kinds of generators will serve you for a long time.

However, natural gas-powered dual generators have higher fuel consumption. Also, the supply of natural gas might be limited during adverse weather conditions or disasters such as earthquakes due to wreckage of gas pipes. Depending on where you come from, you could choose the ideal fuel for your electric generator.

Locations limitations

Before buying a dual fuel generator, consider how far or near is your generator’s fuel source? If your areas has affordable and readily available gasoline, you could proceed to buy a generator that use gasoline as one of its fuels. But when gasoline is not readily available because of natural disasters that causes breakage of transportation pipelines, you could switch to another dual fuel generator.

Also to take into consideration is your area’s local weather conditions. Different fuels are affected by weather differently. For example, gasoline don’t power generators well under very cold weather conditions. For this reason, you will require a different type of dual fuel generator that uses another fuel, say diesel, which could run in frigid weather conditions. Different dual fuel generators operate under different temperatures. Some can handle the cold outdoor weather, while some can’t. For all these reasons, take into consideration that weather under which you will want to operate your dual fuel generator.

Also, the control panel should have indicator lights on it; oil and fuel gauge to help you monitor their levels; and fuel meter.

Also, look for a portable generator with a 120 volts receptacle if you intend to use it to power your home’s electrical appliances. But if you are buying your generator for business use, you could go for a dual fuel generator with a 240 volts receptacle or power outlet. And for recreational use, you could need a 12 volts DC power outlet, for your vehicle’s battery.
