Technological advancements have made power generation easy for the average person. With so many types of generators on the market, you have the luxury of choosing from an extensive list. The generator menu includes small portable power stations, mid-size generators, inverters, heavy-duty worksite generators, and whole-house standby units.
Every generator has its advantages and limitations. For example, a power bank is suitable for running small sensitive appliances but cannot power large machines. Mid-size portable generators can run small to medium appliances but cannot support big machines or tackle heavy power loads. In contrast, inverters deliver enough power to run small appliances and have a low-level THD (below 5%) ideal for sensitive machines like laptops, phone chargers, and sound systems. They are also fuel-efficient and silent compared to conventional generators.
Big portable generators can manage large power loads and are recommended for worksites and large households, but they are difficult to move around and are costly. Standby units are safe for all appliances and can power almost everything in your home; however, they need a lot of space for installation and are also expensive.
Apart from portable power stations, all other types of generators come in dual-fuel options. A dual fuel generator can run on two fuels. For portable generators, the fuels are mostly propane and gasoline. For standby units, the fuels are natural gas, propane, diesel, and gasoline. One machine supports only two fuel types.
Let’s delve into dual-fuel, portable generators in more detail!
Dual-Fuel Generators – A Synopsis
Disaster-based power outages have increased by as much as 70%; as a result, homeowners have started to buy dual-fuel generators. These generators come in handy when one type of fuel is depleted, as you can switch the generator to run on the other fuel and keep your essential appliances or machinery powered.
What is a Dual Fuel Generator, and How Does It Work?
A dual fuel generator uses gasoline and propane to supply alternate electric power to run your home, worksite, or outdoor appliances. There is no difference in the working of a dual-fuel generator compared to a single fuel generator. However, you do get a fuel selector switch/dial when selecting the fuel type. A dual fuel generator starts the same way, has equal maintenance needs, and is versatile. But in contrast, it is slightly more costly than gasoline generators with the same features and power output.
There are, however, some differences based on the efficiency and output of both fuels. Review the section below to understand these differences.
Propane vs. Gasoline
- Power Output. Gasoline burns better compared to propane; therefore, it can deliver more power output. The difference in output is around 200-1500 watts depending on the size of the generator.
- Runtime. The runtime for small generators is the same or higher when running the machine on propane. However, for larger models, propane offers less runtime as compared to gasoline.
- Exhausts. Propane is more eco-friendly compared to gasoline. Gasoline has more CO2 content than propane. In addition, it also contains other harmful toxins such as benzene, formaldehyde, ethylbenzene, and butadiene.
- Safety. Propane is safer than gasoline as there is no spillage risk involved while connecting the propane cylinder to your generator. However, it is flammable, but this risk is not as high as gasoline.
- Availability and Shelf Life. Both fuels are available throughout the year. However, gasoline becomes challenging to find during natural disasters such as floods and hurricanes when travel is difficult, and the supply of fuel is interrupted. Stored propane can come to your rescue in these scenarios because it has an unlimited shelf life, while gasoline has a limited shelf life of 3 months.
Why is It a Good Investment?
- A dual fuel generator is a good investment because it offers you peace of mind knowing that you have access to power in any situation.
- It is a reliable machine. You can use gasoline in normal weather conditions, such as dealing with short-term outages, or camping purposes. For disaster-based emergencies, you can use stored propane.
- Dual fuel generators allow you to choose the fuel according to the weather. Propane becomes dense in winter, and gasoline can catch fire in extreme summers. You can use propane in summers and gasoline in winters.
- Propane is cheaper than gasoline. Therefore, it gives lower running costs than gasoline in the long run.
- You don’t have to rush to restock your fuel as you can run your generator on either fuel.
Limitations:
- The upfront costs are higher than single-fuel generators.
- It is challenging to transport two types of fuel.
- Output on propane is low; it won’t run some of your heavy appliances.
Dual Fuel Generator Buying Guide
A portable generator lasts for 8-10 years. However, this is only possible if you buy the right machine. We know that the build quality and durability play an essential part in enhancing the life of your machine, but if it lacks the relevant features, you won’t be able to use it in the long run. Therefore, we have listed all the features you need to consider before buying a Westinghouse dual fuel generator.
Features You Need to Consider Before Buying a Generator
Power Needs
Calculate your power requirements by making a list of all the appliances you plan on running using your generator. Make sure you take into account starting and running wattages. Once you have the final figure, add a 300 watts cushion in starting and running watts. This will be your ideal power consumption during an outage. Compare it with the shortlisted generator’s output on gasoline and propane and decide for yourself.
Tank Capacity and Runtime
Don’t forget to look at the tank capacity and runtime. Make sure you estimate the runtime according to your calculated wattage to know how frequently you will need to refuel gas or how big a propane cylinder you would need. Just a safety tip: never run a portable generator for more than 8 hours in one go.
Portability
What’s the point of having a portable generator when you can’t move it easily? All Westinghouse generators on our list have heavy-duty wheels and ergonomic handles to make portability hassle-free.
Noise Level and Safety Features
The bigger the generator, the noisier it is. If you can’t tolerate high running sounds, then go for an inverter. Big machines can be noisy, so you may have your neighbors complaining. However, installing mufflers or building a sound reduction box to hush up your machine should reduce the noise level sufficiently. Lastly, look at the safety features like overload protection, low oil shutdown, and surge arrest.
Safety Tips and Usage Guide
- EPA recommends placing your generator at least 15 feet away from any buildings, windows, doors, RVs, or campsites.
- Never run your machine without a canopy if it is raining or snowing.
- Always operate the machine with dry hands and dry clothes.
- Never refuel or repair/change the oil on a host machine.
- Never overload your machine.
- Always use a transfer switch for connecting your machine to your home, and never connect your generator to a wall outlet.
- Inspect and maintain your generator regularly.
- Always follow the manufacturer’s directions at all times.
