Buying Guide: How to Pick the Right Dual Fuel Generator for Emergencies
When the power goes out, having a reliable generator is a game-changer. I think a dual fuel model is the smartest choice because it gives you options. You can run it on gasoline or propane, which is fantastic when fuel supplies get tight. But with so many models out there, how do you pick the right one for your home? I focus on a few key things to make sure I get a unit that will actually work when I need it most.
First, you need to figure out how much power you really need. This is the most important step. I make a list of the essential appliances I want to run during an outage—things like the refrigerator, a few lights, my phone charger, and maybe a well pump or furnace fan. Add up the starting watts (the surge power they need to turn on) and the running watts (the power they need to operate). Your generator’s output needs to handle that total. For most homes, a unit between 4,000 and 8,500 watts will cover the basics, but if you want to power central air conditioning, you’ll need to look at the higher end of that range or beyond.
Next, consider the runtime. How long can the generator run on a single tank of gas or a standard 20-pound propane tank? I look for models that offer a long runtime at 50% load. This is crucial because you don’t want to be refueling every few hours, especially in the middle of the night or during bad weather. Propane often provides a longer, more stable runtime and it doesn’t degrade over time like gasoline, making it a great fuel for long-term storage.
Portability and outlets matter more than you might think. Even if you don’t plan on moving it often, wheels and a folding handle are a must for getting it out of the garage and into position. Check the outlet panel to ensure it has the right types and number of outlets for your needs, including a heavy-duty 240-volt outlet for large appliances like a well pump or electric range. Finally, I always look for modern features like an electric start for easy operation and a carbon monoxide shutoff sensor for safety, especially if the generator will be used anywhere near the house. Taking the time to think through these points will help you find one of the best dual fuel generators for emergencies that fits your specific situation.
Frequently Asked Questions
What are the main benefits of a dual fuel generator for emergency use?
The biggest benefit is fuel flexibility. During a prolonged power outage, gasoline can become scarce or even go bad if it’s been sitting in your can for too long. With a dual fuel generator, you can switch to propane, which has a virtually infinite shelf life and is often cleaner burning, which means less maintenance on the engine. This flexibility gives you peace of mind, knowing you have a backup plan for your backup power.
How do I calculate the right size generator for my home?
I start by making a list of the absolute essentials I need to power. For each item, find its starting watts (or surge watts) and running watts. You can usually find these numbers on a label on the appliance itself or in the user manual. Add up all the running watts for the items you plan to use simultaneously, and make sure the largest starting watt value on your list is within the generator’s surge capacity. It’s always better to have a little more power than you think you’ll need.
Is it safe to run a dual fuel generator indoors or in my garage?
No, it is never safe to run a generator indoors. This includes garages, basements, or even sheds with the door closed. Generators produce deadly carbon monoxide gas that can quickly fill an enclosed space. You should always place the generator outside, far away from windows, doors, and vents to ensure the exhaust fumes are carried safely away from your living areas.
Can I connect a dual fuel generator directly to my home’s electrical panel?
You should only do this with a professionally installed transfer switch. Plugging a generator directly into a wall outlet, known as “backfeeding,” is extremely dangerous and is a fire hazard. It can also electrocute utility workers who are trying to restore power. A transfer switch is the only safe and legal way to connect a generator to your home’s wiring system.
How often should I perform maintenance on my emergency generator?
Even if you don’t use it, you should perform basic maintenance regularly. I check the oil level before every use. I also start and run the generator for about 20-30 minutes every month or two with a light load to keep the engine parts lubricated and the battery charged (if it has an electric start). Always follow the specific maintenance schedule in your owner’s manual, which will include tasks like changing the oil and spark plug at recommended intervals. This ensures your unit is ready to go when you need it. When you are looking for the best dual fuel generators for emergencies, considering the maintenance requirements is a key part of the decision.
