Buying Guide: How to Choose a Dual Fuel Generator for Home Backup
When I started looking for a home backup generator, I quickly realized the flexibility of a dual-fuel model was a game-changer. Being able to switch between gasoline and propane gives me options during an outage, which is exactly what I need for peace of mind. But not all dual fuel generators are created equal. Here’s what I learned you should focus on when picking one out.
First, you need to figure out your power requirements. This is the most important step. I made a list of the essential appliances and devices I’d need to run during a power outage—things like the refrigerator, a few lights, the furnace fan, and maybe a sump pump. Add up their starting (surge) watts and running watts. This total will tell you the minimum generator size you should be looking at. It’s always better to have a little extra capacity than to come up short when you need it most.
Next, consider the runtime and fuel efficiency. A key advantage of dual fuel is that propane burns cleaner and stores for much longer than gasoline. I pay close attention to the runtime figures provided by the manufacturer, usually at a 50% load. A generator that can run for 10-12 hours on a single tank of propane or gas means less frequent refueling and more uninterrupted sleep during a long night.
Portability and outlets are also huge factors. Even for home backup, you might need to move the generator. Look at the weight and whether it has wheel kits and folding handles. Then, check the outlet panel. Make sure it has the right types and number of outlets for your needs, including heavy-duty 120/240V outlets for larger appliances. For me, a model with a Transfer Switch Ready outlet is a major plus for safer connection to my home’s electrical panel.
Finally, don’t overlook features that improve the user experience. An electric start is a fantastic convenience, especially in bad weather. A CO Detect technology that automatically shuts the unit down if carbon monoxide builds up in an enclosed space is a critical safety feature for any home. When I was comparing models, I found that paying a bit more for these quality-of-life and safety features was absolutely worth it for my family’s 10 best dual fuel generators for home backup needs.
FAQ
What are the main advantages of a dual fuel generator?
The biggest advantage is fuel flexibility. If gasoline is in short supply after a storm, I can switch to propane, which also has a much longer shelf life. Propane burns cleaner, which means less carbon buildup in the engine and potentially longer maintenance intervals. It’s also often quieter and produces fewer emissions than running on gasoline alone.
Can I connect a dual fuel generator directly to my house?
You should never plug a generator directly into a wall outlet. This is called “backfeeding” and is extremely dangerous for utility workers and can damage your home’s wiring. The only safe way to connect it to your house is through a professionally installed transfer switch. This device isolates your home from the grid and allows you to power specific circuits safely.
How often should I perform maintenance on my generator?
Regular maintenance is crucial for reliability. I check the oil before every use and follow the manufacturer’s schedule for oil changes, which is typically after every 50-100 hours of operation. I also run the generator for about 30 minutes every month with a load to keep the engine parts lubricated and the battery charged. Always consult your owner’s manual for specific intervals.
Is it safe to run a dual fuel generator in my garage?
No, it is never safe to run a generator indoors, including in a garage, even with the door open. Generators produce deadly carbon monoxide gas that can quickly build up in enclosed or partially enclosed spaces. Always place the generator outside, far away from windows, doors, and vents to ensure exhaust fumes are directed away from your home.
What size dual fuel generator do I need to power my entire house?
Powering an entire house with all its appliances requires a very large, and expensive, standby generator. For most of us, a portable dual fuel generator is for backing up essential items. To determine the size, you’ll need to calculate the total wattage of the essentials you want to run simultaneously. A unit in the 7,500 to 12,000-watt range can typically handle a well pump, refrigerator, lights, and a heating system, covering the critical needs for a 10 best dual fuel generators for home backup scenario.
How loud are these generators?
Generator noise is measured in decibels (dBA). Most modern portable dual fuel generators for home use operate between 60 and 75 dBA, which is roughly comparable to the sound of a normal conversation or a vacuum cleaner. Inverter generators are generally much quieter than conventional open-frame models. If noise is a concern, look for a model specifically marketed as “quiet” or with a low dBA rating.
