Buying Guide – How to Choose the Best Dual Fuel Generators
Selecting the right dual fuel generator requires evaluating several critical factors to ensure it meets your specific power needs and usage scenarios.
Power Output Requirements
Determine the total wattage needed for your essential appliances and tools. Peak watts handle startup surges while running watts support continuous operation.
Always choose a unit with at least 20% higher output than your calculated load to prevent overloading.
Fuel Type and Tank Capacity
Dual fuel generators run on gasoline and propane. Propane stores longer but gasoline has higher energy density.
Check fuel tank size to estimate runtime based on your expected outage duration.
Run Time Efficiency
Longer run times reduce the need for frequent refueling. Look for models offering 10 hours or more on gasoline.
Consider models with eco mode which adjust engine speed to save fuel when load is low.
Safety Systems
Carbon monoxide sensors are critical for safe operation near homes. Overload protection prevents damage to the generator and your devices.
Low oil shutdown features protect the engine from damage caused by lubrication issues.
Portability and Weight
Heavier generators offer stability but are harder to move. Ensure the unit has wheels and a telescoping handle if transport is required.
Consider the physical space you have for storage and operation.
Outlets and Compatibility
Check for outlets that match your equipment. RV ready outlets allow connection to recreational vehicles easily.
Transfer switch ready options enable safe integration with your home's main electrical panel.
Noise Level
Noise levels impact comfort for you and neighbors. Inverter models are quieter than standard open frame designs.
Look for decibel ratings under 70 dB for residential use.
Warranty and Support
A solid warranty protects your investment against defects. Manufacturers offering 2 to 3 year terms are preferable.
Check availability of local service centers for repairs.
How to Use and Care for Your Dual Fuel Generators
Always operate your generator in a well-ventilated outdoor area to prevent carbon monoxide buildup. Keep it at least 20 feet away from windows and doors.
Use clean fuel and check oil levels before every start. Drain gasoline from the tank if storing for long periods to avoid carburetor damage.
Run the generator under a light load periodically to keep internal components lubricated. Schedule annual maintenance checks for optimal performance.
Frequently Asked Questions
Can I run my entire house with a dual fuel generator?
It depends on the wattage of the generator. Larger models like 12000 watt units can power most essential circuits when paired with a transfer switch.
Is propane better than gasoline for generators?
Propane stores indefinitely without degrading while gasoline goes bad in months. However, propane produces slightly less power than gasoline for the same engine.
Do dual fuel generators require a special transfer switch?
You need a transfer switch that accepts 240V power. Most modern transfer switches support the 120/240V outlets standard on these generators.
How long should I wait to refuel the generator?
Wait until the engine cools completely before adding fuel. Hot engines can ignite fuel vapors causing serious safety hazards.
Are dual fuel generators safe for sensitive electronics?
Models with inverter technology and low THD are safe. Standard generators may have voltage fluctuations that can damage computers without a surge protector.
How often should I change the oil?
Change oil after the first 20 hours of use then every 50 to 100 hours. Refer to your user manual for specific maintenance intervals.
Can I start the generator automatically?
Some high end models support auto start via transfer switch integration. Basic models require manual electric start or pull cord ignition.
What is the difference between peak and running watts?
Peak watts cover short startup surges for motors while running watts support steady state operation. Always size for running watts plus startup surge.
Final Thoughts on Choosing the Best Dual Fuel Generators
We found the Westinghouse 12500 Watt model to be the best overall choice for home backup due to its balance of power and features.
Prioritize safety features like CO sensors and transfer switch readiness when selecting a unit. Consider your fuel storage capabilities when deciding on tank size.
Prices and stock fluctuate frequently so verify details on the product page before purchasing. Regular maintenance will ensure your generator is ready when needed.
