Buying Guide: What to Look for in a Tri Fuel Generator
Power Output: Running Watts vs. Peak Watts
Your generator’s power output determines what appliances it can run. Running watts indicate continuous capacity, while peak watts cover startup surges. For whole-home backup, look for models like the Westinghouse 14500 Peak Watt Tri Fuel Home Backup that offer substantial running wattage. A good rule of thumb is to calculate your essential loads and add 20 percent for margin. Just as you carefully compare mower engine brands, matching generator output to your needs prevents overloads.
Fuel Flexibility: Gas, Propane, and Natural Gas
The main advantage of a tri fuel generator is the ability to switch between fuels. Gasoline is widely available but has limited shelf life. Propane stores indefinitely and burns cleaner. Natural gas offers unlimited runtime if connected to a utility line. Models like the DuroMax XP13000HXT and the Generac 12,500 Starting Watt Tri Fuel Portable Generator let you choose the most convenient fuel source. Consider your local fuel availability and storage options. This decision is akin to selecting the right mower for your lawn; our guide on choosing a zero turn mower can help you think through similar trade-offs.
Features: Remote Start, CO Sensor, and Transfer Switch Readiness
Modern tri fuel generators come with features that enhance convenience and safety. Remote electric start lets you fire up the generator from inside your home. A CO sensor automatically shuts off the engine if carbon monoxide levels become dangerous. Transfer switch readiness simplifies connection to your home’s electrical panel. The Westinghouse 13500 Peak Watt Tri Fuel Home Backup and the DuroStar DS13000MXT both include these essential features. For more on property equipment, visit our property equipment page.
Final Thoughts
Choosing the best tri fuel generator comes down to your power needs and fuel preferences. For high-capacity whole-home backup, the Westinghouse 14500 Peak Watt Tri Fuel Home Backup delivers exceptional reliability and remote start convenience. If you are looking for a more budget-friendly option without sacrificing versatility, the DuroStar DS13000MXT 13,000-Watt 500cc Tri Fuel offers solid performance with gas, propane, and natural gas support. Both models are transfer switch ready and include CO detection for peace of mind.
Frequently Asked Questions
What is a tri fuel generator? A tri fuel generator can run on three different fuel types: gasoline, propane, and natural gas. This flexibility allows you to choose the most available or cost-effective fuel during an outage. Most models require a simple adjustment to switch between fuels.
How do I choose the right size generator for my home? Calculate the total running wattage of essential appliances like refrigerators, lights, and HVAC systems. Add the highest starting wattage among them. For typical homes, a generator with 10,000 to 15,000 peak watts like the Westinghouse 12500 Peak Watt Tri Fuel Home Backup is often sufficient. Always consult a qualified electrician for transfer switch installation.
Can I run a tri fuel generator on natural gas permanently? Yes, many tri fuel generators can run continuously on natural gas as long as a municipal supply is available. This makes them ideal for whole-house backup without refueling. However, natural gas produces slightly less power than gasoline or propane, so check the derated wattage in the specifications.
Are tri fuel generators safe for electronics? Most modern tri fuel generators, especially inverter models like the Westinghouse 12000 Peak Watt Tri Fuel, produce clean power with low total harmonic distortion (THD). This makes them safe for sensitive electronics such as computers and smart appliances. For additional protection, use a surge protector.
