Westinghouse 13500 Peak Watt Tri-Fuel
This Tri-Fuel model supports gasoline, propane, and natural gas, delivering 13,500 peak watts on propane and 10,000 peak watts on natural gas. It includes remote start and transfer switch readiness, with a 9.5-gallon tank for long runtimes and a digital hour meter. Best for homeowners who want flexible fuel access and a remote start feature for quick power restoration after outages. A potential limitation is the heavier weight and larger footprint typical of tri-fuel units.
DuroStar DS13000MXT 13,000-Watt Tri Fuel
With 13,000 watts of power and Tri Fuel versatility, this generator can run on gasoline, propane, or natural gas. It features a push-button start and a transfer switch-ready panel that supports a 50-amp outlet. It’s a solid choice for those who want strong whole-home backup with simple operation. The main caveat is that tri-fuel systems can require more maintenance and monitoring of multiple fuel lines and regulators.
Westinghouse 14500 Peak Watt Tri-Fuel
This model provides a higher peak output—up to 14,500 watts—with a 11,500 running watts on gasoline, and robust runs on propane or natural gas. It uses a heavy-duty 550cc Westinghouse engine with a long-life cast iron sleeve and offers a fuel gauge for planning. Best for larger homes or frequent power users. A limitation to watch is the size and weight, which impacts mobility and storage.
Generac 12,500 Starting Watt Tri-Fuel
Generac’s Tri-Fuel unit delivers 9,500 running watts and 12,500 starting watts with three fuel options. It includes COsense CO detection and automatic voltage regulation (AVR) for steady power to protect appliances. It’s well-suited for homes seeking dependable starting power plus safety features. A potential limitation is that high surge loads require careful management to prevent tripping in older electrical systems.
Westinghouse 14500 Peak Watt Dual Fuel
This dual-fuel model provides 14,500 peak watts and up to 11,500 running watts on gasoline, with strong performance on propane. It shares the transfer switch readiness and remote start features common to the line, making it a robust choice for larger homes. A limitation is similar to other large units: storage and transport can be challenging for single-average garages or sheds.
Buying Guide
- Fuel flexibility: If you want the option to switch fuels quickly during supply disruptions, prioritize Tri-Fuel or Dual/Triple Fuel designs.
- Power needs: Calculate your essential loads (refrigeration, HVAC, sump pump, lights) to choose a unit with adequate peak and running watts. Look for models offering above your critical load to handle startup surges.
- Start method: Remote electric start is convenient for frequent outages. Consider recoil or manual start only if you prefer lighter weight or lower maintenance.
- Transfer switch readiness: For automatic home backup, select models with a transfer switch-ready output and a compatible transfer switch installation.
- Runtime and tank size: Longer runtime reduces refueling interruptions. Note tank capacity and fuel gauge to estimate daily usage.
- Safety features: CO detection, automatic shutdown for low oil, and proper ventilation are important for safe operation in residential areas.
- Weight and mobility: Tri-fuel and high-watt models are heavier. Plan for storage space and the method you’ll use to move or secure the generator.
- Maintenance: Regular oil changes, air filter checks, and spark plug maintenance extend life and reliability. Consider models with easy access panels.
FAQ
- What does tri-fuel mean?
Tri-fuel generators run on gasoline, propane, or natural gas, offering fuel flexibility during outages. - Why choose a natural gas powered generator for home use?
Natural gas is often readily available through existing lines, which can simplify refueling during extended outages. - What is “transfer switch ready”?
It means the generator can connect to a home’s electrical system via a transfer switch for automatic power transfer. - What should I consider for safe operation?
Place units outside, away from doors and windows, with proper ventilation and CO safety features in mind. - How many watts do I need for essential loads?
Identify critical devices (furnace, fridge, sump pump) and sum their wattage; aim for a unit with higher running watts than your total continuous load plus startup surges. - Is remote start worth it for home backup?
Yes, it enhances convenience during cold mornings or in adverse weather when reaching the generator is difficult.
