Westinghouse 12500 Watt Dual Fuel — Best for Moderate Homes
The 12500 Watt Dual Fuel generator delivers up to 12500 peak watts on gasoline and 11200 peak watts on propane. It features a remote start with a key fob, electric and recoil start, and a 6.6 gallon tank with a fuel gauge for up to 12 hours of run time. It includes a transfer switch ready 120V outlet and an RV/30A/50A configuration, plus GFCI outlets for safety. Best for: homes needing reliable backup power with moderate appliance loads and a switch-ready setup. Limitation: propane performance is lower than gasoline, so plan fuel strategy accordingly.
Westinghouse 14500 Peak Watt Tri-Fuel — Best for Large Homes
This model provides 14,500 peak watts and 11,500 running watts on gasoline, with 13,500 peak and 10,500 running watts on propane, and 12,000 peak/9,500 running watts on natural gas. Equipped with a heavy-duty engine and a long runtime on a 9.5-gallon tank, it supports substantial loads for extended outages. Best for: households with high power needs and access to multiple fuel sources. Caution: natural gas operation may require proper gas supply and connection arrangements.
Westinghouse Outdoor 14500 Dual Fuel — Best for Mobility
Similar in power to the Tri-Fuel version, this model focuses on portability with dual-fuel capability. It provides the same 11,500 watts gasoline and 10,500 watts propane, plus a 9.5-gallon fuel tank for lengthy run times. Best for: homeowners who may need to relocate the unit or require a portable backup for larger homes. Limitation: propane performance may be lower than gasoline, affecting peak power available.
DuroMax XP13000EH — Best for Whole-Home Backup
The XP13000EH delivers 13,000 watts of continuous output on either gasoline or propane. It is designed for whole-home backup and is transfer-switch ready, making it a strong candidate for larger loads. Best for: households seeking a robust, dual-fuel option with broad compatibility. Caution: data notes emphasize “whole home backup” but exact outlet mix varies; verify before purchase for your panel configuration.
Westinghouse 13500 Peak Watt Tri-Fuel — Top Power Trio
This unit offers 13,500 peak watts with 10,500 running watts on gasoline, plus strong propane and natural gas support. It includes a 9.5-gallon tank and a full transfer-switch-ready setup, with multiple 120V and 240V outlets. Best for: households requiring maximum flexibility and high power with fuel variety. Limitation: higher power often means larger footprint and heavier unit; ensure location and ventilation are adequate.
Buying Guide
What power level do you need? For smaller homes with essential circuits, a generator in the 6,500–10,000-watt range may suffice. For whole-house backup, consider 11,500–13,000+ watts and a transfer switch. How many fuel options do you want? Dual- or tri-fuel units offer flexibility during fuel shortages, but may come at higher upfront cost. Do you need portability? Portable models let you move the unit, but retrofit into a fixed system requires planning for exhaust, noise, and placement. Is natural gas available? If yes, natural gas or propane can provide a steady supply; keep in mind running watts vary by fuel. Check run time vs. tank size to estimate outage duration. Always confirm transfer-switch compatibility with your electrical panel and local codes.
Frequently Asked Questions
- What is peak wattage and running wattage, and why do I care?
– Peak watts indicate maximum surge power; running watts show sustained output. Choose based on the continuous load you expect during an outage. - Is dual fuel better than single fuel?
– Dual fuel offers flexibility if one fuel runs low, but may come with more maintenance and initial cost. - Do I need a transfer switch?
– A transfer switch simplifies safe connection to your home circuits and is commonly recommended for whole-house setups. - How long can a generator run on a tank?
– Run time depends on engine size and load; higher loads reduce runtime. Always check the manufacturer’s fuel capacity and efficiency data. - Can I run a generator indoors?
– No. Generators must be used outdoors in a well-ventilated area to prevent carbon monoxide buildup. - What maintenance is required for standby power?
– Regular oil changes, air filter checks, and battery maintenance are typical; follow the manufacturer’s schedule.
