Buying Guide For Dual Fuel Whole House Generators
When selecting a dual fuel whole house generator, there are several important factors to consider to ensure you get the right fit for your home and emergency needs.
1. Power Output and Compatibility
Assess your home’s electrical load to estimate the wattage needed. Consider both running watts (continuous) and surge watts (starting power for appliances like refrigerators). Generators ranging from 9,500 to over 14,000 watts typically support whole house backup applications, but prioritize models with transfer switch readiness for easy integration.
2. Fuel Type Flexibility
Dual fuel generators operate on gasoline and propane, while tri-fuel models add natural gas compatibility. Propane offers cleaner burning and longer shelf life compared to gasoline. Having multiple fuel options ensures adaptability during fuel shortages or emergencies and helps optimize runtime.
3. Engine Durability and Features
Look for generators with heavy-duty engines featuring cast iron sleeves or copper windings, which enhance durability and heat dissipation. Additional features like automatic low oil shutdown and carbon monoxide detection increase safety and protect your investment.
4. Start Mechanism
Electric or remote electric start systems improve user convenience compared to recoil start methods. They allow quick and effortless generator activation, especially in adverse weather or emergency scenarios.
5. Runtime and Fuel Tank Capacity
Longer runtime on a single tank reduces the need for frequent refueling during outages. Generators with larger fuel tanks and fuel gauges can run for 12 hours or more, providing uninterrupted power through extended outages.
6. Outlet Types and Safety
Ensure the generator provides standard household outlets as well as dedicated transfer switch and RV power receptacles. Rubber covers over outlets add protection against debris and moisture. Ground fault circuit interrupter (GFCI) outlets improve shock protection.
7. Noise Level
Consider models that operate at lower decibel levels to reduce noise pollution around your home or job site, making them preferable for residential neighborhoods.
Carefully comparing these factors with your home’s power profile and emergency plans will help you select a dual fuel whole house generator that reliably maintains your household power needs regardless of the outage scenario.
