Buying Guide: Key Purchase Considerations And Comparisons
Power needs: Determine your essential loads (refrigeration, heating, sump pumps, lighting) and choose a unit with sufficient running watts and peak watts. A 12 kW class generator typically covers most homes during outages, but larger dwellings may benefit from higher peak watt capacity.
Fuel options: Dual-fuel and tri-fuel designs offer flexibility. Propane generally burns cleaner and stores longer, while gasoline can provide higher peak performance. Natural gas connections are convenient where available but may have lower available wattage compared to propane or gasoline.
Starting method: Remote/electric start saves effort during adverse conditions. Manual recoil starts are more economical but require physical effort in cold or adverse weather.
Transfer switch compatibility: A unit that is transfer switch ready or compatible with a whole-home transfer switch simplifies safe and automatic switching from utility power to generator power during outages. Ensure your home panel supports the appropriate outlets (L14-30R, 14-50R, etc.).
Safety features: CO detection, automatic shutdown on low oil, and covered outlets reduce risks. Look for rubber-sleeved outlets and proper enclosure design to limit exposure to hot surfaces and weather.
Run time and fuel efficiency: Review fuel tank capacity and estimated run times under typical loads. Larger tanks and smarter engine management provide longer operation between refuels, especially important for longer outages.
Noise levels and footprint: Some models emphasize quieter operation and more compact footprints, which can matter for residential neighborhoods or storage considerations. Consider placement, venting, and generator clearance requirements for safe operation.
Warranty and service: A robust warranty and access to local service centers can reduce ownership costs over time. Check for parts availability and manufacturer support lines when evaluating models.
Brand reputation: Westinghouse, DuroMax, and other established brands offer broad dealer networks and established parts supply chains, aiding long-term reliability and serviceability.
