Buying Guide for Whole House Gas Generators
Power Output and Home Needs
Assess your home’s electrical load to select a generator with sufficient running and peak wattage. Higher running watts ensure continuous power to key appliances, while peak watts handle startup surges.
Fuel Type and Availability
Generators may support gasoline, propane, natural gas, or combinations. Tri-fuel and dual-fuel models provide flexibility, helping ensure fuel availability during emergencies. Consider fuel storage and convenience.
Run Time and Fuel Tank Capacity
Longer run times enhance backup duration during outages. Larger fuel tanks support extended runtimes but add weight. Balance runtime needs with portability.
Starting Mechanism
Remote electric start simplifies operation, especially for frequent or emergency use. Manual recoil start can serve as backup.
Outlets and Transfer Switch Compatibility
Check the number and type of outlets to match your appliances and home wiring. Transfer switch ready models facilitate safe, legal home integration.
Safety Features
Look for automatic low oil shutdown, carbon monoxide detection, and GFCI outlets. These features protect the generator and users.
Warranty and Support
A good warranty period ensures coverage for defects and peace of mind. Also consider brand reputation and customer service availability.
Noise Levels and Portability
Some models include noise reduction technology for quieter operation. Portable generators should have handles or wheels for mobility, but standby generators prioritize installation location over portability.
Considering these factors will help you choose a whole house gas generator best suited to your home’s power backup requirements and emergency preparedness.
